The HTML5 Extension for Windows Media Player Plugin-in for Firefox is an add-on that enables Firefox users to play H.264-encoded videos on HTML5 pages by using the built-in capabilities found in Windows 7.

The plug-in looks for HTML5 video tags and passes the video to the Windows Media Player plug-in for playback.

This Extension adds to the functionality of the extremely popular earlier Windows Media Player Plug-in for Firefox to enable web pages that use the emerging HTML5 standard.

Dplayer is an open source, easily extend-able, HTML5 video player that allows users to easily embed videos in any page, blog or site using the newest web standards.
