Media Player Classic - BE Win32/x64

[zamar92]

Hi,

I'm trying to add folder structure to Playlist, and play saved by Tuya Camera on SDCard unencrypted .media (https://developer.tuya.com/en/docs/iot-device-dev/tuyaos-package-ipc-device?id=Kcn1q62z79dla#title-4-Directory%20and%20file%20structure) fragments of a sample static room video with music, but only raw H264 video can play with no NHNT encoded audio heard. The same folder/file sample collection plays fine with audio in Android Tuya Camera app, since it gets audio codec info from extra files present in the attached folder structure.

Any help or ideas? I need that to play camera surveylance footage on a Windows PC from a mounted camera SDCard, but Tuya doesn't offer Windows app, and no other Windows app I tried seems to do the job.

I hope this ShotCut forum thread (https://forum.shotcut.org/t/media-files-of-a-surveillance-camera/45348/14) helps a little: It may be possible to multiplex everything to an MP4 file, GPAC/MP4Box should support it if the info file is present as well.

[SirMaster]

Just Atmos. Which is also just an extension layer, so ignoring it isn't a big issue with most sound systems. I doubt that many people have a proper Atmos 7.1.4 speaker setup. Most have a crappy soundbar with a few small speakers in it that emulate surround.

DTS:X as well which adds extension object channels onto DTS-HD.

I know many people using MPC players for their home theaters and have 7.1.4 and even larger systems, so they definitely rely on audio passthrough to their AVRs.

[zamar92]

I hope this ShotCut forum thread (https://forum.shotcut.org/t/media-files-of-a-surveillance-camera/45348/14) helps a little.

Thanks for pointing at it and GPAC & MP4Box. I tried, but GPAC player didn't play this audio by default, and I get lost trying to figure our right MP4Box cmdline to play or demux the .media fragments. May be someone can help figuring it out using the above attached Sample? Would be nice if MPC-BE can play such sequence videos from SDCard and possibly allow to save them to disk in a popular format, since there is no Windows app for that, but demand, looking at the web .media and .data cam files playback forum threads, is as large as cheaper no ONVIF support cams consumer base. :)

If the video is not opened with the built-in page parser and is redirected to yt-dlp, the audio track is not loaded if a different format is selected in the opened video.

That way there is no problem. Selecting different format loads the audio track.

1- I know about this but I think the problem is not related to the built-in web page parser.

2- Sometimes videos on YouTube do not open. It is not possible to give the video address because it is not always the same video.

Thank you. The problem seems to be fixed.


@Devs

I noticed a few features added from MPC-BE to MPC-HC and I think there are more to come. Mouse features, merged play/pause button...

The feature I'm looking for the most in MPC-BE is the status bar video/audio info/fps and other options in MPC-HC.

Are you planning to add this or something similar? I would love to see this type of feature.

Speaking of youtube videos, something strange is going on.

Using the built-in web page parser:
When the video finishes playing, MPC-BE freezes and stops reacting. Clicking the close button does nothing. Clicking it a second time pops up a dialog "The application is not responding. Do you want to end this process?".
No stacktrace files or minidumps are created. No errors in the Event Viewer either.

When using the yt-dlp parser everything is fine, no freezes etc.

Thanks for looking into this, Alex! Mea culpa! I reset my settings and now everything is perfect, no freezes. I wonder what went wrong.

Regards!

[LuckyJim]

Sorry for the spam, folks! Just wanted to let you know, that the culprit for the freezes at the end of the videos was LAV Splitter Source (v0.79.2.27).
Disabling it and enabling the internal source filters fixes the problem.

Regards!

ETA: LAV version

Two questions:

1. What exactly do the swap effect (discard/flip) options do? Does it have any effect on video quality?

2. For MPC Video Decoder, what is the best decoder option to use? Is NVDEC preferred if I'm on an NVIDIA GPU?

[v0lt]

1. What exactly do the swap effect (discard/flip) options do?
For D3D11 see DXGI_SWAP_EFFECT (https://learn.microsoft.com/en-us/windows/win32/api/dxgi/ne-dxgi-dxgi_swap_effect)
For D3D9 see D3DSWAPEFFECT (https://learn.microsoft.com/en-us/windows/win32/direct3d9/d3dswapeffect)
Does it have any effect on video quality?
No. It does not affect the picture quality.
2. For MPC Video Decoder, what is the best decoder option to use?
This is a stupid question because all decoders usually produce the same picture. We recommend D3D11 decoder for better performance.
Is NVDEC preferred if I'm on an NVIDIA GPU?
Usually no. But you can have your own opinion.

[huhn]

discard d3d11 is bugged and will produce massive banding in 10 bit mode.

Good morning.
I have one question about mpc video renderer.
Is there a tutorial explaining how the MPC Video Renderer options work?
Thanks by advance and Excuse me if this is not the right place to ask this question.

maybe just ask what you want to know.
the default are fine the video renderer doesn't need special setup it works on pretty much everything and is the definition of efficiency.

"Settings Description
Use Direct3D11

The video renderer will use Direct3D 11 instead of Direct3D 9 whenever possible. Requires Windows 7 SP1; Windows 8.1 or newer is recommended.
Texture format

Specifies the texture format used for storing intermediate processing results.
Note: The 16-bit Floating Point format increases video memory consumption.
Show statistics

Displays an overlay with various statistics on top of the video frame. It is recommended to enable this option when taking a screenshot to diagnose issues.
DXVA2 and D3D11 Video Processor
Use for: NV12, P010/P016, YUY2, Other supported formats

Defines which formats will use the DXVA2 or D3D11 video processor when possible.
DXVA2 and D3D11 video processors are typically faster than shaders and also support deinterlacing.
Note: Interlaced frames are usually in NV12 or YUY2 format.
Double the frame rate when deinterlacing

When deinterlacing, the output frame rate will be doubled.
Use for resizing

The DXVA2 or D3D11 video processor will be used for resizing frames.
This method is fast but may reduce quality.
For example, Nvidia GPUs use bilinear interpolation (lower quality), while Intel GPUs use bicubic interpolation (better quality).
Request Super Resolution

Requests the use of Super Resolution if supported by the graphics adapter and drivers.
Expected to work on Intel Gen10+ and RTX 30/40 series GPUs with updated drivers.
Shader Video Processor
Chroma scaling

Algorithm for upscaling the chroma component from 4:2:0 and 4:2:2 to 4:4:4.
Upscaling

Interpolation algorithm used for enlarging frames.
Downscaling

Algorithm used for reducing frame size.
Use the "Upscaling" method to reduce the frame to 50%

The Upscaling algorithm will also be used when reducing the frame size to 50%.
Use dithering

Enables dithering when reducing color depth from 10-bit/16-bit to 8-bit.
Dithering can improve the display of smooth gradients. However, the effect may not be noticeable on small screens.
Use Blend deinterlacing for YUV 4:2:0

Applies simple Blend deinterlacing to frames marked as interlaced.
HDR Settings
Prefer Dolby Vision over PQ and HLG

This option prioritizes Dolby Vision over PQ (Perceptual Quantizer) and HLG (Hybrid Log-Gamma) formats.
By default, this is disabled, as the image quality change is minimal, but GPU load increases significantly.
Passthrough to display

Passes HDR video metadata directly to the display.
Requirements:

Windows 10
HDR10-compatible display
GPU supporting HDMI 2.0b or DisplayPort 1.4

Windows HDR

Automatically switches the display to HDR mode.
Requirements:

Windows 10
HDR10-compatible display
GPU supporting HDMI 2.0b or DisplayPort 1.4

Subtitle and OSD brightness

Adjusts the brightness of subtitles in HDR videos when Passthrough to display is enabled.
Convert to SDR

Converts HDR video to SDR for proper display on non-HDR screens.
SDR display nits

Defines the estimated brightness level (in nits) of the SDR display, used for HDR-to-SDR conversion.
Other Settings
Swap effect

Determines how frames are displayed on the desktop.

Discard mode is generally more stable.
Flip mode can be faster.

Use exclusive fullscreen

May resolve stuttering playback issues on additional monitors.
Wait for V-Blank before Present

Ensures precise frame output timing, which may improve playback smoothness.
This setting helps the SyncOffset graph better reflect frame timing irregularities.
Reinitialize D3D device when changing display

When moving the window to another monitor, the Direct3D device will reset and reinitialize.
This helps resolve issues in multi-monitor setups.

Is it a correct translation ?

[y8jhoM]

Why does madVR report doubled vertical resolution when used with MPC-BE built-in filters? With LAV filters, a 1920x800 video is seen as 1920x800 by madVR (in Ctrl+J overlay), but with MPC-BE filters the same video is seen as 1920x1600 (in Ctrl+J overlay). No upscaling is applied in either case.

Also, is there performance benefit to using MPC-BE native video filter DirectX 12 Copy-Back compared to LAV video filter DirectX 11 native? I use madVR that does not utilize DirectX 12 (yet).

[v0lt]

@ikarad
I don't see the point in writing a machine translation here. Windows has the Edge browser, which has a built-in web page translator.

@s0meone_new
Thanks. Updated.

@y8jhoM
The "Copy-Back" mode for the hardware decoder will always be slower than the "Native" modes. It's obvious.

[huhn]

what does "wait for vblank before presentation" and "adjust the frame presentation time" exactly do?

[v0lt]

@beter
Thanks. Updated.

@huhn

Wait for V-Blank before Present
The renderer will wait for a V-Blank event before calling Present. This allows for more accurate frame output timing. This allows the SyncOffset graph to more accurately reflect frame output jitter.
This setting may affect video smoothness. Disabled by default to avoid annoying users with a sawtooth graph.

Adjust the frame presentation time
The renderer will wait additionally before displaying a frame to more accurately hit the required display refresh time. This setting helps smoothly play interlaced video with double the frame rate (50/60 fps) on displays with a high refresh rate (120 Hz and higher).

[huhn]

first of all thanks for your time.

does it simply display a frame every let's say 25 sec with a 25 FPS source and the windows "DWM" to handle that. or is some type of sync still done but not shown?

can it even do that with the Wait for "V-Blank before Present" aren't these very fixed timings?

or is this more of a case to even have proper frame times instead of it been presenting the frames when it is done rendering?

example 240 hz monitor 24p source and video render times are 1-5 ms if it would take 5 ms and it would directly present the frame after rendering it will create some "judder" in the process because it is now a vsync interval late?

[v0lt]

does it simply display a frame every let's say 25 sec with a 25 FPS source and the windows "DWM" to handle that. or is some type of sync still done but not shown?
The logic is as follows.
1. First comes the general synchronization based on the CBaseVideoRenderer code.
2. Then we do everything that needs to be done with the video frame, apply shaders. Something will actually be done at this stage, and something will wait for the Present call. This depends on the implementation of the pipeline in the video driver.
3. IDXGIOutput::WaitForVBlank (https://learn.microsoft.com/en-us/windows/win32/api/dxgi/nf-dxgi-idxgioutput-waitforvblank) <- wait for vertical blank
4. IDXGISwapChain::Present (https://learn.microsoft.com/en-us/windows/win32/api/dxgi/nf-dxgi-idxgiswapchain-present) <- give the command to display the frame
Waiting for V-Blank has a positive effect on the statistics graph because Present can return control "instantly".

Perhaps statistics should be collected differently, but we don't have another working and tested solution.

can it even do that with the Wait for "V-Blank before Present" aren't these very fixed timings?
Possibly, but we have no way to test this.
Testing fast processes at runtime is very difficult and you can get very different results on different hardware.

[huhn]

what a nightmare and that's barely the surface.

i was thinking about screen recordings i have no 120 HZ capture card to make it even more clear.

i have a feeling i can see it does a frame repeat cadence of 4 6 4 5 6 4 instead of 4 5 5 5 5 5 when it reaches 8 ms sync offset with a 23p file at 120 hz.

[huhn]

there is a lot of new hardware decoding support from microsoft und that needs new code to make it work.

so the fact a card can do something is not that relevant at first.
a 1000 series maybe even 960 can do 444 predictive lossless h264 we still can't do that to day with DXVA or D3D11. main 444 has been added which may work and is new but a 1000 series is an ancient GPU.
nvdec can do that for example because it could do it for like forever..
Maybe you could get one of those Blackmagic cards as a birthday present for yourself. :)
afaik they don't have a single one with 120 hz support.
and a really good one cost a grand too that's a lot for just playing around.

GPU D3D11 decoding works.
But I encountered an issue: If image is scaled to 1920x1080 from 3840x2160p image is blocky.
Scaling till 3071x1727 is blocky, when scaling from 3072x1728 and above image looks fine.

Thanks.
Interesting. Can HEVC_MAIN10_422 output to YUY2 for compatibility or is it a dual 8-bit and 10-bit decoder (like AV1_PROFILE0)?

[clsid]

Yes, it's a dual encoder/decoder.

How is AMD and Intel with its new generations in this topic?
Intel Arc B580

[huhn]

VCE 4.0 got AV1 encode that's pretty much it.
some very old codecs where removed this is really not a problem.

that was RDNA 3 not 4 the official stuff i get for RDNA 4 is well nothing.
it has AI AVC encoder stuff and improved AVC encoding...

there is currently nothing that is needed/missing so yeah.

for more details a card is needed.

ohh and yes are supposedly not using a low end scaler for DXVA downscaling now.

the stuff nvidia and intel added is very cool but niche stuff.

[ryrynz]

I know it's only just been added, but any plan for a visual indication that Low Latency Audio mode is working with MPC Audio Renderer? Tnx

Not planned.

Not planned.

Was thinking maybe something simple, like greying out the buffer value or locking to 10ms.


Commit 6ee02c3 - added information about "Low Latency" to the status when using this mode


Legend, thanks.

typical.
i ask if they could add correct chroma subsample scaling position. answer was also not planned and it was added nearly immediately.

Does MPC-BE contain a video decoder for ASV1 (ASUS V1) video? Peeking into the mpc-be64.exe, I do find that FourCC. But when I try to play an AVI file containing video encoded with that codec, MPC-BE seems to fall back to trying system-installed codecs.

I have ffdshow installed, and it crashed while decoding ASV1 was disabled; when I enabled it in the ffdshow decoder, MPC-BE played that video without issues. But if the MPC Video Decoder built into MPC-BE supports this format, I guess it should not even try to use ffdshow?

PS: Maybe ASV1 belongs to a group of decoders which is by default disabled (unchecked) in the MPC Video Decoder configuration?

[v0lt]

[pirlouy]

Hello,
I've noticed some (minor) visual things. I don't know if anything can be done (don't feel obliged to answer).

1) I'm discovering HDR world recently (10 bits, DV etc. I still don't understand the usefulness compared to old SDR 8 bits but that's not your problem).
With my GPU (Geforce 1060), in Nvidia Control Panel, I can't select 10 Bpc, there's only 12 (Nvidia driver limitation before Geforce 3000 FWIR).
When I use 12 bpc, with MPCVR, each time OSD appears/disappears, I have 1 black screen flickering (and dropped frames some seconds later, I guess linked to a buffer reinitializing).
This flickering is also present when MPC-BE Progress bar at bottom appears/disappears, but since it's part of UI, I guess it must be normal. But I though OSD would not cause this black screen flickering. I wonder if it's the case with 10 bpc in nvidia drivers.

2) Concerning subtitles, I've noticed that "Outline Border width" is not scaled like the text.

Subtitle In Full Screen:
https://i.imgur.com/lleD7ly.png
Subtitle in smaller window:
https://i.imgur.com/BGxcJI5.png

If possible, the outline thickness should be scaled like the text.

3) Also I guess it's not possible but is there a way to have a minimum size for subtitles ? In general you configure the settings for fullscreen, but when alterning between watching full screen and small size, you have to change settings. I've tried to use scale xy% setting but it looks like its aim is to change the aspect ratio of text, not the size for different renderer sizes.

Some captures with my settings if it helps:
https://imgur.com/a/hBJxzZK

[v0lt]

@pirlouy
Text subtitles can be simple, stylized (rigidly tied to the frame size), mixed and redefined. And to do everything well is a very difficult and possibly unsolvable task.
You can try an external subtitle renderer - XySubFilter (or one of 3).

Look's like driver bug.

[clsid]

Enabling exclusive mode in the renderer can help with that, for at least the seekbar.

Does your desktop output Dolby Vision to your screen? If so, showing GUI elements on top of video might cause it to temporarily switch from HDR to DV and back. Solution is to force Windows to always use HDR. Like by disabling DV in your monitor.

[pirlouy]

My example was with SDR video (sorry I should have been more precise). I enabled 12 bpc for HDR10 videos but the problem is with SDR videos.
But I agree with Alexsoid, it looks like a bug with the driver and 12 bpc. In fact, colors are right when in window mode, but not when in fullscreen (except when OSD is present). So the flickering is because it cycles from window mode to fullscreen mode.

Maybe you're right and enabling exclusive mode would help, but when you start doing tricky workaround for minimal gain, it's dangerous. I prefer to stay in 8 bits, I'm OK with losing extra infos, as long as HDR videos don't have wrong colors.
The obvious fix is to buy a recent GPU and test 4K 120Hz 10 bits. But at the time, GPU was accessible at 150 €. Still waiting for this price (I know I'm dreaming).

@Volt: I'm OK with internal subtitles, as long as I have a working setting for fullscreen. I understand subtitles rendering can be complicated.

[Sunspark]

If your display is listed as supporting HDMI 2.1, the best thing for you to do would be to purchase an active displayport to hdmi 2.1 adapter. The hdmi ports on your card are 2.0b which is more than half the speed of 2.1. The adapter would fix that and open up more refresh rates and depths.

[ryrynz]

Will there be a AI upscaler added to MPC-VR at some point?
Nvidia Super Res is just too sharp for me to want to use it.

Any way to change the main toolbar size like in MPC-HC advanced settings ?

Did anyone ever manage to figure this out?

I really do like the Seekbar thumbnail preview feature of MPC-BE, but the toolbar is just so tiny!

All I've found so far is guides on how to replace the toolbar buttons entirely with funky colourful user generated ones... but I like the default buttons.

I just wish they were bigger, is all.

Although it is way too late to figure it out: The "Including subtitles" option of "Save image" on MPC-BE is not working anymore on MPC Video Renderer. Last working stable build of MPC VR is 0.8.9.2318.

Hi guys, gosh I love MPC-BE so much and am wondering if there is a way to disable the "eject" button on the GUI. I keep accidentally hitting it while jumping around on the seek bar and a windows explorer type window keeps opening. I would like to keep accidentally hitting it but nothing happens ;-)

Be careful or disable (hide) the toolbar.

No way to disable buttons on toolbar.

[Grimsdyke]

I have a somewhat similar problem. When right-clicking in the UI and moving the mouse cursor down to options I sometimes go to far and click on "exit".
Yeah, my fault - I know, but I think it would be really cool if it would be possible to fine-tune MPC-BE to personal tastes/needs. Like moving "options" to the top.

[Aleksoid1978]

Once again - YOU CANNOT CONFIGURE THE BUTTONS. What's not clear about that?

But anyone can try to implement this and send us a pull request, we'll see.

Hi, I'm having a problem with YouTube videos for a few weeks now and it's driving me crazy
After I play many different videos (aprox an hour of 3/5 minutes videos), MPC-BE stops playing every single video I try to play, and I got a message from YouTube saying that I am a bot and I need to sign in
It must be a YouTube thing, since as soon as that happened I tried opening the same video on an incognito tab in chrome and i got the same message
So my question is: Is there any way to log my YouTube account into MPC-BE so i can get rid of this problem entirely or is there any workaround so i can solve this issue?

Thanks so much, and sorry if my English isn't the best

[Helleik]

This is not a yt-dlp forum.

Ok no problem, sorry about that
So, is it there any other way to do it with MPC-BE? It would be much better since yt-dlp takes too much time loading any video while the built-in web parser is way faster and better
Thanks

[Aleksoid1978]

Yes, watch in browser.

[LigH]

Just to finish the detour: yt-dlp is much more elaborate in supporting tricky cases and gets very quickly updated when YouTube changes counter techniques again... my "download best AVC + AAC in MP4" code in a Batch script is:

yt-dlp.exe -v -f "bestvideo[vcodec^=avc1]+bestaudio[acodec^=mp4a]/best[vcodec^=avc1]" --cookies-from-browser firefox -- "%1"
(several browsers are supported by name; the "--" is the last parameter before the URL or video ID so it may contain a '-' dash without causing issues; ffmpeg is required in the same directory, phantomjs helps too)

Back to MPC-BE.

