Hi,
Looking at the posts on Ubuntu, you're trying to decode an MPEG-4 ASP file:
Stream #0:0: Video: mpeg4 (Advanced Simple Profile) ...
Relevant FFmpeg output:
[mpeg4 @ 0x55f6e933f600] No support for codec mpeg4 profile 15.
[mpeg4 @ 0x55f6e933f600] Failed setup for format vaapi_vld: hwaccel
initialisation returned error.
To play these files using VA-API you need the
"VAProfileMPEG4AdvancedSimple" profile, but the output of vainfo says
your GPU doesn't support this. The FFmpeg error above also states this
(profile 15 corresponds to MPEG-4 ASP). While I'm not certain, after
looking on the Internet a bit I can't find any evidence that any Intel
GPU has ever supported hardware decode for MPEG-4 Part 2 encoded video.
