Load a media resource in the media player

Load a resource by directly instantiating a MediaResource and loading the video content to be played. This is one way of loading a media resource.

1. Set the media player to play the new resource.

   Replace the currently playable item by calling MediaPlayer.replaceCurrentResource() and passing an existing MediaResource instance.

   This starts the resource loading process.

2. Register the MediaPlayerEvent.STATUS_CHANGED event with the MediaPlayer instance. In the callback, check for at least the following status values:

   • MediaPlayerStatus.PREPARED
   • MediaPlayerStatus.INITIALIZED
   • MediaPlayerStatus.ERROR

   Through these events, the MediaPlayer object notifies your application when it has successfully loaded the media resource.

3. When the status of the media player changes to INITIALIZED, you can call MediaPlayer.prepareToPlay().

   This status indicates that the media has been successfully loaded. The new MediaPlayerItem is ready for playback. Calling prepareToPlay() starts the advertising resolution and placement process, if any.

If a failure occurs, the media player switches to the ERROR status.

The following simplified sample code illustrates the process of loading a media resource:

// mediaResource is a properly configured MediaResource instance
// mediaPlayer is a MediaPlayer instance
// register a PlaybackEventListener implementation with the MediaPlayer instance
mediaPlayer.addEventListener(MediaPlayerEvent.STATUS_CHANGED,
  new StatusChangeEventListener() {
    @Override
    public void onStatusChanged(MediaPlayerStatus status) {
        if(event.getStatus() == MediaPlayerStatus.PREPARED) {
            // The resource is successfully loaded and available. The
            // MediaPlayer is ready to start the playback and can
            // provide a reference to the current playable item
            MediaPlayerItem playerItem = mediaPlayer.getCurrentItem();
            if (playerItem != null) {
                // We can look at the properties of the loaded stream
            }
        }
        else if (event.getStatus() == MediaPlayerStatus.ERROR) {
            //Something bad happened - the resource cannot be loaded.
            // The Metadata object in the event provides details.
        }
        else if (status == MediaPlayerStatus.INITIALIZED) {
            mediaPlayer.prepareToPlay();
        }
    }
}
