Comment:
An SCC Muxer was added with this commit:
[https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/036e12b225b2869861d1449534dec94bd491559e]
This command will now create a .scc file from source media containing
EIA-608 Caption Data in userdata
{{{
ffmpeg.exe -f lavfi -i movie="CC_TEST001.mpg[out+subcc]" -map 0:1 -c:s
copy T:\temp\output.scc
}}}
This provides creation of .scc from media containing captioning which is
what this ticket morphed into.
The original request still exists to provide ability to use a .scc file as
a source for inserting EIA-608 captioning as A/53 in MPEG-2 and x264 as
well as 436M Ancillary Data of MXF files
