Implement a custom opportunity detector

You can implement your own opportunity detectors.
  • If your opportunity generator is based on TimedMetadata objects associated with the current media stream, then it should extend the SpliceOutOpportunityGenerator or TimedMetadataOpportunityGenerator .
  • If your opportunity generator is based on out-of-band data provided by an external service (such as a CIS), then it should extend the OpportunityGenerator .
  1. Create the custom opportunity generator.
    If your custom opportunity generator is based on `TimedMetadata` objects, then extend the `TimedMetadataOpportunityGenerator` and override these methods:
    
    
    • doConfigure - This method is called after the media player item has been created and provides the opportunity generator to create an initial set of opportunities if needed
    • doProcess - This method is called every time new TimedMetadata is detected (for example, for live/linear streams every time the playlist/manifest refreshes)
    public class CustomOpportunityGenerator extends TimedMetadataOpportunityGenerator { 
        override protected function doConfigure(playhead:Number, playbackRange:TimeRange):void { 
            // the playhead represents the initial playback position 
            // the playback range represents the initial playback range 
    
            // the item property indicates the current MediaPlayerItem associated with this generator 
            // the initial set of timed metadata can be obtain through the item property 
            var timedMetadataCollection:Vector.<TimedMetadata> = item.timedMetadata; 
        } 
    
        override protected function doProcess(timedMetadata:TimedMetadata):void { 
            ... 
    
            // when an opportunity is created by this generator 
            // we need to notify the TVSDK through the client property 
            client.resolve(opportunity); 
        }  
        ... 
    }
    
    
  2. Create the custom content factory, which uses the custom opportunity generator.
    public class CustomContentFactory extends DefaultContentFactory { 
        ... 
    
        /** 
        * @inheritDoc 
        */ 
        override protected function doRetrieveGenerators(item:MediaPlayerItem):Vector.<OpportunityGenerator> { 
            var result:Vector.<OpportunityGenerator> = new Vector.<OpportunityGenerator>(); 
            result.push(new CustomOpportunityGenerator()); 
    
            return result; 
        } 
    }
    
    
  3. Register the custom content factory for the media stream to be played.
    var mediaPlayerItemConfig:MediaPlayerItemConfig = new DefaultMediaPlayerItemConfig(); 
    mediaPlayerItemConfig.advertisingFactory = new CustomContentFactory(); 
    ... 
    
    player.replaceCurrentResource(mediaResource, mediaPlayerItemConfig);
