Comment (by Balling):

 It is not OP but Kieran that claimes this libav is not affected.

 There is no libav anymore or at least no real development there. Most of
 patches from libav are in ffmpeg anyways.

 Conversion from 10 bit to 8 is indeed a simple shift. Just as back. If you
 go from RGB you are supposed to be precise though, there it IS NOT a
 simple shift.

 Oh, and also dither should be turned off by player too then.
