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 instantiating a MediaPlayer instance.

Through the MediaPlayerItemLoader class, you can exchange a media resource for the corresponding MediaPlayerItem without attaching a view to a MediaPlayer instance, which would lead to the allocation of the video decoding hardware resources. The process of obtaining the MediaPlayerItem instance is asynchronous.

  1. Implement the MediaPlayerItemLoader.LoaderListener callback interface.

    This interface defines two methods:
    • LoaderListener.onError callback function

      TVSDK uses this to inform your application that an error has occurred. TVSDK provides an error code as parameters and a description string that contains diagnostic information.

    • LoaderListener.onError callback function

      TVSDK uses this to inform your application that the requested 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 TVSDK 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. For example:

    // instantiate the listener interface 
    MediaPlayerItemLoader.LoaderListener _itemLoaderListener = 
      new MediaPlayerItemLoader.LoaderListener() { 
        public void onError(MediaErrorCode mediaErrorCode, String description) { 
            // something went wrong - look at the error code and description 
            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("https://test.com/test_media.m3u8", null); 
    // load the media resource
