Independent implementations?
Hullo, When people ask me what Vorbis's license terms are, I usually tell them that the bitstream format is in the public domain, that the reference libraries are licensed under a BSD-like license, and that the example programs are licensed under the GNU GPL. (Note the distinction between filespec and implementation here.) Meanwhile, Theora.org's FAQ doesn't say anything about the

Current state of theora & Windows port?
Hello everyone, I'm developing software for a marketing company which creates multimedia presentations. We're currently using proprietary Windows software, but are looking for a royalty-free cross-platform solution. It's important that the solution is royalty- and patent-free because the presentations are copied and given out in large quantities for free (as in beer ;-) We are

Some questions about Theora IP
Hello Theora developers, I'm doing some cursory research into Theora's IP status in preparation for asking Apple to reconsider the possibility of shipping an implementation. I have a few questions and I'm hoping knowledgeable people can help out. 1) What are the terms of any patent licenses or disclaimers, and do they have field of use restrictions or limitations on code for

Ogg MIME types scheme
Hello everybody, I hope to finish this MIME types discussion with these conclusions - it's taken enough bandwidth on these lists :).

Theora vs. Nullsoft NSV
How does the Theora project differ from Nullsofts NSV project?

Limiting bandwidth to around max. 8k per second - possible? UPDATE
Ok, we got it working with 176x144 resolution. The following string produced an image that was not falling behind too much for too long - basically a little when it was getting TONS of movement, and then catching up fast. "65 58 110 0 1 1 90 8 120 1 1 " Now, we need to get this working on a 320x240 resolution, too (as sadly VP3 does not support 160x120. Seems to be a little senseless,

A comparison of VP3, and two MPEG-4 variants
a couple points before I look at this too hard: "For VP3, since you can't do a constant quality encode" what? that should not be the case. Could be a QT-specific bug. Theora at any rate is certainly capable of doing constant-quality encode. This probably explains your standard deviation complaint -- VP3 is running a rate control alg, where the other codecs are just shooting for

VP3.2 video codec open sourced
this is slightly off topic and also it was posted to the tarkin list, but I think many people on this list are looking for an open source video codec. ;) On2 released the VP3.2 video codec as open source. I didn't read the license and could not say if it's really open source. http://www.vp3.com http://www.streamingmedia.com/article.asp?id=7871 --- >8 ---- List archives:

It's quiet. TOO quiet.
Whatever became of Ogg Theora? There seems to be still almost no news from Xiph or its developers regarding Ogg Theora. None at all since Mid-December, when the release of Alpha 2 was pushed back to a month ago... No news on plans for the second Alpha? No news of development "roadmaps"? No news on current developments or challenges that are stalling development? No CVS updates

Changing video quality during encoding
I don't know how to change a video quality on the fly - I want to provide a slider with a preview window, so user could see the result immediately in this window. I tried to send ICM_COMPRESS_FRAMES_INFO to encoder or calling ICSetState() - with no success however. Am I doing something wrong ? How can I set 'lDataRate', 'dwRate', 'dwScale' parameters ? I tried every

VP3 IDCT
Hi, Is there anything special I need to know about VP3's IDCT? I mean besides the fact that there are separate IDCTs to handle sparse coefficient matrices. Are the IDCT functions mathematically equivalent to any textbook IDCT functions?

troll or truth ?
Hello, I was discussing on the mplayer/mencoder ML about transcodingfrom Divx to Theora. I got these kind of answers: http://article.gmane.org/gmane.comp.video.mencoder.user/280 Of course I understoud only 50% of what he said, as well as I am not really used with codec and video glossary... But I generally understoud his opinion. What to think? I would like not to believe him, espacially when

Why is vp31 codec 2x - 3x slower than DivX codec ?
I have a simple test program which encodes, decodes and displays a single video stream ( at 2-3 fps ). It takes about 15% of CPU time when it uses DivX codec, but 35% when the VP31 codec is active. Is there any way to speed encoding/decoding with VP31 ? Or maybe VP31 is just much slower than DivX ? Kamil <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage:

Can't find the setup code
Well, I've been slamming my head against this all night, so it's time to ask for help... Having gotten together a reasonably decent port of what I thought was the whole API to the Ogg Way, complete with Ogg mem management and bitpacking, I started digging deeper in the code... only to find that it looks like I only have a middle stream handler. The encode and decode code both assume that
