Hello all
Could you please tell me if and how Vorbis is used for the audio in
DivX?
Is it still encapsulated within ogg container format in DivX or does
DivX
contain raw Vorbis encoded packets?
Any clues or pointers would be helpful.
Thanks & regards

Preferred format for that is Ogg (OGM), though you could also use Matroska. There are also hacks to get Vorbis to work inside AVI, but you should stay away from them. -- < Jernej Simoncic ><><><><>< http://deepthought.ena.si/ > Nature will tell you a direct lie if she can. -- Darwin's Observation
I'm not sure about in an Ogg container right now. I know you _should_ be able to do it in the future. You can do vorbis and divx together in a .ogm file however. You can process the divx avi however you want. Take the source file (wav/ac3) and convert it using BeSweet (if you still want surround sound), oggenc, or oggdropxpd (if it isn't ac3). Then you can then mux the vorbis audio file and the divx avi (it just takes the video stream from an avi) using OggMux (http://oggmux.sourceforge.net/index.html) and Tobias' Directshow Filters (http://tobias.everwicked.com/). I have used vorbis in the this manner. I like it because Q -1 provides fine sound quality for most video/movie material and at a much lower bitrate than mp3 for that matter. Ogm will also do keyframe seeking which is much faster (although less accurate, but it usually doesn't matter) than normal seeking. Be advised though that this is not a popular topic here. I have gotten the impression that ogm is kind of a bastard container since eventually everything (audio or video) should be in a .ogg container. I think www.doom9.net has some tutorials on this actually.
