Comment 2 for bug 1991440

An update on the packaging of new versions: latest libva 2.16.0 is now published (at ppa:savoury1/ffmpeg4), and latest FFmpeg 5.1.2 built against that version is also available (at ppa:savoury1/ffmpeg5). Additionally, new builds of mpv 0.35~pre (pre-release of 0.35 from git source today, 3 Oct 2022) have just been completed at ppa:savoury1/mpv and these were naturally done with the new libva and FFmpeg versions.

Please upgrade to these new versions and test if you still have the issue with a missing symbol. If the error persists then there is likely nothing more I can do to fix it at the packaging level. In that case, perhaps you could report the issue upstream to the mpv devs [*] (include your GPU hardware info, proprietary AMD driver versions, etc, if you do that) to see if they might be able to help.
