Implement a custom content resolver

You can implement your own content resolvers based on the default resolvers.

When TVSDK generates a new opportunity, it iterates through the registered content resolvers looking for one that is capable of resolving that opportunity. The first one that returns true is selected to resolve the opportunity. If no content resolver is capable, that opportunity is skipped. Because the content resolving process is usually asynchronous, the content resolver is responsible for notifying TVSDK when the process has completed.

1. Implement your own custom ContentFactory, by extending the ContentFactory interface and overriding retrieveResolvers.

   For example:

   class MyContentFactory extends ContentFactory {
       @Override
       public List<ContentResolver> retrieveResolvers(MediaPlayerItem item) {
           List<ContentResolver> resolvers = new ArrayList<ContentResolver>();
           MediaPlayerItemConfig itemConfig = item.getConfig();
           if(itemConfig) {
               CustomRangeMetadata customRanges = itemConfig.getCustomRangeMetadata();
               if (customRanges) {
                   List<ReplaceTimeRange> timeRanges = customRanges.getTimeRangeList();
   
                   if (timeRanges && timeRanges.size() > 0)
                   {
                   // CustomRangeResolver is only activated by the presence of CustomRanges in configuration
                   resolvers.add(new CustomRangeResolver());
                   }
               }
               AdvertisingMetadata metadata = itemConfig.getAdvertisingMetadata();
               if (metadata) {
                   if (metadata instanceOf AuditudeSettings)
                       resolvers.add(new AuditudeResolver(getContext());
                   }
               }
           // add your custom resolver if any
           resolvers.add(MyOpportunityGenerator(item));
           return resolvers;
       }
       ...
   }
   
   

2. Register the ContentFactory to the MediaPlayer.

   For example:

   //Register the custom content factory with the media player
   MediaPlayerItemConfig config = new MediaPlayerItemConfig();
   config.setAdvertisingFactory(new MyContentFactory());
   
   //Pass this config while loading the resource
   mediaPlayer.replaceCurrentResource(resource, config);
   
   // OR use MediaPlayerItemLoader to pre-load a resource
   id = 23;
   itemLoader.load(resource, id, config);
   

3. Pass an AdvertisingMetadata object to TVSDK as follows:

   1. Create an AdvertisingMetadata object.

   2. Save the AdvertisingMetadata object to MediaPlayerItemConfig.

      AdvertisingMetadata advertisingMetadata = new AdvertisingMetadata();
      
      advertisingMetadata.setDelayAdLoading(true);
      ...
      
      mediaPlayerItemConfig.setAdvertisingMetadata(advertisingMetadata);
      
      

4. Create a custom ad resolver class that extends the ContentResolver class.

   1. In the custom ad resolver, override doConfigure, doCanResolve, doResolve, doCleanup:

      void doConfigure(MediaPlayerItem item);
      boolean doCanResolve(Opportunity opportunity);
      void doResolve(Opportunity opportunity);
      void doCleanup();
      

      You get your advertisingMetadata from the item passed in doConfigure:

      MediaPlayerItemConfig itemConfig = item.getConfig();
      
      AdvertisingMetadata advertisingMetadata =
        mediaPlayerItemConfig.getAdvertisingMetadata();
      
      

   2. For each placement opportunity, create a List<TimelineOperation>.

      This sample TimelineOperation provides a structure for AdBreakPlacement:

      AdBreakPlacement(
          new AdBreak( ads,    // Vector<Ad>
                       tracker // Content Tracker
          ),
          placementInformation // Retrieved from Opportunity
      );
      
      

   3. After ads are resolved, call one of the following functions:

      • If the ad resolve succeeds, call process(List<TimelineOperation> proposals) and notifyCompleted(Opportunity opportunity) on the ContentResolverClient

        _client.process(timelineOperations);
        _client.notifyCompleted(opportunity);
        
        

      • If the ad resolve fails, call notifyResolveError on the ContentResolverClient

        _client.notifyFailed(Opportunity opportunity, PSDKErrorCode error);
        

        For example:

        _client.notifyFailed(opportunity, UNSUPPORTED_OPERATION);
        

This sample custom ad resolver resolves an opportunity and serves a simple ad:

public class CustomContentResolver extends ContentResolver {
    protected void doConfigure(MediaPlayerItem item){}

    protected boolean doCanResolve(Opportunity opportunity) {
        return true;
    }

    protected void doResolve(Opportunity opportunity) {
        _client.process(createAdBreakPlacementsFor(opportunity.getPlacement()));
        _client.notifyCompleted(opportunity);
    }

    private List<TimelineOperation> createAdBreakPlacementsFor(Placement placementInformation) {
        List<Ad> ads = new ArrayList<Ad>();
        AdAsset adAsset = new AdAsset("101", 15000, new MediaResource(
          "https: . . ..m3u8", MediaResource.Type.HLS, null), null, null);

        Ad ad = Ad.linearFromAsset("101", adAsset, null, null, false);
        ads.add(ad);
        AdBreak adBreak = new AdBreak(ads, null, AdInsertionType.CLIENT_INSERTED);

        List<TimelineOperation> result = new ArrayList<TimelineOperation>();

        result.add(new AdBreakPlacement(placementInformation, adBreak));
        return result;
    }

    protected void doCleanup() {}
}
