title: VideoJS + HTML5 mp4 video used to work on iOS, now does not (iOS5)
body: <p>I have a webpage with a bunch of embedded html5 video widgets driven by VideoJS. </p>
  
  <p>It currently works in all major browsers and iOS4, including Windows safari 5.1.7.</p>
  
  <p>with iOS5, the html5 video appears with a play button with a line through it. </p>
  
  <p>playing the video via direct link works just fine in iOS5, but the embedded versions show up with that play button crossed out...</p>
  
  <p>Anyone know what the deal is with new iOS that prevents HTML5 mp4 videos from no longer playing back? </p>
  
  <p>iOS4 safari play the embedded video as expected...</p>
