Track quality of experience on iOS

The following instructions provide guidance for implementation across all 2.x SDKs.

IMPORTANT

If you are implementing a 1.x version of the SDK, you can download the 1.x Developers Guides here: Download SDKs.

Implemement QOS

  1. Identify when the bitrate changes during media playback and create the MediaObject instance using the QoS information.

    QoSObject variables:

    Variable Description Required
    bitrate Current bitrate Yes
    startupTime Startup time Yes
    fps FPS value Yes
    droppedFrames Number of dropped frames Yes
    TIP

    These variables are only required if you are planning to track QoS.

    QoS object creation:

    id qosObject = [ADBMediaHeartbeat createQoSObjectWithBitrate:[BITRATE]
                                      startupTime:[STARTUP_TIME]  
                                      fps:[FPS]  
                                      droppedFrames:[DROPPED_FRAMES]];
    
  2. Make sure that getQoSObject method returns the most updated QoS information.

  3. When playback switches bitrates, call the BitrateChange event in the Media Heartbeat instance:

    - (void)onBitrateChange:(NSNotification *)notification {
        [_mediaHeartbeat trackEvent:ADBMediaHeartbeatEventBitrateChange  
                         mediaObject:nil  
                         data:nil];
    }
    
    IMPORTANT

    Update the QoS object and call the bitrate change event on every bitrate change. This provides the most accurate QoS data.
