title: Why won't chrome play .mp4 or .webm?
body: <p>Chrome says "This plugin isn't supported" even though I have both video formats. Strangely I can play HTML5 video on other websites (with the same computer/browser). I looked at the source and they have mp4 first then webm. </p>
  
  <p>I tested the site with chrome from another computer and it works fine. Chrome is at the latest version on both computers.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>&lt;video preload="auto" autoplay loop&gt;
      &lt;source src="video/ssweb.mp4" type="video/mp4"/&gt;
      &lt;source src="video/ssweb.webm" type="video/webm"/&gt;
  &lt;/video&gt;
  </code></pre>
