Hi all, I'm getting mired in conflicting and dated information, so I think I need to ask this of live humans... :-)
I'm essentially trying to create an Ogg file that works like DVD video does. In particular, in addition to the Theora video stream, there will be multiple audio "tracks" (By "track", I mean a collection of channels to be played all at once, but only one track should be played at a time). Each track may have a number of channels, e.g.: 1 for mono, 2 for stereo, 6 for 5.1 surround sound. The tracks can be FLAC or Vorbis or a mixture of the two. So, for example, I might have: Track 1 - English 5.1 Surround (6 channels) Track 2 - English Stereo (2 channels) Track 3 - French Mono (1 channel) Track 4 - Spanish Stereo (2 channels) I have just (finally!) found 5.1 channel assignments for FLAC and Vorbis, and wouldn't-you-know, they disagree: Vorbis FLAC L L R R LS LFE RS LS LFE RS Fortunately, stereo and mono seem to be fairly tame. The tracks can be FLAC or Vorbis or a mixture of the two. Anybody know what the state of the art is now? Right now, I'm thinking, the "best practice" is going to be to multiplex _channels_ within the audio codec (i.e. FLAC or Vorbis), while each _track_ is a separate audio stream in the Ogg file. Does that make sense? Do players actually support this? And What tools exist to merge separate single-channel FLAC files into a multichannel FLAC? I already know of the ogg-tools and oggz-tools utilities for manipulating the Ogg streams, so I think I have that part covered. Thanks!
