Google removing H.264 video support from Chrome
Jan 12th
Google just announced on its Chromium blog that it will be removing support for the H.264 video codec from the Chrome web browser, in favor of supporting only its own open WebM codec (which, as we covered earlier, is based on On2 Technologies’ VP8) for HTML5 web videos using the <video> tag.
Earlier, Microsoft, Apple, and Google had decided to support H.264 (the dominant high-definition video codec) for HTML5 web video, while Mozilla and Opera supported only Google’s WebM codec. Now, Google’s move leaves Microsoft’s Internet Explorer 9 and Apple’s Safari 5 as the only major browsers supporting the H.264 codec without plugins. Ironically, since the vast majority of HTML5 video on the web today is encoded using H.264, Google’s move will likely reduce the usable installed base of HTML5 video-capable browsers.

Aug 25th
A new video from Pocketnow compares browsing speed on a Windows Phone 7 prototype from LG, the iPhone 4, and Google’s Nexus One on Android. Even though the software’s not finalized yet, Internet Explorer on Windows Phone 7 is surprisingly competitive with the WebKit-based browsers on the iPhone and Android, beating or matching them in most tests. No Flash, Silverlight, or HTML5 A/V support yet, but the browsing experience is at least on par with the competition and at least won’t be a hindrance to the platform’s success.
While the rendering engine is a mix of IE 7 and 8, Microsoft has clearly put a lot of effort into the user experience, with silky-smooth scrolling, multi-touch zoom, and tab management. It’s a completely different animal from IE Mobile 6 on Windows Mobile 6.x (though most WinMo owners use Opera Mobile or other browsers in any case).
Video after the break.

Microsoft Demos Internet Explorer 9: Fast, HTML5, No XP Support
Mar 17th
Microsoft gave a demo of its upcoming Internet Explorer 9 browser at the MIX conference earlier today. IE9 is mainly about two things– bringing the browser up to industry standards, like HTML version 5, and improving performance all around. Its new JavaScript engine, codenamed “Chakra,” is dramatically faster than IE8, currently scoring in between Firefox and Safari, and still a bit behind Chrome and Opera, on the WebKit SunSpider benchmark. The browser still scores only 55/100 on the Acid3 test for CSS compliance, but Microsoft’s promised that will improve by the time IE9 ships.

On the standards front, Microsoft has implemented a good deal of the HTML5 spec, including support for embedded video (using the H.264 codec) and audio (MP3 and AAC), scalable vector graphics (SVG2- for images that grow and shrink smoothly with different page sizes), and CSS3.
What does IE9 bring to the table that Chrome, Opera, and others don’t already have? The answer is that IE9 renders web pages using Direct2D, a new API introduced in Windows 7, and also supported in Vista and Server 2008, that provides hardware graphics acceleration for 2D rendering. This helps web pages look better (with sub-pixel text rendering) and load faster and is particularly beneficial for embedded videos.
Microsoft showed a demo of a page with two HD videos embedded using HTML5– IE9 played them both perfectly smoothly, while Chrome stuttered badly with just one video playing. The downside to this is that Direct2D doesn’t work on Windows XP, so neither will IE9. The company has made a test version available for download.
