Hi, Since a number of people are eager to try out the native VP3 decoder in xine, I have made a patch available, bz2-compressed: http://www.pcisys.net/~melanson/codecs/xine-vp3-decoder-patch.bz2 To work with this patch: 1) Get the latest xine-lib from CVS. Visit this page for more details: http://sourceforge.net/cvs/?group_id=9655 The module name is xine-lib, but you will also need

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

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

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

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.

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:

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).

Hi, So it took a little while to get here but VP3 through ffmpeg is finally starting to achieve viewable results. It partially works right now. Keyframes only. And monochrome. Oh, and the picture is upside down (something I did not realize about VP3 until I let it fly just now). Anyway, here is a picture of ffmpeg's VP3 decoder in action using xine:

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

Dan, In reviewing the code, derf came across the DCSearchPoints array in QuadCodeDisplayFragments(), encode.c:696. It looks like it specifies a search order for nearby coded fragments for prediction if there isn't a nearest neighbor. However, the upper search bound is defined as *0*, so the search loop (line 917) is never executed and it always falls back to the last coded fragment.

First, an introduction: I work in a group that makes educational software. In the coming months, we're planning to release our entire Mac/Windows runtime under the GPL. We currently encode our audio with MP3 and our video with VP3. For playback, we rely on QuickTime 5 on MacOS and Windows. In the short run, we'd like to help maintain the VP3 QuickTime codecs, preferably without

hi folks I've posted a new version of the Theora spec, same place as before: ftp.vp3.com/theora/spec name: vp3 pass: vp3dev This one actually works (the old one had a significant bug). Many editorial changes too. Please review & comment. - dan ps Rillian, I would have updated CVS myself but my pub key stuff is not working. --- >8 ---- List archives: http://www.xiph.org/archives/

It looks like there's more QT 6 trouble, and this is specific to the post-3.2.5.x builds. I'm on it, and will try to sort things out by Monday.

Hi, A few questions: Is libtheora strictly backward compatible with VP3? Can I set it up to shove raw VP3 data through and trust it to decode the same way as On2's open source code did, loop filters and all? Also, is libtheora just supposed to be a C-based reference implementation? I was looking through the code and noticed a distinct lack of any kind of optimizations. Naive tree-based

I found out about vp3 from the new winamp and coincidentally i also happen to be trying to find a suitable solution to broadband streaming. I have used flaskmpeg to create a 17mb .avi file from an 82mb Mpeg 1 file and it looks great it took about twenty minutes to encode. It runs for eight minutes and the audio is also fantastic using the lame encoder. However when I try to do the same in

I tried out Theora to see what the future holds, and see some pros and cons. As a great plus, I have noticed that, even at the lowest quality (ie. "-v 0"), the detail, and overally quality is clearly better than anything else available. On the negative side, at qualities comparable to MPEG4, I've notcied a great deal of blockiness. It's not as bad as blockiness from other

Hello, Due to some licensing changes (and because I actually want to promote this, too) I want to replace our usage of Intel Indeo 5 with VP3 in a video conferencing pplication we are just developing (check: http://www.stnadby24.no/ for infos (english language) on the application). My problem is this: I need to define at least the bandwidth. I am feeding full frames from the camera with a given
