[FFmpeg-user] dvb_teletext -> .srt fails?

Fri Jan 15 22:46:42 CET 2016 

similar to https://lists.ffmpeg.org/pipermail/ffmpeg-user/2015-June/027029.html
and

https://trac.ffmpeg.org/ticket/3025

My "quest" is to convert an dvb_teletext stream to some human readable
(ex: .srt) format.

Ex: using this file:

https://trac.ffmpeg.org/attachment/ticket/3025/sbs.2.5M.ts

I don't seem to be having much luck (DVBT stream).  Any feedback welcome :)
