Using A Hyperlink
If a web page includes a hyperlink to a media file, most browsers will use a "helper application" to play the file:

<a href="video.avi">
Click here to play a video file
</a>

The code fraction above displays a link to an AVI file. If the user clicks on the link, the browser will launch a helper application like Windows Media Player to play the AVI file.

only that is working, the others not.
