title: Magnific Popup - Error when opening a you tube video
body: <p>Can not get a video to play in the magnific pop up window. 
  When I use <code>class=iframe</code>, the page will redirect to youtube and play the video. 
  But when I use <code>class=popup-youtube</code>, the popup will display, but I receive the following error message: </p>
  
  <p>This webpage is not found</p>
  
  <pre><code>No webpage was found for the web address: file://www.youtube.com/embed/AcnImfXjBHo?autoplay=1
  Error 6 (net::ERR_FILE_NOT_FOUND): The file or directory could not be found.
  </code></pre>
  
  <p>Here is the HTML code:</p>
  
  <pre><code>&lt;a class="popup-YouTube" href="HTTP://www.youtube.com/watch?v=AcnImfXjBHo"&gt;
                                  Trial Master File Video&lt;/a&gt;    
  </code></pre>
  
  <p>Here is the JS:</p>
  
  <pre><code>$(document).ready(function() {
          $('.popup-youtube, .popup-vimeo, .popup-gmaps').magnificPopup({
              disableOn: 700,
              type: 'iframe',
              mainClass: 'mfp-fade',
              removalDelay: 160,
              preloader: false,
  
              fixedContentPos: false
          });
      });
  </code></pre>
  
  <p>I am running this locally on my PC through IIS for testing. My other links that I set up for single images, gallery images and a google map work fine with magnific pop up. The video is the only one not working.</p>
