    Android: Working with Media Content

    In this topic, you will learn how to retrieve and play your videos using the Native SDK for Android.

    Overview

    Video Cloud customers have access to their media data and metadata from Video Cloud Studio. Brightcove Player customers will supply the URL for their media content.

    Video Cloud customers

    As a Video Cloud customer, you can access your media data stored in Video Cloud Studio. For more information, see the Player SDK for Android code samples.

    Retrieving media data

    You can retrieve your video and playlist data from your Video Cloud library by using the Playback API. For details about the API, see the Playback API Overview document.

    1. Use the com.brightcove.player.edge.Catalog class methods to retrieve your videos and playlists from Brightcove's Playback API. Your requests can supply the video/playlist ID or ReferenceID. This service will make the URL requests and parse the returned data.

    2. For this request, you will need a Policy Key. If you are not familiar with Policy Keys, see the Policy API Overview document.

      Here is an example of how to retrieve a video using the com.brightcove.player.edge.Catalog class:

      package com.brightcove.player.samples.exoplayer.basic;
      import android.os.Bundle;
      import android.util.Log;
      import com.brightcove.player.edge.Catalog;
      import com.brightcove.player.edge.VideoListener;
      import com.brightcove.player.event.EventEmitter;
      import com.brightcove.player.model.Video;
      import com.brightcove.player.view.BrightcoveExoPlayerVideoView;
      import com.brightcove.player.view.BrightcovePlayer;
      /**
      * This app illustrates how to use the ExoPlayer with the Brightcove
      * Native Player SDK for Android.
      */
      public class MainActivity extends BrightcovePlayer {
      	private final String TAG = this.getClass().getSimpleName();
      	@Override
      
      	protected void onCreate(Bundle savedInstanceState) {
      		setContentView(R.layout.activity_main);
      		brightcoveVideoView = (BrightcoveExoPlayerVideoView) findViewById(R.id.brightcove_video_view);
      		super.onCreate(savedInstanceState);
      
      		// Get the event emitter from the SDK and create a catalog request to fetch a video from the
      		// Brightcove Edge service, given a video id, an account id and a policy key.
      		EventEmitter eventEmitter = brightcoveVideoView.getEventEmitter();
      		Catalog catalog = new Catalog(eventEmitter, getString(R.string.account), getString(R.string.policy));
      
      		catalog.findVideoByID(getString(R.string.videoId), new VideoListener() {
      		  // Add the video found to the queue with add().
      		  // Start playback of the video with start().
      		  @Override
      		  public void onVideo(Video video) {
      		    Log.v(TAG, "onVideo: video = " + video);
      		    brightcoveVideoView.add(video);
      		    brightcoveVideoView.start();
      		  }
      		});
      	}
      }
    1. The Video object provides methods to retrieve media information as shown below:
      catalog.findVideoByID(getString(R.string.videoId), new VideoListener() {
        // Add the video found to the queue with add().
        // Start playback of the video with start().
        @
        Override
        public void onVideo(Video video) {
          Log.v(TAG, "onVideo: video = " + video);
          Log.v(TAG, "onVideo: videoID = " + video.getId());
          Log.v(TAG, "onVideo: videoName = " + video.getName());
          Log.v(TAG, "onVideo: videoDescription = " + video.getDescription());
          Log.v(TAG, "onVideo: videoImage = " + video.getStillImageUri());
          Log.v(TAG, "onVideo: sourceCollections = " + video.getSourceCollections());
          SourceCollection dashCollection = video.getSourceCollections().get(DeliveryType.DASH);
          if (dashCollection != null) {
            Set < Source > sources = dashCollection.getSources();
            for (Source source: sources) {
              if (!TextUtils.isEmpty(source.getUrl())) {
                Log.v(TAG, "onVideo: DASH source = " + source.getUrl());
              }
            }
          }
      
          brightcoveVideoView.add(video);
          brightcoveVideoView.start();
        }
      });

      The above Log() methods return the following media information:

      Video object
      Video object
    2. You may want to see the custom fields, if any, exist for the Video object. Add the following code to the onVideo callback method to loop through the customField map.

        catalog.findVideoByID(getString(R.string.videoId), new VideoListener() {
         @
         Override
         public void onVideo(Video video) {
            Map<String, String> customFieldMap = (HashMap<String, String>) video.getProperties().get(Video.Fields.CUSTOM_FIELDS);
           if (customFieldMap != null && customFieldMap.size() > 0) {
             for (Map.Entry<String, String> entry : customFieldMap.entrySet()) {
               Log.v(TAG, "onVideo: Custom fields: Key: " + entry.getKey() + " Value: " + entry.getValue());
             }
           }
           brightcoveVideoView.add(video);
           brightcoveVideoView.start();
        }
      });

      Here is an example of the logged output you may see from the code above:

      MainActivity: onVideo: Custom fields: Key: genre Value: Action
      MainActivity: onVideo: Custom fields: Key: customlist Value: customListValue1

      Note that custom fields can be represented as Strings or Lists. Even though a custom field can be a List type, it is a list of String values from which one value is chosen to set the field's value.

    Geo-filtered videos

    The Brightcove Player SDK for Android supports geo-filtered videos.

    There are two ways you can add geo-filtering to your videos to control which countries they can (or cannot) be viewed in:

    In your Android app, when you retrieve a video using Brightcove's edge Catalog object (Playback API) in a country which is geo-filtered for that video, you should see this message:

    error { message: Access to this resource is forbidden by access policy.
    client_geo: us
    error_subcode: CLIENT_GEO
    error_code: ACCESS_DENIED }

    Brightcove Player customers

    As a Brightcove Player customer, you will supply the URL for your video assets.

    Here is an example of adding a video to your video view and starting playback:

    import com.brightcove.player.model.DeliveryType;
    import com.brightcove.player.model.Video;
    import com.brightcove.player.view.BrightcoveExoPlayerVideoView;
    import com.brightcove.player.view.BrightcovePlayer;
    import com.brightcove.player.analytics.Analytics;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    	super.onCreate(savedInstanceState);
    	setContentView(R.layout.activity_main);
    	BrightcoveVideoView brightcoveVideoView = (BrightcoveVideoView) findViewById(R.id.brightcove_video_view);
    
    	Analytics analytics = brightcoveVideoView.getAnalytics();
    	analytics.setAccount("123456789");
    
    	MediaController controller = new MediaController(this);
    	brightcoveVideoView.setMediaController(controller);
    	brightcoveVideoView.add(Video.createVideo("http://solutions.brightcove.com/bcls/assets/videos/Bird_Titmouse.mp4", DeliveryType.MP4));
    	brightcoveVideoView.start();
    }
     

    Next, let's take a look at how events work within the SDK architecture.
