Comment (by Andrew-R):
There are other bugs still open
https://trac.ffmpeg.org/ticket/3345
https://trac.ffmpeg.org/ticket/7978
I also tried to compare y4m files with vbindiff (console program) and they
surely differ :(
I also found suggestion by Paul (?) that input/output range must be always
set, explicitly. I wonder how to handle this in our cinelerra-GG, given
this data not always present at container/codec level, so we easily can
get unknown....

May be I should try dither=0 sws flag too
