Yes, that's an option. Setting all fields to undefined/unknown if it's not a keyframe and stop parsing altogether. Can a keyframe be contained within a superframe, for that matter? Or are those guaranteed to be standalone? _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
