Comment (by nicol):
I want to demux arib subtitles form TS(.ts or .m2ts) file, such as
Caption2Ass_PCR(.ts only), using ffmpeg.
https://github.com/maki-rxrz/Caption2Ass_PCR
Upload sample file. https://www.datafilehost.com/d/bc19159f
Stream #0:2 is arib subtitles data, but this data is binary data. I want
to text subtitles data.
ffmpeg -i input.ts -map 0:2 -c copy -f data output.bin
