Implement buffering

  1. Listen for the playback buffering events from media player, and on buffer start event notification, track buffering using the
    BufferStart
    event:
    - (void)onBufferStart:(NSNotification *)notification { [_mediaHeartbeat trackEvent:ADBMediaHeartbeatEventBufferStart mediaObject:nil data:nil]; }
  2. On buffer complete notification from the media player, track the end of buffering using the
    BufferComplete
    event:
    - (void)onBufferComplete:(NSNotification *)notification { [_mediaHeartbeat trackEvent:ADBMediaHeartbeatEventBufferComplete mediaObject:nil data:nil]; }
See the tracking scenario VOD playback with buffering for more information.
