demuxing teletext subtitles

[heideki]

When I demux my DVB-S recorded TS-files with Project X the teletext subtitles has no timings. He claims the first and last packet times to be identical for the intire teletext, (ex Teletext PTS: first packet 08:58:07.367, last packet 08:58:07.367). When I open the extracted subtitle file I've got all the sentences but they all start at 0 and ends at 0. I think if I manage to change the last packet timecode when i demux the .ts-file it would solve the problem because when I watch the movie on my Dreambox on which I recorded the movie the subtitles work. This problem occur when recording from some channels with teletext subtitles. So is there any way to change the last packet timecode?

that is a 'faked' value (taken from video).
the latest rel. should tell you this somewhere above in the Log (IIRC).

that, alone, wouldn't work, because there is NO timecode at all.
but, in all actual releases, there is an option at <subtitles> to "re-build" the missing PTS from an included MpgAudio in a TS,mpg,vdr etc.
so, working with a TS from DB (with MpgVid, MpgAud, TTX) solve that prob.

with the 'stolen' PTS, you'll reach an accuracy of the text insertion timing of about (max.) 1 second, but usually that's less (better than expected).
