title: detect an error on html5 video
body: <p>I am trying to detect when there is an error on playing a video in html5. </p>
  
  <p>To be more specific, My use case is when one is trying to play an HLS video in MAC (so "canPlayType" is at least "maybe") - yet for some reason the video does not play. </p>
  
  <p>I have tried listening to 'error' event on the video tag. Doesn't work. In fact, the 'error' event is not even firing if I use an invalid url source!
  (See a demo here: <a href="http://mockup.on.aol.com/yogev/hls.html" rel="nofollow">http://mockup.on.aol.com/yogev/hls.html</a>)</p>
  
  <p>Could anyone please help? </p>
  
  <p>Thanks!</p>
