I'm against polluting AVCodecContext with more random fields, and get_format is fixed API/ABI, we can't change that very easily. In general, this is per-frame metadata, which can appear or change with any given frame, without get_format being invoked again. You should probably just be able to have your output react to that once it receives it. - Hendrik _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
