Media Player .NET (MPDN) - D3D HQ GPU Video Renderer [v2.49.0/v1.31.0 27 Dec 2018]

[vinnytx]

I hope 10-bit support will be improved.
I mean that it should be available even in windowed mode.
Also, 8-bit videos should not have 10-bit output

[madshi]

Why should 8bit videos not have 10bit output? Videos are YCbCr. Output is usually RGB. The conversion is floating point math, so you have more than 8bit after YCbCr -> RGB conversion.

[vinnytx]

I thought that conversion was lossy.

[huhn]

yes float to integer is lossy.
but float to 8 bit is more lossy than float to 10 bit.

[vinnytx]

I have problems when I play 4k 10-bit videos in fullscreen. I have this error.


I tried many settings in "Video Renderer" > General/Presentation/Composition and I couldn't solve the problem.

You don't have enough memory on your GPU apparently. Are you using any renderscipts? Those could make things worse. I think SSIMDownscaler in particular could end up using quite a lot of memory.

Thanks
My video card is 960 gtx with 4GB. I don't use any render script. Have you tested the video I posted?

Usually these sorts of problems are related to your graphics card driver installation, uninstall and then reinstall the latest ones.

[vinnytx]

I uninstalled and reinstalled Nvidia driver and nothing has changed.

I found the problem: when I enable DXVA2 copy-back in Lav Filters x86 the problem occurs.
No problem with MPDN x64 and Lav Filters x64

[Shiandow]

Are you sure MPDN is actually part of the problem? Does Lav Filter x86 work when you use a different video player?

[vinnytx]

Yes, I'm sure. Zoom Player and PotPlayer don't have this problem

[stax76]

Any news on the 2880 DPI issue? I've my own player now but still follow development of other players.

I've had a quick look and it looks like MPDN just didn't like it when it had to resize before it had a chance to initialise everything. I've managed to fix it.

Surprisingly most things actually worked. Apart from some small cosmetic problems.

Still not sure why the x64 vs x86 MPDN would behave differently. One possible explanation is that there is a problem in the settings of the x64 version. Also, the error dialog should have a button to copy the detailed information, if you could get the stacktrace from there I might be able to figure out where the problem occurs.

Also, there's still the possbility that you're actually just running out of GPU memory, and that minor changes in settings affect whether you run out completely or not.

[vinnytx]

I have problems with MPDN x86.

I uninstalled x86 version and I installed x64. At the moment I can't do other tests. I tried MPDN x86 portable version and it gives me an error regarding filters that are not properly configured (video graph failed to render). That's not a problem since I configured my pc for x64 video players

I'm encountering a problem during playback of:
http://tracker.minglong.org/torrents...5D.mkv.torrent

At 20:06 (twenty minutes and six seconds) into the video MPDN stops responding. I tried running in debug mode, but it didn't generate a crash dump. My settings are as follows:

MPDN 64-bit edition
version 2.48.0.3603
XySubFilter with reduce aliasing checked
Prefer: Image Quality
Always use new OpenCL Interop API (I tried disabling this and restarted, but it still crashed at the same part, so I have ruled this out)
Presentation API: Driect3D 11
Graphic Adapter: Nvidia GeForce GTX 680M
Video Renderer:
Colormetric: Automatic
Output Range: Full
Video Output bit depth: 10-bit
Script Chain Deband -> SuperChromaRes -> Super-xBR
Ordered dithering
I tried in full screen and in a window, and both crashed but anyway here is what I'm using for scalers:
Luma up: Jinc with anti-ring
Chroma up: Jinc 4 tap with anti-ring
Luma Down: Softcubic 75
Chroma down: Bicubic 75

If you need any more info, or testing with another setting let me know.

BTW: I ran the video with MPC-HC (with MadVR) and didn't encounter the crash/freeze.

[carpedee]

I really like this video player, I feel like it puts less strain on my cpu than MPC used with the LAV filters (DX11 helps a lot I guess).

I have a few questions/suggestions regarding some features I didn't find:

- Is it possible to edit the hotkeys like the one to enter in fullscreen mode for example?
- Is it possible to run several instances of MPDN at the same time?
- Is there a hotkey to take a screenshot when playing a video?

[kingpage]

I've just been reading up on Madshi's NGU (NG1). It's very impressive. Is there any plan on bring it to MPDN? Does anyone know if it's easier to run than SSSR (SuperxBR, NNEDI3, etc)?

[aufkrawall]

NGU will remain madVR exclusive and questions regarding it should be discussed in madVR thread. It got different quality settings and the performance costs range goes from relatively close to Jinc to ~NNEDI3 64 neurons.

[Heaud]

Is there a way for MPDN to gain window focus when opening a video? Everytime I open a file, the video loads but does not gain focus. Operating system is Windows 10 64-bit with Creators Update.

Whether NGU will be brought to MPDN, is up to Madshi, and really there's no reason for him to help improve a video player which uses a different renderer. Despite that Madshi has already helped MPDN quite a bit in various ways, but expecting him to implement all of MadVR's functionality in MPDN is just not realistic.

As of now that's the expected behaviour when MPDN is already running when the file opens. It would be fairly easy to change that with a player extension.

You can make MPDN stay on top while playing, which might help. You can enable this in the context menu > Window > Always on Top. And you can limit it to only stay on top while playing in Options > General > Window.
