Remember when Microsoft released an HTML5 H264 plug-in to incorporate native H264 support for Windows 7 users running HTML5 on Firefox a couple of months ago? Well the software giant has now turned its attention onto Chrome and has released an identical extension for Google's browser too.
The plugin gets access to the H.264 support that is already been built into Windows 7. Technically, whenever you access a video from an HTML5 webpage, the video tags are replaced by a call to the Windows Media Player plugin. This plugin then allows you to play content directly on the page.
You can get the extension from here. It requires Chrome 8.0 or later and Windows 7, so make sure you have both those requirements met.
