[FFmpeg-devel] Captions SCC

[Marth64]

Hi, agreed to move on from this thread.
One parting thought, for future readers -- the RCWT muxer in FFmpeg
preserves the A/53 Part 4 coding intact from decoders which provide it
as side data.

So, it would include EIA608 and CEA708 (DTVCC) pairs since the A/53
Part 4 frames from the SEI messages (which packs 2 EIA608 fields and
CEA708) are left alone.

In the future if there is a CEA708 decoder one can do processing from the RCWT.
