OSI President Questions WebM Patent License Compatibility with Open Source
Via the H comes a report that the Simon Phipps, current President of the Open Source Initiative, thinks that the VP8 patent Cross-license agreeement Google brokered with the MPEG-LA is incompatible with the Open Source definition. The primary problems are that the license is not sub-licensable and only covers certain uses, leading to conflict with OSD clauses five, six, and seven. Phipps concludes: "As a consequence, I suggest the license is flawed when considered in relation to open source projects and is likely to be negatively received by many communities that value software freedom. Doubtless a case can be made that the patent license is optional, but I suspect the community issues may remain. Once again we're left with our fingers crossed. Google's making the right noises, but this draft agreement seems like a particularly unworkable approach for free and open source software. Its failure to allow sublicensing seems like a major flaw. Even if this doesn't result in a requirement for all end-users to sign the agreement, the discrepancies between this document and the OSD leave it disruptive to open source adoption of VP8." -
Google and MPEG LA Reach VP8 Patent Agreement
First time accepted submitter Curupira writes "The official WebM blog announced that MPEG LA has licensed all VP8 essential patents to Google Inc., allowing the company to sublicense the described techniques it to any VP8 user on a royalty-free basis." TechCrunch offers a bit more analysis. -
Google Announces WebM Community Cross Licensing
theweatherelectric writes "Google's WebM project has announced the formation of the WebM Community Cross-License Initiative. Members of the WebM-CCL agree to license patents they may hold that are essential to WebM technologies to other members under royalty-free terms. This initiative would seem to address some of Microsoft's concerns about WebM. Meanwhile, the MPEG LA appears to have remained silent after the submission period of its call for patents essential to WebM ended over a month ago." -
VP8 Decoder Implemented In Flash Using Alchemy
An anonymous reader writes "Mozilla's Chris Double has an interesting post on his blog about a port of the VP8 decoder to Flash. He writes, 'Ralph Hauwert has been posting on twitter about work he's done on getting WebM decoding to work by compiling the libvpx source code using Adobe's Alchemy technology. Alchemy is a research project that allows compilation of C and C++ libraries into code that runs on the ActionScript virtual machine used by Flash.' Of course, it's very slow and Adobe says that they'll bring native VP8 support to Flash in due course, but implementing a VP8 decoder in ActionScript is an interesting project nonetheless." -
New VP8 Codec SDK Release Improves Performance
An anonymous reader writes "Google released a new version of the VP8 codec SDK on Thursday. They note a number of performance improvements over the launch release including 20-40% (average 28%) improvement in libvpx decoder speed, an over 7% overall PSNR improvement (6.3% SSIM) in VP8 'best' quality encoding mode, and up to 60% improvement on very noisy, still or slow moving source video. In other WebM news, Texas Instruments has a demo of 1080p WebM video playing on their new TI OMAP 4 processor, in both Android and Ubuntu." -

Google Releases New Image Format Called WebP
An anonymous reader writes "Google has released WebP, a lossy image format based on the image encoding used by VP8 (the video codec used in Google's WebM video format) to compress keyframes. According to the FAQ, WebP achieves an average 39% more compression than JPEG and JPEG 2000 while maintaining image quality. A gallery on the WebP homepage has a selection of images which compare the original JPEG image with the WebP encoded image shown as a PNG. There's no information available yet on which browsers will support the WebP image format, but I imagine it will be all the browsers which currently have native WebM support — Firefox, Chrome, and Opera." Independent analysis of WebP is available from a few different sources. -
IE9 Preview Touts Cross Browser Compatibility
An anonymous reader writes "Microsoft's Internet Explorer 9 development team has announced the availability of the third IE9 platform preview release on the IE blog. Dean Hachamovitch writes, 'The third Platform Preview of Internet Explorer 9, available now, continues the deep work around hardware acceleration to enable the same standards-based markup to run faster. This is the latest installment of the rhythm we started in March, delivering platform preview releases approximately every eight weeks and listening to developers. You'll see more performance, same markup, and hardware-accelerated HTML5.' The announcement focuses on cross-browser compatibility, noting that when 'developers spend less time rewriting their sites to work across browsers they have more time to create amazing experiences on the Web.' Curiously, however, the video embedded in the page works only in some browsers. Dear Microsoft, IE9 supports many royalty-free, web-compatible formats out of the box (HTML, CSS, WOFF, PNG, and the like) so why not at least one more?" -
Theora Development Continues Apace, VP8 Now Open Source
SergeyKurdakov writes "Monty 'xiphmont' Montgomery of the Xiph Foundation says the latest action-packed, graph- and demo-clip-stuffed Theora project update page (demo 9) is now up for all and sundry! Catch up on what's gone into the new Theora encoder Ptalarbvorm over the last few months. It also instructs how to pronounce 'Ptalarbvorm.' Ptalarbvorm is not a finished release encoder yet, though I've personally been using it in production for a few months. Pace on improvements hasn't slowed down — the subjective psychovisual work being done by Tim Terriberry and Greg Maxwell has at least doubled-again on the improvements made by Thusnelda, and they're not anywhere near done yet. As a bonus Monty gathered all Xiph demo pages in one place." Also on the video codec front, and also with a Xiph connection, atamido writes "Google has released On2's VP8 video codec to the world, royalty-free. It is packaging it with Vorbis audio, in a subset of the Matroska container, and calling it WebM. It's not branded as an exclusively Google project — Mozilla and Opera are also contributors. Builds of your favorite browsers with full support are available." An anonymous reader points out this technical analysis of VP8. -
