Quảng cáo gốc cung cấp quyền truy cập vào một lớp GADMediaContent được dùng để lấy thông tin về nội dung nghe nhìn. Nội dung này có thể là video hoặc hình ảnh. Nội dung này cũng được dùng để kiểm soát hoạt động phát quảng cáo dạng video và nghe các sự kiện phát. Bạn có thể truy cập vào đối tượng nội dung nghe nhìn thông qua thuộc tính .mediaContent trên quảng cáo.
Đối tượng GADMediaContent chứa các thông tin, chẳng hạn như tỷ lệ khung hình và thời lượng của video. Đoạn mã
dưới đây cho biết cách lấy tỷ lệ khung hình và thời lượng của quảng cáo gốc.
Để xử lý các sự kiện video cụ thể, bạn cần viết một lớp triển khai giao thức GADVideoControllerDelegate. Các phương thức của giao thức đều là không bắt buộc.
Ví dụ sau đây minh hoạ cách triển khai giao thức uỷ quyền:

This method allows you to define actions for when a video starts, pauses, ends, or changes its mute state.\n"],null,["Select platform: [Android](/ad-manager/mobile-ads-sdk/android/native/video-ads \"View this page for the Android platform docs.\") [iOS](/ad-manager/mobile-ads-sdk/ios/native/video-ads \"View this page for the iOS platform docs.\")\n\n\u003cbr /\u003e\n\nPrerequisites\n\n- Integrate the [Native ad format](/ad-manager/mobile-ads-sdk/ios/native).\n\nGADMediaContent\n\nNative ads provide access to a `GADMediaContent` class that is used to get\ninformation about media content which could be a video or an image. It is also\nused to control the video ad playback listen for playback events. You can access\nthe media content object via the `.mediaContent` property on the ad.\n\nThe\n[`GADMediaContent`](/ad-manager/mobile-ads-sdk/ios/api/reference/Classes/GADMediaContent)\nobject contains information such as the aspect ratio and duration of video. The\nsnippet below shows how to get the aspect ratio and duration of a native ad. \n\nSwift \n\n```swift\nif myNativeAd.mediaContent.hasVideoContent {\n let mediaAspectRatio = CGFloat(myNativeAd.mediaContent.aspectRatio)\n let duration = myNativeAd.mediaContent.duration\n}\n```\n\nObjective-C \n\n```objective-c\nif(myNativeAd.mediaContent.hasVideoContent) {\n CGFloat mediaAspectRatio = myNativeAd.mediaContent.aspectRatio;\n NSTimeInterval duration = myNativeAd.mediaContent.duration;\n}\n```\n\nGADVideoController\n\nThe `GADMediaContent` object has a reference to a\n[`GADVideoController`](/ad-manager/mobile-ads-sdk/ios/api/reference/Classes/GADVideoController)\nobject. The `GADVideoController` object allows publishers to respond to video\nevents.\n\nAds served through [line items](//support.google.com/admanager/answer/82236) can\nalso be controlled with the `GADVideoController`.\n\nThis `GADVideoController` object can be obtained by calling\n[`GADMediaContent.videoController`](/ad-manager/mobile-ads-sdk/ios/api/reference/Classes/GADMediaContent#videocontroller).\n\nCallbacks for video events\n\nTo handle specific video events you need to write a class that implements the\n[`GADVideoControllerDelegate`](/ad-manager/mobile-ads-sdk/ios/api/reference/Protocols/GADVideoControllerDelegate)\nprotocol. The methods of the protocol are all optional.\n\nThe following example shows how to implement the delegate protocol: \n\nSwift \n\n```swift\nclass ViewController: NativeAdLoaderDelegate, VideoControllerDelegate {\n private var adLoader: AdLoader?\n\n func viewDidLoad() {\n super.viewDidLoad()\n\n let videoOptions = VideoOptions()\n videoOptions.customControlsRequested = true\n adLoader = AdLoader(\n adUnitID: \"ca-app-pub-3940256099942544/3986624511\",\n rootViewController: self,\n adTypes: [.native],\n options: [videoOptions])\n adLoader?.delegate = self\n adLoader?.load(AdManagerRequest())\n\n }\n\n func adLoader(\n _ adLoader: AdLoader?,\n didReceive nativeAd: NativeAd?\n ) {\n // Set the videoController's delegate to be notified of video events.\n nativeAd?.mediaContent.videoController.delegate = self\n }\n\n // VideoControllerDelegate methods\n func videoControllerDidPlayVideo(_ videoController: VideoController) {\n // Implement this method to receive a notification when the video controller\n // begins playing the ad.\n }\n\n func videoControllerDidPauseVideo(_ videoController: VideoController) {\n // Implement this method to receive a notification when the video controller\n // pauses the ad.\n }\n\n func videoControllerDidEndVideoPlayback(_ videoController: VideoController) {\n // Implement this method to receive a notification when the video controller\n // stops playing the ad.\n }\n\n func videoControllerDidMuteVideo(_ videoController: VideoController) {\n // Implement this method to receive a notification when the video controller\n // mutes the ad.\n }\n\n func videoControllerDidUnmuteVideo(_ videoController: VideoController) {\n // Implement this method to receive a notification when the video controller\n // unmutes the ad.\n }\n}\n```\n\nObjective-C \n\n```objective-c\n@interface ViewController () \u003cGADNativeAdLoaderDelegate,\n GADVideoControllerDelegate\u003e\n@property(nonatomic, strong) GADAdLoader *adLoader;\n\n@end\n\n@implementation ViewController\n- (void)viewDidLoad {\n [super viewDidLoad];\n\n GADVideoOptions *videoOptions = [[GADVideoOptions alloc] init];\n videoOptions.customControlsRequested = YES;\n self.adLoader =\n [[GADAdLoader alloc] initWithAdUnitID:@\"ca-app-pub-3940256099942544/3986624511\"\n rootViewController:self\n adTypes:@[ GADAdLoaderAdTypeNative ]\n options:@[ videoOptions ]];\n self.adLoader.delegate = self;\n [self.adLoader loadRequest:[GAMRequest request]];\n\n}\n\n- (void)adLoader:(GADAdLoader *)adLoader\n didReceiveNativeAd:(GADNativeAd *)nativeAd {\n // Set the videoController's delegate to be notified of video events.\n nativeAd.mediaContent.videoController.delegate = self;\n}\n\n// GADVideoControllerDelegate methods\n- (void)videoControllerDidPlayVideo:(nonnull GADVideoController *)videoController {\n // Implement this method to receive a notification when the video controller\n // begins playing the ad.\n}\n\n- (void)videoControllerDidPauseVideo:(nonnull GADVideoController *)videoController {\n // Implement this method to receive a notification when the video controller\n // pauses the ad.\n}\n\n- (void)videoControllerDidEndVideoPlayback:(nonnull GADVideoController *)videoController {\n // Implement this method to receive a notification when the video controller\n // stops playing the ad.\n}\n\n- (void)videoControllerDidMuteVideo:(nonnull GADVideoController *)videoController {\n // Implement this method to receive a notification when the video controller\n // mutes the ad.\n}\n\n- (void)videoControllerDidUnmuteVideo:(nonnull GADVideoController *)videoController {\n // Implement this method to receive a notification when the video controller\n // unmutes the ad.\n}\n\n@end\n```\n\nRead the [Native ads policies and\nguidelines](//support.google.com/admob/answer/6329638) for more guidance on how\nto render your native ads."]]
