Media Player Classic Home Cinema (MPC-HC) - DXVA!

[Mercury_22]

Yep, it would indeed probably be better to let the x64 build use "mplayerc64.extension" instead of "mplayerc.extension" for its file associations. Should be an easy change for the devs.
AFAIK you have access to the SVN so ... can you please make the change ? If you got the time to spare :thanks:

Issue 1 - Upon Launch of 23.976 MKV file Playback is very jerky
I have the exact same problem as you, and I also have to right-click for the sutter go away, so yes, I can also reproduce this problem exactly as you described.

I always use the latest SVN and this has always happened since I can remember. Either is an old introduced bug, or has always been like that.

[nevcairiel]

I actually had the same issue with stuttering when using auto-refresh-rate switching. Changing it right before launching MPC-HC works fine, however. :)

[terminaldawn]

Do either of you have issues with dropped frames in VC-1 mkv files?

If not what are your settings?

How many dropped frames? Across the whole movie? Only on the start?

What I normally do is: open the movie file, change to fullscreen, then MPC-HC auto changes the resolution to 24Hz and I have to right-click to select something and cancel, for the stutter (Issue 1 you described) to disappear. Then after that the movie plays flawless until the end. No stutter, no jerky, nothing.

So, where or when exactly does Issue 2 happens? Please detail more.

I get exactly the same thing - have to right click and bring up the options menu to stop the stuttery playback.

The other glitch if it's the same as mine is a little jump every 40 seconds or so, which I put down to try to correct the 23.976Hz movie playback rate with the 24Hz TV.

[v0lt]

I did a full support for "in24", "in32", "fl32", "fl64" (both big-endian and little-endian) in the mov files.

To solve that little jump I use Reclock to play the 23.976 movie in 24fps so it matches the 24Hz and the video is 100% smooth.

Did you enable the options in MPC-HC to see if you are dropping frames?

I would say in a minutes time i will have about 20 dropped frames (I am guessing but I can get the exact number later). Either way its pretty annoying. The issue starts right away after I do the options toggle trick. It only happens on MKV BluRays that I have ripped that are VC-1 (%100 full quality using eac3to). AVC are OK. I am guessing I just dont have something set up correctly maybe? Also note, everything plays fine in 60Hz. No itintall stutter and 0 dropped frames. Can you maybe post your settings?



As a side note. We should probably submit a bug for the initial stutter upon launch with 24 Hz. It seems everyone that tries to do this has this issue. I am beggining to think 24p isnt worth the hassle.

[robpdotcom]

@terminaldawn:

1. What filters do you see when you are playing a VC-1 file? I'm interested in which decoder is being used, if it's DXVA, etc.
2. Have you tried madVR? The stuttering from switching to 24p goes away very quickly with madVR, as soon as it enters exclusive mode.

please excuse my ignorance. How do I tell what filters are being used when playing a file?

I did a quick search on madVR (never heard of it before you mentioned it) and this looks impressive.

I know I need to lurk more on these forums but if someone can point me to a faq or a wiki for HTPC playback I would greatly appreciate it. It seems as though madVR is WAY better than FFDshow for video. I need FFDshow to passthrough HD Audio though :)

madVR rocks. In my 32 bit environment that's what I use. It's phenomenal.

You can use FFDShow Video decoder to pass video to madVR.

To see what filters are being used, just right-click on the screen and click "filters".:rolleyes:

BTW: madVR and FFDShow are 2 different types of "filters". MadVR is the renderer, FFDShow is the decoder. So, you would use something like: FFDShow video decoder, FFDShow audio decoder, and madVR video renderer.

Don't feel bad about what you don't know. All this stuff can be a bit overwhelimg at first, but the more you read these forums, the more it starts to all make sense.

The filters I see when playing a video and getting dropped frames in 24 Hz are:

Default DirectSound Device
Enhanced Video Renderer (custom presenter)
Audio Switcher
MPC Video Decoder
ffdshow Audio Decoder


Note, these are the same filters I see with videos that do not drop frames in 24 Hz.

[terminaldawn]

So I INstalled madvr. It took me a bit to figure out that it only works in 32bit version of MPC. So I installed the 32bit version of MPC-HC and enabled it under Output. It doesnt appear to be working correctly. There is a green bar at the bottom and everyting is blury, kind of like a 3d Image or something.. WTF.

I have an i5 750, 4gb of ram and a HD 5850 so this shouldnt be a hardware limitation.

Any ideas?

Oh... another thing. I have Auto Select enabled to chagne output to 24 Hz, and it doesnt even change the output to 24 Hz.

