I believe MXF closed captions work similarly to Transport Stream CC content: Closed Caption is separated from video, and is present in a different track. I don't have a sample here, but according to this post <https://ffmpeg.zeranoe.com/forum/viewtopic.php?t=2406>, CC appears as a SMPTE 436M data track in MXF content. Aside from that, this page from Intel <https://software.intel.com/en-us/blogs/2014/08/18/how-to-add-closed-caption-messages-in-avc-and-mpeg2-streams> that describes a procedure, along with the code needed, to insert and display CC for H.264 using SEI messages; or MPEG-2 with user data. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
