Hi all, Sorry for the VP8 question on the Theora list, but I think all the relevant people are here :) I'm using Icecast to distribute some Ogg Theora streams at the moment with a view to adding VP8 along side these in future. Ideally I'd just use Ogg VP8+Vorbis, I know there is a mapping for this already but ho...

"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...

Hi All Is it a possible case that an ogg file contains VP8 frames. I know ogg file generally contains vorbis, theora frames. Recently I came across an ogg file that contains OPUS frames. Is there any tool, that can take a webm file as input, and output an ogg file with preferably only video (no audio) frames. Please let me know. Thanks Austin --------...

I'd be very interested in seeing an article or report by one of the Theora devs regarding VP8, as opposed to the article by the X264 dev, seeing how the code-base between VP8 and Theora share a common lineage. I would think the familiarity would allow perhaps a better analyses, if not completely unbiased. Your thoughts? mikesum32 -------------- next part -------------- An HTML attachmen...

...fbridge works with some minor quirks (lost connections sometimes, I guess plain old nat issues). Just relaying audio+video with confbridge to a handful of participants seems to use quite a bit of cpu thought. Screen-share: This works, but Confbridge is not very happy about a channel with video (vp8) and not audio and is printing this 80 times a second: WARNING[8919][C-00000000] channel.c: Unable to find a codec translation path from (vp8) to (slin) WARNING[8919][C-00000000] chan_sip.c: Asked to transmit frame type slin, while native formats is (vp8) read/write = unknown/unknown WARNING[891...

Hi All, Anybody have idea that how to add VP8 codec into Asterisk 1.8 and from where to download.

Hello , We are using Icecast for few years in a small french radio station with great success ! ( hitting 60 simultaneous listeners sometimes :-) ) http://www.radiogalere.org:8080/ Now we plan to stream the webcam capture of the studio, we 've done a test with Ogv/theora @128kb video with great sucess although none of the HTML5 browser wher able to keep on playing the stream after few

Google has opened up VP8, and has lined up about 40 companies/organizations (including xiph) in a coordinated launch: http://www.webmproject.org/ Anyone know where there are quality comparisons between H.264, Theora, and VP8? -SteveK

Hey everyone, I am new to the dev list here, but my question specific about any development towards webrtc integration. Let me explain, a couple colleagues and I are currently working on our webrtc build at live.mayfirst.org site useing nodejs. We are currently looking into seeing if there is any development of a javascript source client? This would be used to send the webrtc room to a public
