Interesting, so av1 does not decode in hw in our case ... something to
investigate, but I have no relevant hardware ...

hm, ah, second error! Was it 10bit hevc by the way?

I think appimage may have outdated libva inside it, so course of action was
to unpack it and delete this library ....

Well, finally it works :) But not for us .... I'll try to add a bit more
debug at least temporarily

Thanks for testing!
