How to embed an autoplaying YouTube video in an iframe?

html, iframe, javascript, youtube, youtube-api

Solution

This works in Chrome but not Firefox 3.6 (warning: RickRoll video):

<iframe width="420" height="345" src="http://www.youtube.com/embed/oHg5SJYRHA0?autoplay=1" frameborder="0" allowfullscreen></iframe>

The JavaScript API for iframe embeds exists, but is still posted as an experimental feature.

UPDATE: The iframe API is now fully supported and "Creating YT.Player objects - Example 2" shows how to set "autoplay" in JavaScript.

Problem

I am trying to embed the new iframe version of a YouTube video and get it to auto play. As far as I can tell, there is no way of doing this by amending flags to the URL. Is there a way to do it by using JavaScript & the API?
