I'd like to get the change reviewed so I can determine whether I need to make any other changes. This change basically allows 'ffmpeg -i blah.mkv foo.mkv ; ffprobe foo.mkv' to show that foo.mkv has the same SAR and DAR as blah.mkv when blah.mkv contains stereo content. Without this patch the SAR & DAR get smaller based on whichever dimension is halved by the stereo layout. Hope this helps, Aaron _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
