There is no "SCC" encoder in ffmpeg, and if there was one, it wouldn't help much because the CC data needs to get into the video frames - so that it exists as input to the video encoder. > For the same reason, it is also not possible to add CCs at the muxer level. It always requires video encoding because the data needs to get into the video stream itself, so there's no way to get data from an SCC file into a video stream currently. > > The only way in the ffmpeg architecture to get CC data encoded would be at the filtering level. The Subtitle Filtering patchset that I have submitted a while ago has a "splitcc" filter which has video as input and a video plus a subtitle pin/pad at the output side. > What would be needed is a reverse pendant like a "mergecc" filter with video and subtitles input - plus a CEA-608/708 encoder. > > softworkz > Hi softworkz, Sorry about that, The response is indeed from AI. I thought this question was enough for AI to answer, I will pay attention to it next time. Thank you for pointing it out.
