Description
I will upload a sample with two teletext subtitle streams (on pages 777 and 778). They can be viewed with the following MPlayer command lines (use "X" and "Q" to switch to the appropriate subtitle pages):
$ mplayer teletextsubtitles.ts -demuxer mpegts -sid 106
$ mplayer teletextsubtitles.ts -demuxer lavf -sid 0
FFmpeg cannot decode the subtitles.
$ ffmpeg -i teletextsubtitles.ts
