OggMux Features

[Defiler]

If I could do these things myself, I would.
Since I can't, I'll mention them here. Heh.
I'd like to have better control over exactly where my videos are split. Only sheer luck would cause there to be a convenient scene change at exactly 700MB..
How hard would it be to modify OggMux to be able to split at a chapter break? Even if you weren't coming from a DVD source, you could easily add your own chapter break at the exact point you wanted, then mux.

Additionally, (and less likely) it would be nice if OggMux had some features geared toward modifying existing OGM files.
For example: Changing chapter names.. extracting the chapter list.. Adding and removing audio tracks, etc.
My least favorite OGM characteristic is that they are "set in stone" once created. I know we're just waiting on an "OggDub" application, but having some minor tweaking abilities before then would be nice.

There's some problems with the things you mention, and that's why I need to work with Tobias to make them possible:

Well, there is always a scene change around 700 MB. At least in my implementation I stop muxing at ~700 MB, rewind 2 minutes and search for the nearest keyframe towards 700MB.

The splitting should be keyframe accurate, but somehow it isn't, and that's where work within the filters has to be done.

Changing chapters:
If you split the stream with the OggSplitter in graphedit, take a look afterwards into the files: they still contain this information. There is no way to "clear" them, and editing doesn't work either (believe me, I tried).

I'll look into writing a demuxer since people don't stop asking about this. But it won't be a nice app, it'll definatly suck :)

And the last question, sorry, I don't have a paypal account, but I appreciate the gesture :)

Regards,

Thanks for the swift reply.
It seems there is no perfect format, eh?
The things you mentioned, along with the incompatibility between DVobSub and the OGM subtitle filter.. Ugh.
If I switch back to AVI, I'll miss the instant seeking and chapter support.
Now I just need a web browser with time travel support, so I can go to Doom9.org circa 2004 for the latest versions of the tools and filters.

when the Vorbis audio and mpeg4 video are of different lengths ogg mux does not truncate at the shortest of either the Audio or the video (same thing happens with graphedit).

I have experienced this problem several times while trying to make music clips...especially when the audio track is longer than the video.

Is there a way to solve this? (Without having to make sure the A+V are the same length)