[SeeMoreDigital]

You can place the new version of 'yt-dlp.exe' in your MPC-BE x64 folder. And create a link to it: -

https://i.ibb.co/HpD7gKH3/Screenshot-2025-04-30-152222.png

[v0lt]

You can place the new version of 'yt-dlp.exe' in your MPC-BE x64 folder.
Copying is not necessary. You can specify the full path to yt-dlp.exe in the "Executable file" field.

[Sunspark]

The cookies thing is good advice. Read up on it. I needed to learn how to do that because I discovered (especially with newer stuff) that without the browser youtube cookie it will use a lower-resolution video.

[LigH]

Using cookies is also necessary if you want to watch or download clips with membership or age restrictions.

[huhn]

is it really unfeasible to add the same cookie support for the internal parser directly from ytdl?

[v0lt]

@Sunspark, @LigH
As far as I know, you can now specify the path to the cookie file in the yt-dlp.conf file.
Something like this:
--cookies C:\\TOOLS\\yt-dlp_cookies.txt
More about the configuration file: https://github.com/yt-dlp/yt-dlp/#configuration

is it really unfeasible to add the same cookie support for the internal parser directly from ytdl?
No. We do not plan to do questionable things in terms of user data security.

[LigH]

Yes, you can export cookies from the browser to a text file (e.g. via browser add-on in case of Firefox) to load them from there into yt-dlp; but: There may be times when you need to export them again or YouTube will notice that they got obsolete in the meantime.

When I view a MP4 video (originally from Samsung Galaxy Smartphone) with MPC on Win10 then black letterboxes appears at the side (see snapshot in attachment).

But here we must remember that the player has a minimum window width for correct display of the menu and toolbar. Therefore, for small window sizes, black fields will always be (except for the "Minimal" preset).

Are there any long term plans to add Dolby Vision support ? User at Guru3D forums uploaded a version of MPV that plays Dolby Vision files on Windows 10/11.

https://forums.guru3d.com/threads/dolby-vision-wish-we-could-get-this-to-work.454293/page-8#post-6330858

I am on Windows 10 and I tried several DV files and they were displayed correctly, with no green/purple tint. The player itself is a piece of crap though. Not intuitive to configure and it stutters during the play of good amount of videos I used to test it with, both DV and non DV. Only silver lining is its ability to correctly display Dolby Vision files.

[huhn]

try it with mpcVR as the video renderer.
there are a lot of different DV types some will work.

[MR_b]

I ask for help: I have a problem when I use mpc-be to save a YouTube video in the webm format.
The download takes place correctly, a video file and audio file is created. But the next union, creates a small file (262 bytes) which obviously does not contain the video. In the MPC-BE installation folder there are ffmpeg.exe and ffprobe.exe. If I use ffmpeg.exe from command line everything works properly. The problem seems to be in how MPC-be manages ffmpeg. I also tried various versions of ffmpeg.exe but the problem remains. Thanks to those who want to help me.

[v0lt]

Provide a link to the video and a screenshot of the "Online media service" settings.

Added:
I think you are using VP9 video with AAC audio. MPC-BE tries to merge it into WebM format, which is impossible.

This may be fixed in the future. The best solution is to change the audio or video format in the settings.

[MR_b]

Thank you v0lt. The problem is with any video. For example: https://www.youtube.com/watch?v=BvAUQsbKnLI
For clarity I report what I do. I open the video (Open File/URL). I select one of the WEBM(vp9)... (Navigate > Jump To). The video is correctly played. Now Salvo (File > Save As).
What remains after downloading is a small file.
In the " Online media service " settings no change has given good results.

I think it would be best for you to reinstall MPC-BE 1.8.4+. During installation, make sure that the "MPC Video Renderer" component and the additional "Reset settings" task are enabled.

[Amuat]

Why does DV use shaders unlike PQ/HLG even when using D3D for resizing? This I guess is very much subjective, but what are your personal thoughts on whether it is worth it to prefer DV and use the chroma shader, and is Catmull-Rom the obvious choice or can Bilinear be better in some cases?

[v0lt]

[Amuat]

Thank you, also another question: I tried the RTX Super Resolution option, but it makes the image look washed out like it was supposed to be watched in HDR. It seems a bit odd as there are separate options both in the MPCVR settings and NVidia CP for the SDR to HDR function, which were both unselected. If on the other hand I only request super resolution in MPCVR and leave it off in NVCP, it does absolutely nothing (though OSD says it is on, with an asterisk at the end). What am I doing wrong?

[Zarxrax]

When playing certain old videos, mainly mpeg or wmv files, the player does not seek properly. When seeking the audio will play normally, but it might take 30 seconds or more for the video to start back up. In some cases it seems like the video never starts again.
I only noticed this recently after installing windows 11 and a recent version of MPC-BE. Previously I was on windows 10, and probably using at least a 2 year old build of MPC-BE. Not sure if there is some setting I might need to tweak, or if maybe there was some change in the decoders or renderer that might effect this.

[LigH]

Specifically in case of WMV, I would like to guess that it probably does not contain a valid keyframe index chunk. It may help to remultiplex it. I guess ffmpeg can handle it; I once bought "Machete" to do that.

In case of MPEG PS or TS, they don't have index chunks, so the player needs to estimate a seek position by extrapolating an average bitrate value in a header, which may be invalid; remultiplexing (maybe to MKV) should improve that as well.

[thrawnrulz68]

Has anyone been able to get MPC-BE to remember to "Show milliseconds" if that option is checked and then the player is closed and reopened?

In order for mine to show milliseconds, that option needs to be rechecked every time the player is open.

I author codes for WindTracks dependent on exact frame times often having many instances of the player opened simultaneously repeatedly opening and closing them.

I too wish for a persistent MPC-BE retain showing millisecond setting. Fwiw, MPC-HC does in fact retain the setting... but not MPC-BE.

When using DirectShow, you are not guaranteed to get accurate timing for each video frame.

"Correct monitor/desktop AR diff" (video frame menu) <-- What does this function actually do? I see the window get slightly higher.

[Klaus1189]

What display resolution do you use? And which model of monitor/TV/projector?

[Amuat]

I make very extensive use of the remembering of last position where you stopped a file function. Probably a stupid question, but it doesn't by any chance eliminate a file from the tracked list if you "rewind" it to the beginning? Also, if you have a 5 min minimum length (to use my own setting as an example) for a file to remember its last position, does it even register shorter files you open, or is it as simple as just keeping count of any previous x (whatever you've set) number of files opened regardless of either their length or whether you've "rewinded" them, but only actually starts where you last stopped for the files where the set minimum is met?

Are there any test videos I can use to check if the problems are with my files?

[v0lt]

@Klaus1189
The size of subtitles is small and we download them all at once. But with audio tracks it is impossible. Therefore we create only one connection for the preferred audio track.

Some 2160p HDR videos work perfectly in window mode but get a little bit colder and lifeless when i put them on fullscreen.
1. It looks like you're using exclusive fullscreen.
2. It's also possible you're using DXVA2 instead of D3D11. Press Ctrl+J and see what is written in the statistics.

I've started using RTX HDR (sue me), but I'm a bit confused with the settings. It seems like this (https://www.reddit.com/r/nvidia/comments/1b03yfg/rtx_hdr_paper_white_gamma_reference_settings/) is outdated now after subsequent updates and the default settings should be correct, but then again it is patently obvious that at least saturation should still be -25, at least if you don't want everyone to have excessive sun tan. But is 0 contrast really the right way to go now? And if so, should the mid-gray value be based on the +25 contrast column if 0 contrast is the new +25, or have mid-grays also been adjusted so that I should follow the 0 contrast column?

Resetting the shader list.
1. Install MPC-BE using the installer (requires administrator rights).
2. If you have previously used MPC-BE, open the %APPDATA%\MPC-BE folder and delete the Shaders and Shaders11 subfolders.
3. Launch MPC-BE. The Shaders and Shaders11 folders will be restored for your account.

Haha, if I could make my own fork I'd be the happiest man alive(well, you know) but alas I cannot.

So, I guess the only way is google & download, is that right..??

Most mkvs already have them inside, and the ones that don't, it isn't really a challenge to find them.

MPC-BE can display a movie's title from MP4 metadata in the progress bar header.

Which of the MP4 meta tags is used? I would like to add it via an FFMETADATA1 file I am already using to add chapters to the MP4.

I already tried to extract metadata from files where it works to discover which tags they used, but it was insufficient.
The global tags "comment" and "title" don't seem to work ("title" in a [CHAPTER] block sets a title for a chapter successfully, though).

[LigH]

It seems to be not an issue of MPC-BE, but of ffmpeg: If I try to add metadata from one file which contains both global tags and chapters, the tags get recognized but not inserted properly.
I want to prefer the metadata file, though; using explicit command line meta tags is not suitable for me.
Testing more for a separate thread...

I've found the weirdest fix to a bug that I can remember. There has been discussion in Reddit for example about how for many users RTX HDR limits the max nits in the app options to a much lower value than the monitor is actually capable of. I have this problem, and guess what fixes it every single time? Not restarting the NVidia App, not turning HDR off and back on again, not rebooting the system, but simply opening Windows settings and navigating to the screen where it shows your monitor's peak brightness among other specifications. It's almost as if NVidia needs to be convinced of your monitor's capability: "Oh, okay, I guess you really can go further". What is frustrating is that it keeps forgetting, have to do this every time after turning the monitor off and on again. I'm not even sure it has any actual effect, the bug might just be that it only displays the wrong info rather than actually messing with how RTX HDR works (should do some testing at some point), but I do this just in case as long as they (hopefully) fix it for good at some point.

[clsid]

The primary reason why it takes them so long to fix is because people report problems on random forums like Doom9 instead of directly to NVIDIA.

i can't find the deband shader.

and dx11 does not allow pre scale shader. deband shader should be best when applied to source resolution.

Hi,

I've tried using AI to port a DX9 debanding shader to DX11.
Model: Qwen3-235B-A22B

Known issues:
- Not accurate enough
- Too simple, may not be able to handle complicated scene

NVidia has acknowledged this problem and said it is looking for a solution. This was quite a long time ago already, but I doubt it would hurry them along if I complained about it now. Anyway, this is a function integrated into MPCVR, maybe someone here will even benefit from this bandage solution, who knows.

Hi guys, using MPC-BE 1.8.5 (portable version) and noticed that for .wmv files it is using LAV as the splitter (source filter) and some files out of sync. So I went into MPC settings and looked under Source Filters and see no option for .wmv (asf) files whatsoever but under Audio/Video decoders there are options for wmv. Hmmm, am I blind or is there no wmv selection/option for source filter? I would like to use something other than LAV to split wmv files due to the out of sync problems (perhaps use internal W10 wmv filter) but I can't figure out how to select that... Thanks :-)

[v0lt]

So I went into MPC settings and looked under Source Filters and see no option for .wmv (asf) files whatsoever but under Audio/Video decoders there are options for wmv. Hmmm, am I blind or is there no wmv selection/option for source filter?
Method 1.
1. MPC-BE > Options > External Filters. Do not set the priority to "Prefer" for LAV Splitter Source and LAV Splitter.
2. LAV Splitter Configuration > Input formats > asf = uncheck
After these steps you will have a system "WM ASF Reader" filter for ASF/ WMV connected.

Method 2.
1. Add the necessary filters to the list of external filters.
2. Do not change the priorities for filters. You can even uncheck them.
3. Specify the filter for the desired format in the "Priority" settings panel.
If the source filter supports this format, it will be used.

[clsid]

In my experience, if using LAV Splitter for WMV, you also need to use its A/V decoders for best result.

Hi v0lt, thanks for your detailed answer :-) but no luck with either Methods 1 or 2...

Method 1:
Never added LAV to external filters so it's not listed there
Did go to LAV splitter config and unchecked asf
result : wmv files still play with LAV doing the splitting (even though asf is disabled in LAV filter settings)

Method 2:
Added WM ASF Reader to list of external filters
Did not change priorities (later tried prefer but that didn't change the below result)
Under priorities - for wmv I added the ASF Reader
result: wmv still play with LAV doing the splitting (even though I left asf disabled in LAV splitter config as per Method 1)

Wow, so weird. Guess I am stuck with LAV until I install w11 or W12 ;-)

[clsid]

Check this registry key (if exists) which controls preferred source filter:
HKEY_CLASSES_ROOT\Media Type\Extensions\.wmv

But maybe it actually is a different format with wrong file extension?

Provide a sample that has issues?

Hi, yes that registry key exists. I have hundreds of .wmv & .asf files & they all have the problem I described (I checked a few of them that I had used for the testing with MediaInfo to ensure that indeed they are wmv type). Am sure something got borked on my W10 system, I only noticed this problem because I saw some wmv out of sync and checked the filter chain ;-)

[Sunspark]

If you use software decoding for the wmv codec files, is it still out of sync?

[JarrettH]

In MPC Video Renderer, is Jinc2m scaler supposed to be the best option? I often see sharpness mixed up with "best," but I recall Jinc (paired with anti-ringing) was for a long time a good all-rounder in madvr. Would Jinc2m be equally safe scaling HD content and DVDs/standard def? Thanks!

[huhn]

it's not safe.
it's also not comparable to jinc in madVR.
try lanczos3 and jinc2m and use the one you like but lanczos3 will ring and jinc2m will go over board. lanczos3 could be combined with AR from jinc2m and improve it quite a lot.

It looks like the file association doesn't work with Windows 11. I've tried associating MPC-BE with all file types in the installer and the application itself, but neither does anything.
Windows itself allows me to change the default app, but only for each file extension individually...
Can this be fixed so that the file association feature in MPC-BE works again to associate all files extensions at once?

[LigH]

If I'm not completely wrong, this is a "security feature" already in Windows 10: Applications are not any more allowed to assign file associations, only the user may do that in the Windows Control Center dialog.

MPC Video Renderer 0.9.11.2440 (https://github.com/Aleksoid1978/VideoRenderer/releases/tag/0.9.11)

Changes:
Fixed a crash when exceeding the frame size increase limit using the DXVA2/D3D11 video processor. In this case, frame size increase using shaders will be used.
Fixed a crash when using exclusive full Screen and the "Exclusive full screen on additional window" setting in MPC-BE for two graphics adapters.
Added "Deinterlacing" setting for DXVA2 and D3D11 video processors.
Eliminated frame copying (ZeroCopy) when using the DXVA2 hardware decoder and DXVA2 video processor for Direct3D 9 mode.
Eliminated frame copying (ZeroCopy) when using the D3D11 hardware decoder and D3D11 video processor for Direct3D 11 mode.
Fixed filter registration and deregistration using included CMD files.

PS: MPC Video Renderer 0.9.11 is included in the MPC-BE 1.8.5.77 installer.

You could try right-clicking on the exe and select run as administrator, and then see if the file associations take.

[Lestex]

Zdravo Dev. Longtime fan of the software, thanks! Used it daily for maybe 10 years! When you think about new features, please consider these:

1) (edit: already there) Keep "Show Milliseconds" on after restart (now it resets to default and hides milliseconds again every time)
2) "Copy time code" keyboard shorcut to copy current time code to clipboard. Ideally HH:MM:SS.MS when "Show Milliseconds" is on and HH:MM:SS when it's off, but just one that includes milliseconds would be really great. I need milliseconds all the time for ffmpeg and must type the numbers manually.
3) "Delete file" keyboard shortcut for quickly deleting files. Often need it a lot.
4) A shortcut for Zoom 150% (or custom user value). A lot of times Zoom 200% is too much, Zoom 100% is too little, and Zoom 150% would be just right. Just like in that fairy tale!
5) OSD: separate background transparancy from text transparency, allow to change OSD position to other corners, allow to make text shadow thicker. I have a problem with my left eye so I prefer top right myself. I also wanted to set solid OSD text with thick shadow and no background, but changing "Transparent" also makes the text transparent. Not really important.

If you can do anything of these when not busy with more important things, it would be awesome. I would use all of them a lot. If not, I understand of course, no worries! Sorry for my bad English and thanks.

(edit) Just saw in the changelog that 1.8.5 now keeps "Show Milliseconds", lol. Thanks again! Also question: what's the best quality resizer? Lancroz3?

[LigH]

There is no objective "best" for everyone's subjective taste. That's the reason why there are so many different kernels for scalers. And doing it in realtime, possibly by GPU shaders, is a different task on top...

Lanczos3 is a kernel which can produce a quite sharp looking result, at the cost of possible ringing artifacts around edges. You need to decide for yourself if you can tolerate, even enjoy that result.

[huhn]

lanczos2/3 with low ringing should be addable

jinc2 is just reading the 3 centered pixel of the 16 it reads calculates the biggest and smaller of these 4 clamps them followed by a lerp with the ar strength. simple but it is very very effective.

the lanczos code seems to be reading 5 pixel in one dimension so 25 in total for x4 pixel output so translating that should be the problem. especially for some one like me that can barely read c code.

How can I change album cover scaling settings for flac/mp3 files? they always default to something like 512x512. Currently, album cover size is tied to video scale. I have resize window to video scale set to 100%, but even though some of my music files have 2560x2560 cover images, it keeps scaling to a tiny 512x512 thumbnail. Would be nice if there was an album cover setting mirroring resize window to video scale options - so I could keep video scale at 100%, but set album cover to fill window (rather than resize window to 512x512 every time a music file is played). I have attached two images,

one showing default behaviour,

the other showing the window if it was not resized (I set the window size to 457x785 in order to accommodate playlist)

Bonus feature request: It would be really convenient if there was a setting to "auto display the playlist, revert to hidden/unhidden state otherwise" if you open a playlist file or use the "play folder in MPC-Be" feature from the explorer right click menu etc.

[Aleksoid1978]

The size of the cover does not affect the window scaling in any way, it only works for videos.
Regarding the new option for displaying the playlist - no, there will be no such thing.

Has something changed in the more recent versions of MPC BE / VR? I've been using Windows HDR set to 'allow turn on' for a long time and it would always switch windows HDR on when I watch an HDR video, then automatically turn it off once I close the video. Now it switches on, but does not turn it off.

Not a huge deal but a little annoying. I use windows in SDR... I only want HDR on when I watch movies.

edit: It's happening in older versions of MPC BE / VR too, versions that I used before without this problem. Something must've changed in Windows? Any help would be appreciated.

HDR not turning off is a bug in recent Windows update.

If I have a Samsung TV that has no dolby vision support, and have plenty of files that have both DV and HDR, is there any benefit of leaving "Prefer Dolby Vision over PQ and HLG" enabled on my settings? I think dolby vision is converted (i can see on my stats that the input is the dolby vision layer), but would this be a "superior" HDR than the normal HDR? or on the contrary, I am getting an incorrect picture and should be disabled on my case?

Another question, why does a file that only has DV profile 5 (no hdr fallback), plays correctly even if "Prefer Dolby Vision over PQ and HLG" is disabled? shouldnt the image appear purple and green??

Use what you like best and what works best for your system. You know best. If you don't see a difference, use the default setting.

What GPU do you use?

[v0lt]

Hmmm, seem to be anything Windows and/or driver related (Intel) because EVR and AVR-CP don't work as well. Strange ...
You may have overridden these values ​​in your driver settings.

In MPC VR, you can disable all formats for the DXVA2/D3D11 VideoProcessor. In this case, YUV to RGB conversion and brightness and contrast adjustments will be handled using shaders.

I've noticed a minor glitch I've never seen before with MPC (both BE and HC). It could totally be only me, so I just report it if somebody else noticed it too.

When I enter fullscreen, the window player appears up-left for some ms before displaying the fullscreen image. OK it's really short, it's easier to noticed if you are on 23 Hz refresh rate.
Reproduced with MPCVR and EVR so not linked to renderer.
I'm on Windows 11 with a Geforce 1060.

Here is what I managed to capture for 1 frame. What you see up-left is what will be in full screen some ms later.

Yes, this happens sometimes, it’s nothing to worry about.

I've been using AltDVB (https://www.altx.ro/2025/06/altdvb-v25/)with MPC standalone filters since MPC Video Renderer support arrived. This was to see how the filters worked, and as I expected, they weren't having much trouble. There are some visual issues, which I think you can fix. I'm using MPC Audio Renderer specifically for its low latency. The MPC Audio Decoder also couldn't decode AAC audio channels. It has no issues with AAC LATM. Here's (https://drive.google.com/file/d/18J6e0t_dN6WcGWbPCtRFKjQYN4KprGW9/view?usp=drive_link) the recording I got with AltDVB.

