Slightly unrelated question = with vaapi using mpeg2 do you get the
same result as vdpau or s/w?
Well MPEG2 actually defines that the resulting image doesn't need to
be 100% bit identical on all decoders. H.264 and others are way more
strict regarding this.
Do you also see actually visible artifacts as well?
In the vaapi case they are quite noticeable - too bad to be within some
sort of tolerance.
vdpau I wouldn't really notice without close inspection.
I am testing with mpv (git needed as release will default to s/w for
mpeg2 vaapi)
gstreamer omx hw dec produces the same artifacts as mpv vaapi.
(I have yet to test gstreamer vaapi on mpeg2 as I can't get it to work
with my samples - it works OK for vaapi + h264)
