[MPlayer-users] problem with vob subtitles on mplayer 1.0-pre3 - part 2

[Jean-Yves Simon]

Hello,

I have found a problem with mplayer 1.0-pre3 running on an intel p3
fedora core1, 2.6.0 kernel, gcc version 3.3.2 20031022 (Red Hat Linux
3.3.2-1)


On the 294 subtitle lines, 3 or 4 aren't read, i have only noticed this
with this dvd (all the anime episodes on it), the problem happens on the
vobs AND on the vobsubs.
When i tried xine with the vobs, it did read the "hidden" lines.

I've played with mplayer -v, it prints an output when a subtitle is
read, but it is simply not shown on the screen.


When looking to the .idx file, it seems there's a bogus? subline before
one that isn't read. or maybe it takes too much time to be printed?
for instance:
timestamp: 00:12:05:006, filepos: 00006e000 shown
timestamp: 00:12:07:606, filepos: 00006e800 shown
timestamp: 00:12:12:806, filepos: 00006f800 not shown (bogus?)
timestamp: 00:12:13:326, filepos: 000070000 not shown
timestamp: 00:12:18:526, filepos: 000070800 shown

is sub at 0:12:12 empty and/or bogus and/or taking too much time to
display?
then sub at 0:12:13 isn't shown, which is actually one that should be.


Another example from file -04: (when playing -ss 0:3:0)
timestamp: 00:03:06:286, filepos: 00000f800  shown
timestamp: 00:03:19:286, filepos: 000010000  shown
timestamp: 00:03:22:406, filepos: 000010800  NOT shown
timestamp: 00:03:26:046, filepos: 000011000  NOT shown
timestamp: 00:03:30:206, filepos: 000012000  NOT shown
timestamp: 00:03:33:326, filepos: 000012800  NOT shown
timestamp: 00:03:39:566, filepos: 000013000  NOT shown
timestamp: 00:03:42:686, filepos: 000013800  shown
timestamp: 00:03:46:846, filepos: 000014800  shown with 2 seconds
desync?





a 350KBytes vobsub file can be found on:
http://lethalwp.dyndns.org/~lethalwp/files/vobsub/trigun-002-vobsub.tgz

another one:
http://lethalwp.dyndns.org/~lethalwp/files/vobsub/trigun-04-vobsub.tgz
(where the subs have problems at sub number 21, at ~00:03:15, there are
about 6 or 7 sentences missing in less than 3 minutes)

one episode is approx 1,3GB, but since there are lots of subtitle
problems in the 4 first minutes, i could upload ~250MB, that should be
enough to see the problem on the vob





here is how to trigger the problem:
mplayer someavi.avi -vobsub trigun-02-fr -ss 0:12:01



you should read the lines:
--------
Bon, je vais faire un tour.

Autant se mettre au boulot
de garde du corps tout de suite.

*** MISSING LINE ***

Comme si je l'espio...

Je ne vois pas pourquoi vous dites ca.
--------


missing line (when extracted vobsub to pnm files, frame number 151),
should read:

J'ai conseille a Marrianne
de bien tirer ses rideaux.
