Tracciamenti multipli VOD in parallelo

Scenario

In questo scenario, ci sono due sessioni in esecuzione in parallelo per due media separati e utilizzando due istanze separate di MediaHeartbeat.

Questo scenario è identico alla riproduzione VOD senza scenari di annunci, ad eccezione delle due sessioni in esecuzione parallela per due supporti separati. Ciascuna di queste sessioni utilizza un'istanza separata di MediaHeartbeat.

Se non specificato, le chiamate di rete sono uguali alla riproduzione VOD senza annunci scenario.

Parametri

sessione Heartbeat

Parametro Valore Note
s:event:sid ID sessione univoco Un ID di sessione univoco presente in tutte le chiamate di rete heartbeat fino a quando non viene chiamato il metodo trackSessionEnd .

Codice di esempio

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); 
} 

Entrambe le istanze di MediaAnalyticsProvider e MediaHeartbeat tengono traccia di due sessioni separate, ciascuna con i propri ID di sessione univoci. Le due sessioni nello strumento di debug Charles o nei registri di debug possono essere identificate utilizzando il valore ID sessione. Per visualizzare questo scenario in Android, imposta il seguente codice:

// 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();
