• click '+' sign and add "NielsenAppApi.Framework" and "JWPlayer-iOS-SDK.framework"
• Build the app within the plugin

Nielsen App SDK Plugin Creation

The Nielsen App SDK Plugin for JWPlayer integrates with the JWPlayer SDK by listening for events from the player, other plugins and emits events for the player. It is also a wrapper for the Nielsen App SDK. It is registered with the JWPlayer SDK when it is instantiated by the application.

Perform the following steps in the app view controller, where the player is initialized

• Import Plugin

  #import "NielsenJWPlayerPlugin.h"</syntaxhighligh>
  * Add Property<syntaxhighlight lang="objective-c">@property (nonatomic, strong) NielsenJWPlayerPlugin *nielsenJWPlayerPlugin;
  

  Instantiate the plugin and register it with an instance of 'JWPlayerController' based on the app information provided by Nielsen.

  self.nielsenJWPlayerPlugin = [[NielsenJWPlayerPlugin alloc]
  initWithAppInfo:@{@"appid": @"MY_APP_ID",
                              @"appversion": @"MY_APP_VERSION",
                              @"appname": @"MY_APP_NAME",
                              @"sfcode": @"MY_SFCODE"};
  self.nielsenJWPlayerPlugin.dataSource = self;
  self.player.delegate = self.nielsenJWPlayerPlugin;
  

• Implement 'NielsenJWPlayerDataSource' delegate by adding the method as mentioned below:

  – (NSDictionary *)contentMetadata;
  

  Plugin will call this method to fetch content metadata for the video.

Refer to the Reference Guide in the Nielsen SDK Documentation on the exact format of this dictionary. Set any key-value pair from the content metadata with an exception of 'length', 'type' and 'title', which are pre-set already.

• Add the following line of code (optional):

  – (NSDictionary *)channelInfo;
  

Plugin calls this method to request for channel information associated with the video.

Refer to the Onboarding Process in the Nielsen SDK Documentation on the exact format of this dictionary.

• Add the following line of code to notify App SDK that the remote OTT device (like Google ChromeCast, Roku, Amazon FireTV, etc.) is connected / disconnected (change of OTT status).

Refer to the Onboarding Process in the Nielsen SDK Documentation for more information and example.

Opt-Out

The app needs to provide a way for the user to optout of metering. This is done by displaying Opt-Out page and passing the user's response back to Nielsen, as described in the Onboarding Process of the Nielsen SDK Documentation. The plugin exposes the 'NielsenAppApi', userOptOut and optOutURLString methods that are needed to interact with Opt-Out page.

-(BOOL)optOutStatus;

This API gets the current Nielsen opt-out state of AppSDK. Call this API to retrieve the Opt-Out or Opt-In state. Refer to the Onboarding Process in the Nielsen SDK Documentation for more information and example.

SampleApp

Check NielsenJWPlayerSampleApp (NielsenJWPlayerSampleApp.tar.gz) to know about the usage of plugin and the Opt-Out page.
