Invalid End-Timestamp of subtitle file

[martinr92]

Summary of the bug:
I'm trying to extract the subtitles (dvb_teletext) from a recorded tv movie.

The following command is used to achieve this:

./ffmpeg -v 9 -loglevel 99 -txt_format text -txt_page 150 -i Tatort-small.ts -y subtitle.srt

A new subtitle file is created and the texts are successfully extracted.
Also the start timestamp is correct, but not the end timestamp:

1
00:00:02,280 --> 1193:02:49,575
Sie sind purer Antisemitismus.

2
00:00:05,520 --> 1193:02:52,815
Auch der Spitzenkandidat
der Linken, Bartsch,

3
00:00:09,360 --> 1193:02:56,655
verurteilt die antisemitische Gewalt.

Where can I upload the file? I reduced the size already to 30MB (original was 4.5 GB). The FTP upload server (mentioned here https://ffmpeg.org/bugreports.html) seems not responding.

Use -fix_sub_duration. (Teletext is one of the formats where packets don't have a duration, but are ended by a later packet and this command makes ffmpeg actually use these later packets to fill in the duration of the earlier ones.)

Replying to mkver:

Use -fix_sub_duration.

Works perfectly. Thanks.
