...able on behalf of the public. So my question is, is it alright to create and distribute a Theora codec which isn't based on the Theora code from Xiph.org? If VP3 code is in Theora, and VP3 is patented, does that mean that you can't write/modify a non-Xiph Theora codec without infringing on On2's patents? Thanks in advance, Kyungjoon Lee

...non-assertion: <https://svn.xiph.org/trunk/theora/LICENSE >. This doesn't have a field-of-use restriction, but it does appear to limit the promise not to assert to the original VP3 code and modifications to that code. While looking for info, I found this thread from 2004 asking if On2's patents on Theora were licensed for independent implementations: <http://lists.xiph.org/pipermail/theora/2004-July/000544.html >. There didn't seem to be a clear conclusion at the time. Does anyone have further info on this? Are there additional agreements between On2 and Xip...

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. Cheers, Aris.

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: http://www.geocraw...

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....

Yes, the Theora codec is based on VP3, which is an earlier version of ON2's VP6 codec. Theora is currently at its alpha 3 release, and is stable enough to have been used already for streaming live video from a number of conferences, and for encoding several videos that can be found at www.theora.org. Development has progressed to the point that the value of the...

...des 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 archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'theora-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

...edge of the announcement said. And with that release, Mozilla ? maker of the Firefox browser ? and Google Chrome are expected to also announce support for HTML5 video playback using the new open codec. Google has controlled the VP8 codec ever since it finalized the acquisition of video codec maker On2 Technologies in February. When reached for comment as to its plans, a Google spokesperson told us the company had ?nothing to announce at this time.? The move comes as online video publishers are gravitating toward standards-based HTML5 video delivery, bolstered in part by the release of the iPad....

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

When you are ready to get peruse the VP3 plugin source code, look in xine-lib/src/libxinevdec/. There is a vp3/ subdirectory with the source code lifted from On2's source snapshot (circa December, 2001, I believe). There is also a vp3.c file in this directory which serves as the glue code between the VP3 lib and xine's plugin architecture. It also contains one more function lifted from On2's source: StartDecoder(). I have also posted my...

We try using the VP32 codec in a video conferencing application, replacing Intel indeo for obvious reasons. I must note that I have considered contacting ON2 for a license of the VP5 codec, but after sending emails for amore than a week and never getting back calls after they were announced, and after not reaching anyone early in the office there (and I have a substantial time difference), I have decided that we will not license anything for the time be...

In the fir_mem_up filter, the inner loop does a mac on the y0, y1, y2, y3 variables. What is the range of values of those variables? I would like to move the SHR 1 outside the loop after the mac has been done. Will this result in a 32 bit overflow of the y0, y2, y2 and y3 variables? -Fritz On2 Technologies, Inc. http://www.on2.com

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

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

Hi everybody, I'm currently writing a real time video conferencing tool for Windows and I want to use the Theora Library for this purpose. My questions are: 1.) is there a vfw implementation of theora 2.) if no, can I bundle the VP3 vfw codec that's available from On2's website with my application Best regards, Florian (Stuttgart, Germany)

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
