Google's James Zern writes, 'Transcoding all new video uploads into WebM is an important first step, and we’re also working to transcode our entire video catalog to WebM. Given the massive size of our catalog — nearly 6 years of video is uploaded to YouTube every day — this is quite the undertaking. So far we’ve already transcoded videos that make up 99% of views on the site or nearly 30% of all videos into WebM. We’re focusing first on the most viewed videos on the site, and we’ve made great progress here through our cloud-based video processing infrastructure that maximizes the efficiency of processing and transcoding without stopping. It works like this: at busy upload times, our processing power is dedicated to new uploads, and at less busy times, our cloud will automatically switch some of our processing to encode older videos into WebM. As we continue to transcode the remaining inventory, we’ll keep you posted on our progress.'

They write, 'Nokia has confirmed that it has closed the source code for the Symbian smartphone operating system. It says that despite it describing its new model for Symbian smartphone operating system development as "open and direct" the "open" part did not refer to "open source" but to being "open for business". The "open and direct" model is designed, according to Nokia, to "enable us to continue working with the remaining Japanese OEMs and the relatively small community of platform development collaborators we are already working with".'

She writes, 'On Wednesday, I gave a talk at Google about WebVTT, the Web Video Text Track file format that is under development at the WHATWG for solving time-aligned text challenges for video. I started by explaining all the features that WebVTT supports for captions and subtitles, mentioned how WebVTT would be used for text audio descriptions and navigation/chapters, and explained how it is included into HTML5 markup, such that the browser provides some default rendering for these purposes. I also mentioned the metadata approach that allows any timed content to be included into cues.' Slides of her talk are also available.

They write, 'Power consumption is an important consideration in building a modern browser and one objective of Internet Explorer 9 is to responsibly lead the industry in power requirements. The more efficiently a browser uses power the longer the battery will last in a mobile device, the lower the electricity costs, and the smaller the environment impact. While power might seem like a minor concern, with nearly two billion people now using the Internet the worldwide implications of browser power consumption are significant.'

CNET's Stephen Shankland writes, 'In an effort to bring its Web video technology to a browser that doesn't support it, Google has released an IE9 plug-in to play WebM video. The move won't bring an end to the industry scuffle over the best way to build video into the Web, but it will mean that allies behind Google's preferred mechanism will be able to reach beyond the three browsers that support WebM today, Google's Chrome, Opera Software's Opera, and Mozilla's Firefox. Apple's Safari and Microsoft's brand-new IE9 support the rival H.264 video codec (though IE9 requires Windows 7 or an updated version of Windows Vista).' Further detail can be found on the WebM components for IE9 page on the WebM website.
theweatherelectric writes: The WebM Project has made available (but only by request) the RTL source code of their VP8 hardware encoder. They write, 'The H1 encoder offloads the entire VP8 video encoding process from the host CPU to a separate accelerator block on the SOC. It significantly reduces power consumption and enables encoding of 1080p resolution video at full 30 FPS, or 720p at 60 FPS. Without a hardware accelerator like the H1, modern multi-core mobile devices can only encode video at around VGA 25 FPS, and are not able to do much else while doing that.' This follows on from the recent 0.9.6 release of the VP8 SDK which improved encoder speed and image quality.
theweatherelectric writes: Mozilla's Robert O'Callahan has posted an article on his blog in which he investigates the performance differences between Firefox 4 and IE9. He writes, 'As I explained in my last post, Microsoft's PR about "full hardware acceleration" is a myth. But it's true that some graphics benchmarks consistently report better scores for IE9 than for Firefox, so over the last few days I've been looking into that. Below I'll explain the details [of] what I've found about various commonly-cited benchmarks, but the summary is that the performance differences are explained by relatively small bugs in Firefox, bugs in IE9, and bugs in the benchmarks, not due to any major architectural issues in Firefox (as Microsoft would have you believe).'
