Hi!
Attached patch allows to use -f framecrc to check r10k -> gbrp10 ffv1 ->
r10k roundtrips: The decoder currently writes incorrect lsb for blue that
are different for the input and output files. This does not affect the 10
significant bits and therefore the ffv1 files are not affected, only the
rgb48 framechecks are wrong.
Please comment, Carl Eugen
