Comment (by pdr0):
extractplanes=y is probably more "elegant" than scale with format
conversion . The 10bit Y plane is equivalent to the gray10 (just
discarding CbCr planes)
{{{
ffmpeg -i test3.mp4 -i test.mkv -lavfi
"[0:v]extractplanes=y,settb=1/AVTB,setpts=PTS-
STARTPTS[main];[1:v]settb=1/AVTB,setpts=PTS-STARTPTS[ref];[main][ref]psnr"
-f null -
}}}
PSNR y:inf average:inf min:inf max:inf
{{{
ffplay -vf extractplanes=y -i test3.mp4
}}}
