Failed to decode mpeg4 (x264) video

[choryuidentify]

Hello!

I'm using Orange Pi Plus 2 with Arch Linux (mainline 5.3.7-1-ARCH).
I've install libva-v4l2-request-git package.
and run vainfo, it display correct information.

vainfo: VA-API version: 1.5 (libva 2.5.0)
vainfo: Driver version: v4l2-request
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            : VAEntrypointVLD
      VAProfileMPEG2Main              : VAEntrypointVLD
      VAProfileH264Main               : VAEntrypointVLD
      VAProfileH264High               : VAEntrypointVLD
      VAProfileH264ConstrainedBaseline: VAEntrypointVLD
      VAProfileH264MultiviewHigh      : VAEntrypointVLD
      VAProfileH264StereoHigh         : VAEntrypointVLD

so, I've trying decode MPEG4 video using VLC. Video is this file
and got this error (verbose log)

main debug: looking for hw decoder module matching "vaapi": 3 candidates
vaapi_drm error: profile(3) is not supported
main debug: no hw decoder modules matched

and I trying v4l2-request-test, mpeg2 is ok (log), but h264 is failed (log)

h264 preset is disabled some unknown reason, so I've turn on h264 using export CFLAGS=-DV4L2_PIX_FMT_H264_SLICE=1

How can I resolve this problem?
and It's have schedule for support GStreamer? I'm trying to porting OpenAuto to Sunxi boards.
Thanks!

I have a similar setup (Orange Pi PC running on 5.3.8-1-ARCH) with the same libva-v4l2-request-git package package installed but a different error.

$ vainfo
vainfo: VA-API version: 1.5 (libva 2.5.0)
vainfo: Driver version: v4l2-request
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            : VAEntrypointVLD
      VAProfileMPEG2Main              : VAEntrypointVLD
      VAProfileH264Main               : VAEntrypointVLD
      VAProfileH264High               : VAEntrypointVLD
      VAProfileH264ConstrainedBaseline: VAEntrypointVLD
      VAProfileH264MultiviewHigh      : VAEntrypointVLD
      VAProfileH264StereoHigh         : VAEntrypointVLD

But when running v4l2-request-test I get an error "Unable to open DRM node: No such file or directory".

@luusl did you add 'video' group on your user account?

[luusl]

@choryuidentify Yes, I'm in the video group. Same result when running with sudo.

OK, the problem with me was apparently that I had an X server running, after quitting it I ran into the same problem as @choryuidentify.
