Scenario

In questo scenario, l’istanza MediaHeartbeat viene utilizzata per creare due sessioni separate in sequenza.

Lo scenario è lo stesso di Riproduzione VOD senza annunci.

Parametri

Sessione heartbeat

Parametro Valore Note
s:event:sid ID di sessione univoco Un ID di sessione univoco presente in tutte le chiamate di rete heartbeat fino al trackSessionEnd

Codice di esempio

Android

Per creare due istanze di MediaHeartbeat per due lettori multimediali, imposta il seguente codice:

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);
}

Per visualizzare la prima sessione tramite l’istanza MediaAnalyticsProvider (quindi MediaHeartbeat) 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();

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

Per visualizzare la seconda sessione, puoi utilizzare la stessa istanza MediaAnalyticsProvider (MediaHeartbeat) come prima sessione, ma per una nuova sessione:

// 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();

iOS

Per creare due istanze di MediaHeartbeat per due lettori multimediali, immetti quanto segue:

@interface MediaAnalyticsProvider : NSObject <ADBMediaHeartbeatDelegate>

@end

@implementation {
  MediaPlayer *_player;
}

- (instancetype)initWithPlayer:(AVPlayer *)player {
  if (self = [super init]) {
      _player = player;

      ADBMediaHeartbeatConfig *config = [[ADBMediaHeartbeatConfig alloc] init];
      config.trackingServer = HEARTBEAT_TRACKING_SERVER;
      config.channel = HEARTBEAT_CHANNEL;
      config.appVersion = HEARTBEAT_SDK_VERSION;
      config.playerName = PLAYER_NAME;
      config.ssl = SSL_SETTING;
      config.debugLogging = DEBUG_SETTING;

      ADBMediaHeartbeatConfig *config = [[ADBMediaHeartbeatConfig alloc] init];
      _mediaHeartbeat = [[ADBMediaHeartbeat alloc] initWithDelegate:self config:config];

      [self setupPlayerNotifications];
  }

  return self;
}

- (ADBMediaObject *)getQoSInfo {
  return [ADBMediaHeartbeat createQoSObjectWithBitrate:CURRENT_BITRATE_VALUE
                            startupTime:CALCULATED_STARTED_TIME

                            droppedFrames:DROPPED_FRAMES_COUNT];
}

- (NSTimeInterval)getCurrentPlaybackTime {
  return CMTimeGetSeconds(_player.currentTime);
}

@end
- (void)viewDidAppear:(BOOL)animated {
  [super viewDidAppear:animated];
  [ADBMobile setDebugLogging:YES];

  // Setup the first media player
  NSURL *streamUrl = [NSURL URLWithString:CONTENT_URL];

  if (!self.mediaPlayer) {
      self.mediaPlayer = [[MediaPlayer alloc] initWithContentURL:streamUrl];
      //setup player
  }

  // Create the MediaAnalyticsProvider instance and attach it to the first
  // MediaPlayer instance.
  if (!self.mediaAnalyticsProvider) {
      self.mediaAnalyticsProvider =
        [[MediaAnalyticsProvider alloc] initWithPlayerDelegate:self.mediaPlayer];
  }
}

Per visualizzare la prima sessione utilizzando l’istanza MediaAnalyticsProvider (quindi MediaHeartbeat) in iOS, imposta il seguente codice:

                   streamType:ADBMediaHeartbeatStreamTypeVOD];

NSMutableDictionary *mediaContextData = [[NSMutableDictionary alloc] init];
[mediaContextData setObject:CUSTOM_VAL_1 forKey:CUSTOM_KEY_1];
[mediaContextData setObject:CUSTOM_VAL_2 forKey:CUSTOM_KEY_2];

// 1. Call trackSessionStart when the user clicks Play or if autoplay is used,
//    i.e., there's an intent to start playback.
[_mediaHeartbeat trackSessionStart:mediaObject data:mediaContextData];
.......
.......

// 2. Call trackPlay when the playback actually starts, i.e., when the first
//    frame of the 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.
