Well it's a tricky situation with cabac which would be a shame to loose.
Currently I guess it's a bit strange advertising main/high - but then
others do without having mbaff support ....
As it stands with cabac on I can make (what I think is) a perfectly
legal stream with ffmpeg or gstreamer (ignoring current mesa issue).
... -c:v h264_vaapi -profile:v 77 -bf 0 ...
FWIW ffmpeg actually detects the lack of b-frame support, omitting -bf 0
from above will throw an error.
[h264_vaapi @ 0x3075aa0] B frames are not supported (0x1).
I guess that means that gstreamer could in theory do the same.
Looking at a ReLive sample shows it's flagged as main, has cabac
and doesn't have any b-frames.