[Stomp]

I use MPC-HC 1.4.2499.0 on Windows XP SP3. I also have two monitors. If a video is playing and I move the window from one monitor to the other then MPC-HC either freezes and uses 100% of the CPU or just crashes.

Does bicubic -1.00 is the best resizer for high quality?

Depends how much you are resizing. Personally, I prefer A=-0.60.

This problem is not corrected in the last version of mpc-hc 2687 and exist since more than two years
http://sourceforge.net/apps/trac/mpc-hc/ticket/48

With some blu-ray movies, some subtitles are not displayed with MPC-HC 1160
(this problem exists from the start of HD subtitle support).

When two subtitles must be displayed in the same time, only one subtitle is
displayed.

I give you an example of video (ten minutes cut in 7 parts)

The problem appeared between 8 minutes and 9 min30 during the generic.

There is two subtitles normally displayed: the subtitle of song and the
subtitle of text displayed on the screen. Only the subtitle of the text
displayed on the screen is displayed and not the subtitle of the song.

I try with powerdvd ultra 7.3 and it works very well. The both subtitles
are displayed.

Ok, after upgrading I found that the behavior of the subtitle positioning has changed, which seems to be because of commit 2620. While I agree that this should be the default behavior, so that beginners will have the subtitles correctly positioned, this should be done by setting the registry key Gabest/Media Player Classic/Settings/SPDefaultStyle and not by forcing this setting in the code. Now people who do not want this behavior must deactivate it for every single file they open because the check box in the settings does not work anymore. If you have a lot of styles you have to do quite some clicking - and every time you open a file. Please revert the patch and simply change the default value for SPDefaultStyle. (Last Number must be "1")

r2620 changed only the default value, did not prevent you from change it later, so I don't get your meaning of "check box in the settings does not work anymore"?

The same will apply whatever the default value is, what if your lots of styles all need the default value been checked? So we are not able to choose a value to satisfy every needs, besides "While I agree that this should be the default behavior", seems you agree this should be the default value too. :)

If we revert to the old behavior and just make the box marked black by default then everyone would be satisfied.

By "lost all functions", I guess you mean the settings here will not be inherited by all other styles? You're right about that.

I've made some changes, could you try it and tell me if it works? http://www.mediafire.com/?bzg9w1irgzrznii , you may need to reset the settings first. :thanks:

Yes, that seems to do it. It behaves like the old versions and it checks the box with a black mark (instead of grey in older versions). Thank you.

[Keiyakusha]

btw i always said that this option should be moved into "subtitles" menu (somewhere near "override placement") instead of "default style" because it has nothing to do with the style but changes the way player renders the subs...

Maybe you're right, since I didn't see lots of video with complicated subs , I don't have a saying about subs. :)

If you have good ideas of how those options should be arranged, you should open a ticket to make sure it will not lost in this thread.

[clsid]

Ideally, the setting should only have effect on subtitles that don't have any explicit positioning information.

Subtitles with positioning information should always be placed relative to the video frame. Perhaps a flag could be set whenever a positioning tag is encountered during subtitle parsing. That flag can then be used to override the current positioning option, to enforce positioning relative to the video.

Subtitles with no positioning information should be placed relative to either the video or the window, whatever is the preference of the user. Many prefer subtitles below the video in full screen (thus relative to window). So that should be the default imo.

[clsid]

^this!
That would be awesome.

Slightly related (now that there seem to be people interested in working on the subtitle part of mpc-hc):
The internal renderer sometimes messes up positioning when going fullscreen (or at least when the display has a different AR than the video).

In bug tracker, It's writtent that nevcairiel take car of this problem since two months but no news about this problem.

@Nevcairiel could you answer me about this problem?
Thanks

[MPC-HTPC]

Hi ikarad,

IMHO nevcairiel was put as owner of the ticket you opened on the trac because he is working on a new spillter (LAVFSplitter (http://forum.doom9.org/showthread.php?t=156191)), which should be integrated into MPC-HC once it is finished (but according to nevcairiel don't expect anything this year). Anyhow, this is the reason why all splitter related issues on the trac were assigned to nevcairiel. So maybe when LAVFSplitter will be integrated into MPC-HC your problem is solved, but until then you either have to be patient or just install the current beta builds of LAVFSplitter.

Hi,
First of all, I'm not very good in English so please forgive me for my grammar errors.

My system is Core i5 750, 4 Gigs RAM, Nvidia 7300GT video card.
I have a MPC-HC lastest version installed with ffdshow, directx 9. I use ffmpeg-ht to decode my H264 videos, using CPU to decode. I use enhanced shaders in MPC-HC, and it works very well with 720p videos, CPU loaded about 10~20%, didn't drop any single frame. But the problem is, when I watch 1080p videos with shaders (combined SD->HD & sharpen complex 2), many frames are dropped. I just got about 19~20fps with an 23.976fps video, but the CPU only load about 20~30%, not fulload. When I disable the shaders, it become smooth.

