Hi!
Attached patch fixes teletext detection for a sample that was uploaded by a
user in the thread "Which command line can do dvb_teletext from ts to mp4"
on the user mailing list:
http://we.tl/Zg2yq1H136
I am glad if somebody could explain how this should be done differently
for the given stream.
Please comment, Carl Eugen
