[wayland][nvidia-drm] Desktop freezes when playing video via mpv using nvdec

Graphics / Linux Linux

demo-4k|video

14

Unfortunately, I am still not able to preproduce issue locally.
mpv is playing shared video using nvdec without any issue.

15

Obviously our hardware is completely different so you can’t reproduce the issue

16

@fiepi
Can you please test with driver 520.56.06 and share test results.

17

Previously I had an external 4k monitor, and now I don’t have such a monitor around, so now I’m testing on the built-in screen, no crashes.
Kernel: 6.0.6
Driver: 520.56.06

So, you are seeing this error message again on the built-in screen now ?

20

Yes, but these kernel panics did not cause system crashes and desktop freezes, which is an improvement over before

Can you please try with flag --hwdec=nvdec. There are no failures for hardware decoding or mpv with --hwdec=nvdec on my test system.

24

mpv 0.35.0 work now
Release v0.35.0 · mpv-player/mpv (github.com)

25

@amrits The problem is with interop between NVDEC and EGL. You need to have nvidia-vaapi-driver installed. See [525.53] mpv does not work with NVDEC and cuEGLStreamProducerConnect returns error 801 on 525.53 driver.

26

@fiepi
Can we close bug if issue if fixed at your end with mpv 0.35.0

@Lastique
Thanks for the pointer.

27

@amrits I tried mpv 0.35. Apparently, the official released binary is not compiled with NVDEC as it doesn’t recognize hwdec=nvdec and decodes video in software. At least, that’s the case on X11. If @fiepi tested that binary, I don’t think he actually tested the problem. I did not compile mpv from source, so I cannot tell if it fixes it. But given the other threads I pointed to earlier, and that e.g. Firefox also doesn’t work, I doubt it.

Ok, then ArchLinux packages were built with NVDEC. Thanks for clarifying.

@fiepi
If everything works at your end, shall we close this thread ?

yes, close it
