Getting an Embedded YouTube Video to Auto Play and Loop

I am trying to get a basic Youtube video to auto play and auto loop embedded on a page, but I'm having no luck.

<div style="text-align: center; margin: auto"><object type="application/x-shockwave-flash" style="width:1120px; height:630px;" data="http://www.youtube.com/v/GRonxog5mbw?rel=0&amp;loop=1&amp;autoplay=1&amp;showsearch=0&amp;version=3&amp;showinfo=0&amp;modestbranding=1&amp;fs=1">
<param name="movie" value="http://www.youtube.com/v/GRonxog5mbw?rel=0&amp;loop=1&amp;autoplay=1&amp;showsearch=0&amp;version=3&amp;showinfo=0&amp;modestbranding=1&amp;fs=1" />
<param name="allowFullScreen" value="true" />
<param name="allowscriptaccess" value="always" />
</object></div>
