I think there should perhaps be a better solution to what libavformat traditionally tried to do. On the command line, ffprobe could be used to dump exact and detailed information about decoded frames. On the ffmpeg.c level, it actually should decode a frame, which would solve a bunch of problems, including those that can't be solved by the traditional libavformat model. (Such as changing parameters due to hardware decoding.) av_dump_format() should be constrained to demuxer information. (Just change its output.) _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
