You cannot rely on that. Especially since noone knows what format the decoder is going to use. avformat will tell you its YUV420P10, not P010. A user who doesn't use avformat at all and only feed avcodec will likely not set avctx->format at all, since basically nothing else needs it. A decoder has to figure out the pixel format by itself. - Hendrik _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
