madVR - high quality video renderer (GPU assisted)

[el Filou]

@ttnuagmada have you tried disabling fullscreen exclusive mode? (I think it's enabled in the default madVR settings)

[Siso]

@ttnuagmada have you tried disabling fullscreen exclusive mode? (I think it's enabled in the default madVR settings)

Since a few releases, it is disabled by default.

[ttnuagmada]

@ttnuagmada have you tried disabling fullscreen exclusive mode? (I think it's enabled in the default madVR settings)

I have not, but the lockups dont occur at full screen. It happens the second the video is opened in a window. I don't have it set to go fullscreen automatically.

[ttnuagmada]

Use the debug version. Then you can see what madVR does right before the hang occurs.

Scan your harddrive for bad sectors.
Scan for damaged Windows files (https://www.ghacks.net/2018/03/16/use-dism-to-fix-issues-sfc-cant/).

i'll try this when i get home.

Nvidia driver 430.86 released.

Madvr uses the private nvidia api to enable hdr.

Can someone or madshi show the api?
I want to make a script for other things to enable hdr by command line interface.

@Madshi can you post the API, please?

Thanks, that's what I'm looking for.

The white papers even bring the code ready.
I'm just wondering, the APIs are part of nvidia drivers now? Or those need to be installed?

If I'm getting this right, all I need to do is copy and paste the code to the player and it will trigger HDR.

Also again, much appreciate the help.

[Alexkral]

No, you don't need to install anything else.

[veggav]

Great thank you.

So today I checked. Playing video on my kodi box vs playing with kodi using madvr/dsplayer.

And it seems Kodi on pc is indeed experiencing mini stutters, while my kodi on my media box is 100% fluid.
It's frequent but with spaces of it being fluid aswell. So I was doubting my own eyes.
But it just barely annoyed me, sometimes more then others.
Thus I had to be sure and checked.

I check madvr OSD and there don't seem to be dropped/ repeated frames or presentation glitches.
Yet mini sutter is still present.

Im on 430.39

I had heard this was a thing that happend often to RTX 2080?

Can any RTX user tell me how they eliminated this problem?

For now I am just playing the same movie both on my pc and kodi box at the same time.
Trying to play them back at the exact same time for my ambilight to be correctly timed with the video source coming from android kodi box. to still have 4k HDR Ambilight with the video.(which is impossible for the android box alone I have, which is why I would prefer PC now, but mini stutters..)

These settings solve it for most people:

[chrisssj2]

You mean this?
This is NVIDIA Profle Inspector tool with an optimized profile for MPC-HC/BE.

Download

Most important settings it uses:
Power management mode = Adaptive
VSync = on
GSync = off
SLI = off
Prefer NVIDIA on Optimus systems

Already using those ssettings.
Though I dont see a prefer nvidia on optimus setting.

Anyway these settings make 0 difference appearently.

[Daicon]

The only option in Kodi to use MADVR with HDR goes through Kodi DSPlayer ???

There is no other?

Isn't this the version with the CPU usage bug? Update.

[huhn]

this is the version where telemetry can create a huge load on the CPU.

[chrisssj2]

Isn't this the version with the CPU usage bug? Update.

So which version should I be using?

[garson]

Hello everyone.
Occasionally I am experiencing stuttering in moving scenes, but no dropped frames or presentation glitches. :confused:
How can I track what is causing this?

I enabled full screen exclusive mode, looks like it is helping a bit but still I see it.
Does FSE still makes sense?

I am using madVR v0.92.17 with latest MPC-HC on Windows 10 64 bit.

:thanks:

[Asmodian]

430.86 has been working very well for me. 430.53 fixed that bug.

Hey guys on my laptop when I use madvr and MPC-HC some videos (not all of them, but most of the mkv's) became colors washed out in fullscreen. (btw this does not happen on my external monitor)

[Charky]

Washed out colors (or crushed blacks) usually come from a wrong 0-255/16-235 setup.

Check your driver and/or monitor settings.