I checked your file in MPC-BE – everything plays fine.
If you're having problems with AltDVB, ask the program's author.

[ryrynz]

Any possibility of MPC-BE supporting GLSL shaders? I'd really like some options when it comes to the somewhat limited upscaling options in MPC-VR.
Ether that or some upscalers added that are a lot more GPU intensive. Not a fan of Nvidia's Super Resolution.

[v0lt]

Any possibility of MPC-BE supporting GLSL shaders?
Use a DirectShow video renderer that uses OpenGL. It may also support GLSL shaders.
If such a video renderer doesn't exist, create one yourself or hire someone else.

[huhn]

current shader support doesn't support the change of the resolution.

this is why you can use glsl with mpv in directx mode: https://en.wikipedia.org/wiki/Standard_Portable_Intermediate_Representation

or technically HLSL in openGL/vulkan mode

Sorry if this is the wrong place as this thread is specifically for BE, but since it has been advertised to me as practically also for HC, here goes:

Linking the alpha channels for subtitles hasn't worked for me for quite some time now. I enable it in the menu, apply the changes, close the menu and then open it again only to see it unchecked. I currently have the latest beta and the problem still persists. Anyone else have this or is there something wrong with my setup?

used to play in an earlier version of MPC-BE but not in v1.8.6 or v1.8.7, [Win10P x64].

The "QMPlay_length1=xxxx" is a private to player QMPlay2 flag, perhaps MPC-BE is tripping over that.
The playlist plays just fine in Potplayer current.

EDIT: Multiple, "Failed to render the file" messages.

EDIT: Sometimes does play at least one of the YT clips properly. [Not always the same ones, only tried v1.8.6 where it sometimes plays some tracks ok]
EDIT: The tracks it does play ok seem a bit random [can change on each playlist play].
No big deal if you cannot fix, I can use Potplayer.


EDIT: Quite recently QMPLay2 had some problems playing playlists clips [under Windows], Y.T. seems to have changed some stuff, resulting in longer period to parse meta data or something.
The problem seemed related to some versions of yt-dlp.exe under windows only [QMPLay2 uses yt-dlp.exe, linux ver$ yt-dlp was ok].
QMPLAY2:- https://github.com/zaps166/QMPlay2

EDIT: Some notes I took a while back for yt-dlp.exe, current version is ok in QMPLay2

Your "original" playlist loads and plays fine.

According to this yt-dlp issue, a big change is coming soon where you need a javascript runtime for downloads.

You might need to add the Deno module to the player.

https://github.com/yt-dlp/yt-dlp/issues/14404

[LigH]

A while ago I already mentioned that yt-dlp best co-exists with ffmpeg and phantomjs in the same directory (when we talked about browser cookies to allow access to membership or age restricted videos). I did not know Deno then, yet... good to know, I guess.

MPC-BE v1.8.6 and same playlist, as for stuff in BLUE above, ie sometimes plays some of the files.

I note in your posted image, it only loaded 6 of the 8 clips into the playlist, ie failed on two of them.
EDIT: They (v1.8.6/v1.8.7) usually do add to playlist ok, only usually fails on clip render.

Hi guys, I've just stumbled over this [FreeTube releases, See Aug 23] :- https://github.com/FreeTubeApp/FreeTube/releases

v0.23.8 Beta Pre-release
Summary

This hotfix release fixes the This video is unavailable errors.

Important

Video loading times have increased because YouTube's servers now return errors if you attempt to start a video before the preroll ads have finished. While FreeTube skips the ads, it still has to wait until the preroll ad sequence completes before the video can begin playing. This is a limitation imposed by YouTube’s servers, and it also affects other YouTube-related projects, such as yt-dlp.
Fixes

Wait for pre-roll ads to finish in /player request by @absidue in #7887


Perhaps reason for some clips to sometimes fail render when playing *.pls playlist.
EDIT: Freetube currently fails on all clips. (??? is not a function )

[LigH]

Well possible; yt-dlp regularly displays messages like:

[download] Sleeping 3.00 seconds as required by the site...

Most often 3 or 4 seconds.

Hello!

I use the absolutely excellent (a lifesaver) MPC Video Renderer (0.9.13.2451 (2025-09-15).
With PotPlayer I get a really good picture, in all formats including UHD but...
The strange thing is that in UHD, (HEVC) I can both play and pause PotPlayer and take a screenshot, CTRL+E.
If I play a Blu-ray [BD] or .mkv, (AVC), I can only take a screenshot if PotPlayer is playing, if I pause the player I can't take a screenshot.
If I turn off MPC Video Renderer, screenshot works.
Is there something I can solve in the settings inside MPC?
PotPlayer completely refuses if MPC is the renderer.

Best regards,
varekai

[Aleksoid1978]

Somehow I guessed that I would get that answer...

What other answer did you expect? I checked it in "normal" players, everything is fine.

[varekai]

What other answer did you expect? I checked it in "normal" players, everything is fine.
Please define "normal" players.

[huhn]

just a guess:
- This software includes a video decoder based on FFmpeg (http://www.ffmpeg.org) which is licensed under LGPL license.(To review the LGPL license, look for LGPL.txt in install directory) The modified FFmpeg source can be downloaded from http://potplayer.daum.net/devel/ffmpeg.zip
never was there never will be there and even if it was there it wouldn't be enough

the VR has a way to make a screenshoot as can be seen in mpc-BE/HC if they don't want to use that so be it.

[LigH]

@varekai:

Probably some that rely on DirectShow only. MPC-BE/HC use a few specific filters with a direct API, IIRC.

[v0lt]

Please define "normal" players.
DirectShow players that use the IBasicVideo::GetCurrentImage method (https://learn.microsoft.com/en-us/windows/win32/api/control/nf-control-ibasicvideo-getcurrentimage) to take screenshots.
In some situations, DirectShow players can use IExFilterConfig::Flt_GetBin("displayedImage") (https://github.com/Aleksoid1978/VideoRenderer/blob/41cc61ba3233af5f6aed5b119f6086b750c0ff50/Include/FilterInterfaces.h#L61) method.

The question of why PotPlayer can't take a screenshot, unlike other players, should obviously be addressed to the PotPlayer developer.
We have no ability or desire to debug code that we don't have.

[LigH]

Side note, may not belong exactly to this question:

If a player uses the Hardware Overlay renderer, a screenshot back from the renderer may not be possible because this is a one-way renderer, the overlay area in the VRAM cannot be read back to the PC, its content only goes out to the video connectors (that's why it is written so fast). It could only be taken from the video decoder.

[v0lt]

Thanks to all the translators. The translations have been updated.

If a player uses the Hardware Overlay renderer, a screenshot back from the renderer may not be possible
MPC Video Renderer uses Direct3D 9 and 11. Surfaces or textures named "Overlay" are not used.

[huhn]

d3d9 overlay support has been removed by nvidia. and amd never supported it.

it was the best... going to miss you.

[CruNcher]

Yes this was part of the secure media render pipeline preparation for HDCP/DRM encryption this was a requirement by microsoft and nvidia enforced it somewhere i think in the range of the 17x driver actually it was the overlay mirroring
ATi/AMD was in a lot of ways there much better prepared as well when some other decisions where made in the complete security restructuring also in preparation for the combined XBox Windows Universal Apps architecture ATI/AMD was much better prepared, still Nvidias Engineers could compensate many problems fast.
It was kind of crazy how ATI/AMD could never really utilize all this efficiently having a complete Hardware Design Advantage 1 Generation after the other, but after D3D9 and R300 ATi/AMD never could succeed and get in front of "The way its meant to be played".
And then Nvidia Designed this combined VPU IP Core ATI/AMD never saw the Day of Light against.
I send so much bug reports to ATi/AMD i waited so loooong for any answer i send one to Nvidia and you could be sure it was fixed in the next Driver (who's engineers flooded here and promoted their API and took feedback and bug reports so serious owned everything in how the VPU crushed AMDs entire Stack Design and Framework,Feedback support,Communication and entire Team Engagement)

Just crazy they maybe have a in theory less efficient raw hardware design but the machine who compensates it, finds optimal solutions in its limits and ensures the quality runs so well OILED.

[v0lt]

MPC Video Renderer 0.9.15.2463 (https://github.com/Aleksoid1978/VideoRenderer/releases/tag/0.9.15)

yes because they steal the code. there is a reason they are treated like they are because they are just scums. even if the link would work they would still not uphold LGPL they are objectively bad actors.

before 404 this was something like ahfdsjgybv no this is not a joke.

[varekai]

I have no idea what this "ahfdsjgybv" means??
Software history is full of open source code being "stolen".
Some popular open source software became commercial on a large scale in one way or another.
I know of many such examples, these people, now filthy rich individuals and companies are the real scums!!
But despite stolen opensource code and all that shady stuff, PotPlayer is a fantastic free media player!
If for example VLC, MPC-HC or MPC-BE could achieve what PotPlayer can, I'll happily switch.
Until then... time will tell...
If the Korean Daum Potplayer developers are shady as you say, they still maintain and regulary provide updates free of charge.
Also they are kind enough to answer emails and provide valuable information. I have contacted them many times.
Sometimes I get useful solutions, sometimes just the answer; reset to default...
Sadly there isn't any forum, it used to be but not anymore.

Do a simple google boolean search:
"what is the five most popular free media players of all time"

Anyway, I'm happy and satisfied with my setup, finally(!), PotPlayer, MPC Video Renderer and madVR work as I want and I can switch renderers whenever I want,
The video image on the two PC Dell displays/Sony TV I get is fantastic, the new TV and UHD are the icing on the cake...
Consider this the end of the thread, no need beat a dead horse anymore...

Thanks and kind regards,
varekai

they put a file up and hit the middle of the keyboard to have something in there as "source code".

It is rather strange behaviour for Korean Devs you would rather guess from Chinese Devs ;)

though without doubt it was always on a very high technical standard it solved a lot of problems efficiently others lacked it was especially robust i remember with transport streams, and i designed my first Fullscreen GUI for it with a lot of layer function complexity.
And often when others had problems then that wasn't the case for it and i often cross checked interop and bugs with it, it certainly has a very "stable" Design Methodology yet it is very complex.

And it had this change the renderer on the fly feature no one else had, that was very impressive.
And im pretty sure they thought a lot of gui osd rendering and sync impact on the video playback inside of Windows with and without DWM.

Hello, can someone please help with a problem I'm having? I currently use MPC-BE in conjunction with MPC-VR, LAV Filters, and SVP (Rife) for motion interpolation on my Samsung VRR television. While the variable refresh rate feature engages successfully with certain files, its behavior is inconsistent even with the same file, for some files dont engage at all. I have exhausted all combinations of settings in my attempts to find a consistent solution. I have been unable to make it work consistently. While I know this is straightforward with MPV, I would prefer to continue using MPC-BE for my playback. Any advice would be greatly appreciated. Thanks in advance.

In any case, you should contact SVP support or their forum (https://www.svp-team.com/forum/).

vrr is not supported

[Drakko01]

First thanks to take the time. I doubt you need LAV Video Decoder.
In any case, you should contact SVP support or their forum (https://www.svp-team.com/forum/).
I familiar to the forum, I've been a participant on the SVP forum for some time and have engaged in many of the discussions there.

Video File → MPC-BE (Source) → LAV Filters (Decoder) → VapourSynth Filter (SVP with RIFE) → MPC Video Renderer → Display

To my understanding the MPC Video Renderer is responsible for engaging VRR here.The MPC Video Renderer can communicate directly with the graphics card driver to enable VRR. For this to happen, the renderer must be configured to use a presentation mode that supports VRR, such as "Flip Mode". Display synchronization: The frame rate produced by the SVP and RIFE interpolation is not always perfectly stable.By leveraging VRR, the MPC Video Renderer tells the display to wait for each new frame instead of trying to refresh at a fixed rate, thus eliminating stutter and tearing.

I have managed to achieve this, but the process is inconsistent and does not work every time and with every file in my library (mostly 4K DV/HDR/HDR10 MKV files) This is why I am asking for assistance here; I hope that those with more technical knowledge can help me find a reliable solution or maybe be interested in taking a look at this.

As already said above, VRR IS NOT SUPPORTED by the video renderer!!!

The only tiny miniscule chance to get support for it is to donate a proper VRR capable monitor to the developers, which you are not going to do.

So final conclusion is that VRR IS NOT SUPPORTED. Period. End of discussion.

My intention was not to upset or disrespect you in any way. I am very grateful for the work of developers like you, and I used MPC-HC for a long time. However, I moved to MPC-BE for this exact reason. I know that VRR is not officially supported, but whether it is or not, it appears to be working for me—at least to some extent. My TV engages VRR and remains engaged without problems when it does. I have even tested this with the G-SYNC compatible indicator from Nvidia to confirm it is actually working.

[huhn]

it is not working.
engaging VRR and working VRR are to different things.

[v0lt]

Video File → MPC-BE (Source) → LAV Filters (Decoder) → VapourSynth Filter (SVP with RIFE) → MPC Video Renderer → Display
I would remove "LAV Filters (Decoder)" from here. The built-in decoder supports D3D11cb, if you need a "copy back."

To my understanding the MPC Video Renderer is responsible for engaging VRR here.The MPC Video Renderer can communicate directly with the graphics card driver to enable VRR.
MPC Video Renderer doesn't know anything about VRR and doesn't switch anything for this purpose.

[Drakko01]

Fair enough. You are absolutely right, and I take back my previous statement. My goal now is simply to make sure VRR engages consistently. What should I be focusing on to make that happen?"

Even if it only means that the TV reacts differently

I know you have no interest in continuing to talk about VRR, but if I can use an analogy: if I'm buying a car, I want a mechanic by my side.

So thanks again

[huhn]

your mechanic would tell you to stop putting gasoline in a diesel.

OK, I I'll give it a try, but if I remember correctly, that way you suggested engages VRR less often, or not at all most of the times.

MPC Video Renderer doesn't know anything about VRR and doesn't switch anything for this purpose.

i won't discuss that, because i don't really Know what engages this mode on my TV. I only assume it has somethig to do do with the Flip presentation mode of the MPCVR or other option in that part of the configuration.

Do you have any suggestions for a setting o cause that woukd ensure VRR engages every time in case like this.
I will share any of my configurations if it means getting VRR working (and I refer to engages with consistency

You need the $500 VRR firmware enhancement upgrade for your TV.

I have a contact that can deliver it to you for just $300, if you pay upfront in Bitcoin.

Okay, I get it; you're not interested in this topic at all. 'VRR' is a bad term here. If you ask anything related to this, all you'll get is mocking replys. I was doing my best to be respectful and hoping to get some insight from 'knowledgeable people' to help me achieve the same result I've mentioned consistently. But that's fine; I'm not going to waste your/my time trying to do it here, at least.

As you've already been told, you or someone else can help solve this "problem" by sponsoring developers to purchase a device with VRR support.

[Amuat]

Well, it turns out that you shouldn't output even 10-bit with auto 8/10 integer on 8-bit videos, let alone 12-bit with 16-bit FP, at least with my monitor. Kind of strange that I noticed this only now, but when going fullscreen there was this quick shift from brighter to paler colors, which is reproducible even with a different player, whereas outputting 8-bit gives consistently the brighter colors, windowed or fullscreen, MPC or a different player. What is going on here? It can't be because of dithering, right? Is it what huhn said awhile back, that most TVs just aren't good with 10-bit (I have Philips 806, FWIW)?

[huhn]

this option is for the internal bit deep only the presentation only seems to care about the driver setting and matches that to some degree.
the presentation line in the OSD shows the output format.

if the internal buffer changes the image not in terms of dark details/banding what sounds like a bug not sure if that can even happen with HDR because 8 bit is plenty for PQ but if someone knows any real world test to show otherwise you know where to find me.


for internal buffer in terms of math everything below 16 is flawed when YCbCr->RGB is needed. i do not know if it is every buffer only some or what ever that option actually sets.

Your Philips OLED includes HDMI 2.1, eARC, VRR, ALLM, FreeSync Premium, and G-SYNC compatibility. Therefore, what is your definition of a device with VRR support?
By the way, I didn't ask for support, integration, or development, but rather information to better understand how to get VRR working consistently.
Your RTX 4060+, your OLED, is pretty much all you need to test.

let's try it one more time.
it never used free VRR it never trigger VRR it never did anything related to that it just got confused that's it. it is still using v-sync it is still not correcting A/V sync what so ever because to do that with a video renderer you need to do a lot of stuff unlike a computer game they don't even have the same master clock...

because it does not support VRR end of story...

Can someone explain why when watching VRR videos, all videos have a fixed frequency?

VRR videos are insanely rare i can make one if you want one i doubt i still have the old one with up 120 HZ still lying around. i talk about real VRR here changing the frame rate every frame.
do you mean the reported frame rate which is an AVG?

or do you mean why watch a fixed frame rate video on a VRR display?
that would be to avoid judder and also fix video audio sync because user are to lazy to match refreshrates.
if VRR is even remotely accurate enough for that...

there is quite a number of mixed refreshrate DVDs but they need a realtime detelecine that can handle that first.

Can someone explain why when watching VRR videos, all videos have a fixed frequency?

I don't know if this is an honest question or a way of saying that VRR for movies doesn't make sense.

I'll play along, just in case

To clarify the original point: While testing different settings with MPC-BE, SVP, RIFE, and MPC-VR, Spider-Man: No Way Home look different. The initial assumption was that this change resulted from a new NVIDIA driver or something. The movements and pans seemed smoother, even for SVP's interpolation (yeah I know ,many people hated).
Adjusting the volume with the TV remote revealed that the TV's on-screen display frequency counter was not fixed at 120Hz.

So I tried other movies. showed same behavior in some cases, but not in others. Movies that had worked previously sometimes failed to do so again. Closing and reopening the player would sometimes resolve the issue, and the frequency would no longer be fixed at 120Hz."

WHY, its a mystery to me, that's what brought me here , to try to figured it out.
Its important, maybe not, or maybe for those looking to play interpolated videos on TV with VRR capabilities, its an option since its not supported for most video players.

I'm asking honestly because I don't understand the purpose of VRR for movies. Videos have a fixed frame rate. The best option is to set the player to automatically switch the frame rate to match the video.
And everything will be smooth. When watching on a TV, it's also advisable to use the exclusive full-screen mode.

[Drakko01]

I can't discuss the technical part because I don't fully understand it, and it's impossible to show it, at least from a distance. For anyone in the same room, I can pinpoint exactly where to look to see the differences.
I been using svp since its crowdfunding campaign on Indiegogo. The main goal of any SVP user is smoother playback. After RIFE was implemented, everything became better, so the hardware was improved to match my needs(as far as my money will go). With that said:

I know the video frame rate is fixed and that switching to match the frame rate its exactly what i try to do with all this. In this specific case, using SVP+RIFE x3 @72fps and x4 @96fps produces frame rates the TV doesn't accept, and that's when the TV's VRR mode comes into play. Alex Battaglia of Digital Foundry says it perfectly in his video "VRR Is Not A Magic Bullet," if the frame change is very sudden or abrupt. The use of exclusive fullscreen is and has always been mandatory for me.

SVP+RIFE x4 @96fps - TV 120hz microstutters are easily perceived.
SVP+RIFE x4 @96fps - TV VRR mode OSD counter fluctuating nearly eliminates all of those microstutters.

you know FSE is fake on win 11?

if VRR has enough resolution (we talk about 0.001 ms or something like that).
it could remove frame drops from audio video sync issues and makes frame rate matching pointless.

adding good VRR support is utterly insane in terms of difficulty.
nvidia clock deviation between an onboard audio device is like 0.00167% that'S the one i currently have that's 1.2 hours that's often much worse usually ~24 mins for nvidia HDMI audio and HDMI video VRR could fix that.

just like reclock or smoothmotion fixes this issue but we neither have to resample the audio or blend the video we get both untouched.

it could also be used for DVDs and BD that are 24 and 60 mix (relative rare).
i can immediately give you a sample that switches from 3:2 24 hard telecine to 2:2 PsF even a blu ray. that's technically VRR. or you just use 120 HT and realtime IVTC.

i personally don't think it is worth it. it's made for games no one will notice if a frame has the wrong timing from time to time but for video it needs to be utterly precise to be useful.

just imagine the extreme case VRR is only fixed frame rate like it can do 23 24 25 HZ so for a usually 24000/1001 file and it would do a lot of 24 hz and every ~1000 frames a true 23 HZ creating a jitter i would call that VRR useless for video. for games that's good enough.

you could just use madVR SM or reclock and move but VRR could be better then both. it also supersedes custom refreshrates and every device that is not a PJ is pretty much VRR.

