Hi @woohoo,
Thanks for the post.
For some oEmbed providers such as YouTube, you can create an <iFrame> and append player parameters directly to the end of the URL.
The code would look like so:
<iframe id="ytplayer" type="text/html" width="640" height="390"
src="http://www.youtube.com/embed/M7lc1UVf-VE?autoplay=1&origin=http://example.com"
frameborder="0"/>
