[Cin] QSV profile debuggin thread

[Andrew Randrianasulu]

ok, so we have

profile: av1 main; level: 30
and pix fmt nv12

you can try to break this *working* line by inserting various -profile (and
-level?) params

OR

you can try to modify line in bin/ffmpeg/encode.opts and see error cingg
based qsv encode produces.
