 An SCC Muxer was added with this commit:


 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
