Hi,

I first saw this problem in Atlantis and it's still present in 9.04.1: the subtitle streams in VOB files do not always display, even though XBMC reports that they exist.

When the subs do display correctly it is when dialog (and subs) start immediately, such as a TV show that starts with "Previously on ...". When a movie starts, and there's a couple of minutes of credits rolling before the first dialog, the subs do not display. However, the subs & audio menu shows that a subtitle stream is present.

Perhaps if no subtitle text is present with time code 0 then no further check is made? I don't know.

Anyone else seen this? I searched and found a lot of subtitle problems involving external files but not VOB streams.

Cheers,
N

vob files are not meant to be played separate from their corresponding .ifo file....

having said that, a log file would help

I have no problems with subtitles in .vob files and i don't use the .ifo or any of the other files associated with dvds i rip the entire film to one .vob file and as yet have not found a video player that wont play them Smile

though i do have to pick the subtitles manualy but that's no big deal

pure luck + as you say, you have to pick manually.

It's hardly pure luck at all or did you mean something else altogether

the ifo files contain all meta information about audio, video (chapters, angles) and subtitle streams. the fact that you can playback the .vob is "pure luck" in the sense that you have broken the dvd file structure doing your nasties, and it is certainly not your doing that it works.

What the ..... do you mean doing my nasties it most certainly is better than the converting to divx etc and it's also nothing to do with xbmc either the fact it plays is down to the fact it's basicaly a mpeg2 file. Stare

Thank you all. I have a log snippet to post here.

I should add that my vob files are renamed as .mpg (if that makes any difference) and do not have accompanying metadata files. All such files are ripped from DVDs with the same software. Often a TV show with subtitle problems was ripped within the same batch job, with identical rip settings, as another episode that plays fine. Some work, some don't.

I can watch the same files on a network DVD player which has no trouble showing the subtitle streams with no metadata support. This leads me to think it's down to the particular treatment used by XBMC (I use the Mac version).

Looking at the log, Segment 2 logs a TV episode where the subs play well. Segment 1 logs another episode, ripped from the same disc with the same settings. The log shows no subtitle stream found, even though there is one and the XBMC subtitle and audio menu shows a subtitle stream as present.

I've included the before and after keypress events because I've noticed an error message immediately after the video with the non-showing subs. There are 23 of these unknown button events, one after the other (I've deleted some to save space), followed by the normal 'Play' event used to invoke the menu as in segment 2.
