On Mac the ffmpegx tool supports 2 audio tracks. Maybe worth checking out? http://www.ffmpegx.com/index.html - Creates AVI or MPG files with two audio tracks. - *Supports subtitles* in VobSub, SubRip, MicroDVD, SubViewer, Sami, VPlayer, RT, SSA, AQTitle, JACOsub and MPsubt formats On Tue, Feb 2, 2010 at 5:40 PM, Silvia Pfeiffer <silvia at silvia-pfeiffer.de>wrote: > On Wed,

DVD has the UI and the low level meta information. The API you propose is the glue between the 2. It also has practical content. Could a DVD like UI be implemented on top of your API? It may need more exploration features? Could your API be used on DVD content asis? Do your APIs have 1:1 relationship with meta information in the files? multiple languages requires language codes match up. Your

DVD is a subpart of MPEG: http://www.mpucoder.com/DVD/vobov.html, http://dvd.sourceforge.net/dvdinfo/dvdmpeg.html . Uses the same functionality for tracks, iiuc.

...ds some music and makes a stereo mix. He then encodes this as a stereo ogg file. He sends it to musican (b) who then records his contribution. It would be nice if we could then merge the two and so on. Ideally of course, with 255 tracks available, then we could see this as a container format for multitrack music. Wouldn't it be nice to have an application where each (mono) track decoded, panned to L+R and has a level set (easy in the decoder). Of course, we cannot render to raw data and re-encode as this is bound to introduce (more) artefacts. SO, does anyone have any thoughts about how to copy...

What would the creation of a AVI or MPG with 2 audio tracks tell me that I don't know yet? I can just use normal ffmpeg for that - ffmpegx is just a GUI transcoding tool based on ffmpeg and the latest ffmpegx release is more than 2 years old. Anyway, I did look at the AVI spec after this email (http://msdn.microsoft.com/en-us/library/dd318183%28VS.85%29.aspx) and found that while each track

...Hi, Silvia. I studied your multi-track work when I was working on ALingA. It was a valuable guide. No, libogg++ tries to be agnostic about codecs.

hello all, I just joined the development team for audacity, a corss platform open source multitrack audio editor. I would like to add support for importing and exporting files in FLAC format. I was wondering if any of you could point me to some documentation about using libflac to add FLAC support to other programs? thanks, jason jason@pepas.com ps - sorry i am not subscribed to the list, so...
