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.
