The MediaBuilder assists in creating playlists of fully configurable MediaUnits, together with attached, configurable MediaOverlays, using JSON files or using a Dictionary, both following the same structure.

The media builder also has class methods that assist with the generation of individual MediaUnit and MediaOverlay objects from corresponding JSON or Dictionary structures.

Plugins can be attached to a media builder. Each plugin can dynamically insert, edit or remove units and/or overlays from the generated playlist.

In order to receive events, implement the IMediaPlayerTrackingEventHandler interface, and register the listener with the MediaPlayer.

Example:

             A. In your class:
             
Copy
public sealed partial class HubPage : Page , MediaPlayerTrackingEventHandler {

   public void onTrackingEventReceived(object sender , MediaPlayerEventArgs Event) {

     System.Diagnostics.Debug.WriteLine("Event = Type: " + Event.Type + " Message: " + Event.Message );
     if (Event.Type == MediaTrackingEvents.MediaEventType.FULLSCREEN)
         System.Diagnostics.Debug.WriteLine("Fullscreen entered");
else if (Event.Type == MediaTrackingEvents.MediaEventType.EXIT_FULLSCREEN)
         System.Diagnostics.Debug.WriteLine("Fullscreen exited");
}
            
             B. When initializing the player (or any time you wish to start receiving events):
             
Copy
MediaPlayer.getInstance().addTrackingEventHandler(this.onTrackingEventReceived);
             or
             
Copy
MediaPlayer.getInstance().PlayerEvent += onTrackingEventReceived;
             
             C. When you no longer want to receive events:
             
Copy
MediaPlayer.getInstance().removeTrackingEventHandler(this.onTrackingEventReceived);
             or
             
Copy
MediaPlayer.getInstance().PlayerEvent -= onTrackingEventReceived;