[clsid]

VRR is crap at low framerate, so you should use at least double/triple fps with repeated frames.

And docs say VRR doesn't work with exclusive mode.
https://learn.microsoft.com/en-us/windows/win32/direct3ddxgi/variable-refresh-rate-displays
Setting present flag is easy. Question is how to get supported fps range, so renderer can choose the best custom "fixed" target framerate to base its timing on. Assuming the regular refreshrate is maximum, renderer could double/quadruple input fps as long as <= maximum.

[huhn]

yes i skipped that part.

lfc is supposed to fix that but yes it would also need to multiply the frame rate to the highest possible number that is still 10 FPS below max. newer HDMI devices report the range.

it's a mess.

I usually pre-transcode my titles with advanced code I've inserted and don't have lots of hours using real-time. Fwiw, I use SVP+RIFE/TensorRT x2.5, MPC-BE/HC, 4.25 model, no FSE, and no VRR with zero problems. Perhaps your x3 and x4 are just not up to the task since your display doesn't support the resulting rates? What will result is pulling up/down which always produces judder/microstutter perhaps tearing etc. I cured my problems when 1st setting up by reading both SVP logs but you've probably looked at yours too. The 3rd transcode log is helpful also.

Your Feedback was appreciated.Transcoding files is not a solution for me, because the resulting files will not trigger VRR mode and as this mode best handles these ranges and i don't mean exact clocks

I use similar settings that you except for the multipliers, you probably use 60hz for your display , that's kinda less problematic.


The core of my issue was that the tv fail to enter this mode for some movies, that's the point I was trying to explain,not knowing the cause, came looking for someone to give me a clue how to fix it , anyway...

A workaround that I Found through testing. The library now has 35 files that activate VRR estate, compared to a previous 5

The main difference between them is DV versus HDR10 only or HDR only
I always use vapoursynth filter https://github.com/CrendKing/avisynth_filter/releases/tag/v1.4.7 this work for the HDR10 but not for the DV ones

I switch to vapoursynth filter 1.4.7# svp or 1.4.8# svp this ones work to the DV files

This isn't an optimal fix, but it's a functional workaround for now, allowing the addition of more DV+HDR10 files without issue.

Concerning my previous post: it was not 8 vs 10/12 bit itself that affected colors, but the fact that on the latter ACM is automatically on. Noticed this as I was on 8-bit and still, for whatever reason, the colors suddenly changed back on the fly, and as I suspected, the OSD now showed ACM was also back on. Glad it did though, as I had already started to notice that I actually preferred the more subdued colors, and quick research seems to indicate that ACM is actually more accurate though less vivid, if I'm not mistaken?

[huhn]

ACM take color information from somewhere and does correction depending on that.

but if the TV would know any of that it would just do it by it self. and how would you even get accurate information in the first place.

on my S90C red is just turned orange the TV is calibrated anyway so doing anything would undo that so what is the point of it again ahh yes to objectively ruin image!

so yes "calibration" information are taking and applied that are for what ever reason supposedly not applied by the TV.

maybe useful for gaming display that do not have any processing power what so ever and are tuned for low input lag and missing an sRGb mode making it better then nothing in that case.

[clsid]

If colors are dim ONLY in fullscreen, then this can help:
Right-click on your player .exe > Properties > Compatibility > enable "Use Legacy ICC Color Management"

[huhn]

that disables ACM and is what i use.

[clsid]

It doesn't disable ACM, but app behavior is similar to as if disabled:
https://learn.microsoft.com/en-us/windows/win32/wcs/advanced-color-icc-profiles#display-icc-profile-compatibility-helper

MPCVR already calls m_IDXGISwapChain4::SetColorSpace1 function when outputting HDR. So technically it should be ACM compatible. But maybe this function call is failing. Use a debug build and make a log with DebugView tool.
https://github.com/Aleksoid1978/VideoRenderer/wiki/View-debug-log

@Aleksoid1978
Can you add a log line when m_pDXGISwapChain4->CheckColorSpaceSupport call indicates that it doesn't support DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020 ?

ACM assumes the renderer outputs sRGB (unless told otherwise) and converts that to the displays colorspace.

@amuat/huhn
Does the issue only occur with HDR output?

[huhn]

i only test SDR so yes it happens with SDR.

the issue has to be my TV telling windows just none sense.

if you mean with sRGB also the transfer function?
mpcVR is currently not outputting sRGB transfer function neither is madVR (can't even do it).

[clsid]

Try with this test build (https://www.sendspace.com/file/786du8).
This one also calls SetColorSpace1 API in case of SDR output.

[huhn]

still broken with MY TV:
https://ibb.co/Ld7KvQWD

edit: red in paint is not red anymore and it renders the color different compared to the screenshoot where both have applied ACM.
now i tried to take the same image from the same palyer and now it is not applied to the screenshoot anymore.
if you want a proof i can get the colorimeter out.
inconsistency in calibration what could eb better...
/edit

mpc-hc has disabled fullscreen optimisation and lagecy color management mpc-be has none of them.
your test file has been over written in both installs.

https://learn.microsoft.com/en-us/windows/win32/wcs/advanced-color-icc-profiles#display-icc-profile-compatibility-helper
the information here are not utterly correct.
this display is in SDR. i'm not using an icc and it still changes the image massively.
this is a wide gamut display but how would windows know that the gamut is calibrated to bt 709 which is it.

even if windows would assume bt 2020 red the red shown wouldn't be bt 709 red in bt 2020.

BTW. i had to install lavfilter so mpc-be can open a png... yes i reset mpc-be to make sure i didn't do anything stupide.
not rerendering png all the time is a really good feature by mpc-hc while mpc-be is hammering the CPU with 8% load.

[clsid]

Windows acts based on ICC profile and if that is not present the EDID info. Maybe that is incorrect due to your calibration.

Your issue is probably a different one than Amuat's.

Edit:
BenQ recommends to disable ACM:
https://www.benq.com/en-us/support/downloads-faq/faq/product/application/monitor-faq-kn-00088.html

[huhn]

my point is this can generally not work.
if the TV knows the gamut it can also fix it just like windows is trying.

the edid will tell microsoft this TV can do a lot but even out of the box it is not that stupid it still tries to do bt 709:
https://i.rtings.com/assets/products/EqyIGxWD/samsung-s90c-oled/pre-colorspace-large.jpg?format=auto
windows doesn't know that and just ruins the image.

you can not change the edid all the time when you change the gamut good luck with that. https://www.rtings.com/assets/pages/2OMFbFp6/color-gamut-rec2020-color-space-settings-large.jpg
yes it can do bt 2020 red. and yes it has like 20 different edids because these are way to small and trigger with a different refreshrate or resolution but that's it.
you can try to use report bt 2020 in madVR or colorcontrol the TV may honour this.
but the other way around no there is no api. it's a dead end.
no matter what you do this system in it's current form can not work.

maybe if i set the gamut to native i will get something closer to red with ACM. but why would anyone do that if it has an auto function like any TV?

yes there are a lot of cheap gaming monitors that have a native gamut and that's all they use and they may even report that.
in that very very specific case yes maybe but with every device that is not handdown trash it has no clue what is going on.

would an API that can be updated constantly and say i except BT 709 gamma 2.4 or i except nothing but i'm ~xyz be cool? yes but edid is not that.

Anyone here asking about VRR? Try the test build. You should probably test it in fullscreen mode or exclusive fullscreen mode.

Well, then I don't know how to help. I tested it on my TV with a refresh rate of 120p, and opened videos with a refresh rate of 23/24/59p – everything runs smoothly.

[huhn]

wouldn't it do that without VRR?

if your screen has no VRR active refreshrate info play a 25p file and active "wait for v-sync before present" and the judder in graph should be gone and you should see a "smooth" video and not massive judder.

[Aleksoid1978]

I check on TV with VRR without wait for sync.

[Aleksoid1978]

set it to 100 nothing just judder then 280 and still nothing.

You can turn on statistics, but make sure you select "Increase font by window" and record video so you can see the judder.
Otherwise, I don't understand what you're talking about at all.

[huhn]

ohh that's simple.
360/24 is 15 there is no need to engage VRR. VRR range is 48-360 so it will engage nothing or LFC where the best choice is 360 and no VRR display will engage when you get close to the max refreshrate.

but 100/24 4.16 or 280/24 11.66 so 96 at 100 or 264 at 280 may engage. that's why i tried them.


if the system you are on is nvidia you can use conlorcontrol edit: https://github.com/Maassoft/ColorControl/releases /edit
driver settings -> 2 - sync and refresh -> gsync indicator -> on
i don't need it on my 144 HZ TV because it flickers so hard and reports utter nonesense i will know when it is active instantly.

i used dota 2 as a test and limited the frame rate and i get super stable frame rate in the game the TV reports ~70-90 with an limited of 80 so i can't wait for video playback with that...

[huhn]

i got mpc-hc triggering vrr.
with madVR...
it will not trigger with EVR or mpcVR yes your test build.

i broke pretty much everything that could be broken.
global vsync was disabled windows 7 compatibility mode is enabled.
i renamed the exe to not-mpc-hc.exe the normal install still doesn't trigger "g-sync".
and the results... https://ibb.co/1GF2cfbK what a waste of time play a 25 hz video at 127 when the screen max refershrate is set to 120.

there is a chance the driver will not allow mpc-hc mpc-be to disable vsync try to rename.

[clsid]

Don't use compat mode, as Win7 obviously has no VRR support.
Windows 11 has a "Known Game List" for VRR, so maybe try exe name of a game as test.

[huhn]

there is no special need VRR works with pretty much every game even games to old to consider and even on old OS versions the GPU driver just did all the work back then. disabling win 7 comp mode is breaking it!

also this: https://ibb.co/tpKBkT4J new screenshoot hope that one doesn't bug around https://ibb.co/W4DRpwPC
left mpc-be with the test build
top right mpc-hc madVR renamed and windows 7 compatibility mode
bot right mpc-hc madVR normal

this is just wow.

renaming to dota2.exe didn't change a thing.
edit: the normal mpc-hc version will show the same information as the renamed one for 1 frame until it changes back when the window is active.
mpc-be will show OS VRR off when selected...

the information is the support overlay indicator from colorcontrol.

The info in the top right one might be misleading. It says VRR type fullscreen. But player is in windowed mode, so affected by DWM. Afaik, Madvr also doesn't support VRR in any way.

MPC-HC has an application profile in NVIDIA driver. You can tweak that with ProfileInspector.

Edit:
Windows Settings -> System -> Display -> Graphics
Add player under "Custom Settings for Applications". Then enable "Optimizations for windowed games", to allow VRR with borderless fullscreen.

WinKey+G to show Xbox Game Bar. That has option to "remember this is a game". Maybe that helps too.

Edit2:
Does a VRR screen support refreshrate changes (to fixed value) in a smooth way, so without going black temporarily like dumb screen?
And if so, does it support "any" rate (in range) or just modes listed in driver settings?

[huhn]

win 11 doesn't do FSE anymore it's fake.
in that case mpc-hc/madVR thinks that there is currently fullscreen which is obviously false.

yes madVR doesn't support VRR just tested EVR and madVR to see if i can trigger it because every software can trigger it and mpcVR doesn't for some reason. madVR trigger VRR is actually an issue here it can go totally nuts.

i killed xbox game bar on all of my systems so i can not test that.
that is one of the reasons FSE is fake these days to get overlay work all times by "just" lying to the software that it is in FSE while the DWM will still do it things.

you need to disable fullscreen optimisation to get FSE back.

my system is currently setup to allow windowed VRR in windows and GPU driver.

[Amuat]

Hmm, I guess I need to do some proper comparison between ACM on and off. Didn't really have a proper sample size as all that was not in B&W during my brief stint without it was the Monty Python docu-series and a documentary on Incas (plus own footage but that is in no way good for reference for several reasons). The completely unnatural amount of red on people's faces on the former (don't know if it's a peculiar choice for the master itself or if I just had a bad version) even with ACM must certainly have affected my evaluation.

clsid, I'm also unable to say anything about HDR unfortunately. But what exactly did you mean by my problem? The fact that on 10/12-bit the screen flashes briefly with the bright non-ACM colors when turning fullscreen, or that ACM turned suddenly on and stayed on even when outputting just 8-bit? The former doesn't bother me at all although I guess it's technically an error, and as for the latter I'm waiting to see if the legacy ICC option keeps ACM completely away.

huhn, I'm stupid enough not to be clear on whether you are applying the TV's wide color gamut on SDR content, but I guess not?


[edited "bright ACM colors" to "bright non-ACM colors", sorry for the lapse.]

[clsid]

ACM likely got turned on after a graphics driver update. There are some complaints about it here (https://old.reddit.com/r/nvidia/comments/1o6dpc1/game_ready_studio_driver_58157_faqdiscussion/). You can turn it off in the Windows settings.

Please try the test build I posted a few comments back. I am curious if it has any (positive) effect on the colors in your original config (with ACM on and legacy ICC off).

[Drakko01]

Anyone here asking about VRR? Try the test build. You should probably test it in fullscreen mode or exclusive fullscreen mode.
I still haven't figured out how to test when VRR is working on my TV.

First thanks for taking the time to test. The build you summit it's the one has been used since posted on github, in gral I test nightly build as soon they come out. Maybe relevant or not , as i say in my previous post now the file that engage the VRR/LFC mode on my tv are the 2160p rips with DV+HDR , I leave some images of my settings and of my screen.

I think you got some true in there , as I say before it's no that mpcvr support proper vrr it's the mode of the tv thats handle better the playback, and for example my Rife x4 @96 fits better in the range in that mode as if was on normal @96 in 120hz

I use always "optimizations for windowed game " in both MPCBE and SVP
I don't know if i understand your question correctly. But I try to answered anyway.
For me fixed refresh rates like 60hz as some micro stutters
But this in between rates with vrr mode engaged are more smooth I think like huhn say LFC at x3 x4 and the tiny variables changes make this to happen.

I just checked - VRR/G-Sync doesn't work with madVR.

Edit2:
Does a VRR screen support refreshrate changes (to fixed value) in a smooth way, so without going black temporarily like dumb screen?
And if so, does it support "any" rate (in range) or just modes listed in driver settings?

let me explain this completely.

VRR never resyncs. an LFC 49-120 can do every refreshrate from 0.1 to 120 and anything inbetween with an unknown accuracy.
VRR has a refreshrate that is the maximum refreshrate this can be changed changing this needs a resync.
LFC is a default feature that both screens and the GPU driver can do and is engaged when the min FPS isn't reached and the max FPS is more then twice the min FPS.

49-120 LFC can work if i set this TV to 60 (49-60) it will not work and just tear below 50 making it useless.

all of this is simply use a multiplier when below 50
48 to low for VRR send 96 and there is no combination that will ever go over 120.

if you have a frame rate between 30-45 the monitor reports back quite some numbers fluctuating massively.
sending 30 as 60 works but sending 90 has lower input lag sending 120 doesn't because that's max refreshrate and needs vsync to not tear.

the max rate where VRR works is usually max -10 above that can work but doesn't have to work.

[huhn]

Я только что проверил - с madVR не работает VRR/G-Sync.

nope it doesn't only got it to trigger with extreme settings.
the information is mostly to show that the system and that player are currently capable of trigger it.

B) FreeSync / G-SYNC

Games create a virtual world in which the player moves around, and for best playing experience, we want to achieve a very high frame rate and lowest possible latency, without any tearing. As a result with FreeSync/G-SYNC the game simply renders as fast as it can and then throws each rendered frame to the display immediately. This results in very smooth motion, low latency and a very good playability.

Video rendering has completely different requirements. Video was recorded at a very specific frame interval, e.g. 23.976 frames per second. When doing video playback, unlike games, we don't actually render a virtual 3D world. Instead we just send the recorded video frames to the display. Because we cannot actually re-render the video frames in a different 3D world view position, it doesn't make sense to send frames to the display as fast as we can render. The movie would play like fast forward, if we did that! For perfect motion smoothness, we want the display to show each video frame for *EXACTLY* the right amount of time, which is usually 1000 / 24.000 * 1.001 = 41.708333333333333333333333333333 milliseconds.

FreeSync/G-SYNC would help with video rendering only if they had an API which allowed madVR to specify which video frame should be displayed for how long. But this is not what FreeSync/G-SYNC were made for, so such an API probably doesn't exist (I'm not 100% sure about that, though). Video renderers do not want a rendered frame to be displayed immediately. Instead they want the frames to be displayed at a specific point in time in the future, which is the opposite of what FreeSync/G-SYNC were made for.

If you believe that using FreeSync/G-SYNC would be beneficial for video playback, you might be able to convince me to implement support for that by fulfilling the following 2 requirements:

1) Show me an API which allows me to define at which time in the future a specific video frame gets displayed, and for how long exactly.
2) Donate a FreeSync/G-SYNC monitor to me, so that I can actually test a possible implementation. Developing blindly without test hardware doesn't make sense.

he immediately understood that trigger it is not even remotely close enough to do anything useful.

[Aleksoid1978]

It started with MPV, a popular player among SVP users. That was when TV Hz fluctuations were first noticed. After some trial and error, MPC-BE showed similar behavior, but with a narrower range. For example, with MPV and SVP at 96 Hz, the TV fluctuated between 88 Hz and 120 Hz. With MPC-BE and MPC-VR, the fluctuation was between 90 Hz and 108 Hz, usually closer to 96 Hz (94, 93, 97, 98, 95, 92, and so on)

Even games should think about when and how long to display a frame for, not just display it as fast as possible when it is ready.

It is more complicated for games, but all frame presentation methods should consider when and for how long a frame should be presented. Video renderers are used to simply displaying the next frame at the next V-sync, but given how fast VRR adoption is they will need to take more ownership of the frame display time.

Of course, a working implementation in D3D11 is another story, but VRR itself could be good for video too.

[pirlouy]

I'm with Windows 11 25H2 (26200.6899).
In MPCVR, when using setting Windows HDR: "Allow turn on (fullscreen)", it doesn't work, HDR is not turned on.

Of course, a working implementation in D3D11 is another story, but VRR itself could be good for video too.

and how should that be done?
if the GPU takes longer then the CPU consider this frame to be shown they have to show that slow rendered frame for to long they have no new one to show fast enough simple just from not rendering the frame fast enough and it is not like the CPU will wait for the current frame to be rendered by the GPU.

and all of these draw back are ok because it is still better then not doing it for games at least. that's why it isn't complicated for games at all could you do a better job and try to present frames only based on the CPU game state difference with a big enough frame buffer yes but VRR is designed to hove low input lag.

and next issue is can you take owner ship to that degree?

if i play 25 hz with mpv i get 50-100 with mostly 75 if it could take owner ship to that level it wouldn't do that it would be 100 for 120 HZ display and 125 HZ for 144 at all times no deviation that will show a different frame rate. if we can't even reach that point how does it even beat smoothmotion at 120 HZ or even higher refreshrates?

and yes cinema VRR was a thing for like one sub version of HDMI 2.1.

[Aleksoid1978]

I briefly tested G-Sync/VRR functionality. I loaded a game, in my case Path of Exile 1/2, in DX11/DX12 windowed mode, and G-Sync activated.
I loaded a video player with MPC-VR in DX11 mode, but nothing activated.
Honestly, I'm shocked; I don't understand what it needs :)

[pirlouy]

As Huhn explained, I also think high refresh rate with Smoothmotion (madVR like) is surely the best way to not perceive potential judder.
But your VRR test build showed me a strange behavior. MPC-BE hangs when it tries to enter this VRR mode. But to trigger that, I need to use "exclusive fullscreen" mode (as you warned us). So this exclusive fullscreen setting does something special.
And it's not the first time you advise FullScreen Exlusive move for playing movies. So I have questions about this "FullScreen exclusive" mode, sorry if it has already been discussed.

To me it's not using fullscreen exclusive because Windows 11 volume OSD appears when changing volume (with keyboard). This Volume OSD is a good indicator to me.
I know to prevent Windows from changing "Fullscreen Exclusive" to "Windowed Fullscreen", you have to "Disable Fullscreen optimizations" in EXE properties.
With mpv, "Disable Fullscreen optimizations", "d3d11-exclusive-fs" in mpv.conf file ("OnTop" is not the same, contrary to what the manual claims), when entering fullscreen, there's a dark screen for 1-2 second, and now if you change volume, there's no OSD, and I think this is the real (old) FullScreen Exclusive.

