Me again, this time not about patents but about wavelets. I've been doing some work on an image compression method which uses Haar wavelets plus VQ and entropy coding, and Segher Boessenkool told me in a private message that you are also doing a video codec. So I searched the archives and read a bunch of posts, but I never did find out any web address. And it's not on xiph.org either. So

This is a proposal for Ogg MIDI streams. It will also help other stream additions to Vorbis, as they should follow a similar model. Ralph has done much of the work on this, and also is working on MNG Ogg streams. Background ---------- I was contracted to do this work, so even if you can't think of a use for this, there is one ;) Basically with midi in Ogg, we can have a synchronized

Suddenly, quite a few people have jumped in and started active experementation and discussion about Tarkin, as well as playing with the very rudimentary test-of-concept 3d wavelet coder jack, hatamoto and I hacked on last year. For your use, I've added a new mailing list, tarkin-dev@xiph.org, for discussion and hacking on Tarkin. The list is run, linked and archived at xiph.org like the

I have been very busy for the last few months with school, during which time Jack and others have taken over ogg123. Now I have a week off for Christmas ("Winter Break" for the politically correct), so I have some free time. And what better place to spend it than at my computer? (heh) So anyway I decided to take a look at (what's left of) ogg123. Yuck. Eeew. Horror. The good news:

Does Winamp have Vorbis decode built-in? Winamp just put the finishing touches on their own vorbis plugin, and we expect it to ship in the next version. Sonique has already had Vorbis for some time (millions of

just for the record -- I think you mean video/theora when you mention vorbis+VP3. Vp3 is becoming Theora. Tarkin is another video codec project at Xiph. As for this whole MIME type issue, can someone enlighten me as to how this problem is addressed with Quicktime, Microsoft, and RealNetworks plug-ins today? Also, does an MPEG4 tag specify which audio codec is used? thanks - dan

Hi, I uploaded a new tarball to http://www.informatik.hu-berlin/~waechtle/w3d-0.1.21.tar.gz. The command line argument format has changed, it now expects a byterate/frame and a filename format string like "%i.ppm". Beside this I have added some minor changes in the coefficient transmission code. Please take a look on it, Jacks cat is only slightly blurred even at 1kB/frame -- the

For the past few years, users of the QuickTime container have faced a similar dilemma to what we have

I've been reading up on wavelet transforms the past week, and I plan to start on some video compression stuff next week, if it's any good (small chance :)) for Tarkin. So far I think I know what's happening, however there's one small thing I don't quite understand yet. If I understand correctly, you can do a 2d wavelet transform (I'm assuming a Haar transform here for

Smack my curiosity, but I encoded some songs in Vorbis mode 2 and tried to be able to distinguish the difference between that and the uncompressed WAVs. (*smacks self*) but here's what I noted: It's actually kind of hard to tell the difference :) (and I consider myself to have a decent set of ears, though not anywhere near the best) I got my accuracy to about 90%, but I couldn't

Thanks, Dan, for understanding what I meant with that sentence and clarifying it. I was indeed thinking of "video/theora" as MIME type to signify a theora & vorbis a/v-stream. If "Theora" is not the right name for this integrated stream, please come up with another one that is readable - I strongly dislike "oggvth". Silvia. -----Original Message----- From: Dan
