Description

I am trying to add external subtitles to a dvd movie and noticed that it works
only for the first part of the movie, since mplayer switches to the beginning of
subtitles in the midle of the movie.
I turned the OSD state to seek+timer (key o) and noticed that once mplayer
reaches the moment 01:05:26/02:02:53 it starts counting from zero (00:00:00)
again which in turn starts displaying subtitles from the beginning, although it
does not have any other bad effect on the movie.
The movie I tested was: "Open Your Eyes" Scandinavian edition (PAL) mastered by
"Dan Film A/S".
I also tested this overwrap on "Dune" (PAL) mastered by "Scanbox Entertainment"
and the time-reset moment was a bit different: 01:08:34/02:19:45.
I could not replicate this on shorter movies like "The Ring" by Dreamworks
(American, not Japanese version), actual length 1:51:05 (mplayer detected
strangely as 01:26:51).
So it seems that time-wrap happens for movies longer than 2 hours.
Could you please comment what can be wrong?

I am using unoficial mplayer Debian package from
ftp://ftp.nerim.net/debian-marillat/ unstable main
It identifies itself as:
MPlayer dev-CVS--3.3.4 (C) 2000-2004 MPlayer Team
CPU: Intel Pentium 4/Xeon/Celeron Foster 2660 MHz (Family: 8, Stepping: 7)

  • Could you explain step by step, how you tried to add external subtitles?
  • Could you send as attachements, ifo_dump of your dvd's (ifo_dump can be found

in ogle : ifo_dump <path to dvd>/VIDEO_TS/ 1 > dump.txt)

Right now I am on vacations, and don't have "Open Your Eyes" DVD with me, so
here is ifo dump from Dune DVD.
I add subtitles with option -sub, but subtitles work perfectly if the time
offset is correct.

I think this is a known limitation. On several DVDs the timecodes are simply
reset to 0 at some point (sometimes even more than once). MPlayer doesn't cope
well with that. Don't expect a fix for this soon.
