OGM & Subtitle problem

[Eric B]

Hi,

I've got a film with 2 audio tracks in an OGM file. I would like to add subtitle to it. Is there any easy method to do that ?

I try to demux the in.ogm file with OGMDemuxer found here (http://cyrius.bunkus.org) which gave me the avi file and the 2 ogg vorbis audio files.
Then, I've used OggMux (and also OggMuxer) to mux these 3 files with 2 SRT file to have the out.ogm. Muxing works fine, but I can't read the out.ogm !
Bsplayer (b493) crashs, TCMP RC1 read only audio track without image. Only WMP6.4 (& MediaPlayerClassic) can read this out.ogm, but with wrong proportions. The subtitles are cropped by the player. Why ?

I've re-install Ogg DirectShow 9.9.9.5 & SubTitDS 1.4. My other ogm files are well read by all players, but after I try the out.ogm, they crash !

I also demux the out.ogm, and I've got the same files as in input of OggMux, so that's not the problem.

Can anybody help me ?

Try VirtualDubMOD (http://virtualdubmod.sourceforge.net/).

Iv'e tried VirtualDubMod. Works fine, but give me the same out.ogm as I had before (with the advantage of no need to demux first). This mod looks very good. Can it definetly replace Virtualdub AND Nandub AND OggMux in one software ?

With MPClassic, I've changed the options of SubtiDS to have the same video proportion as the avi file. But now, the subtitles are on the video. Is it possible to keep these outside ?

Dunno why but BSPlayer often has problems with OGM and subtitles ...
The crop problem you describe is (IIRC) due to SubtiDS. You can try to replace the ratio (SubtiDS filter properties) by using the image size of your video (this may help).

There are also problems between SubtiDS and DVobSub (generally enabling both isn't a good idea).


If you don't need Nandub for SBC then VirtualDubMod can replace it (we borrowed Nandub code for handling a second audio stream in AVI and open AC3/MP3 for AVI too). Generally speaking it could also replace VirtualDub (but remember it is in development so maybe there could be bugs due to the changes we made ;)).
As for OggMux I can't tell. OggMux uses OggDS (DirectShow filters) while VirtualDubMod doesn't. So both programs use 2 (different) ways of muxing data in OGM files. I can't tell you if this make a big difference for the resulting file (size difference, synch problems, ...), nor if one is better than the other because they are different.
