title: html5 video not working on tablet
body: <p>I have a website with a big video in the background and I used HTML5 video for it. It does all I want on desktops, I can't make it work on tablets though (don't need it on mobiles) - instead of a video I see a black background only. </p>
  
  <p>Code below:</p>
  
  <pre><code>&lt;div id="video-container"&gt;
  &lt;video autoplay loop class="fillWidth"&gt;
  &lt;source src="http://link/vid.mp4" type="video/mp4"/&gt;
  &lt;source src="http://link/vid.ogv" type="video/ogg"/&gt;
  &lt;source src="http://link/vid.webm" type="video/webm"/&gt;
  Your browser does not support the video tag. I suggest you upgrade your browser.
  &lt;/video&gt;
  </code></pre>
  
  <p>Is it caused by the autoplay option? If so, is there any workaround?
  Thanks,
  S.</p>
