多个并行的 VOD 跟踪器

方案

在此方案中,针对两个不同的媒体以并行方式运行了两个会话,这两个会话使用两个不同的 MediaHeartbeat 实例。

此方案与不含广告的 VOD 播放方案相同,不同之处在于此方案针对两个不同的媒体以并行方式运行了两个会话。这两个会话分别使用不同的 MediaHeartbeat 实例。

除非另外指定,否则网络调用与不含广告的 VOD 播放方案相同。

参数

心率会话

参数 注释
s:event:sid 唯一的会话 ID 唯一的会话 ID 一直存在于所有心率网络调用中,直到调用 trackSessionEnd 方法。

示例代码

Android

public class MediaAnalyticsProvider implements MediaHeartbeatDelegate { 
  private MediaPlayer _player; 
  private MediaHeartbeat _heartbeat; 

  public MediaAnalyticsProvider(MediaPlayer player) { 
      if (player == null) { 
          throw new IllegalArgumentException("Player reference cannot be null."); 

      } 
      _player = player;  
      _player.addObserver(this); 

      // Media Heartbeat initialization 
      MediaHeartbeatConfig config = new MediaHeartbeatConfig(); 
      config.trackingServer = HEARTBEAT_TRACKING_SERVER; 
      config.channel = HEARTBEAT_CHANNEL; 
      config.appVersion = HEARTBEAT_SDK; 
      config.ovp = HEARTBEAT_OVP; 
      config.playerName = PLAYER_NAME; 
      config.ssl = false; 
      config.debugLogging = true;  

      _heartbeat = new MediaHeartbeat(this, config); 
  } 

  @Override 
  public MediaObject getQoSObject() { 
      return MediaHeartbeat.createQoSObject(BITRATE,  
                                            STARTUP_TIME,  
                                            FPS,  
                                            DROPPED_FRAMES); 
  } 

  @Override 
  public Double getCurrentPlaybackTime() { 
      return _player.getCurrentPlaybackTime(); 
  } 
} 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
  super.onCreate(savedInstanceState); 
  setContentView(R.layout.activity_main); 

  // Bootstrap the AdobeMobile library.  
  Config.setContext(this.getApplicationContext()); 

  // Create first MediaPlayer instance.  
  _player1 = new MediaPlayer(); 

  // Create first MediaAnalyticsProvider instance and 
  // attach it to the MediaPlayer instance.  
  _analyticsProvider1 = new MediaAnalyticsProvider(_player1); 

  // Load the main media content.  
  Uri uri =  
    Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.media1);  
  _player1.loadContent(uri); 

  // Create second MediaPlayer instance.  
  _player2 = new MediaPlayer(); 

  // Create second MediaAnalyticsProvider instance and 
  // attach it to the MediaPlayer instance.  
  _analyticsProvider2 = new MediaAnalyticsProvider(_player2); 

  // Load the main media content.  
  Uri uri =  
    Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.media2);  
  _player2.loadContent(uri); 
} 

MediaAnalyticsProviderMediaHeartbeat 的实例都跟踪两个不同的会话,每个会话具有自己唯一的会话 ID。在 Charles 调试工具或调试日志中,这两个会话可以通过使用会话 ID 值进行识别。要在 Android 中显示此方案,请设置以下代码:

// Set up mediaObject 
MediaObject mediaInfo = MediaHeartbeat.createMediaObject( 
  Configuration.MEDIA_NAME,  
  Configuration.MEDIA_ID, 
  Configuration.MEDIA_LENGTH,  
  MediaHeartbeat.StreamType.VOD 
); 

HashMap<String, String> mediaMetadata = new HashMap<String, String>(); 
mediaMetadata.put(CUSTOM_VAL_1, CUSTOM_KEY_1); 
mediaMetadata.put(CUSTOM_VAL_2, CUSTOM_KEY_2); 

// 1. Call trackSessionStart() when the user clicks Play or if autoplay is used,  
//    i.e., there is an intent to start playback. 
_mediaHeartbeat.trackSessionStart(mediaInfo, mediaMetadata); 

...... 
...... 

// 2. Call trackPlay() when the playback actually starts, i.e., when the first  
//    frame of main content is rendered on the screen.  
_mediaHeartbeat.trackPlay(); 

....... 
....... 

// 3. Call trackComplete() when the playback reaches the end, i.e., when the 
//    media completes and finishes playing.  
_mediaHeartbeat.trackComplete(); 

........ 
........ 

// 4. Call trackSessionEnd() when the playback session is over. This method must  
//    be called even if the user does not watch the media to completion. 
_mediaHeartbeat.trackSessionEnd();
