I've read issue 1233 and looks like the problem is with him not
initializing codec properly - you should set width and height to
real values before calling avcodec_open(), otherwise it's GIGO.

I will gladly accept a patch implementing decoding sequence header for VC-1
before h263_decode_init() when dimensions are not set, but not your hack.
