I don't think there is any precedent for "profile" being mandatory for a decoder to work, so that might be iffy. Decoders usually set profile, don't require it. ie. from the docs: * - decoding: Set by libavcodec. There is plenty precedent for using "codec_tag" however, so that may be a better choice - and can hold the tag from the "container" as-is as well. - Hendrik _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
