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

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:

[OT] Just saying hi!
I hope this list is small enough for not beeing banned when introducing oneself. So... Hi, I just subscribed to the theora-lists. I'm from the XVID project, so I know a deal about video and MPEG-4 in particular, but nothing about Vorbis/Theora etc., That's why I'm here, because I'm interested in patent-free alternatives. I guess there is no documentation of the current status

Quality of vp3.2 codec?
How good is the video compression in vp3.2? For example, how does it compare (bit rate & quality) to mpeg1, mpeg2, Divx, real Video 8+, Windows Media, etc. etc. It being open source is nice and all, but if it can't be reasonably competitive then there isn't much point to it. I just haven't seen anything that compares vp32 to anything else. (Although to be honest, I haven't

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

VP3/QT: A new kdxlqt_CodecVersion patch
The new 3.2.6.1 codecs work great with QuickTime 6 (thank you!), but there's no way for an application to identify them. And since the older 3.2.1.x and 3.2.2.x installers will actually *downgrade* the installed version of VP3, it would be nice if an application could warn the user. The attached patch increments kdxlqt_CodecVersion (and documents all the Component Manager arcana involved).

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,

Analogue artifact estimation
Hi List, Just batting a few ideas around here, but would it be possible to include in to the codec, estimation for common video artifacts that occur in the analogue world? For example, anything that's gone through a composite stage will likely have dot-crawl and false colour - if we can recognise this effect in the encoder, we can treat it as a special case. Other artifacts that come to

VP3/QT: Fix for QuickTime 6 GDI bug
QuickTime 6 for Windows breaks the VP3 codec quite severely--if you turn on "Safe Mode" (which forces QuickTime to draw through GDI), you'll see a white or black screen instead of video. This is logged as bug #2111990 in Apple's QuickTime feedback system. The fix is a classic one-liner, although it took me a long time to figure it out. :-/ Also attached is a patch to bump the

Cross-Compiling VP3 lib on Linux
Hi, I have been working with VP3 for some time now. Dan Miller from On2 just told me about this list. A few months ago, I managed to get On2's VP3 source snapshot to compile under Linux, a feat that many have apparently attempted and quickly abandoned. I compiled a small console app and the results of the experiment are explained here:

Boring but useful VP3/QT patches
I think I'll start with the simple stuff, just to be safe. :-) Here are some cvsignore updates, and a fix for the inter-project dependencies in the MSVC *.dsw file.

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

Web access to CVS tree - any chance this will be re-enabled at one point?
I tried it out on the Vp32 site - nothing in there. Says something of not matching the current tag. Nice. Theora's website does not have a web surface. Thomas Tomiczek THONA Consulting Ltd.

Where's TrueCast5?
Supposedly On2 transferred their Video Recorder and TrueCast5 streaming server into opensource along with VP3. Theora is obviously the VP3 project, and while I can find nothing on Xiph about it, the recorder source is offered on vp3.com; but I can find nothing on Xiph or vp3.com about what happened to Truecast5. I contacted On2 about whether TrueCast5 was really going to be open source, and they

On2 VP3 codec for Intel macs
Hi all, It's been a few years since I encoded a number of movies using the VP3 codec (v3.2) on my Quicksilver PPC. Now I have a new Intel mac and I'd like to play them. However, it seems that the codec offered on On2's website is only for the PPC architecture. Does anyone know a workaround or some other codec that works on the MacIntel platform? I'm using Quicktime Pro 7.

Theora and software patents
The list probably did not get this reply from D Richard Felker III. Having read quite a few patents I tend to agree with Richard: Software patents are very broad and even if I have not read the source code of Theora I would be surprised if it did not infringe several patents. However, I believe the argument that On2 has not been sued for infringing the MPEG-patents is a very strong argument.

theora spec
can anyone confirm that, unlike VP3, Theora in fact decodes images right-side-up? (VP3 managed to turn everything upside down on encode and reverse it on decode) The tests I'm doing indicate that Theora doesn't reverse the image -- the first coefficients encoded correspond to the upper-left corner of the frame. ___ Dan Miller (++,) Founder, On2 Technologies --- >8 ---- List
