cleanup
adding AVVideoFrame moving quality, pict_type, key_frame, qscale_table, ... to AVVideoFrame removing obsolete variables in AVCodecContext skiping of MBs in b frames correctly initalizing AVCodecContext picture buffer cleanup Originally committed as revision 1302 to svn://svn.ffmpeg.org/ffmpeg/trunk