[Asmodian]

On your laptop madVR should be set to output full range 0-255, but it only happens in fullscreen? If that was the issue it should not be only when fullscreen. Any more details, like OS, GPU, driver, laptop model, etc?

[baker99uk]

I'm wondering if there is any disadvantage to using CUVID in the LAV video filter? Is D3D11 better quality? The reaaon I ask is that D3D11 drops lots of frames at default settings in madVR, if I reduce everything I can just about get it working but then I get random artifacts, madVR doesn't report any presentation glitches though. With CUVID everything is perfect even with higher settings in madVR. I also noice huge cpu usage using D3D11 , I get similar results with dxva2 native or copy back to D3D11.

I'm trying to watch 4K HDR content in 3840 × 2160 resolution, 23Hz, RGB Full, 12 bit, using a 6GB Nvidia 1060, CPU is i5 6400, 16 GB of RAM, latest Nvidia drivers, I've tried both the standard LAV filters and the nightly builds. This is on MPC-HC. TV is LG C6.

If there's no negative effect to using CUVID I'll carry on using it, I just can't seem to find the answer searching around.

[el Filou]

CUVID puts the GPU into higher performance state. Maybe that's why you get fewer dropped frames than with DXVA but it shouldn't happen.
Check that the power saving mode in NVIDIA control panel is on Adaptive.

[clsid]

CUVID puts your GPU in high performance mode (always highest clock speed). This is the only 'disadvantage', but only if your care about power consumption. Quality is identical to other decoders.

Adjust your NVIDIA settings to use "Adaptive" power mode. By default it uses "Optimal" which give bad performance.

If to other hardware decoders give high CPU, then they are probably not working correctly. Perhaps you have multiple GPUs? In that case, DXVA2/D3D11 have option to select the correct GPU.

[clsid]

Already using those ssettings.
Though I dont see a prefer nvidia on optimus setting.

Anyway these settings make 0 difference appearently.The NVIDIA control panel doesn't show all options. The tool in the my download link does show it. That specific option is only relevant for Optimus laptops.

The included profile applies specifically to MPC and doesn't touch the global settings.

[baker99uk]

After a bit more digging it seems external LAV filters are only using video accelleration when CUVID is enabled, the internal filters with MPC-HC do all use video acceleration but of course there's no D3D 11 option. I'm guessing this is a question for the LAV forum rather than here.

[baker99uk]

For anyone else with the same issue - Using LAV 0.71 allows D3D11 hardware acceleration for me, any newer versions break it, also the adaptive power setting helps too as suggested above.

Which OS are you on? There is no reason D3D11 should not work, it works for many other users just fine.

Would you report this in the LAV thread with all hardware, OS and video details?

Will do, have been doing various tests all day so will try to do a thorough report in a bit

[mclingo]

the only other way to do it is use kodi with a madvr supported external player like mpc-be, might as well just use kodi ds, its old but it still works fine.

Intel HD 630, RTX 2080, GE75 Raider 8SG, Windows 10 1809.

Only some mkvs does that on laptop monitor when fullscreen. Everything is fine on external monitor.

maybe start with a screen of the OSD.

Sure, here it is. I think watching full hd (on full hd screen) I don't see this issue, but HD and SD I occasionaly see this.
Screenshot is 720p movie.

[ryrynz]

Asmodian, how does HD upscaled to 1440P @ 120hz Smooth Motion look? Also is 4K worth downscaling with SSIM 2D to that res for 120hz SM? Just curious..

[grendelrt]

I have a weird issue. I used the report 2020 to display option to do some testing, and now even when I am on the desktop and in SDR on 709 material, my display is still getting reported BT2020. If I switch sources to my Oppo player it clears, but no matter what I do now on my computer it is stuck sending the BT2020 flag. Is there any way to clear this?

Edit: A full DDU uninstall of the drivers seemed to have fixed it. Isnt that option supposed to work as a toggle though? If I uncheck it, shouldnt it turn that flag off that nvidia is sending?

