title: AVQueuePlayer not advancing to next item in iOS 8
body: <p>I am using AVQueuePlayer to play a few videos, everything works fine in iOS 6 &amp; 7. However, in iOS 8, when the current AVPlayerItem finishes playing the next video does not play. Placing an observer on the queue's currentItem property shows the the queue has the next video set as its current item as expected, it just does not play (even with explicit play calls). </p>
  
  <p>Does anyone have any insight into what might be happening and how to fix it? Has anyone else come across this issue? </p>
