Comment (by reimar):

 I don't think I can see what you mean with the colors, but these are
 10-bit formats, so there is a chance something is going wrong on the
 conversion to 8 bit.
 Or actually, more likely the wrong colour transformation matrix is used.
 If you have a current MPlayer version around, you can try -vo
 gl:colorspace=0..3 to see what the different ones look like (probably lots
 of other programs that can do that as well, but my own code is easiest for
 me to remember how to use :-) ).
 Due to the problem with the AVCI50 header I'd rather not want to use them
 directly, but instead properly generate the SPS/PPS. Unfortunately that's
 a bit more work and I don't know when I'll have time for that.
