[solved] Media Portal crash playing mkv HEVC (1 Viewer)

[may24]

Hi all,

I've noticed that the Mediaportal Player crashes when I try to playback HEVC Videos encapsulated in .mkv
There're no problems when the video is in .mp4

Also there're no isues watching the matroska clip with MPC-HC or VLC ...

Hello, it will be nice to post logs so MP dev @Sebastiii colud investigate your issue.
Also you could always try another splitters to see if crash persists.

sorry I forgot the logs ... here they are.
Running Mediaportal 1.13 (final) on Win7 64bit

Reproducing is simple. Mux a HVEC video + AAC Audio File with the latest mkv-toolnix GUI (Win) into a new .mkv file.
Do the same with the latest mp4box into a .mp4 file.
Playback these files with Mediaportal - from the Video section

The .mp4 will do fine. Matroska crashes the app.

PS: I tried the Haali Media Splitter. Now the MP app. will not crash but is unable to playback any HEVC material ...

Thank you for the log files

As you can see from the Windows application event log, the source of the crash is nvcuvid.dll:

nvcuvid.dll is not part of MediaPortal, so this issue seems most likely to be related to the splitter and/or codecs that you have configured MP to use. On that point: I see you are using the LAV video codec. Have you configured LAV to use" NVidia CUVID" for "hardware acceleration" (DXVA), or enabled "hardware/GPU deinterlacing"? If yes, to me that seems the most likely source of the crash. I would suggest to try a different option (eg. DXVA2 (native)).

[edit: It might be helpful to provide a screenshot showing your LAV video codec settings.]

moreover, your GeForce GT 610 doesn't support hardware acceleration for HEVC, so don't expect it to work over GPU.
And the author ov LAV filters recently said, that nVidia broke something in their last drivers (since October 2015?) concerning CUDA so that it doesn't work flawlessly anymore. He adviced to use DXVA Native or CopyBack

Well ... "if so" ...

The playback of the .mkv works perfectly when using MPC-HC.
And the same Video data - but in a .mp4 container - also plays fine.

True, HW-acceleration is enabled in LAV config, but still this looks like an Splitter problem rather than a decoder issue

The playback of the .mkv works perfectly when using MPC-HC.

Doesn't MPC-HC normally use it's own splitter and/or built in codecs?
If yes, that's an obvious difference that could explain the difference in results.
...so if the MPC-HC configuration works, another way to solve the problem (in addition to changing your LAV config) could be to configure MP to use the same splitter and/or codecs as MPC-HC.

And the same Video data - but in a .mp4 container - also plays fine.

Yes, it's possible that the LAV splitter has a problem with certain MKV files... though I would not have thought that any splitter would need nvcuvid.dll.

Could be nice to have a sample to see if we can reproduce it too

MPC-HC uses as default it's own LAV filter (ver. 0.66).

obviously you would need to have same driver version (and maybe even same hardware). Despite @may24 hasn't yet posted settings ov LAV video decoder.
