Implement a custom opportunity/content resolver
You can implement your resolvers based on the default resolvers.
- Develop a custom ad resolver by extending the PTContentResolver abstract class.PTContentResolver is an interface that must be implemented by a content resolver class. An abstract class with the same name is also available and handles the configuration automatically (getting the delegate).PTContentResolver is exposed through the PTDefaultMediaPlayerClientFactory class. Clients can register a new content resolver by extending the PTContentResolver abstract class. By default, and unless specifically removed, a PTDefaultAdContentResolver is registered in the PTDefaultMediaPlayerClientFactory .
@protocol PTContentResolver <NSObject> @required + (BOOL)shouldHandleOpportunity:(PTPlacementOpportunity *)opportunity; //Detector returns YES/NO if it should handle the following placement opportunity - (void)configWithPlayerItem:(PTMediaPlayerItem *)item delegate:(id<PTContentResolverDelegate> delegate); - (void)process:(PTPlacementOpportunity *)opportunity; - (void)timeout:(PTPlacementOpportunity *)opportunity; //The timeout method gets invoked if the TVSDK decides that the //PTContentResolver is taking too much time to respond. @end @interface PTContentResolver : NSObject <PTContentResolver> @property (readonly) id<PTContentResolverDelegate> delegate; @property (readonly) PTMediaPlayerItem *playerItem; - (BOOL)shouldHandleOpportunity:(PTPlacementOpportunity *)opportunity; - (void)configWithPlayerItem:(PTMediaPlayerItem *)item delegate:(id<PTContentResolverDelegate>) delegate; - (void)process:(NSArray *)opportunities; - (void)cancel:(NSArray *)opportunities; @end
- Implement shouldResolveOpportunity and return YES if it should handle the received PTPlacementOpportunity .
- Implement resolvePlacementOpportunity , which starts loading the alternate content or ads.
- After the ads are loaded, prepare a PTTimeline with the information about the content to insert.
Here is some useful information about timelines:
- There can be multiple PTAdBreak s of pre-roll, mid-roll, and post-roll types.
- A PTAdBreak has the following:
- A CMTimeRange with the start time and duration of the break.This is set as the range property of PTAdBreak .
- NSArray of PTAd s.This is set as the ads property of PTAdBreak .
- A PTAd represents the ad, and each PTAd has the following:
- A PTAdHLSAsset set as the primary asset property of the ad.
- Possibly multiple PTAdAsset instances as clickable ads or banner ads.
NSMutableArray *ptBreaks = [[[NSMutableArray alloc] init] autorelease]; // Prepare the primary asset of the ad - links to ad m3u8 PTAdHLSAsset *ptAdAsset = [[[PTAdHLSAsset alloc] init] autorelease]; ptAdAsset.source = AD_SOURCE_M3U8; ptAdAsset.id = FAKE_NUMBER_ID; ptAdAsset.format = @"video"; // Prepare the ad itself. PTAd *ptAd = [[[PTAd alloc] init] autorelease]; ptAd.primaryAsset = ptAdAsset; ptAd.primaryAsset.ad = ptAd; // Prepare the break and add the ad created above. PTAdBreak *ptBreak = [[[PTAdBreak alloc] init] autorelease]; ptBreak.relativeRange = CMTimeRangeMake(BREAK_START_TIME, BREAK_DURATION_VALUE); [ptBreak addAd:ptAd]; // Add the break to array of breaks. [ptBreaks addObject:adBreak]; // Once all breaks have been prepared, they can be set on timeline PTTimeline *_timeline = [[PTTimeline alloc] init]; _timeline.adBreaks = ptBreaks;
- Call didFinishResolvingPlacementOpportunity , which provides the PTTimeline .
- Register your custom content/ad resolver to the default media player factory by calling registerContentResolver .
//Remove default content/ad resolver [[PTDefaultMediaPlayerFactory defaultFactory] clearContentResolvers]; //Create an instance of your content/ad resolver (id <PTContentResolver>) CustomContentResolver *contentResolver = [[CustomContentResolver alloc] init]; //Set custom content/ad resolver [[PTDefaultMediaPlayerFactory defaultFactory] registerContentResolver:[contentResolver autorelease]];
- If you implemented a custom opportunity resolver, register it to the default media player factory.You do not have to register a custom opportunity resolver to register a custom content/ad resolver.
//Remove default opportunity resolver [[PTDefaultMediaPlayerFactory defaultFactory] clearOpportunityResolvers]; //Create an instance of your opportunity resolver (id <PTOpportunityResolver>) CustomOpportunityResolver *opportunityResolver = [[CustomOpportunityResolver alloc] init]; //Set custom opportunity resolver [[PTDefaultMediaPlayerFactory defaultFactory] registerOpportunityResolver:[opportunityResolver autorelease]];
When the player loads the content, and it is determined to be of type VOD or LIVE, one of the following occurs: >
- If the content is VOD, the custom content resolver is used to get the ad timeline of the entire video.
- If the content is LIVE, the custom content resolver is called each time a placement opportunity (cue point) is detected in the content.
