- Bug fix on inter MCBPC table for inter+q.
- H.263/H.263+ decoder now knows GOB start codes. - H.263/H.263+ decoder now returns the size of the stream on the first call. - Added show_bits() functions to see the buffer without loosing the bits. - TODO: H.263v1 UMV parsing is buggy. Originally committed as revision 204 to svn://svn.ffmpeg.org/ffmpeg/trunk
