title: Safari does not play HTML 5 video (IE 9, Firefox and Chrome all do)
body: <p>I am aware that I need ogg for Chrome and Firefox and H.264 for IE 9 and I use multiple sources to support all browsers with my video, and I also have the required meta to keep IE 9 happy enough:</p>
  
  <pre><code>  &lt;!DOCTYPE html&gt;
    &lt;meta http-equiv="X-UA-Compatible" content="IE=Edge"/&gt;
  
    &lt;video loop autoplay&gt; 
      &lt;source src="fito.ogg" type="video/ogg"&gt;    
      &lt;source src="fito.mp4" type="video/mp4"&gt;
      &lt;source src="fito.m4v" type="video/x-m4v"&gt;
    &lt;/video&gt;  
  </code></pre>
  
  <p>The first is the newest ogg and the second is legacy H.264 (IE 9 seems not playing the newer M4V). The last is m4v that no browser seems playing. Now all three major browsers do play the video just Safari does not and I have a requirement to support this one as well. Does anybody know how Safari is different from IE 9 in HTML 5 video support?</p>
