Please do not top-post here!
Your original command line was:
> ffmpeg -i output.ts -vn -an -f rawvideo -copyinkf
> -scodec copy teletext.dat
-scodec copy ensures that the teletext is not decoded
but put (unchanged) into a new file. I believe there
could be (hypothetically) software that is able to
read the file, FFmpeg is not.
If you want to decode the teletext (subtitle) stream
you have to know the page (FFmpeg does not autodetect
it), and you need FFmpeg compiled with libzvbi support.
You then can transcode the teletext subtitles into the
subtitle format you need.
