I am trying to convert files like the following:
It appears to be similar to other h264 videos I’ve gotten that have EIA-608 CC.
Yet normally I don't get any errors at all in CCExtractor but this video and others from the site give me:
"Warning: Probably loss of CC data, unsaved buffer being rewritten, trailing end might get lost"
I tried looking up this error but I oddly only get results from the actual CCExtractor, not anyone asking about the error.
I also tried:
which worked great other than sayingCode:ffmpeg -f lavfi -i movie=test.mp4[out+subcc] -map 0:1 output.srt
"[Parsed_movie_0 @ 0000020fc3a0e080] EOF timestamp not reliable" but Google results say normally that can be ignored.
Yet if I try and tell ffmpeg to encode using the produced srt, ffmpeg randomly stops and exits after a few seconds.

Actually I think I figured it out.
I noticed if you look at the ffmpeg produced SRT you see tags like <font> and similar.
I thought maybe that's throwing things off as other mp4's from CCExtractor and just SRTs I got offline never had tags like that.
So I told ffmpeg just make a "VTT" out of the subtitles and then right after it was happy to encode me a new file with the subtitles.
