title: How to set buffer and download cache in local to play offline from .PLS file in AVPlayer?
body: <p>AVPlayer is playing .pls file perfectly but now need to extend support with offline cache and play them offline. I want to set Buffer Values like (200KB, 500KB, 1MB) to download streaming cache in local iOS directory and play them offline. </p>
  
  <p>Code for Playing:</p>
  
  <pre><code>myplayerItem = AVPlayerItem(url: url as! URL)
  myPlayer = AVPlayer(playerItem: myplayerItem)
  myPlayer.play();
  </code></pre>
  
  <p>Please Note: This .pls file contain only audio data and no video data. While open the pls file in text editor it looks like below:</p>
  
  <pre><code>[playlist]
  numberofentries=1
  File1=http://server.com:8085/stream
  Title1=somename
  Length1=-1
  version=2
  </code></pre>
  
  <p>Please share your experience for above. is it possible in iOS or not?</p>
