title: Safari will not play mp4 over HTTPS
body: <p>I have a file, sample.html, which contains only the following code:</p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
      &lt;video width="600" autoplay loop poster="placeholder.jpg"&gt;
      &lt;source src="sample.mp4" /&gt;
      &lt;/video&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>The mp4 file referenced is the one downloaded from Apple: <a href="http://support.apple.com/kb/HT1425" rel="noreferrer">http://support.apple.com/kb/HT1425</a></p>
  
  <p>When I use Safari to access my page via <a href="http://myserver.com/sample.html" rel="noreferrer">http://myserver.com/sample.html</a> the video plays without problem.</p>
  
  <p>When I use Safari to access my page via <a href="https://myserver.com/sample.html" rel="noreferrer">https://myserver.com/sample.html</a> only the placeholder image is displayed.</p>
  
  <p>Details
  Safari 7.0.6
  Mac OS X 10.9.4</p>
  
  <p>I have used <a href="http://www.sslshopper.com/ssl-checker.html" rel="noreferrer">http://www.sslshopper.com/ssl-checker.html</a> to check that SSL is correctly configured for my domain and it reports no problems.</p>
  
  <p>How can I make the video play in Safari when accessed over https?</p>
