Monitor QoS Statistics

You can monitor QoS statistics by using an NSTimer (or other methods) to scan the information provided by PTQOSProvider.

1. Create the PTQOSProvider instance. For example:

   qosProvider = [[PTQOSProvider alloc]initWithPlayer:self.player]; 
   PTDeviceInformation *devInfo = qosProvider.deviceInformation;
   if (devInfo) {
       [consoleView logMessage:@"=== qosDeviceInfo:==\n os =%@\n model = 
          %@\n id =%@\n\n", devInfo.os, devInfo.model, devInfo.id];
   }
   [NSTimer scheduledTimerWithTimeInterval:2.0 target:self 
      selector:@selector(printPlaybackInfoLog) userInfo:nil repeats:YES];
   
   

2. Read the values provided by the PTQOSProvider. For example:

   - (void)printPlaybackInfoLog {
       PTPlaybackInformation *playbackInfo = qosProvider.playbackInformation; 
       if (playbackInfo) {
           // For example:
           NSString *infoLog = [NSString stringWithFormat:@"observedBitrate : 
                                  %f\n",playbackInfo.observedBitrate];
           [consoleView logMessage:@"====%@\n\n",infoLog];
       }
   }
