[FFmpeg-devel] [PATCH] Add A53 closed captions to mpeg picture header.

If AV_FRAME_DATA_A53_CC "user data" is available, encode it into the mpeg
picture header.

This follows the spec in section 6.2.3 of
http://atsc.org/wp-content/uploads/2015/03/a_53-Part-4-2009.pdf

I am working on gstreamer side, to inject the information into the ffmpeg
side data, and have it generally working.

It would also be trivial to add "AV_FRAME_DATA_A53_BAR", but I don't
currently have a way to test that.
