Windows Media Player HTML5 Extension for Chrome

The Windows Media Player HTML5 Extension for Chrome is an extension that enables Chrome users to play H.264-encoded videos (aka MP4) on HTML5 pages by using the built-in capabilities found in Windows 7.

Important Notes:
  • If you are running Windows 8, the extension will NOT work. We recommend that you download Internet Explorer instead. IE is a modern, standards compliant browser that remains compatible with older media technologies.
  • If you are running Windows 7, and your Chrome browser is version 33 or newer, the extension will NOT work. This is due to an architectural change in Chrome. The reason was articulated by the Chrome team in this article. As an alternative, we recommend that you download Internet Explorer instead.
  • If you are running Windows 7, and your Chrome browser is version 32 or older, you will still be able to install the plugin by following these instructions:

1. Download the extension from here by using the right click and select "Save Link As..." (DO NOT just open the link by clicking on it) and save it on your local machine.

2. In Chrome, select the menu Tools/Extensions.

3. Check the "Developer mode" box.

4. Drag & Drop the extension file (copied in step 1) on the extensions page in Chrome. Chrome will ask you to install the extension.

Release Notes for Developers

This Extension is based on a Chrome Extension that parses HTML5 pages and replaces Video tags with a call to the Windows Media Player plug-in so that the content can be played in the browser. The Extension replaces video tags only if the video formats specified in the tag are among those supported by Windows Media Player. Tags that contain other video formats are not touched.

The Extension also checks if the browser version already supports MP4 (H.264) video codec, if so the extension is not used.


The current version of the Extension still uses the Windows Media Player Plug-in APIs to control video playback, so there are some differences between the methods/properties defined in the emerging HTML5 standard and those available in the Windows Media Player plug-in. We are working to fix this limitation in the next release.
