Here's a question I have: My understanding is that OGG is a 'containter' format, allowing for multiple streams of multiple types, of which Vorbis is only one. My question is this: Is it feasable (and, considering licencing, leagal) to create an .ogg file that contains, say Indeo or Cinepak video? (In other words, use the ogg bitstream to store the data rather than .avi). Personally, I think this might be a fairly interesting way to learn to code for the ogg project: Implement pre-existing formats within ogg. Personally, I think a great example would be 'ogg wav,' which is exactly what it sounds like: .wav files stored inside an ogg bitstream. (I know I may have the terminology wrong, and actually /doing/ it would be a bit... redundant... stupid... waste of time... but it could serve to help educate some of us heathens about the robustness of ogg, and/or how to code for it.) On a similar train of thought, it would be great to have support for VP3 -- which as I understand it can be added to the ogg project (it's open-source, and I think the licence allows it...). Another example would be DivX or MPEG4. (ogg is a container, so licencing doesn't apply, right?!?) It'd be slick to have an .ogg file using DivX video and Vorbis audio. (I mention DivX and VP3 because they exist in a release-form now; I'm not ignoring Tarkin at all. I'm simply wondering if there are any technical (and, sadly, leagal) problems with DivX and/or VP3 inside an .ogg file. Basically, I see all these codecs that windows can use (and many of which are $free) and think it's a shame that they seem to be restricted to .AVI. <p><p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

The .txt file would be for lyrics, which don't work well in a vorbis comment. Maybe these questions should be on the development list; I don't know. But it would be nice to know how one is supposed to go about putting non-vorbis content into .ogg files. -- Greg Wooledge | "Truth belongs to everybody." greg@wooledge.org | - The Red Hot Chili Peppers http://wooledge.org/~greg/ | -------------- next part -------------- A non-text attachment was scrubbed...

Personally, I think this might be a fairly interesting wayYes, it is feasible since Ogg was designed with this sort of thing in mind. The legality is entirely determined the format you choose to embed in Ogg. That is to say, there are no licensing issues with Ogg (since it is BSD licensed), so the legal issues are going to come from the other format/codec. An example of a mixed format Ogg is the code which Jack wrote and placed in the ogg-tools module to produce Ogg Vorbis+MIDI files. There is an oggmerge program which puts the parts together and an omplay program which will play them if you are using very recent ALSA drivers. In that same module, you will find some of the code (I don't think it works) to do Ogg Vorbis+MNG. --- Stan Seibert <p><p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.
