• Demo of WebM Running on TI OMAP 4 Processor

  15 octobre 2010, par noreply@blogger.com (John Luther)
  Texas Instruments has made a video of HD-resolution (1080p) VP8 (WebM) video playing on their new TI OMAP™ 4 processor, in both Android and Ubuntu.
  
  
  
  (If you have a WebM-enabled browser and are enrolled in the YouTube HTML5 beta the video will play in WebM HTML5, otherwise it will play in Flash Player.)
  
  For more info about the OMAP 4 and the IVA 3 video accelerator that enables low-power HD playback of VP8 on the chip, see the TI web site.

  

• VP8 Documentation and Test Vector Contributions

  14 octobre 2010, par noreply@blogger.com (John Luther)
  Janne Salonen of the WebM team in Oulu, Finland (formerly On2 Finland) has added a tabular description of the VP8 syntax to the VP8 Bitstream Guide. The new annex provides a concise reference of the elements in the bitstream and we hope will make implementing and testing VP8 decoders easier. The updated document and source can be downloaded from our documentation page.
  
  We're working on more improvements to the bitstream guide and invite other community members to help. As with the VP8 code, we gladly give attribution credit to documentation contributors and have added an AUTHORS file to the bitstream-guide Git repository.
  
  New VP8 Test Vectors
  
  The Oulu team has also produced some new VP8 test vectors. We analyzed a large set of WebM videos and produced two important corner use cases. The first produces the worst-case memory bandwidth (i.e., lots of global motion, all fractional motion vectors). The second produces the worst-case boolean decoder bin rate over dozens of consecutive frames. These vectors have been added to the VP8 test repository. Our team will consider other corner cases in the next batch of streams we add to the repository.

• A Digital Media Primer for Geeks

  24 septembre 2010, par noreply@blogger.com (John Luther)
  Our friend Monty Montgomery (creator of the Vorbis audio codec used in WebM) has started a video series about digital media. The first episode is an excellent overview of "the technical foundations of modern digital media."
  
  You can stream WebM versions of the video in your favorite WebM-enabled browser or download it to your desktop and watch it one of many WebM-enabled media players. Supported browsers and players are listed on our site.
  
  There's also a companion Wiki.

  Encoding.com, one of the world's largest video transcoding services, has released WebM encoding support and also included six easy-to-use output presets. You can read more at the encoding.com blog.

  

• WebM Decoding Improvements in Google Chrome 6

  10 septembre 2010, par noreply@blogger.com (John Luther)
  Google Chrome 6 for Windows, Mac and Linux was released last week. We want to congratulate the Chrome team and thank them for their contributions to the WebM project.
  
  Making the web faster is a core goal of Chrome, and we are happy to report that across a set of test clips Chrome 6 decodes VP8 video significantly faster than the developer version that was released at our launch in May. On single-core Intel machines the average improvement is about 20%; on multicore processors it ranges from 15% (two cores) to 50% (four cores). If you want to try it for yourself, get Chrome 6 and then follow our instructions for playing WebM videos on Youtube.
  
  We’ve made further decoding speed gains in Chrome 7 dev channel, and are working on better video rendering to further improve the WebM user experience.
