Microsoft today announced that IE9 now play HTML5 video in both the industry-standard H.264 format and the WebM format. "With the WebM Project's release of WebM Components for IE9 (Preview), Windows customers running IE9 can play WebM videos in Web pages. IE9 is the only browser today committed to supporting both formats directly," said Dean Hachamovitch.
"In the newly published Video Format Support demo at the IE Test Drive site, you can try out for yourself Web pages with both video formats on them in different browsers. You can see how Web site authors can adjust the experience on their pages based on the browser and operating system the visitor is using.
You can also see the opportunity that HTML5 video offers publishers to make video an integral part of the Web experience, especially when it is fully hardware accelerated."
"IE9 supports HTML5 video using H.264, a high-quality and widely-used video format that serves the Web very well today. Microsoft has released add-ons for both Firefox and Chrome on Windows to add support for HTML5 video in H.264. "(These add-ins support the most basic consumer video playback scenarios in other browsers; to support additional HTML5 video scenarios, other browsers would need better video codec extensibility support or direct support for OS-provided video codecs.)."
IE9 supports HTML5 video using WebM for Windows customers who install third-party WebM support."
