Load a media resource using MediaPlayerItemLoader

Another way to resolve a media resource is with MediaPlayerItemLoader. This is useful when you want to obtain information about a particular media stream without the full instantiation of a MediaPlayer instance.

1. Implement the MediaPlayerItemLoader.LoaderListener callback interface. This interface defines two methods:
   • LoaderListener.onError callback function: The PSDK uses this to inform your application that an error has occurred. The PSDK provides as parameters an error code and a description string that contains diagnostic information.
   • LoaderListener.onLoadComplete callback function: The PSDK uses this to inform your application that the desired information is available in the form of a MediaPlayerItem instance that is passed on as a parameter to the callback.
2. Register this instance to the PSDK by passing it as a parameter to the constructor of the MediaPlayerItemLoader.
3. Call MediaPlayerItemLoader.load, passing an instance of a MediaResource object. The URL of the MediaResource object must point to the stream for which you want to obtain information. Here is an example:

   // instantiate the listener interface
   MediaPlayerItemLoader.LoaderListener _itemLoaderListener =
           new MediaPlayerItemLoader.LoaderListener() {
   @Override
   public void onError(MediaErrorCode mediaErrorCode, String description) {
       // something went wrong - look at the error code and description
   }
   @Override
   public void onLoadComplete(MediaPlayerItem playerItem) {
       // information is available - look at the data in the "playerItem" object
   }
   }
   // instantiate the MediaPlayerItemLoader object (pass the listener as parameter)
   MediaPlayerItemLoader itemLoader = new MediaPlayerItemLoader(_itemLoaderListener);
   // create the MediaResource instance and set the URL to point to the actual media stream
   MediaResource mediaResource = MediaResource.createFromUrl("http://example.com/media/test_media.m3u8", null);
   // load the media resource
   itemLoader.load(mediaResource);
