title: Vimeo embeded video fails to play on Android?
body: <p>When I embed <a href="https://vimeo.com/43426940" rel="nofollow">100 Riffs (A Brief History of Rock N' Roll)</a> in a <a href="http://twitter.github.io/bootstrap/scaffolding.html#fluidGridSystem" rel="nofollow">Twitter Bootstrap container</a> with <a href="https://github.com/davatron5000/FitVids.js" rel="nofollow">FitVids.js</a> for responsive resizing:</p>
  
  <pre><code>&lt;div class="span12" id="video"&gt;
      &lt;iframe src="https://player.vimeo.com/video/43426940?title=0&amp;amp;byline=0&amp;amp;portrait=0" width="500" height="281" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen&gt;&lt;/iframe&gt;
      &lt;p class="text-center"&gt;Isn't the placeholder video awesome?&lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>It functions fine on a desktop, but acts oddly on Android (CM 10.1 Nightly, Android 4.2.2) browsers:</p>
  
  <ul>
  <li><em>Google Chrome</em> - Audio playback starts, but video playback does not</li>
  <li><em>Mozilla Firefox</em> - Audio and video playback do not start</li>
  </ul>
  
  <p>Yet, the player works fine on Vimeo's own mobile site. What am I doing wrong?</p>
