Fixes: - i/p/b_decode_mbs functions now checks the proper values (from bitplane). I didn't find it very clear, but it seems "raw" = "to read at the MB layer". I used a structure, but we could spare that indirection and add a flag in the VC9Context for each array. - Properly decode (or so I think) the CBPCY (as it is predicted) - many more things patch by anonymous Originally committed as revision 3882 to svn://svn.ffmpeg.org/ffmpeg/trunk