Just to be clear, I don't know if it's a useful mode, Microsoft thinks it is not and I don't want that 1-2 seconds delay so I don't use it, but I was surprised you advocated this mode whereas it does not seem to work as intended.

And more, even when MPCVR "fullscreen exclusive" mode is not enabled, it is still capable of displaying above some apps which have "OnTop" enabled. So I'm not sure to understand what MPCVR FullScreen exclusive mode brings as positive effects, but if you advise it, there must be a hidden reason I don't understand ?

[clsid]

Yes, it isn't truely exclusive depending anymore without that compat setting. But you can of course avoid third party overlays and OSD stuff.

It does also affect player behavior, because seekbar and OSD are drawn using the renderer instead of as separate windows.

[Amuat]

Please try the test build I posted a few comments back. I am curious if it has any (positive) effect on the colors in your original config (with ACM on and legacy ICC off).

Sorry, did not work for me at least. But I have to say, even though I said my own footage is not a good reference, the fact that I'm suddenly quite honestly blown away by it without ACM pretty much settles it for me.

In MPCVR, when using setting Windows HDR: "Allow turn on (fullscreen)", it doesn't work, HDR is not turned on.
Option works if I use "Allow turn On/Off" though.

I use "Allow turn On/Off" also. I have W11 HDR setting - OFF.
I have a problem I can't figure out using 24H2 and now 25H2.

In Windows settings/System/Power/Screen Sleep & Hibernate, Turn my screen off after 1 minute.

Play HDR video with MPCVR. Pause it. Let screen go into display off mode (takes 1 minute).

Jiggle mouse or enter key on remote etc. Display turns on. Un-pause video. MPC-BE crashes and the desktop is left in HDR mode.

Using madVR instead of MPCVR, un-paused video remains static but audio plays normally. I can seek and audio corresponds but video remains static stuck on the same frame I originally paused.

Fwiw, I use a few instances of MPC-BE all portable installs.

If I use Kodi internal VideoPlayer, everything works perfectly.

ChatGPT has no clue and I don't what else to do. Anyone have any suggestions outside of the obvious stuff. Been at this for days, not just hours.

[clsid]

As a workaround you could reload (Ctrl+E) the file after exiting display sleep.

MPC-HC has an advanced option to do that automatically after specified pause duration (or hibernate).

Honestly, I'm shocked; I don't understand what it needs :)

this is going to back fire but here we go

load a ton off pixel shader like clipping to full range until you have rendertimes of 10 ms.
now it will work... sometimes.

because now it doesn't try to render 1000 FPS your screen can't do but 100 sometimes.

this page here is just wasting your time: https://learn.microsoft.com/en-us/windows/win32/direct3ddxgi/variable-refresh-rate-displays
VRR can work with v-sync on mpv does it...
this is just for games to use windows API no game does need any of the code shown there i can literally take half life one and i will get it working if i some how get FPS below max of my screen.

to make VRR work with a video renderer you need to lie about rendertimes over and over again you need to somehow tell something that is very very variable to do exact 24000/1001 that isn't easy and there are no documents about how to do that because VRR isn't made for that.

i get VRR working in a game that doesn't really have a frame rate like emperor of the fading suns because the starting loading screen has like 5 FPS.

to make it work with an efficient video renderer like yours you will need to do so much much work by try and error i don't want to imagine that. y9ou have to stop showing a frame every v-sync.

here you go i loaded a totally sane number of 358 shaders and it is trigger VRR on fullscreen now. does that help anyone her now? no not at all.

[brazen1]

Thank you for the reply. (Ctrl+E) starts the video from the beginning. I just want to resume playback from where I paused it.

I'm really curious if this is just a problem on my system or if it's present for others?

Like Cap said, I can do this all day.:D

You want a simple way to activate the vrr mode, add vaporsynth filter as external in the chain ,in MPCVR settings * Use exclusive fullscreen and *Adjust the frame presentation time(work without this last one too)

It will be triggered, but not in the best way. For a 23.976 fps video, it will go around seventy-something hz.Similar to mpv but worse. By adding SVP and RIFE in the mix, you can achieve a much a better experience than madVR with Smoothmotion playback

The framerate is unstable because you are using too heavy settings. If that isn't blatantly obvious to you, then maybe you should watch some Sesame Street to learn some basic math.

Fans of interpolation should try out HopperRender (https://github.com/HopperLogger/HopperRender).

Yeah, with that response, you're as naive as Ernie.

Too heavy settings on what, exactly? This can likely be reproduced on a 4090, so what's the excuse then?


Putting that aside, i give this a look
HopperRender (https://github.com/HopperLogger/HopperRender).

[huhn]

when you have rendertimes over max frame rate it can just trigger VRR because you now have the requirement for game VRR

the fact that you compared smoothmotion with DVP frame interpolation and not to VRR speak quite a lot for itself because SM and VRR try to archive the same output goal while SVP does not.

[clsid]

I wish there was some kind of debug OSD in the renderer that shows details about its input including fps...
.. oh wait, there is ... /sarcasm

[huhn]

ms are missing even when it output 24 that doesn't mean it has rendertiems of 40 ms. it usually has like 1 ms and that's 1000 FPS for VRR so it does not care.

the stuff it current does for VRR is just useless.

[Drakko01]

It is hard to understand how someone with the extensive knowledge you have (and that knowledge is known, after reading and learning from hundreds of your posts over the years)
And even so you can't see or understand the point. Perhaps my explanation isn't clear, or maybe it's willful blindness.

The comparison with SM was in response to this...

As Huhn explained, I also think high refresh rate with Smoothmotion (madVR like) is surely the best way to not perceive potential judder.

The comparison between SVP and madVR's Smooth Motion is correct because both are software tools that attempt to address a specific video playback problem: motion judder and lack of smoothness.
The fact that they use different techniques is not a reason to dismiss the comparison, but rather the very basis for it.

Fans of interpolation should try out HopperRender (https://github.com/HopperLogger/HopperRender).

I guess you didn't read that I use SVP+Rife, otherwise I can't understand why you recommend this, the result is terrible in comparison.

There is nothing you can tell me that refutes the result I get by combining svp+rife+vrr mode.

Just wanted to share this: Some of the people in this very forum are the reason we're using this software(MPCBE,MPCVR), and the improvements over the years.Perhaps in another alternative reality this go different.

it never tried to do that and it doesn't do that.
i a perfect world madVR SM would look 100 % the same as frame rate matching. it can not beat frame rate matching in terms of smoothness it will also not remove the judder compared to frame rate matching.

frame rate interpolation like SVP can remove judder but it is not made to do that.
it'S job is it to create more frames nothing more in your case you are creating a frame rate missmatch on purpose doing x4 instead of x5 knowingly trying to fix that issue using VRR. if VRR could create perfect 96 HZ everything would be great.

and here is the reason this comparison has to stop. you can also just throw SM against it yes at 96 at 120 HZ because it is made for that.
i'm not recommending it because you do not have a display with about 200 hz but it will still work and remove the judder and nothing else it will not be smoother than 96 at 96.

because VRR and SM try to archive 100% the same thing.
there are very little things SM can but VRR couldn't in theory.

[pirlouy]

Just to be sure Drakko, this SVP+Rife outputs variable fps ?
And with maximum refresh-rate + madVR SM, result is not OK for you ? You really think VRR display would make this better ?

Good luck in your fight against 24 fps inherent judder. I've tried interpolation from TV, it's OK, but in the end, you're changing some parts and Tom Cruise (https://x.com/TomCruise/status/1070071781757616128) told me it was bad so I obeyed and disabled it ! Going to interpolation as no interpolation is as difficult as the opposite, but in the end, you avoid trouble accepting 24 fps limitation.

[strumf666]

it never tried to do that and it doesn't do that.
in a perfect world...
...movies would be recorded with higher and integer fps ;)

[Amuat]

VRR seems to be the topic of choice at the moment, but to annoy everybody, I'm gonna harp about ACM some more.

Am I to interpret the silence on it from everyone but huhn that pretty much everybody here is of the same opinion (that is, no good for something like the 806 that I use)? Maybe even that it's so obvious it's not even worth discussing? I've gone back to outputting 12-bit with 16-bit FP (for that post-process dithering), except that now I've turned ACM off in Windows settings and using legacy ICC on MPC exe, but really I'm just stumbling in the dark here at this point, so any informed input would be very welcome.

[Drakko01]

Huhn, everything you said in your last post is technically correct. And I have to say I appreciate this kind of response much more. Even though the end results for me are the opposite.

Just to be sure Drakko, this SVP+Rife outputs variable fps ?

-Not variable, but the frame delivery is fluctuating due to the real-time processing demands of RIFE,VRR mode of the tv will simply reflect that fluctuation by changing its refresh rate the best it can

And with maximum refresh-rate + madVR SM, result is not OK for you ?

No, its not.

I've tried interpolation from TV, it's OK, but in the end, you're changing some parts.

Interpolation on a TV is done by simpler means and the result is much more questionable. The changing part don't butters me. except when it highlights flaws in actors or changes in stunt doubles or even the distance of a punch

Tom Cruise endorse his director and that idea gain popularity because who he is.This led to more people engaging directly with the issue and becoming advocates themselves. No me thought I move beyond the mission. im free.

Filmmakers use 24fps for a combination of historical legacy, aesthetic effect, and practical production considerations. Audiences have been conditioned by a century of cinema.Hides cheap effects,Masks limitations in production design,Smoothes out makeup and costumes. Psychological distance meaning helps the brain overlook minor inconsistencies or flaws.
VRR seems to be the topic of choice at the moment, but to annoy everybody, I'm gonna harp about ACM some more.

Dont worry about it , its not the topic of choice , its only to contradict my claims, I won't post for a while and this topic will be forget.

So I was right all along. Root cause is too heavy settings.
You can't just delay frames if processing takes too long. Or show them early. Each frame must be displayed at an exact predetermined moment. That is essential for correct and smooth playback.

Furthermore, VSync is essential for accurate and predictable timing. Without it there will be inaccuracies of up to a few milliseconds, which are more noticeable the higher the refreshrate gets.

For texture setting please stick to default auto8/10. FP16 only increases risk of problems, and I doubt you are capable or seeing any beneficial difference.

Don't call bingo if you don't have all the numbers, regardless what settings you use, this fluctuation are inherentes of that combination ,below the target also ahead the target, and can be reproduce at 2x,2.5x,3x.4x
but then the tv will react different.
Is not caused by settings that are too heavy.

What you say would apply if I told you : "the playbackI is choppy, full of stutters and judder." ahhh ok try to lowering the settings. Many years of madvr taught me that already.

I have mkv-files with AAC 5.1 audio. My AV-Receiver does not understand this. How would I have to setup MPC-BE to convert AAC 5.1 to AC3 5.1, so I can bit-stream it to the receiver via HDMI? AT the moment I only get Stereo...

Hi :)
I think it would be a good idea to increase the size of the list of the refresh rates. Since now 100 fps and 119.880 fps and 120 fps videos are more and more common. I can add it myself, but I think it should be there for all users.
I add 3 to the existing ones 100 Hz, 119 Hz and 120 Hz. I checked the size and made a test if the 11 display modes can be viewed without need for scrolling and it works.
https://drive.google.com/file/d/1gKDZT6geVS8ShJ3R9Afnxg4v2CgrQyMT/view?usp=sharing

[v0lt]

Since now 100 fps and 119.880 fps and 120 fps videos are more and more common.
Where is it common?
I've found several films that have increased their frame rate using algorithms. But it hasn't become popular, as there are SVP and other ways to do it at runtime.

[Klaus1189]

Not for films but for higher end cameras. For me it would be great.

Also only an increased size of display modes in options would help me. The addition of other display formats is not really necessary, I can do that. But at least to get all 11 to see without the need for scrolling :)
Please, I really beg for the increased size of display mode list :)

sorry for the fuzz

[huhn]

on pretty much all samsung TVs 23p is bugged and forces subsampling.

mpcVR has issues with 23hz at 119p for example i really need to make that bug report but it is very time consuming to do.

everything up to 240 should be support 240 is still rare and every over that is very rare but even PJ have 240 these days,

[v0lt]

Not for films but for higher end cameras.
Yes, I read that modern professional cameras have a high frame rate recording mode, but no one makes recordings of more than 60 fps publicly available.

[Klaus1189]

I have more and more of them. Also users with actioncams have high refresh rate files like 100/119.880/120 fps. Can you please increase the size of display modes for 11 different without the need for scrolling for me? It should work for 11, because I tried the size in the screeshot in my ealier post. It would help me :)

[v0lt]

I have more and more of them. Also users with actioncams have high refresh rate files like 100/119.880/120 fps.
I don't have any videos like that for testing. This is the first time I've heard of cameras recording at 100 fps.

Here is a short sample:

[huhn]

even without content at 100 or 120 HZ you are objectively better of with 120/100 support.

the commen refreshrates are 23p, 24p, 25p, 29p 30p, 50p 59p and 60p.

with 120 support you only need 119, 120 and 100 to do all making reseync much less necessary.

Yes, it works, finally I could test it today. I think it needs to be a tiny bit bigger, so number 11 is not cut off. I think it is possible. I am begging ;)

For this suggestion the drop downlist for monitor is still more than enough for monitor names and we have space for Default and 12 other display modes. Even one more as a spare place for future :)
I also tested to have higher than 125.999 Hz but it always reverts to 125.999. Now not an real issue, but perhaps this lock can be opened so in future higher refresh rates are possible in display modes.

Hello, I guess there are not a lof of users (including devs) with Radeon GPU, so I'll have to deal with strange behaviors. I'm with a Radeon 9060 XT. With below videos, when I try to seek, the video does not play anymore, it's like if it was paused (except it is not).
I don't know how to debug this.
I'm with Windows 11. I've tested latest build (portable, default folder settings + new folder), with mpcVR (latest build).
https://drive.google.com/drive/folders/1Pf54IJ1N5XH3gS74vchD4pF0JlFRVjzQ?usp=sharing

Seeking works with mpv in comparison (but I have judder).

[huhn]

all decoder have an issue with that video including hardware that includes nvidia cuvid.

so while i can not say for sure that it is the video it could also be audio stopping the video this file does something and it is not AMD to blame here which is kind of refreshing.

[LigH]

Does it possibly work better after remultiplexing (to MP4 or to MKV, possibly with different options to support proper seeking)?

[huhn]

just remuxed it to mkv again and not still breaks after one sec a seek isn't needed. tested only with avcodec.
i have not setup mp4 muxing.

[Klaus1189]

If user wants to add MPC-BE to Start of Windows 11 it is impossible, I mean it doesn't show up, because it is added but not shown. User can "remove" it after adding.
Reason for this are the files "70.png", "150.png" and especially "mpc-be64.VisualElementsManifest.xml" which work fine under Windows 10 for generating a big icon in "Start"
Maybe add a small jpg, that it gets added? I don't know.

[pirlouy]

You meant like this ? https://imgur.com/rlrBwz9

Sometimes icons are not added, you have to either kill startmenu process, or add another program from start Menu (and then remove it).

But maybe you have a different installation ? I use portable mode.

[Klaus1189]

Yes, you are right. Not caused by these files. I restartet and tried again, now it works. Windows 11 is a mess ...

[CruNcher]

just remuxed it to mkv again and not still breaks after one sec a seek isn't needed. tested only with avcodec.
i have not setup mp4 muxing.

Confirm it i looked through a lot of .mkv now and i yet couldn't find anything from the past 10 years reacting like that.

ah no wait play->seek->play

not play->stop->continue

so basically the playback needs to stop after seek than its the same issue

found something Mainconcept DivxHD not exactly the same behaviour and looks more like a keyframe thing it continues but takes a bit

ok found another one that one is funny seekbar doesn't move but video plays but audio fails after the seek, wouldn't categorize it as the same problem (symptoms)

under normal circumstances it would only stop if the file is corrupt and you try to seek over what it thinks is the real playback time and you seek into 0 data

ok here is 0 seek corrupt playback time

after 388 seek tests i get to this file in the database now and it stops, you would suspect 0 keyframes to seek but you can scrub through it

590 seek tests nothing comparable unique parser issue

Huhn i can not confirm that it brakes on playback only @ seek and no problems with VLC except that the scrubbing in those 10 minutes is much more efficient by default with MPC BE in every way shape or form

lets test that really strange .mkv (ahh ok makes slowly sense that was a live recording and the CPU couldn't keep audio video sync) the seekbar only moves when the audio gets sync not because the video is playing still weird.

but also VLC does this right now makes less sense why MPC BE is failing and stops waits continues.

(2) Built-in Video Codec/Transform
(3) Enhanced Video Renderer(Custom Present)
(4) Built-in Audio Codec/Transform
(5) DirectSound Audio Renderer

also scrubbing through at lightspeed

with the strange mkv that 1000 fps also potplayer has problems hitching with the audio but it doesn't stop

these guys from Kakao make not only good 3D Engines

yeah it uses the 1000 fps it tries but the audio forces it to back down

funny to watch

its scene browser creates 40 scene cuts for that 10 minutes of our open gop 0 problems jumping to any part while playback and no unexpected stops

and it has another advantage it doesn't failure in any fullscreen mode with strange slowdowns.

so many problems in MPC-BE with that as soon as you fullscreen stability goes down and you have to render something of the OSD on top in non exclusive mode that it doesn't slowdown (for me i have to least render the seekbar or the playback bar) not with potplayer doesn't care if it renders something of its gui or not it stays the same.

Just a amazing piece of software stability work.

Not sure what the Koreans do better but they do it better.

and they seek without problems through the bitstream .264 forget that with lav filter or MPC-BE raw source neither works in MPC-HC lav filter internal combination

The Overall Windows Integration of Potplayer is more stable in every way the entire Framework.

MPC-BE

lets remove that seekbar

(WOWY)

Where are those 30 FPS gone to ?
What for a rocket start was this ?
30 FPS got just Decimated by a few more pixels (hallelujah) ?
What just happened after CTRL+1 ?

https://iili.io/fCB2y4S.md.jpg

Process Priority is Higher than Normal and its on Top but it still slows down why ?
The Input latency it stalls like it's not reacting anymore

https://iili.io/fCOdtEl.md.jpg


That explains it V-Sync disabled by default ?

https://iili.io/fCkWct2.md.jpg

Ok 1 Problem fixed Parser seek Problem still alive

https://iili.io/fCvAnmg.jpg

@pirlouy you don't need any sync test patterns for MPC-HC(BE) the Tearing Scanner Bar has the same function if its broken Sync is broken and it is overall more efficient than any counter value you can read out of the system.

CTRL+T

What you want to achieve the bar stays stable from the beginning or recovers into a stable state in as few scan cycles as possible and never gets unstable after the recover for the longest time possible at best with no matter what is running in the background.

If its the nice firefox or chrome at best you would want to melt them all together so the problem doesn't exist anymore.

Google would have the Power to make a end to this.

PS: It also shows no seek stop problems in MPC-HC (Lav Filter Internal) but scrubbing has higher latency than Potplayer/MPC-BE

But the Fullscreen results that is stable and it doesn't twitch it stays stable

https://iili.io/fCQQEoN.jpg
https://iili.io/fCZuoox.jpg


The Additional Performance Counters in the OSD from MPC-BE also cause overhead better not read and print them from NvAPI for sole playback stability purpose, rule of thumb if you don't need it don't read and print(write) it.

https://iili.io/fCDnVHu.jpg
https://iili.io/fCDifkJ.jpg


https://iili.io/fCDGR5J.jpg


Yeah missing sync features outside of DWM make MPC-BE weaker than MPC-HC but also Potplayer doesn't do so well outside of DWM

MPC-BE + MPC Video Renderer that can change something, nope no mode as stable as the MPC-HC result over a long runtime even after 3 cycles it gets unstable and brakes apart.

https://iili.io/fnKoJI4.jpg
https://iili.io/fnfqQP1.jpg
https://iili.io/fnqCMDx.jpg
https://iili.io/fnqlGOQ.jpg

No chance with MPC-BE can't get most of the Sync with it stable for more than a few cycle before it brakes.


