In this patchset are improvements for Closed Captions. This set overrides
the 3 patches I sent in the past few days, hence the v3 moniker.
Feedback should be addressed. Details about each change is in the commit.
Narrative:
(1) First, fix the MPEG-2 decoder so it does not try to overlap different
CC streams when content has mixed CC formats
(2) Fix invalid ASS tags produced by ccaption_dec, as well as the tests
(3) Fix leading padding produced by ccaption_dec (ignore leading NBSP)
(4) Correct wrong documentation on rcwtenc
(5) Add a RCWT demuxer. Now, one can fully mux/demux extracted
CCs in a bit-exact way from both ffmpeg and ccextractor.
The added benefit is this allows for easy archival of CCs
for later processing.
(6) Fix an unused include in SCC demuxer
FATE tests pass.
There is still more to do, I will slowly work on this.
Thank you,
