Un dispositif de suivi VOD pour plusieurs sessions

Scénario

Dans ce scénario, l’instance MediaHeartbeat est utilisée pour créer deux sessions distinctes en séquence.
Ce scénario est le même que le scénario lecture VOD sans publicité .

Exemple de code

Android

Pour créer deux instances de MediaHeartbeat pour deux lecteurs multimédia, configurez le code suivant :
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 AppMeasurement library.  
  Config.setContext(this.getApplicationContext()); 

  // Create the MediaPlayer instance.  
  _player = new MediaPlayer(); 

  // Create the MediaAnalyticsProvider instance and 
  // attach it to the MediaPlayer instance.  
   _analyticsProvider = new MediaAnalyticsProvider(_player); 

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

Pour afficher la première session à l’aide de l’instance MediaAnalyticsProvider ( MediaHeartbeat ) dans Android, définissez le code suivant :
// 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(); 

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

Pour afficher la deuxième session, vous pouvez utiliser la même instance MediaAnalyticsProvider ( MediaHeartbeat ) que pour la première session, mais pour une nouvelle session :
// 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();