Efficiently Destroyed

https://iili.io/fnBFEas.jpg


Only the old MPC-HC with lav internal shows really awesome stability results for now in every sync case, its also forces to resync which most of the times fails completely with Potplayer and MPC-BE

Sometimes the old things have still value

MPC Video Renderer needs exclusive switching to keep the Performance of EVR ?
Where EVR goes without Problems directly into Fullscreen Performance without needing Exclusive Mode ?

You lose all interfacing with Windows to keep the Performance of EVR ?

[v0lt]

All discussions about performance are meaningless until the testers provide:
1. The video files being tested (without this, everything else is meaningless). :D
2. A description of the hardware used for testing: CPU, GPU, RAM (is dual-channel mode used?) What is the full-screen resolution?
3. Windows version, player version, decoder version, video renderer version?
4. Settings other than default.
5. The method used to measure performance. :rolleyes:

[CruNcher]

The method used to measure was my eyes mainly because im not sure i can trust any counters anymore

The hardware is obvious the OS is Obvious the Resolution is Obvious and you supply no own Performance test data at all and the maximum capabilities of your Render approach

so what i see for now you can do up to 2160p 32 fps in this while EVR can do a at least a maximum of 2160p 60 fps without to discard anything and without Exclusive switching

And this is what i measure on

Zen 2 (8 Core 3700x)
Geforce RTX 3070 (GA104/VP11)
Windows 7

And the result are constant for now in MPC-HC/MPC-BE and Potplayer using MPC Video Renderer with each Parser Decoder Framework no matter the input and the settings play no real role this seems to be a strange hard limit or a very crazy bug for your Renderer outside of Exclusive Mode

These results are constant between EVR and MPC Video Renderer in non Exclusive Fullscreen on this HEVC VP11 2160p 60 tests MPC Video Renderer DXVA2 can not beat EVR but loses 50% Performance and you realize it in the Motion Difference and yes in Exclusive it can do the same 60 fps but outside no chance to beat EVR that can achieve it without Problems not depending on Exclusive Mode

With your default setup and some extra tweaking maybe the absolute maximum currently is 32 FPS

Ok i reject in MPC-BE as complete framework you can get the 60 FPS when the seekbar gets displayed so you need to draw some gui element and resize the surface (looks like just a very minimal render surface deviation) to reach the 60 FPS of EVR so crazy what is going on ?

Crazy to Grasp and understand it this behaviour its so fucking strange between MPCVR and EVR

https://iili.io/fIXjm4n.th.jpg (https://freeimage.host/i/fIXjm4n)

With the Seekbar you can keep the 50% Performance ????

v0lt/Aleksoid please help to understand this, it turns me upside down i just want to understand this strange 50% loss of Performance i start to trust no counters anymore (overall my believe in counters is low, but not my perception of motion impact).

I want to solve this with you together.

[huhn]

here it is doing 8k to 4K 60 HZ with the most inefficient settings available...

https://i.ibb.co/kLFp1xp/image.png

looks like it can do 60 FPS.

a small hint the decoder is giving the video renderer 31 not the video renderer is doing 31.

so best guess D3D11 video renderer is feed with DXVA2 (D3D9) forcing an interop.

[clsid]

The Present time in the stats is super high. Even in windowed mode. Here it is 1ms or less.
Try swap effect discard instead of flip.

[CruNcher]

ok it gets clear now Direx3D 9Ex versus Direct3D 11 @ Huhn this was running in Direct3D 9Ex by default

Direct3D 11 becomes the only option to keep the same performance as EVR ok

thats 100% established now in this configuration

that makes every other sync option unusable and this is a clean broadcast with 0 sync problems or sync complexity and it allready tears

so to reach the same Performace Direct3D 11 is practically mandatory with MPCVR we have no other option the only path

https://iili.io/fIweEzb.th.jpg (https://freeimage.host/i/fIweEzb)

https://iili.io/fINc9It.th.jpg (https://freeimage.host/i/fINc9It)

[clsid]

That is nonsense. D3D11 is not the preferred method on Win7 and has severly limited capabilities there. As a side-effect hardware decoding is now disabled and also the video processor. Both of which you could also disable with D3D9 if you want to test that. But first try changing swap mode!

The problems are specific to your system, and not a general issue that applies to everyone.

[CruNcher]

Yeah that hardware decoding is disabled i can partly hear now
so ok Direct3D 11 is the wrong path in this case so disabling it again but swap mode change does have no real effect flipex or discard tested this so often in the sync tests on this performance gap and loss but on the sync it partly has

The Performance loss is a complete isolated issue from the Sync (i think, can you ever be sure of anything) and it doesn't exist with EVR

https://iili.io/fIOuZcN.th.jpg (https://freeimage.host/i/fIOuZcN)

How to find a explanation for that now, what stalls it from reaching 60 fps and almost exactly 50% *poof* gone they left the stage ?

Ok maybe im as far todo a driver reset but i would just hope the 50% come back maybe they do but i have doubts it will change anything.

Or maybe i gonna try a weird bios experiment first but i have absolutely no idea why EVR should not be impacted and MPCVR is which makes also 0 sense.

EVR is not broken MPCVR seems broken ?

EVR uses some MAGIC MICROSOFT HIDDEN TRICK or Nvidia optimized it internally going its fastest path ?

[huhn]

win 7 with disabled desktop composition.
no one should fix anything related to that anymore more because it is "impossible" to do that on win 8 and newer.

this is still a guess but it explains why FSE would work and why windowed doesn't. enable aero and windowed application may sync correctly because that's a major job a of aero.

d3d9 still works just fine it just so old and outdated that it can not do some stuff or a lot these days. AV1 can not be decoded by it and to be utterly honest the DXVA2 native path is broken by design.

[CruNcher]

EVR shows so many differences in that regards it seems like BLACK MAGIC of the Past

https://iili.io/fIvXLVj.th.jpg (https://freeimage.host/i/fIvXLVj)

no tearing no problems hardware everything

https://iili.io/fIvmNYQ.th.jpg (https://freeimage.host/i/fIvmNYQ)

EVR Sync Render does the same shit and tries to go to 30 fps in Fullscreen in Windowed it stays stable

Present at nearest Vsync and it tries 30 fps 29.96 when you leave the nearest Vsync out

it looks hardcoded (do not allow 60 fps maximum 30 but do not allow 60 fps Fullscreen discard discard discard 60 FPS Fullscreen IS EVR ONLY TERETORY) or like EVR runs hidden in Direct3D 11


Windowed we give it to you for FREE but Fullscreen contact us ;)

But who to call i haven't the right number yet.

Ok someone thinks hes clever here how about almost fullscreen mode take that (hahhh ;))

https://iili.io/fI4PryN.th.jpg (https://freeimage.host/i/fI4PryN)

so all benchmarks can only be conducted in almost fullscreen mode and windowed GUI mode


The impact here is really the bottom last horizontal line you can see how DXVA2 switches OFF/ON when resizing the window from the bottom (seek/playback bar)

the 30 fps impact is hardware function loss in Fullscreen DXVA2 brakes but it seems to brake on the Render side not the Decoder side

there is a specific surface performance impact as well in terms of the resolution even if it shows DXVA2 doesn't mean full Performance will be reached at a certain resolution there will be still Performance fluctuations until a certain resolution is reached.

interesting stuff

https://iili.io/fI6vgrN.th.jpg (https://freeimage.host/i/fI6vgrN)
https://iili.io/fI6rfN1.th.jpg (https://freeimage.host/i/fI6rfN1)


One of the most sane things to continue is to test further renderer like madvr and halls behaviour if they are not coherent we will see EVR doesn't show this problems we know for sure that DXVA2 doesn't brake in Fullscreen with EVR.

So we already see the problem on the Render side and with a pretty high probability a failing calculation inside the Renderer.

We will find and eliminate this one way or the other.





https://iili.io/fIPL6t2.jpg

[CruNcher]

So MadVR also fails but can't dynamically update it's DXVA2 state like MPCVR can

So MADVRs OSD is blind when it loses DXVA2 its static it thinks it's still there to be exact we losing DXVA2 Scaling in the Renderer oh sorry my fault it understands it only not DXVA2 scaling is not on by default like in MPCVR but MADVR understand when it lost it also instantly

https://iili.io/fIQr7G1.th.jpg (https://freeimage.host/i/fIQr7G1)
https://iili.io/fIQPFQp.th.jpg (https://freeimage.host/i/fIQPFQp)

so the setup when it stabilizes in MADVRs default setup with DXVA scaling but Sync is not as efficient as with Default MPCVR setup it tears compared to it stabilized

https://iili.io/fIZdnFs.th.jpg (https://freeimage.host/i/fIZdnFs)

stabilized that setup has 0 chance vs MPCVR on the tearing side of things, the tearing is a catastrophe compared to MPCVR in that setup

Yes got it much better in direction of MPCVR tearing results which is practically 0 tearing in this test case

but makes no sense MPCVR is so good optimized waste of time

140 skips the lowest i got out of Madvr was round about 250 but the motion stability difference worlds apart

and in the 2nd run its like in the 60 skip range with OSD boah impressive yeah it stabilizes after the 2nd run into the 60 skip range on FlipEx

3-4x more efficient than MADVR somewhere in the base performance and that is visible in the motion result

Discard= ~130 skips
FlipEX= ~60 skips (the question how many from the counter and the Graph ?)

https://iili.io/fImmF1e.th.jpg (https://freeimage.host/i/fImmF1e)

EVR Full OSD Load = ~ 2 skips (its correct the OSD filename overlay at the start 2 skips)

https://iili.io/fIpFBY7.th.jpg (https://freeimage.host/i/fIpFBY7)

The Answer to the MPCVR counter Graph question above

~ 34 skips

https://iili.io/fIpiAWg.th.jpg (https://freeimage.host/i/fIpiAWg)

[huhn]

the present times are in the 30 ms range not in the 0.0X ms range.
that's because there is no composition been done because aero is off making it a gamble to work.

DXVA2 everything except copyback decode is fundamentally broken with nvidia.

just as said before but whatever i'm done here.

[CruNcher]

Yes i gambled it out on MADVR but it was very obvious that the default setup is outdated

i have a new setup with a stable present time of comparable present time with MPCVR but the Motion stability result is far away from it

and MPCVR comes really close to EVR custom will it ever reach it most probably not

that DXVA2 is broken on Nvidia yeah i slowly guess too not for nothing they did their own APis

Maybe Cyberlinks Renderer can beat it but i doubt neither them beat EVR

at this surface setup it skips almost nothing anymore in MPC-HC Lav Framework

https://iili.io/fT2zuS9.th.jpg (https://freeimage.host/i/fT2zuS9)
https://iili.io/fT2SPig.th.jpg (https://freeimage.host/i/fT2SPig)

That gets pretty close to EVR Custom now

MPC-HC Lav Framework + MPC Video Decoder shows higher stability at a larger surface compared to MPC-BE and it's Framework in this test

now MPC-HC Lav Framework will meet Potplayer

But to set potplayer up with this overload of options is a first learning adventure in itself to find yourself around nothing for a avg user
Nothing for the Faint hearted and especially not if functions not available for certain renderer do not get discarded out of the Gui and setup options dynamically (major design flaw of this whole Player it does it partly but it should discard the overhead completely)

But overall its a wonderful redesigned and architected MPC-HC Core and it shows you the bitrate right in its OSD ;)

MPC-HC Lav Framework + MPC Video Renderer clear stability advantage on the overall overhead side

And super easy switching between all important Renderer configurations 2 to be exact rest useless

Only a Vulkan one missing now and AI

the 30 FPS test pattern surprisingly hard to crunch for MP-BE + MPC Video Decoder

i want to keep only those test patterns that fail in every framework with MPC Video Decoder

but these test patterns they are no hardcore tests at all compared to a real test stream

yes he developed the Task Manager for Windows (Windows 7 251KB) inspired by top as a important component but more important he developed HyperCache (AMIGA) which transformed into smartdrv.exe (MS-DOS) what resulted later into Windows Prefetch and SuperFetch :)

I cant believe what i see.

this is not the same render mode either do you realize something ?

The Render System Power Consumption is the same (calibrated with OSD complexity)

PS: Resizing in a specific Bios setup can crash the Kernel when the FPS switches drops without warning to 30 instantly

https://iili.io/fuXYSsa.th.jpg (https://freeimage.host/i/fuXYSsa)

that wont be easy IRQL_NOT_LESS_OR_EQUAL

seems moving from the default XMP Profile to Auto caused it

Also MPC-HC + Lav framework + MPC Video Renderer and MPC-BE + MPC Framework and MPC Video Renderer work differently with the DXVA2 state display it looks like only MPC Framework can show this state information with MPC Video Renderer

Yep it seems Lav Framework cant update the MPC Video Renderer OSD Surface Scaling information it seems to make MPC Video Renderer less dynamic in terms of correct input system state analyze i think i got them pretty sync now and they show these differences now more clear and overall not really surprising that the message communication of states in realtime is a key thing for MPC-BE to track with MPC Video Renderer all the time so the Renderer can react on every possible input/system chain change as fast and fluid as possible if necessary From the Parser through the Decoders up to the Renderer (one symbiotic ecosystem that is your goal a clear and efficient realtime message state communication) at best you even have the Driver,Kernel and Bios under your control.

So everything works full automatic in its decision chain and when necessary you can still override it's decision.

But the real goal is to become both 0 skip state sync first

Another difference you will find is the quality display of MPC-BE + MPC Video Renderer and the Playlist update and how the Quality display reacts

You can freeze the output in MPC-HC Lav Framework + MPC Video Renderer wont happen in MPC-BEs entire Framework it will just kill the quality display (its own configuration display) instead of freezing the output on the playlist change

small differences but well thought of in the way each component communicating with each other to avoid problems (that makes the difference from a good player to a fantastic player) but to see this you have to dig deep.

No wait DXVA2 state is dependent if you touch the window from the inside or outside and also MPC-HC lav Framework understands this the same way.

Sometimes the update freezes in MPC-BE and MPC-HC Lav Framework shows the Driver but MPC-.BE doesn't its the same renderer version ?

ok it shows the same render version number but it isn't the same ohhhh man

ok new try lets go with the latest nightly build and update MPC-BE as well i was to slow and seems i compared wrong in term of version releases even if the version number didn't change seems like internal was outdated and i ran out of sync on the render version side

so the driver version addition if i see it right comes from clsid and he executes his own renderer version directly from the main directory (should have expected that) so just delete or rename his version and you sync

So there is still the 50% Performance loss vs EVR custom in Fullscreen Windowed in the newest nightly on this system configuration

All Sync Now


Man this new MPC-BE behaves strange cant pin it to the taskbar, jesus what is this now right click context menu doesn't function ?
MPC-HC no problems pinning it

This is the Problem in MPC-HC Framework when the MPC Video Renderer properties window is open and it reloops or switches on the playlist but it detects it also (didn't do the exact same thing when it loaded its version but actually tried to continue which failed in a black screen as long as the properties window is open) only MPC-BE goes another approach (path) shortly before this actually happens it will kill (destroy) the properties window and keep the MPC Video renderer and its output alive or it reinitialized the graph different didn't look in the code but it will do it more efficient and not get stuck.

So in MPC-BE you wont see this message at all.

https://iili.io/fu8oa7R.th.jpg (https://freeimage.host/i/fu8oa7R)


MPC-BE on ther other side handles its entire windowed different not really more efficient than MPC-HC keeping 0 space to the Desktop actually 1 line on the right, but therefore you can access the taskbar when its on automatic hide/show which is not possible with MPC-HC you have to call it explicit with the WIN key but overall its the better way as you can get the entire Desktoip space for rendering which MPC-Be seems to cant get entirely when manually resizing.

So MPC-HC is infront of the Taskbar and so the tasbar can also not adapt its window like by design it normally would show it and resize the aside application space but that neither works in MPC-BE there it will get infront of the render surface and hide parts of the video behind it and not adapt MPC-BE its window

actually you can get MPC-BE window to behave correct but it's tricky and not functioning entirely like it should

but this details are unimportant i will sync both to MPC-HC way of handling it everyone has his own ideas of how to handle windows and when you look into Windows 8-11 space then your ideas become different

but in terms of the pinning interop that seems totally broken in the current nightly of MPC-BE

Reached the first 0 skip loop setup for MPC-BE for both test cases firefox in background open low load

https://iili.io/fu429Gs.th.jpg (https://freeimage.host/i/fu429Gs)

closing firefox see ya...

2nd 0 skip loop peak is testcase switch (No firefox) ontop System counter load

https://iili.io/fu6MyAb.th.jpg (https://freeimage.host/i/fu6MyAb)

We run through it at high speed not EVR but anyway

https://iili.io/fuPqQ9a.th.jpg (https://freeimage.host/i/fuPqQ9a)

In this configuration this 2 skips are optimal as they come from the file OSD display overlay at the switch start (this is optimum for non DWM)

If you compare this for example with the Resident Evil Benchmark this would mean A score and yeah sometimes these 2 also do not happen but that's uncertainty and needs to be checked better with your eyes at that moment but it might be even correct as this is a internal OSD process not coming externally like a Windows Notification and if you sane with transparency and at the same time you balanced additionally the timer interrupts and overload you could get good results even in relative complex situations.

https://iili.io/fuPaDDN.th.jpg (https://freeimage.host/i/fuPaDDN)

But i hear currently that peak and that's a complete no go and i still have to balance out

https://iili.io/fuihcbe.th.jpg (https://freeimage.host/i/fuihcbe)

You know what that 1 skip was not the peak,that was the push of the print button (pushed captured)

https://iili.io/fusOe5l.th.jpg (https://freeimage.host/i/fusOe5l)

This is even much better (print button pushed 0 captured 1 appeared) you captured the print button push before it updated the value you copied the render surface instantly with absolute low input latency from a wireless keyboard

https://iili.io/fuLFa5u.th.jpg (https://freeimage.host/i/fuLFa5u)

and guess what i have a wireless keyboard currently the input latency is ehh not far from EVR only EVR Customs Graph can capture the print button interrupt fluctuation as well instantly, so if you push it you will see a super fast peak in EVR Customs Graph running by

MPC Video Renderer Graph runs in a much saner timer update mode speed than EVR Custom Graph runs in it wont capture it but its frame skip timer update speed is high enough to capture it

[CruNcher]

https://iili.io/fuLgaiN.th.jpg (https://freeimage.host/i/fuLgaiN)

So this starts to become harder inside the loop on stability here it starts to skip but with a fresh and only the 60p int as main benchmark it still works in the low skip area but the stress becomes higher still doesn't make sense that we endup here at 30 fps at the end of the resize and EVR Custom doesn't

and at the last line it doesn't matter anymore if you touch it from the inside or outside or stretch it it wont reach EVR Custom Performance and keep the Full Motion Result alive its going to instantly Half the Motion Output Result reaching the last line with 1000x of skips.

Forced on the Driver or on the Kernel level but we can still finetune the skips at the edge and than find the reason

Anyone have this problem?

1. Launch HDR video.
2. Windows 11 switches to HDR mode.
3. White levels and highlights are blown out.
4. Close MPC-BE, switching Windows 11 back to SDR mode.

I can confirm that this happens sometimes. I can't pinpoint the cause; perhaps there's a bug in the HDR API or something missing, but since the API isn't documented, there's nothing I can do.

[CruNcher]

Aleksoid1978 could you take a look into the taskbar pinning problem ànd why the interop with Windows 7 broke in the nightly of MPC-BE and you cant get to the right click context menu for it anymore to pin it and create the .lnk ?

Close window/pinning all functions lost
you get straight to the taskbar playback right clicking on its icon

or lets test how fast mpc-be and hc gonna detect the dat as wrong

lets see what happens when we put them in the playlist :D

not a bad job some false detections playbacks based on header assumptions but no crash yet

with 2 cores it parses through and denies a lot in that list as not renderable (invalid) that pretty fast but these are kb data with random header in between it crunches through now

now it reached a drive it has to wake up (no crash calling it out of the bed) mpc-be waited bravely ;)

it also knows nicely what it checked and opened already and continues from there

i love how it does it awesome and fast

Close and it continues its work oh yes baby you have a mission to complete (my evil performance and stability tests) :)

this test stresses the gpu as well because of the fast OSD response it has to achieve (its like it opens and closes it pretty fast intense OSD overlay render work the more efficient you are here the less skips you will encounter)

https://iili.io/fAGOyXt.th.jpg (https://freeimage.host/i/fAGOyXt)


though this is the combined parsing and render test so its gonna be forced to stop and also make decisions of its own and with the OS together and it does pretty good so far.


that is really interesting

That sounds crazy

matplotlib\mpl-data\sample_data\membrane.dat

some playback hits come also through weird lav splitter and mpc connections (this here is not anymore strictly limited to the mpc-be framework but entire registered directshow chain)

and the dshow lav splitter side was not updated for a longer time could come together all at once here

but as long its not crashing let it go in some cases of playback success on the wild side of the test even Mediainfo does agree and sometimes not but mpc-be currently helps to create a in the wild test list of this looking a bit closer

ok now it hangs but was my fault i tried to force it back while MPC Video Renderer was running to another file and that pretty fast while it switched to another already going through images and that speed of redirection was a bit to fast and most probably just in the wrong moment and the result (AppHangB1).

but the good news it saved the last playlist state nothing lost :) (we continuously edited in the playlist) and then we provocated the AppHangB1 (high graph render switch speed redirection and that was it, the situation is like you driving with 300 mph and pull the handbrake).



