title: VLCKit on iOS has no fps when playing streaming
body: <p>When using mobileVLCKit.framework to play a live view streaming via RTSP protocol, I can't get fps info even if the displaying view is correctly shown.</p>
  
  <p>Here is my code</p>
  
  <pre><code>NSLog(@"%.1f FPS", self.player.framesPerSecond);
  </code></pre>
  
  <p>The result is always "0.0 FPS", and is not reasonable.</p>
  
  <p>I used framesPerSecond since fps is deprecated, as said in <a href="http://cocoadocs.org/docsets/MobileVLCKit/2.2.1/Classes/VLCMediaPlayer.html" rel="nofollow">http://cocoadocs.org/docsets/MobileVLCKit/2.2.1/Classes/VLCMediaPlayer.html</a></p>
  
  <p>Tracing to VLC source and I found</p>
  
  <pre><code>- (float)framesPerSecond
  {
      return libvlc_media_player_get_fps(_playerInstance);  
  }
  </code></pre>
  
  <p>it looks correct, but I still don't know why the result is wrong.</p>
  
  <p>Could someone give me suggestion or some work around method to get fps info?</p>
  
  <p>Any reply would be appreciated. Thanks!</p>
