An anonymous reader writes "As if the current situation with software patents wasn't bad enough, it appears a new phenomenon is emerging: companies are watching the commit logs of open source projects for ideas to patent. In this case, Tandberg filed a patent that was step-by-step identical to an algorithm developed by the x264 project — a mere two months after the original commit. The particular algorithm is a useful performance optimization in a wide variety of video encoders, including Theora."

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.

An anonymous reader writes "Three FFmpeg developers — Ronald Bultje, David Conrad, and x264 developer Jason Garrett-Glaser — have written the first independent, free implementation of a VP8 video decoder. Benchmarks show that it's as much as 65% faster than Google's official libvpx. The announcement also gives a taste of what went into the development process, as well as the optimization techniques used. Currently it's only fully optimized on x86, but ARM and PowerPC optimizations are next in line for development."

An anonymous reader writes "Well, that didn't take long. Larry Horn, CEO of MPEG-LA, the consortium that controls the AVC/H.264 video standard, says the group is looking at creating a patent pool license for VP8 and WebM, Google's new open source, royalty-free HTML5 video format... So much for a Web video standard unencumbered by patent issues." We talked about VP8/WebM a couple of days ago when Google open sourced it. Reader Stoobalou points out another late-night email from Steve Jobs, who was asked to comment on VP8 vs. H.264. Jobs laconically sent a pointer to the technical analysis we linked before, where the poster says "VP8 copies way too much from H.264 for anyone sane to be comfortable with it, no matter whose word is behind the claim of being patent-free."

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.

An anonymous reader writes "The x264 project has announced the first free software encoder to be able to generate Blu-ray compliant video. In addition, the announcement comes with a torrent of an x264-encoded Blu-ray disc containing entirely free content, such as the Open Movie Project videos. While there are still no free software Blu-ray authoring tools, hopefully this will change now that video and audio are taken care of so that everyone will be able to make their own Blu-rays without expensive proprietary software. Additionally, it seems the Criterion Collection is a friend of free software, having sponsored the effort to confirm x264's compliance with the Blu-ray spec."
