FLV that autoplays and has no controls

Browsers that already have Flash installed can play SWF files automatically. If your video is already encoded as a looping SWF object, you can embed it directly on the page and it will play automatically and loop without controls.

If, however, you have an FLV file instead you’ll need a video player to play it in. Flash does not play FLV files alone in a web browser! Try any one of these flash video plug-ins on your site. You might not be able to get the automatic loop, though.

Here’s a good online media converter that handles several formats: http://media-convert.com/

Here are instructions for embedding an SWF file in a web page: http://www.w3schools.com/flash/flash_inhtml.asp
