title: HTML5 <video> tag not working in Internet Explorer
body: <p>The following code displays a video control. The user can successfully watch the video in Safari, Firefox, Chrome, both via desktop and mobile browsers. </p>
  
  <p>The video control does NOT work in the latest version of Internet Explorer (11?) -- neither desktop nor mobile. </p>
  
  <p>Here's the code in question:</p>
  
  <pre><code> &lt;div id="videoDiv" class="wrappableBlock"&gt;
       &lt;h2&gt;&lt;img src="/code/images/video.png"/&gt;Introductory Video&lt;/h2&gt;
       &lt;video controls preload="metadata" &gt;
         &lt;source src="/code/images/video.mp4#t=8" type="video/mp4" &gt;
         &lt;source src="/code/images/video.ogg#t=8" type="video/ogg" &gt;
         &lt;em&gt;Sorry, your browser doesn't support HTML5 video.&lt;/em&gt;
       &lt;/video&gt;
   &lt;/div&gt;
  </code></pre>
  
  <p>According to the documentation referenced <a href="https://developer.mozilla.org/en-US/docs/HTML/Supported_media_formats" rel="nofollow">here</a>, Internet Explorer should be able to process MP4 video files provided that they are H.264 / AAC encoded. My video meets these specifications.</p>
  
  <p>The symptoms are:</p>
  
  <p>(1) In desktop version of Internet Explorer (11.0) the video player shows up but pressing the play button does nothing.</p>
  
  <p>(2) In the mobile version (latest version as of 5/12/14 @ Microsoft store) the video player shows as an inoperable black square. The dimensions of the square are correct but there's no way to interact with it.</p>
  
  <p>In no case does my default code <code>&lt;em&gt;Sorry, your browser doesn't support HTML5 video.&lt;/em&gt;</code> display.</p>
  
  <p>What else shall I try? It's not necessary to find a working solution for IE versions prior to 10. </p>
  
  <p><strong>UPDATE</strong>: Another tidbit.. Entering the full path to the video file(s) in the IE URL area executes a download of the file. So it's not a "file not found" situation. It's accessible.</p>
  
  <p>Also... The Internet Explorer network tab shows that IE isn't even bothering to query for the file. As opposed to the other browsers which automatically execute a GET request for the video.</p>
