title: HTML5 Video not auto-playing
body: <p>I'm requesting this chunk of html from a mysql database:</p>
  
  <pre><code>&lt;p&gt;Hello.&lt;br&gt;&lt;video src="video/hi.mp4" width=100% height=100% autoplay="autoplay"&gt;&lt;/video&gt;
  </code></pre>
  
  <p>It displays, but won't autoplay. On a static HTML page it goes off without a hitch.
  The request comes from an ajax call for a matching keyword that is being typed into a input bar.</p>
  
  <p>Any ideas?</p>