Chatgpt 5 explains the situation


Driving 300 mph (≈480 km/h) on a public street is already far beyond what any normal car — or human — can physically handle. Pulling the handbrake at that speed would not behave like a dramatic stunt; it would almost certainly be instantly catastrophic.

Here’s what would generally happen, without giving instructions on how to attempt it (please don’t):

�� 1. Instant loss of traction

A handbrake locks (or strongly slows) the rear wheels only.
At 300 mph, the rear wheels losing traction would cause them to slide, while the front wheels still try to roll forward.

This makes the car behave like a shopping cart with the rear wheels welded — the back will swing violently sideways.

�� 2. Immediate spin-out

Instead of a controlled deceleration, you’d get:

Rapid oversteer

Instantaneous yaw (spinning like a top)

Zero ability to counter-steer at such speeds

The car could start rotating at hundreds of degrees per second.

�� 3. Structural failure

Most cars begin to physically tear apart long before 300 mph due to:

Aerodynamic lift

Tire integrity limits (most road tires shred near 180–200 mph)

Chassis forces far above design limits

Adding a high-speed spin would likely cause panels, wheels, or suspension components to break off.

�� 4. Catastrophic crash

You’d likely:

Roll over repeatedly

Leave the roadway

Experience forces incompatible with survival

Even professional land-speed vehicles on salt flats — perfectly straight, empty, controlled environments — face lethal risk when something destabilizes them at speeds far below this.

�� In short

At 300 mph, pulling the handbrake would result in instant uncontrollable spin and near-certain destruction, not a cool drift.

Almost guaranteed:

rear-wheel lock → sudden spin

Highly likely once spinning begins:

aerodynamic lift

rollover

airborne trajectory

complete vehicle breakup

Whether it flips before or after leaving the road depends on tiny differences in angle, wind, or surface — but either way, the result is catastrophic.



Let AI explain to us how it compares



It can be comparable in the sense of how a system reacts to a sudden, disruptive command while it is already processing something at high speed — but the outcomes are obviously very different.

Here’s the clean analogy:

��️ DirectShow pipeline ≈ A car driving fast

A DirectShow filter graph is like a vehicle in motion:

It processes data in a continuous stream (frames, samples, etc.)

Each filter expects data in a certain order and timing

Interrupting it abruptly can destabilize the pipeline

��️ Switching the input mid-stream ≈ Pulling the handbrake

If you are:

Walking the graph through files

Reading headers or frames

Feeding images to downstream filters

Then suddenly tell the graph to load a completely different image from another source, without resetting the graph state

…this is like yanking the handbrake:

The pipeline can:

stall

break the connection between filters

throw timing errors

cause a format negotiation failure

crash the graph

deliver corrupted frames

DirectShow expects steady, well-structured samples. A sudden change in media type or source breaks that expectation.

�� Why it behaves like a “high-speed spin-out”

When a DirectShow pipeline runs:

Upstream filters push samples

Downstream filters expect them to match the negotiated format

The graph manager manages timing and allocation

If you abruptly swap the image source:

You create:

media type mismatch (e.g., resolution, pixel format)

unexpected timestamp jumps

buffer length inconsistencies

allocator mismatches

null or invalid pointers

Any of those can “destabilize” the graph — similar to destabilizing a car at high speed.


ouch maybe we better leave lav splitter enabled when reaching certain files especially those Mediainfo agrees with

the dummy files lav splitter fails on trying to playback mpc-be splitter ignores them but this it keeps stable playbacking without crashing but it seems certainly not spec in some way and that MPC-BE crashes on something specific purpose designed is maybe better than playing stable half garbage

without lav splitter as support it super fast crashes on many unexpected streams

but the major difference is really the dummy handling lav splitter takes all of them mpc-be ignores all of them and mediainfo doesn't understand the dummies either as anything usable to even try to playback

and mpc-be is fully right better don't open them

[huhn]

really not important:

i got freesync working by accident...
i had an old copy of mpc_hc that i renamed and today i got a bit farther... i resource hacked it to be not mpc-hc and freesync is kinda working now. it also has an old test build of mpcVR for freesync in there i was just testing nvidia smooth motion (pffff just right AI on stuff...).

if the frame times would be smooth the result would be fine.

i have smooth motion running on a 23p file and the present times are ~21 which sounds about right but dipping to 14ms and up to 26 ms making issues.

here is a screenshoot: https://i.ibb.co/Ps22yQGS/image.png


i can share my "hacked" mpc-hc version and the nvidia inspector settings if you want to waste more time on that.

[huhn]

real bug report.

this is about the frame time issue i'm talking about for like a year now.

i miss matches the refreshrate here 24p int video screen at 120/1.001

so audio video will run async and the video renderer has to repeat drop frames to stay in sync.

all of this is normal but not working correctly. but here comes the issue mpcVR starts to correct sync after reaching 4ms of desync which is half a vsync interval but it is now switching between the old sync and the new sync for the next 1-2 sec like 12 times it doesn't stay at one sync.

also the time should change by about 8 ms. if you drop or repeat a vsync a ~120 hz the is no other possible results but it is 4 ms.


i have a lossless video recording of this:
https://drive.google.com/file/d/1B_tHq9NCwG0v8j1ct0pjGJidNl-WVJuX/view?usp=sharing

it does a 4:6 pattern(literally the same as 24p played on a 60 hz screen) in stead of 5:5 with one drop/repeated vsync.


the one big skip in rtss and the blackscreen with it is just an artefact from going fullscreen and can be ignored.

the frame rate mismatch has been choicen because without it it can take up to hours and in most cases minutes and i have something better to do then record for that long and look at the screen.
this setup is still not rare.

[v0lt]

real bug report.
1. Real (actual) bugs must be reproduced in the current release or a recent beta version.
2. Don't use the "Wait for V-Blank before Presentation" setting for high-refresh-rate displays. It's better to enable the "Adjust the frame presentation time" setting.

[huhn]

1. 0.9.19.2490 has 100% the same issue.
2. this breaks it pretty much entirely and it is doing 6:4 all the time. at least in the recording because the frametimes are bad. wait for vblank works perfectly as long as the frame rate is perfectly matched. or let me say it differently can work properly we still have the problem of windows here.

[clsid]

24.000 at 119.880 means each frame should be shown on avg 4.995 times. Or in ideal situation 199x5+1x4 each 200 frames.

Currently it presents frame half a sync duration in advance of the ideal display time. That is in your situation 4ms (and in practice that might be 3ms).
To get a 6:4 pattern it must mean that the present finishes processing just before/after the VSync moment. The ones that are a fraction too late will only get shown 4x, next one 6x.

Wait for VBlank should theoretically avoid that issue. But apparently presenting a few ms in advance is not soon enough?

But I think an improvement is possible for "Adjust the frame presentation time" in case "Wait for VBlank" is enabled as well.
Since it knows a VBlank just happened, renderer can calculate time of next one.
If display time of current frame is before next VBlank, it can present immediately, without sleeping for half a sync.
If it needs to wait for more than a sync interval, then it can sleep until a moment than equals a future Vblank + 1ms.

[clsid]

@huhn
Try if this experimental test build (https://www.sendspace.com/file/gsqzhd) gives any improvement.

[huhn]

for best result mpcVR should present a frame for every vsync.

so currently windows gets 24 frames and has to deal with that and as you can see it is really bad at doing so...

the one thing i do not understand is how can it go from -4 ms to 0 ms that is not possible it should be at ~+4 ms a vsync is over 8ms.

the big issue in the room here is even with matched frame rates it should have the same issue shouldn't it it? just takes between 40 mins to days to happen wouldn't it?

i will test that build now it will take a bit.

[huhn]

@huhn
Try if this experimental test build (https://www.sendspace.com/file/gsqzhd) gives any improvement.

it made it worse the interval is now halved but that's also a very good news what ever you did had an major effect.
https://ibb.co/xS59yPzv

[clsid]

Do you see an actual visual difference with all those graphs and overlays hidden?
How is it worse?

Also, be aware that you need to interpret all values and graphs correctly. If rtss hooks into the present call, then it measures the rate at which frames get presented which has slight variation compared to the constant refresh rate at which the frames end up being shown.

Presenting a few ms in advance does not mean it is out of sync.

it is visible frames are not shown with the correct cadancy. the rtss reported frames rates which are far to slow shown are still over +-5 ms difference which will result in a frame drop/repeate. maybe i can get an better rtss overlay show the frame times if it is over 8 ms there is no doubt. i can see the issue so...

madVR calculates a frame drop every 42 sec (audio sync seems to be pretty spot on with that refreshrate soundcard combo). with a vsync drop we should get a 4:5 cadancy every 8.4 sec and look at the old version it does it every ~9 but 6:4 for a while not just one frame.

the thing that is different brtween these version is that the time between hickups is the same but the hickup duration is much much longer and the is a break between 2 major hickups durations where the frame tiems are bad but not so bad they should eb visibility all the time.

BTW. i found this issue not by looking at graph but by looking at the image. they are for debugging.

already set.

[clsid]

Another test build (https://www.sendspace.com/file/xobn33)

This one does not wait for vblank when frametime is less than a sync interval in advance.
And when longer it does a loop of vblank waits instead of a sleep.

Edit: new build, which also increments failed counter when vblank takes longer than 1.5 times the vsync internal.

[huhn]

the fail counter never rises issue is unchanged the pattern looks like the live version.

windows DWM issues?
there are even 7;4 in the recordings i set rtss to 5 ms and not i know the frame timing are for example 46.7 35.6 47.6 41.8 41.5 35.6 47.7 35.9

there are 12 ms jumps the result can only be bad.

and just to be absolute clear we are not talking past each other missing a setting:
i test with "wait for vsync before vblank" and "adjust time the frame time presentation" in the past.

"wait for vsync before vblank" 24p source and 120hz refershrate is utter perfect BTW and then it falls totally apart:

"wait for vsync before vblank" can be disabled and the graph looks a bit better but the result ins bad.

newer test are now without "adjust time the frame time presentation"
this option results in longer hickups.

Is there a way to increase the font size of the status bar (including the height of the status bar) i.e the video timecode in the bottom right and the paused/play in the bottom left, i couldn't find an option?

Is there a way to disable the grey gradient of the controls bar and status bar to make them solid black or solid grey? The controls bar would look something like this:

https://i.ibb.co/NgZwF74B/mpc-be2.png

I changed the rounded corners for the [GPU] and play button in my modified screenshot as i think square corners look much better. It would be nice if there was a setting to make all corners square.

I also made the text white instead of grey which also looks better, not sure if there is a setting to do that already?

How weird is it that I finally got 23.976 working by having both Wait VBlank and Adjust the frame on at the same time? I'm using the MPC-HC automatic full screen modes and also have VSync forced on in NVidia CP (stutters like hell without it regardless of other settings). Even this combination didn't work with 806; like other solutions tried, it worked for a very short while, then started stuttering after some 300+ frames in. Eventually it got to the point where the TV started to lose connection every time when going full screen with 23.976 videos and I just had to give up and relegate them back to 24 fps mode. But with my new 810, the aforementioned solution seems to work perfectly...

[kirakami]

Nvidia has broken something so badly that 23.976 fps videos don't play properly on any player if you have g-sync monitor. All 23.976 fps videos cause micro-stutters and panning shot judders and if you enable 1% lows in nvidia overlay, you can see the 1% lows fluctuating around 19-21 fps. The only workaround is to enable motion interpolation like nvidia smooth motion or hopperrender which fixes micro-stutters and panning shot judders but has its own set of issues since it is interpolating frames which inevitably cause scene-change artifacts or image distortion in videos. 29.97 fps and 60 fps videos don't cause micro-stutters but can still cause panning shot judders.

VSync MUST be enabled in the player profile, and GSync MUST be disabled in the player profile. VRR is not supported.

Is Mpc-Hc / Be with madVR 0.92.17 / Test Build 208 able to use dynamic metadata for DV profiles? Or is (the horrible UX and UI), Energy Media Player the only real alternative for that? That would be a shame because mpv, Mpc-Hc / Be is such great players overall.

[clsid]

madVR does not support DV. You need to use MPCVR for DV (which converts it into HDR).

Thanks buddy, yeah long time user of MPC VR, it's awesome, just wondered if there where another option for using the dynamic metadata of DV. I assume converting to HDR exclude the dynamic metadata similar to mpv that converts DV to HDR10.

[clsid]

Both support dynamic metadata.

[KrazyLurt]

Both support dynamic metadata.
Thanks! Maybe I used the incorrect terminology and should have wrote the DV RPU. Because for example this test file
Dolby Vision Lake Dynamic Changes Test (Profile 8.1) 23.976fps
https://drive.google.com/file/d/1-8C0ZYnIhEqOVJQ532hIJobP5XR6A7gj/view
results in visual differences in contrast, saturation and such with Energy Media Player. It does not with mpv or MPC-HC with MPCVR.

[Amuat]

Damn you kirakami, you jinxed it! No but seriously, worked for several days, then just suddenly... didn't (I have never used GSync btw, only VSync). But yeah, you are probably right, I did start to see some minor artifacts even before it completely broke down, so it wasn't "working perfectly" after all, even for that very brief period. Kind of a shame (to put it mildly) if it's really the case that NVidia or Windows or whatever has some inherent problem with 23.976, as it's the standard frame rate for films.

[huhn]

if a dev still cares i got VVR working now. i need to test it a display that does vrr correctly not the TV but it's working.

i just had to quad the frame rate to 96 so it doesn't fail around with LFC.
the problem is the media player and the low frame rate.
so i forced deint on lavfilter and added ffdshow and forced deint there too (avisynth didn't work and should have been a more graceful solution) so i get 96.
after that i disabled all swap effects and it is already working decently.
the last and most important step was using a reshacked version of mpc-hc to trick the GPU driver into not using the mpc-hc nvidia profile.

rtss can be used to smoothing the frame times.

it either has AC3 nor dts listed.
it is so far behind it can not be used to playback a dvd...

not even aac is glitch free and the source for that is there github page...

then it has benchmarks with codec it supposedly can not even decode correctly...

just why?

The latest ffplay.exe does not recognize the audio codec in your file.
Thanks for confirming the reason for the issue...

is it possible to look into the dvd soft telecine frame time issue.
these very common 23p dvd can have frametimes for video which will results in massive judder. with deint forced it may not care about the repeat flags (which is actually preferable under many situations).

is it maybe possible that a 23p stream with repeat flags is retimed to 23p for proper playback?
a dvd stream with mpeg2 23p and repeat flags should always be save to assume that it is real 23p as long as the repeat flags are present switching to 29i is BTW. possible at any moment.

So if I understood correctly from a previous conversation, there seems to be pretty much a consensus that in most cases (where applicable) it's a good idea to always output 10-bit through GPU, but I'm still unsure if I should use auto 8/10 or also always 10 as texture format, and if not the latter, why exactly?

[huhn]

16 float.
how and where this is sued in mpcVR is not known to me but to do stuff really mathematically accurate you need at least that.

it's for better dithering accumulated errors from scaling, ycbcr -> rgb conversation and such stuff. don't expect much even with 10 bit it doesn't show the typical 10 bit banding so i doubt setting this to 8 actually make it use 8 but everywhere there is no measurable difference between 10 and 16 anyway so just use it.

10 bit output would generally be better then 8 bit assuming a perfect end device. end devices are not perfect at all they are far far from it.

[Amuat]

Thank you for your input. I think it was clsid who advised against it to minimize errors. So if clsid also cares to contribute, why do you two see this differently?


10 bit output would generally be better then 8 bit assuming a perfect end device. end devices are not perfect at all they are far far from it.

So are you saying that even the latest high-end devices are not for the most part particularly well suited for 10-bit output, or are you thinking on a much wider scale of devices old and new, budget and high-end?

[clsid]

It should be set to "auto 8/10".

Forcing 16bit will break/disable certain stuff, but you guys are stubborn anyway, so go ahead and shoot yourself in the foot. Or for those who think just because when number A is bigger than number B, then A must be better, shoot yourself in both feet.

It would be better if this option was removed, or ignored when using VP and limited to 100% shader processing.

[Sunspark]

Good test.
My result:
EVR - bad
EVR-CP -good(if use 16-bit float surface), bad if 8
madVR(bicubic60) - good
MPC VR DX9 -good(if use 16-bit float surface), bad if 8
MPC VR DX11 - good.

P.S. Verdict - EVR-CP/MPC VR DX9 with 16-bit float surface and MPC VR DX11 is the same quality as madVR bicubic60. So - we don't need to process chromium ourselves, DXVA2/D3D11 Video processor do it not bad :)

It's strange, because Aleksoid in that post at https://forum.doom9.org/showthread.php?p=1877825 found that there were cases with the test done at that time where 16 was better..

[huhn]

with VP on the error has been done by limited 10 bit VP out. yes.

that doesn't change that float 16 dithered to output bit deep is better.

btw. mpcVR has banding issue on window mode when the GPU is send 10 bit because it is send 10 bit in window mode which is been buggy with nvidia forever.

bigger is not always better.
It's strange, because Aleksoid in that post at https://forum.doom9.org/showthread.php?p=1877825 found that there were cases with the test done at that time where 16 was better..

yes i also see it like that but why doesn't dx11 need 16 where dx9 needs it. it is ignoring it and uses it or something? disabling dithering also doesn't do anything in DX11 mode in DX9 it does...

displaying a 16 bit gradation test with 10 bit buffer that isn't dithered is impossible it's 1023 visible steps simple math.

Someone asked about HDR Tonemap. You can try it for testing as a post-resize shader with the test build I posted, which has the SetHDRMetaData() call removed.
In the shader, set maxDisplayNits to whatever the display can handle, and maxContentNits to the "Maximum Content Light Level" value from the video; if there isn't one, set it to 1000.0.

HDR -> HDR tone mapping "works"

[clsid]

I still think the dynamic tonemapping (HDR passthrough with reduced MaxCLL) would be a good addition to renderer options. For the many monitors with bad internal tonemapping ability.
Could be just a simple dropdown option, something like: HDR output peak nits = Original/600/500/400/300/200

When the renderer does it, SetHDRMetaData() could be adjusted with the modified MaxCLL.

So if you do change your mind one day, here is a fork from which some code could possibly be re-used:
https://github.com/thefallentree/mpc-VideoRenderer/pull/1

That one also gives a choice between a few different tonemapping algorithms. Perhaps that would also be a nice addition?

[Sunspark]

Wait for V-Blank before Present
The renderer will wait for a V-Blank event before calling Present. This allows for more accurate frame output timing. This allows the SyncOffset graph to more accurately reflect frame output jitter.
This setting may affect video smoothness. Disabled by default to avoid annoying users with a sawtooth graph.

Adjust the frame presentation time
The renderer will wait additionally before displaying a frame to more accurately hit the required display refresh time. This setting helps smoothly play interlaced video with double the frame rate (50/60 fps) on displays with a high refresh rate (120 Hz and higher).

Wondering if Wait for V-Blank is intended to be used with a specific presentation path? E.g. Exclusive mode vs windowed mode which uses the DWM compositor, and also D3D9 vs D3D11 for both modes?

Who needs this, and in what situations? More information would be great, as would tests, preferably with comparison screenshots.
I posted a build and shader above, just for testing. The result: only one user responded, and even then, they just said it "worked."

[clsid]

It is not something you can easily capture in screenshot, would need actual photos.
But dynamic tonemapping is what most madVR users use. But of course that has more advanced tonemapping options.

