title: How to change "application/octet-stream" to "video/mp4" in HTML5
body: <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt; 
     &lt;head&gt; 
       &lt;meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"&gt;     
     &lt;/head&gt; 
     &lt;body&gt; 
       &lt;video id="video" controls src="${maps.url }" height="598" width="782"&gt; 
          Your user agent     does not support the HTML5 Video element. 
       &lt;/video&gt; 
     &lt;/body&gt; 
  &lt;/html&gt;
  </code></pre>
  
  <p>This is my code for HTML5 Video. When I run this code in IE 10, the data type is displayed as "application/octet-stream", so it shows an error message. So I know I should switch the type to  "video/mp4".</p>
  
  <p>Does anybody know what I should add to the code to change the type?</p>
