title: videojs disable black background
body: <p>videojs (v3.2.0) always shows a black background, when loading the video in swf mode. 
  Does someone know how to change that? </p>
  
  <p>You can add swf params like that to the player:</p>
  
  <pre><code>var params = {};
  params.bgcolor = "#ffffff";
  params.wmode = "transparent";
  </code></pre>
  
  <p><em>V</em>.options.flash.params = params;</p>
  
  <p>With wmode = "transparent" you can see a black box in the top left corner. 
  On IE7/8 the box does not disappear when playing the video and shows up as a black line around the video (like a black border-top).</p>
  
  <p>Many thanks,
  Florian</p>
