Google releases WebM video plug-in for IE9
Google has developed a WebM plug-in for Microsoft's Internet Explorer 9. The preview plug-in is now available to download for IE9 on Windows 7 and Windows Vista, though the release seems rushed to happen on the day of the IE9 launch. For example, the "known issues" page is, at time of writing, "not yet available". The developers did, however, comment on the download page; "They said elephants couldn't ride flying dolphins. They said that one of the world's most popular browsers couldn't play WebM video in HTML5. They were wrong."
The release of the plug-in comes after Microsoft released HTML5 H.264 plug-ins for Google's Chrome in February and Mozilla's Firefox back in December of last year. The aim of the plug-ins is to enable the HTML5 <video> tag to play more formats that the browser's authors intended; Mozilla and Google browsers only play only WebM based video, while Microsoft supports any installed codec but does not come with a WebM/VP8 codec, preferring H.264 by default.