At least the ability to choose tonemapping algorithm seems easy to copy, and that is not directly related to dynamic tonemapping ability.

sorry i do not use a system that needs it. so all i had to add was there is nothing it does wrong what so ever it was rolling off highlights as i excepted it would do. and there are quite a number of cheaper screens that really really really need that...

you can look up the issues with Nintendos new "console" and there HDR "calibration" issue and setup to do something similar for the games.

[DailyLama72]

I switched from mpc HC to mpc be.
Much better with audio, subtitles etc

I used the mpc video renderer and I use an sdr projector.
First everything looked fine. Then I noticed that some hdr movies look very dark.
I played with the nits config. One movie needs 50 nits, the next 100, one even 200 nits.
Since I don't want to change settings for every hdr movies I changed to madvr.
I have no problem with madvr hdr to sdr in mpc HC.
But in mpc be I have very often a brightness change. It's unwatchable.
Since it works fine in mpc HC it seems it can't be the madvr settings.
What can cause these brightness changes in mpc be when using madvr to play hdr to sdr? What behaves different than mpc HC?

Another strange thing: mpc HC correctly using the downscaling settings of madvr. But mpc be using the upscale settings for the same movie, first downscaling 4k to 0x0, then upscale to full hd. Abd yes, it's using the same madvr settings as I see in realtime which profile group in madvr it uses.

[huhn]

is it possible that for "passthrough" the nits can be unlocked which run the ToneMap.hlsl but still darker so user can use that to roll of this is not one of the. reinhard seems similar but not the same.

reinhard, mobios and hable remind me of hdr SDR settings for mpv.
mobios doesn't seem to be build for that?

[Amuat]

and he is correct it minimizes error.

Not the case that "I need proof or I'm gonna use 16 FP" (which I didn't use to begin with), but still very curious what are some typical errors introduced?


Another thing: there has been quite a lot of talk of FSE not truly being FSE in Win 11, but nevertheless I decided to experiment with it inspired by huhn's comment of 10-bit output being buggy in windowed with NVidia. Seems generally somewhat smoother (and yes, I do have full screen optimizations disabled in the exe), but what's more, this has been clearly the longest run of 23.976 actually working with 23 Hz instead of having to use 24, hope it lasts. Only downside I've noticed thus far is that you have to always go full screen twice as the mouse pointer sticks on with first try, but this is a very minor annoyance.

i can take a cemara out and show the issue.
i have a very very cheap smart phone somewhere around.

we had just "fun" with ffv1 you can test it with this: https://drive.google.com/file/d/1RaA9h1Lfpa-6i_V8rs9qYBxT1W5DYu-n/view not my file. this is 16 bit a similar result would happen if you would apply a deband filter if it isn't been applied in 16 bit and then dithered it will not do a proper job and still bands the same type of banding you get if you don't dither. with mpcVR in dx9 you can test all of this very precisely. with DX11 something happen that shouldn't you will not get banding with 10 so something forces it to dither before it is written int eh first 10 bit int buffer you can not truncate a gradient without adding banding.

there is no real point to FP32 except it could be faster cause the GPU does math in FP32 anyway (FP16 needs special code and will not perform well on old cards.) and can just store the results not needing to do truncation conversation, bit shifting or anything for the cost of Vram and memory bandwidth.

you can also test this in madVR if you want madVR can be limited to 10 bit in the trade performance options really not recommended and everything in madVR works anyway with the normal bit deep with no risk at all.

with FSE you can not show the player controls which will trigger the issue fake or real does not matter here. real FSE will not allow overlays the fake FSE will be affectted by steam overlay nvidia over amd overlay and so on beating the point of been exclusive but i'm sure you can see why they did that change.

It's kind of fascinating how challenging a field video rendering really is. Lots of papercuts.

Test version with HDR Tone map - https://disk.yandex.ru/d/1ID4GrXutRO7NA
There are clear differences between the algos, so feels like a good customization option for users to play with.
Any reason why the nits value isn't an integer in the option GUI?

What is the SetHDRMetaData behavior in this test build?

Bug? The OSD sometimes shows 0 as (second) nits value. Also after switching back to passthrough.

[clsid]

Can you split the tonemap algorithm choice into a separate dropdown and also use that algo for HDR->SDR?

HDR10: disabled/passthrough/local tonemap/ignore [...] Nits
Tonemapping: ACES/Reinhard/etc

[clsid]

Found some sample code to get EDID data:

void GetEDID() {
HDEVINFO hDevInfo = SetupDiGetClassDevsEx(NULL, "Monitor", NULL, DIGCF_PRESENT | DIGCF_DEVICEINTERFACE, NULL, NULL, NULL);
if (hDevInfo == INVALID_HANDLE_VALUE) return;

SP_DEVINFO_DATA DeviceInfoData;
DeviceInfoData.cbSize = sizeof(SP_DEVINFO_DATA);

for (DWORD i = 0; SetupDiEnumDeviceInfo(hDevInfo, i, &DeviceInfoData); i++) {
HKEY hKey = SetupDiOpenDevRegKey(hDevInfo, &DeviceInfoData, DICS_FLAG_GLOBAL, 0, REG_NONE, KEY_READ);
if (hKey != INVALID_HANDLE_VALUE) {
BYTE EDIDdata[256];
DWORD dataSize = sizeof(EDIDdata);
if (RegQueryValueEx(hKey, "EDID", NULL, NULL, EDIDdata, &dataSize) == ERROR_SUCCESS) {
// Process EDID data
std::cout << "EDID data retrieved successfully." << std::endl;
}
RegCloseKey(hKey);
}
}
SetupDiDestroyDeviceInfoList(hDevInfo);
}

This could be used to extract "desired max luminance" and "desired max avg luminance" values from EDID and maybe show them in OSD. Since that other API we tried gave values that varied depending on screen brightness setting, EDID should be more reliable.

Then perhaps setting the local tonemap nits value to 0 could behave like an automatic choice, which uses those values to choose a good target nits value.
Just an idea for a possible future improvement.

EDID does not always contain data on luminance. My monitor don't have it :)

[v0lt]

I don't think it's worth using EDID information when there are special Windows features.
As I understand it, EDID information is static, and we're interested in the current state of the display.

[huhn]

as a calibrator i can tell you displays do not know there current state just the variables set in them without the actual produced image by these settings. this is just a warning... they are not trust worthy at all.

if you want too i can read the TV without windows ACM and with it and share the "results" to share a sample size of one.

Test version with HDR Tone map - https://disk.yandex.ru/d/1ID4GrXutRO7NA

Sadly same problem. Hamnet (HEVC, Dolby Vision, Version 1.0, Profile 5, dvhe.05.06, BL+RPU, no metadata compression) or Black Hawk Down (HEVC SMPTE ST 2086, HDR10 compatible) are much too dark, but with the same settings Finding Dory (HEVC, Dolby Vision, Version 1.0, Profile 8.1, dvhe.08.10, BL+RPU, no metadata compression, HDR10 compatible) is fine.

[Amuat]

Though the method is different, is there any overlap between possible errors resulting from using FP16 for dithering and using an internal debander TVs often provide?

[Amuat]

Is there a filter somewhere that gives a slightly blueish tint that I could use in turns with the sepia one? I find it hard to stand B&W, a misleading moniker as a much more accurate one even with very good contrast would be 'mostly just varying shades of gray', and have thus far changed between customized TV profiles based on changing content (yes, I'm really that crazy), but realized that it would be much easier to just make a shader profile for sepia and another for the blueish one and just hotkey between them.

(As a side note, most of the content I watch is actually B&W and I love it, just not a fan of the grays though many people appreciate the "purity" of it. Many silent films got it right by toning and tinting is how I personally see it.)

[Sunspark]

Easy way would be to just use your monitor's preset to change the colour temperature. You can even do it manually.. R,G,B sliders in custom. You won't be able to change the LCD backlight itself which is fixed, only to block/allow amounts.

That is actually what I meant with using customized TV profiles, I've created custom color schemes for them, but I have Philips 810 and it's way more cumbersome than it would be by using hotkeys to apply filters. It's not like you can map numbers on the remote for different profiles, sadly. Also there are too few profiles available for use and full customization, and I'm wasting two for B&W content. Without the custom colors could easily use same ones I use for color content and free up room for environmental considerations which I would like to have for my current watching habits.

[Sunspark]

Maybe you can use DDC/CI software on the PC to switch between presets.

I'm impressed how well exclusive works even on Win 11. Barring any update breaking it, can pretty much already confirm at this point that 23.978 is finally fixed. And like you said, it is smooth, more so than windowed at any refresh rate, at least for me.

[Sunspark]

Yes, and it's a power-sipper too. On gpu-z there were gaps in the chart where the gpu load was effectively 0% on h.264 instead of continuous load when using quicksync copyback decoding with dxva scaling. I often use shaders, but for a dual-core of that age it's impressive.

It's a shame Microsoft quality is taking a dive these days with all their vibe-coded slop and "designers" working on Windows who don't use it as their own desktop. I'm typing this on my Linux Plasma desktop atm and while it's obviously not perfect, it's pretty nice that I don't have to worry about sloppers or middle-managers breaking something in it.

The stats graph in mpcvr is useful as a diagnostic tool with (older?) hardware that might not be recognizing a refresh rate correctly.

Last night I turned on the old TV and PC which had been left at 23 Hz. I noticed after watching and thinking it perhaps was not quite as smooth as it should have been that the graph was showing a sawtooth jagged line graph. Changing it to 24 Hz and back to 23 Hz again corrected the issue and the line was smooth again. Will see later if this applies also when waking the system up from sleep too, or only from power-on (since that one starts with the BIOS screen, etc.)

UPDATE: Google is adding Symphonia to chromium for both desktop and android - https://github.com/pdeljanov/Symphonia/issues/461

[Sunspark]

You need to make your argument as to why you think it matters in this project. The existing audio framework isn't broken.

MPC Video Renderer 0.10.1.2531 (https://github.com/Aleksoid1978/VideoRenderer/releases/tag/0.10.1)

Сhanges:
Added support for 'UYVY' format.
Improved handling of the D3DERR_DEVICEHUNG error for Direct3D 9.
Fixed conversion of 'AYUV' format using shaders for Direct3D 9.
Added a local tone mapping for HDR output (ACES, Reinhard, Habel, Mobius, BT2390, ST 2094-10). ST 2094-10 only applies to Dolby Vision.
Added Dovi Extension Level 1/2 processing for the local tone mapping, Level 2 for HDR to SDR conversion when using D3D11.

PS: MPC Video Renderer 0.10.1 are included in the MPC-BE 1.8.9.132 installer.

Using local tone mapping, if I leave DV on I get terrible clipping artifacts in Alien Romulus in the early part of the film where they're walking through the colony before Rain is told she won't be getting her travel papers and has to work in the mines. It's mostly the red colored signs and lights that have a zebra pattern on them with DV on using any of the local tone mapping modes where I can enter a nits value. It seems to not happen as much if nits are over 1000. Is the purpose of the custom nits to map it to my panel? For example a TrueBlack 400 panel.

Also I noticed some films get very dark with local tone mapping. Passthrough seems to be 1000 nits and isn't great but it's not that dark.

Where is screenshot with artifacts, better compare with HDR passthrough.
Also enable Statistics (Ctrl + J).

With Passthrough there is no issue. It's if I pick any other setting.

This also turns up when converting to SDR. The BAR sign and other red lights exhibit this behavior. I can't capture it in screenshots as the screenshots come out fine. I can capture it with my phone though.

Should there be a minimum hard limit of 1000 nits? It only causes the banding and artifacting if I try to set it to 500 nits.

Thanks for the continuous updates on MPC-BE, (https://minecraftoptifines.com) really appreciate the work. The player feels lightweight and smooth compared to other media players. I especially like the improvements in subtitle handling and performance. (https://drawingideas-net.com/) Looking forward to more updates and maybe enhanced streaming support in future versions.

current videos may not even work with the final draft. the spec is not finished yet. should be finished in the next month and worst case years.
this as far as i can see is not a real release yet.

[v0lt]

I don't see the point of adding an AV2 decoder to MPC-BE until it's officially added to FFmpeg.
And even after it's added to FFmpeg, there might be no point in supporting the codec. There have been some well-debated codecs before, but no real video has been released.

Wait for updates to FFmpeg and LAV Filters. :p

The problem is observed when using the DXVA2 decoder.

I think this is happening because you're using an AVI container and the decoder isn't processing some of the data correctly.

hardware vs software decode, GPU or even the OS to name a couple of issue sources.

People using the player are having problems with DVD playback. Freezing is common when navigating the menu. The program often freezes even at startup. The disc is flawless and an original factory release!

The comment about MPC-HC working with the DVD is interesting because it might also depend on the filter version in that player. The release version of LAV 0.82 took out hardware decode support for DVD because "DVD handling has a number of special requirements with handling the menu and such things which caused numerous bugs with hardware decoding."

The quote talks about the menu.. so..

[s0meone_new]

I have already written everything down.

1. Use disc.
2. Sometimes it freezes immediately, sometimes when using the menu, sometimes by itself when the player jumps to the next media.
3. Freezing means the player stops by itself. (the player CRASHES)
4. I also thought it was some internal software error in the player. Maybe something coding related.
5. That's it. :)

Ask AI
LAV Filters Hardware decoding support for DVDs has been removed

Why Was This Changed?

DVDs use the legacy MPEG-2 format, which requires a comparatively low amount of processing power compared to modern high-resolution formats like HEVC/H.265 or AV1.
Modern CPUs are perfectly capable of software-decoding MPEG-2 without breaking a sweat, making GPU hardware acceleration unnecessary for DVDs.
Removing this functionality helps simplify the LAV codebase.

What Does This Mean for You?

● Your videos will still play. You do not need a new graphics card or player. LAV Filters will automatically fall back to software decoding (via libavcodec) for DVD MPEG-2 video.

● No performance impact. Because MPEG-2 is an older, lightweight format, the transition to software decoding will not cause lag or dropped frames on modern computers.

How to Verify Playback

If you are currently watching a DVD and want to check if the video is decoding properly, you can follow these steps:
1. Ensure your LAV Video tray icon is enabled.
2. Double-click the tray icon while your DVD video is playing.
3. Look at the decoder status: instead of listing your GPU (e.g., DXVA2/D3D11), it will say avcodec.
If you are noticing stuttering or playback issues with your DVD and suspect it might be CPU-related, I can help you troubleshoot.
Let me know:
● What media player (e.g., MPC-HC, PotPlayer) you are using.
● Your current CPU and RAM specs.

[LigH]

Is it technically possible, for me as user, to add a button to the button bar which activates full screen mode by one mouse click? A double-click into the video interrupts it (it pauses for a tiny moment due to the first click before entering full screen mode and continuing to play due to the second click).

[clsid]

Of course that is possible. MPC-HC has a button option, has option to delay left-click in anticipation of double-click, can also assign middle mouse click to FS. So three solutions for same goal.

[clsid]

Regarding DVD issues.
If crashes -> post stack trace and/or dump. Afaik the MPC-BE crash handler can generate that.
If freezes -> use Windows Task Manager to create dump of mpc-be process for the devs to analyze.

[LigH]

That would be an advantage of MPC-HC. How may it work in MPC-BC instead, would I need to edit a theme to insert a clickable button?

[Klaus1189]

@LigH: https://drive.google.com/file/d/1zgrZ_-fK-15mar2QDKAp4OQyFCvxcMrh/view?usp=sharing

One option in MPC-BE for that

[LigH]

Yes, that works alright. There is even an option to enable fullscreen without changing the video mode, which seems to be even less disturbing. Thank you.

[Klaus1189]

I personally have had left mouse click for play/pause disabled even before MPC-BE was born (I was using MPC-HC back then). For this just blank out the marked filed and you can also use the Fullscreen without changing the video mode in the dropdownlist for double click.

How much does this improve the texture format in question? Is it still not a viable candidate next to 8/10 auto? Or is it even inherent in how it works that it never can be? clsid, huhn?

[huhn]

i do not know what that option does specifically. if you lower madVR to 10 bit internal you get massive banding all over the place.

if it would do some math in linear light you could even argue if 16 isn't to low. this stuff is complicated and depends heavily on the context.

When I open the menu with the mouse, then move the mouse pointer from one menu to the other, sometimes they appear empty. I am not able to screenshot this issue, I had to record a video with an external camera (https://www.ligh.de/test/MPC-BE_blank_menu.mp4).

Would you prefer a github issue?

[Klaus1189]

I can't reproduce this issue on my end. Did you try to reset settings? Portable installation?

I think you have enabled the "Use Blur Behind effect" setting.

[LigH]

Correct, v0lt. Disabling it helps avoiding this issue.

[Klaus1189]

Good catch, if I enable this feature on Win 11 latest build with all updates, all entries are empty/non existent, every time.

[Klaus1189]

I just noticed that one entry got to short for some reason. Too bad I only notice it now:

Again false positive. Upload to virustotal and check. Maybe it would be easier for Devs to upload the file to virustotal and post the clean check to prevent this posts here and issues on github.

It's work in SDR, limitation.

[Klaus1189]

For me it does not even work on SDR anymore. I remember it worked in the past. I tried changing several things, but is it possible that it is bug in Nvidia driver? I don't want to search for older drivers now.
Here is what it looks now for me: https://drive.google.com/file/d/1XHx89FgUDSTo80OvqUJfSmVHUp5DJ-Vs/view?usp=sharing

This is on two different PCs, one with RTX40 card, one with RTX50 card and both latest GRD driver 610.62 from 2026-06-16

A small MPC-BE settings help please, 1.8.9.324 dev, was the same with earlier versions, so surely my fault.
Win10P64, GPU MSHybrid Mode iGPU Intel750UHD + dGPU nVidia RTX3080, Driver 561.09 -> 4K internal display.

Having specified MPC-BE as .m2ts default player, then using BDEdit -> Preview I can get the MPC-BE icon to appear in info area.
Process Explorer sees MPC-BE loaded by BDEdit, small CPU activity, nVidia RTX 3080 shows activity running mpc-be64.exe, but no video window pops up on screen, Audio will play.

It takes a separate clicking on that MPC-BE icon in info area, then the the video window will pop up, content will play together with audio as desired.

What helps: Specifying MPC-HC as .m2ts default and use BDEdit -> Preview the video window starts playing video+audio content from the start, no further interaction needed.

To get MPC-BE being called by 3rd app playing without interaction, did I overlook any MPC-BE setting and which could it be ?

Why doesn't DXVA work with MPC Video Decoder? :confused:
Microsoft/LAV Video Decoders are fine. The graphic card is Intel HD Clarkdale.

no H264_VLD_NoFGT only the intel version the decoder may not even try to use it.

[v0lt]

no H264_VLD_NoFGT only the intel version the decoder may not even try to use it.
It is used. In MPC-BE it is called "DXVA2_H264_VLD_Intel", in LAV Filters it is called "DXVADDI_Intel_ModeH264_E".

We don't have any old Intel graphics adapters to modify the decoder. And we don't plan to buy any antiques for this purpose.
PS: As far as I know, support for Sandy Bridge graphics adapters works well in MPC-BE. Older graphics adapters may cause issues.

I encountered black screen issue with latest nightly builds:
Automatic fullscreen start is enabled. Video is playing in fullscreen and for a short moment screen is black and comes back, audio is still playing fine. It is reproducible happening every time.

1.9.1 stable is fine, but 1.9.1.6 dev is already affected.
Testing 1.9.1.1 dev would be pointless since its only change is naming to dev build. If you want me to try a testbuild or else let me know.

I know it now. It is SuperResolution. If I turn it off, it doesn't flicker. But in 1.9.1 stable it worked fine.

Would be nice if Nvidia had an API, so it would be displayed in MPC Video Renderer stats.

Yes, i know. I missed some 3D settings in Nvidia control panel for this instance of MPC-BE. Sorry for wrong alert.
It was the switch of my screen between variable refresh rate mode and fixed refresh rate mode.

NV don't have API for control/check SuperRes.

In the CD3D11VP::SetSuperResNvidia (https://github.com/Aleksoid1978/VideoRenderer/blob/52c8ac0885a8f9c098fd5f8adbd257aa572f0dc7/Source/D3D11VP.cpp#L712) function, we call the ID3D11VideoContext::VideoProcessorSetStreamExtension (https://learn.microsoft.com/en-us/windows/win32/api/d3d11/nf-d3d11-id3d11videocontext-videoprocessorsetstreamextension) method, which always succeeds. Therefore, we don't know whether SuperResolution is actually enabled or not.
