You’ve probably read the news already, so I’ll cut right to the chase: earlier today, Internet Explorer’s big kahuna Dean Hachamovitch made an announcement about Internet Explorer 9 support for HTML5 video in Blogging Windows:
In its HTML5 support, IE9 will support playback of H.264 video as well as VP8 video when the user has installed a VP8 codec on Windows.
(And in case you were wondering, the WebM format — also announced earlier today — uses the VP8 codec.)
If you want to take an early version of IE9 for a spin, visit the Internet Explorer 9 Test Drive site and download the latest preview (as of this writing, it’s Platform Preview 2).
