title: iOS - AVPlayer using closedcaptions
body: <p>I'm working with AVPlayer on iOS use to "closedCaptionDisplayEnabled  property"
   to show captions or subtitle on the movie (hls or mp4), but the caption not show anything.
  I don't know why?</p>
  
  <p>Have you any solution to show captions(subtitle) on movie(hls,mp4)?</p>
  
  <p>And i see a few sample about app, youtube, netflix, tvguide and something used to closed caption. </p>
  
  <p>Maybe all the app on iphone, ipad from netflix,youtube using one file and insert subtitle inside video, i think</p>
  
  <p>But, i want to use to two file (one file hls or mp4, one file srt or WebVTT)</p>
