/*
FFmpeg can "read" and/or "extract" subtitles from embedded subtitle tracks.

For instance, if you run ffmpeg -i <my_file> and you see something like:

    Stream #0:2: Subtitle: ssa (default)
or

    Stream #0:2[0x909](eng): Subtitle: dvb_teletext ([6][0][0][0] / 0x0006), 492x250
You can extract or convert those subtitles. To convert to srt from dvb_teletext.

ffmpeg -txt_format text -i input_file out.srt
Your FFmpeg needs to be configured with --enable-libzvbi for this to work, and results in something like this:

  Stream #0:17 -> #3:0 (dvb_teletext (libzvbi_teletextdec) -> subrip (srt))
vbi teletext is a format specification that allows for including text (characters) and a few basic images as metadata between video frames of a broadcast.
