[Resending since I sent my first mail before subscribing and I think it didn't went through. I apologize if you got this twice.] Hello everyone, I would like to participate as a student in google Summer of Code and I was very excited to discover that Xiph is one of the mentoring organizations, because I am a big fan of both Vorbis and Theora. So I would love to contribute to a Xiph.org

FYI, Anne van Kesteren (he's an Opera developer) has written an update about the state of the HTML5 <video> element in browsers and big websites: http://annevankesteren.nl/2009/05/web-video Two bits from the post: 1) the YouTube demo uses the H.264 codec, but I guess this will change if they want compatibility with Firefox 3.5; 2) Chrome uses FFmpeg for the decoding; can this

Hi: I'm running rsync-3.0.7 from a freebsd-7.2 x32 box and a freebsd-8.0-x64 box. All files seem to replicate fine except the setup programs for K-Lite Codec Pack e.g. http://fileforum.betanews.com/sendfile/1094057842/2/1265418487.c39d017a17a32d0bf3691cb9f6f8121de588d44f/K-Lite_Codec_Pack_570_Standard.exe [10667732 bytes] -or-

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.

this just in -- who can take it? (Mau??)

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

Hello, it's a great pleasure for me to announce the availability of libtheora alpha8 and the imminent availability of beta1. http://downloads.xiph.org/releases/theora/libtheora-1.0alpha8.tar.gz alpha8 brings a completely new decoder (feature complete, lifted from derf's theora-exp) and additional control over the encoder (applications now can specify their own set of quantization

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

"Google will soon make its VP8 video codec open source, we?ve learned from multiple sources. The company is scheduled to officially announce the release at its Google I/O developers conference next month, a source with knowledge 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

I noticed that in the narrow band and wide band destroy functions only the main pointer is being freed. I think that it should be: void nb_decoder_destroy(void *state) { DecState *st; st=(DecState*)state; speex_free (st->inBuf); speex_free (st->excBuf); speex_free (st->innov); speex_free (st->interp_qlpc); speex_free (st->qlsp); speex_free

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

Hello list, When I convert an yuv pixel into rgb using the recipies in http://www.fourcc.org/fccyvrgb.php I get an accurate color conversion but the contrast seems to be decreased. If i write, e.g., the pixel directly into an sdl yuv_overlay, I get a well-contrasted frame, however, if I convert the pixel to rgb and call SDL_MapRGB, I get a contrast-decreased frame. Thanks, Ribamar

The site: http://www.techimo.com/articles/index.pl?photo=33&SID=12&tag=SNnb323 has a review & comparison of several mpeg-4 codecs, and they also include vp3. (Be warned, it's a very big web page, due to all of the image examples!) Not really all that informative, but I thought somebody might be interested in hearing about it. *** On2 VP3 3.2.5.0 Positive: extreme low bitrate

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

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:

Our discussion in the "Theora Camcorder" thread has been great, but I didn't see a direction evolve for action yet. So, I'd like to propose the creation of a community website that will be focused specifically on this kind of thing, partnered with the Xiph Foundation. I'm also more than happy to host said website, as I have more than ample server capacity for that. I just

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,

Hi, I just wanted to say that I've recently become a fan off the ogg movie format. I haven't really done much with video before, but I recently got a Canon DSLR which can record HD movies at 30 fps, 720p. The resulting files are great, but too large to share over the web. After trying a few different encoding tools, I quickly found that ffmpeg2theora is super easy to use, gives good

I'm pleased to announce the second alpha release of our next generation encoder for the free Theora video format, codename "thusnelda". The second release incorporates a number of changes which improve both compression efficiency and execution speed. This release includes working MSVC project files, but the assembly optimization hasn't yet been ported, so performance there will
