What is the advantage of using JavaScript to determine a viable embedding method over using alternative streams and fallback content that can include the OBJECT element where appropriate? Chris

Querying the browser's <video> capabilities allows JS to decide what sort of embedding method to use. It's an essential migration feature. -- Tim Starling
