Ah, thanks. Then I guess only way to get vaapi accel for av1 is to comment
line in ffmpeg/decode.opts

May be indication of decoder itself a bit broken in this case? Anyway, may
be situation will be a bit better with some async patches floating at mesa
and ffmpeg mail list/patch tracker .... If you think this is generic bug in
AMD's vaapi driver you can try to enter it at mesa's bugtracker. May be
this time our name/program will stick for at least some devs .....