I have noticed the same issue recently. Yes it should work as a toggle. I haven't had a chance to debug it, but it definitely doesn't work as it should. It could be a change in madVR, as I haven't changed the OS or GPU driver (I'm testing 430.86 at the moment but I get this issue with 385.28 to).

Please could you report:

GPU & driver version
OS version and build
madVR version

Anyone else noticed this?

[Asmodian]

Smooth motion at 120Hz looks like the native refresh rate to me, the resolution and smooth motion don't really interact in my experiance. 2160p is noticeably better than 1440p for both 1080p upscaled and 4K (obviously) but 1440p still looks very good with good scaling. Smooth motion does not make SSIM 2D any less helpful either, in my experiance the extra details from SSIM are mostly only visible when not in motion and for 24p at 120Hz smooth motion does not noticeably soften the image anyway.

Well that's a good thing, but I'm kinda disappointed.

Am splashing out on a Pana FZ950 OLED, no more downscaling for me, gonna miss the plasma refresh resolution but there's a lot to gain with an upgrade now.
Even Sony's BFI isn't good enough that I would want to use it as the flicker bothers me.

A pity every display technology we've had replacing the previous one has gone backwards in terms of motion resolution.

That's good, so finally someone can test chroma 4:4:4 and judder free playback with PC mode @ custom 23Hz on Panasonic :)

[miroslav22]

Hi,

I'm looking to buy a new Nvidia GPU for madvr processing but I want the best processing power for a reasonable budget.

A 1080 is only roughly 35-40% faster than a 1060 in standard 3dmark benchmarks.

However am I correct in thinking that the processing capability of madvr would be more linearly proportional to the number of unified shader cores in an Nvidia GPU? Or is it more complex than that? ie would a 1080 with 2560 cores have half the rendering time of a 1060 with 1280 cores (assuming identical source and settings)?

Thanks for any advice

[chros]

That's how it works, yes. I have a used 1060 6GB and it's enough for me (using HDR passthrough) with a 4k screen. But if you can get similarly priced better card then go for it.

It is supposed to be as good as gets for current displays, particularly the color accuracy of its internal HDR 3D LUTs. Probably won't be disappointed with it. You will want a 65" screen if possible if you are moving to a 4K display and care about visible improvements from upscaling, which I would assume you would.

welcome to the OLED club, guarantee you wont be disappointed but watch out for 5% black vertical banding, its much better than my first gen 4k OLED but it can still be a panel lottery for OLEDS.

[tp4tissue]

Quantum Oled is suppose to fix all that, and reduce visible burnin as well.

ALTHOUGh.... it's still oled, motion clarity will be meh... :devil:

[tp4tissue]

Asked this question a while ago, no one knew, How is the 980 Ti for NGU performance. It's got lots'o Cuda cores, and it's cheaper (used)

I think most people with overclocked 2-series and above i7 can push 4K on CPU if they know what they're doing, leaving GPU just for scaling..

[distobj]

Hi. After just upgrading to the latest Nvidia drivers (after being stuck at 385.28 forever), I've been unable to get HDR working satisfactorily in fullscreen mode in either Potplayer or MPC-HC, despite working perfectly in (non-fullscreen) windowed mode in both players.

MPC-HC exhibits the most curious behaviour, as HDR will enable if I move the mouse on to the screen, or let the control panel appear at the bottom; once I hide the panel/mouse, HDR disables again.

Potplayer gets stuck in a perpetual loop once entering fullscreen mode, making viewing the content unwatchable.

I've tried with and without the "enable automatic fullscreen exclusive mode" options (the above is the behaviour without it set). The behaviour differs slightly when enabled, with MPC-HC behaving as Potplayer does as described above.

I'm using the latest MadVR with Nvidia 430.86 drivers for my 1060 6GB card, and an LG B7 TV.

Thoughts? TIA.

[chrisssj2]

430.86 has been working very well for me. 430.53 fixed that bug.


I am still experiencing mini stutters with my RTX 2080 after going to 430.86 and using the nvidia profile.
Can any RTX user confirm they have solved it?
