Client Side Ad Insertion

The FLAdvertisingGoogleIMA library integrates with GoogleIMA to offer Client Side Ad Insertion capability for both VOD and Live.

GoogleIMA

Supported GoogleIMA SDK version

• iOS 3.14.5
• tvOS 4.4.2

Create Ad Request

Create a GoogleIMAAdRequest ad request with ad tag url. The following snippet shows ad request creation with sample ad url end point.​

let adTagUrl =
  "https://pubads.g.doubleclick.net/gampad/ads?sz=640x480&" +
  "iu=/124319096/external/ad_rule_samples&ciu_szs=300x250" +
  "&ad_rule=1&impl=s&gdfp_req=1&env=vp&output=vast&" +
  "cust_params=deployment%3Ddevsite%26sample_ar%3Dpremidpost&cmsid=496&" +
  "vid=short_onecue&correlator=&unviewed_position_start=1";
let adRequest = FLAdvertisingGoogleIMAFactory.adRequest(adTagUrl: adTagUrl);

Create Ad Player

Create a ad Player using main content Player and GoogleIMAAdRequest and UIViewController. Please note, the created ad player cannot be used standalone, as it just manages GoogleIMA Ad playback alone. The main content playback is not managed by this ad player.​ The viewcontroler should be the parent of playback view.

// player is the main content player
let adPlayer = FLAdvertisingGoogleIMAFactory.adPlayer(
  contentPlayer: player,
  request: adRequest,
  playerViewController: viewController,
  shouldSupportPIP: true
);

note

Pre-fetch license is required for pip support. Otherwise will endup seeing DRM failures.

Create Ad Composed Player

AdComposablePlayer manages both main content player and ad player, providing a seamless main content playback with GoogleIMA ads served as per GoogleIMA Ad response.

let adComposedPlayer = FLAdvertisingGoogleIMAFactory.adComposablePlayer(
  contentPlayer: player,
  adPlayer: adPlayer,
);

This player could be used like conventional player from FLPlayer library for playback. ​

note

GoogleIMA sdk will provide the skipAd button if the ad is skippable.

Listening to Ad Events

The client can set delegate on ad player and listen to ad events to track the state of ad playback and implement custom UIs. The AdPlayer invokes the following ad delegate methods:

/// Called on ad playback failure
func adPlayer(ad: Ad?, didFailWith error: Error)

/// Called when cue points are available
func adPlayerDidProvide(cuepoints: [Int])

/// Called on ad break start
func adPlayerDidStart(adBreak: AdBreak)

/// Called on ad start
func adPlayerDidStart(ad: Ad)

/// Called on ad playback progress change
func adPlayer(ad: Ad?, didChange progress: TimeInterval)

/// Called on ad playback buffer state change
func adPlayer(ad: Ad?, didChangeBuffer isBuffering: Bool)

/// Called on occurence of ad track event
func adPlayer(ad: Ad?, didTrack event: AdTrackingEvent)

/// Called on ad end
func adPlayerDidEnd(ad: Ad)

/// Called on ad break end
func adPlayerDidEnd(adBreak: AdBreak)

Picture in Picture

​In order to support Picture in Picture, GoogleIMA SDK uses the main content player to play ad assets. In the process of playing ads, the main content asset and ad assets are switched with the player. Whenever a fairplay protected asset is loaded with player on ad break end, a on demand request for license key is made by the player. So it is suggested to prefetch the license key to avoid player requesting on-demand license whever a ad playback ends and main content is resumed playback.

CCPA compliance

The CCPA consent string must be sent as us_privacy query param with ad request url. Please check Google IMA SDK Documentation² to read further on for CCPA compliance. ​ The below code shows an ad request url with the IAB parameter "1YNN".

let adTagUrl =
  'https://pubads.g.doubleclick.net/gampad/ads' +
  'iu=/124319096/external/single_ad_samples&output=vast&us_privacy=1YNN';
