Except some macroblocks which used DPCM were not decodable for the reasons I described previously (impossible to fit this into mpegvideo.c). I will look at this again over the Christmas holidays.

Is the rgb output correct? It looks as if seen through a strange colour filter, do you think this is intended?

The unstable ABI period is still open, for that matter, so if you or anyone else feels like giving it a try then there's still a couple weeks to remove it as originally scheduled. Otherwise, it will be removed next year or so alongside AVStream->codec. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
