title: no autoplay in iframe HTML5 player on mobile (Android Chrome and Firefox)?
body: <p>I've recently run into an issue when embedding a video with standard iframe embed code and adding autoplay=1 like this:</p>
  
  <pre><code>&lt;iframe width="420" height="315" src="http://www.youtube.com/embed/Le4kjAIcj4k?rel=0&amp;amp;autoplay=1" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>The results when testing:</p>
  
  <ul>
  <li>autoplay works both on desktop and mobile if the Flash-version of the
  player is loaded (if Flash is present &amp; no HTML5-beta participation cookie is present)</li>
  <li>it works in the HTML5-version on the Desktop as well</li>
  <li>but <strong>does not autoplay in the HTML5 mobile version</strong> (tested on Android
  4.1.2 with both Firefox Mobile and Chrome <a href="https://dl.dropbox.com/u/9207036/autoplay.html">on this page</a>, on Android you need to make sure you don't have flash).</li>
  </ul>
  
  <p>Is this a known issue? Any workaround?</p>
