Thanks a lot.
Is that a rhetorical question? ;-) If not:
If you look at this doc page (or some other related google hit):
https://www.ffmpeg.org/ffmpeg-all.html
and search for teletext, the first thing you will find is the
desciption of the libzvbi-teletext decoder.
https://www.ffmpeg.org/ffmpeg-all.html#libzvbi_002dteletext
It doesn't say right there, but somewhere where ffmpeg's options system
is described, that decoder options are *input* options and belong
before the corresponding input.
The "-fix_sub_duration" is Carl Eugen's special discovery for you. ;-)
He understood the (apparently common) symptom you were describing.
I guess we could add an example to the docs, I remember others wanting the
same thing and struggling a bit figuring out on their own.

Marton
