Sorry that I did not (yet) test myself.

What is the default behaviour if the file 
contains a teletext stream but no subtitles?
What if there is a teletext stream containing 
one subtitle page?
What happens if the teletext stream contains 
multiple subtitle pages?
Is it possible to use non-subtitle pages as 
subtitles?

Or in other words: Is one FFmpeg subtitle 
stream provided for all pages plus one 
stream for each subtitle page?

Or is this not a good idea?
