How can I do this ? Haven't tried, but Ogg Video Tools from http://dev.streamnik.de/files.html seems to have an oggCat tool for concatenating ogg files.

I'm not the most educated in video/audio matters to advise here, but I know that if you use ffmpeg and specify '-acodec copy' it will do just that with the raw data. I know you can use ffmpeg with streams, so some clever use of pipes may be required for your application. Perhaps someone more knowledgeable can chime in here. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
