theora - Oct 2009 - Join two theora video files

-----BEGIN PGP SIGNED MESSAGE-----

Hi all:

I have a question which, maybe, could go to the Theora FAQ.

How can I join two theora video files in one without recompressing them?
Can I just join them one after the other, like with Ogg/Vorbis?

I've created a front-end for Thusnelda and want to offer extra features
not yet in other software. My idea is to do multithread compression by
compressing 1/n of the length of the original video in each core, and
join all the videos after the process. Does FFMPEG2THEORA support
fine-grained start/stop points, or will I have to tune it?

Thanks.

Yes, this is possible under some conditions:
1) Every part must begin with a keyframe
2) Every part must be equal in it's encoder configuration

However you have to care for the process to mux the created video packet into an
ogg stream/file.
