Hi Enrico,

I have found your message from 2012 and I would like to be sure you could
extract subtitles from the teletext because I'm trying to do exactly that
but I'm unable to do so.
The file is created but is empty.

gst-launch-0.10 filesrc location=filename.ts  ! mpegtsdemux
program-number=811 name=demux demux.private_0811 ! teletextdec page=887
subtitles-mode= "true" subtitles-template="%s\n" ! 'text/plain' ! filesink
location=teletext.txt

I'm using the pipeline described above. The filename.ts was recorded from a
dvb and the channel is on the program-number 811 and the subtitles are at
the 887 teletext page.

Thank you in advance,
Nuno Martins