Please help me solve this problem, to get my 1080p videos smooth with the shaders enabled.
Thanks in advance!

[cooz]

Hi guys!
I'm searching some code (probably somewhere around RTS.cpp) which controls size of subtitles relative to video frame size. As much as I understand it, now it's calculated from frame height, so when playing movie in fullscreen subtitle size is different for 16/9 and 2.20:1 format footage...

I'd like to find magic line: subSize = magicNumber / frameHeight; and replace it with frameWidth.
I hope it's not much more complicated than that and I'll be really grateful for any help :)

your GPU is rather weak compared to your CPU. you can try upgrading it but if that's not an option, set the shaders to run in software.

Does bicubic -1.00 is the best resizer for high quality?

Depends how much you are resizing. Personally, I prefer A=-0.60.

Well, actually, I prefer spline64 or spline36 with madVR, but that is another story.

Do not ask "What's the best?" when the answer to that question can only be "Depends on your taste." ;)

The differences between the various resizers is mostly the amount of cpu or gpu usage required, and the higher the better the quality.

Maybe someone can explain the differences better? we could add that to the manual and tooltips.

For example:
Bimagical: sharper more detailed, but with added ringing (+/- 5%)

[LigH]

Subjective image quality is not a measurable value. Some prefer it sharper with more fine details, some prefer it softer with less aliasing.

Furthermore, the impression of the result may also depend on the scaling factor; users may prefer e.g. one resizer for resizing 720 to 1080 lines (factor between 1.0 and 2.0), and another for resizing 480 or even 240 to 1080 lines (factor greater than 2.0). Not to mention downscaling (factor less than 1.0).

But I do agree that a warning about possible ringing artefacts would be recommendable for some variants (especially sharper Bicubic functions).
__

As far as I remember, Bilinear should be preferred for downscaling. Bicubic filters are often more convenient for upscaling, but the sharpness is a matter of personal taste, and sharper variants (larger absolute value for A) may cause ringing artefacts – due to the Gibbs phenomenon (http://en.wikipedia.org/wiki/Gibbs_phenomenon).

[namaiki]

As far as I remember, Bilinear should be preferred for downscaling.
I found (checking text in the video) that lanczos kept the text more readable.

Bicubic filters are often more convenient for upscaling, but the sharpness is a matter of personal taste, and sharper variants (larger absolute value for A) may cause ringing artefacts
Also, I also found that there was blocking, but nothing as bad as like with lanczos.

[LigH]

@ namaiki:

We are not talking about AviSynth offline resizers, but about MPC-HC realtime resizers for Pixel Shader 2.0?

Version 1.4.2667 did not have Lanczos implemented, I believe.

[namaiki]

madVR does spline and lanczos resizing during playback.

MPC-HC by itself only does bilinear and bicubic; and if you will count it, whatever EVR uses and whatever your GPU will use in Overlay Mixer.
I'm actually a bit curious as to what scaling algorithm my GeForce 9600M GT uses. I'm quite sure it's not bilinear.


edit: though I do get what you mean since this is the MPC-HC thread.

[Guns N' Roses]

I wanted to seek help with proper 24Hz playback. I have Samsung LA40A650 (PAL version of LN40A650), which supports 1080p24.
However, if I set the refresh rate to 23Hz in ATI CCC, and try to watch videos on my HDTV using MPC-HC with EVR CP and DXVA, they stutter/judder incessantly. There is no other refresh rate other than 60Hz that works without issues. I've tried reinstalling ATI drivers and MPC-HC, but nothing worked. This also happens with software decoding (CoreAVC). My config is i7 920, ATI 5870, Windows 7 x64.

But if I use madVR in full screen exclusive, I am able to get smooth playback. So I wonder why EVR CP behaves the way it does?

[namaiki]

Is that with one screen, or two at the same time?

Try disable Aero.

The problem is probably in dscaler, and maybe in the mpc-hc filter menu handling.

DEP means a value is being written to read only memory(or a similar buffer overflow type attack is accidently occuring), this could result in a system crash if not blocked.

EDIT: chances are high this workaround will reintroduce many of the other older crashes.

[GTPVHD]

Yes, do not accept patches or workarounds that turn off the security features like DEP or ASLR. This should be fixed on Dscaler5's side, not MPC-HC. Recently MPC-HC's Heap Corruption Detection exposed bugs in another external Dshow filter which was crashing and it was fixed in that filter's code.
