Memuat iklan pre-roll untuk live stream
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Google Interactive Media Ads (IMA) SDK untuk iOS.
IMA SDK dapat digunakan untuk memonetisasi live stream dan video on demand.
Untuk live stream, Anda harus membuat permintaan iklan baru untuk setiap jeda iklan.
Lakukan permintaan ini secara bertahap untuk memastikan semua penonton Anda tidak meminta iklan secara bersamaan dan memperlambat server iklan.
Untuk membantu hal ini, IMA SDK memiliki properti AdsRequest.liveStreamPrefetchSeconds. Properti ini menentukan jumlah detik maksimum yang harus ditunggu SDK
sebelum menghubungi server iklan setelah Anda memanggil
AdsLoader.requestAds(). Waktu permintaan sebenarnya akan diacak. Misalnya, jika Anda menetapkan AdsRequest.liveStreamPrefetchSeconds ke 30, SDK akan menunggu 0 hingga 30 detik setelah Anda memanggil AdsLoader.requestAds() untuk benar-benar membuat permintaan ke server.
Prefetch live stream dalam praktiknya
Sebaiknya lakukan pengambilan data iklan berikutnya segera setelah jeda iklan selesai.
Hal ini memastikan durasi maksimum tersedia untuk jendela pengambilan data sebelumnya.
Misalnya, Anda memiliki 5 menit di antara jeda iklan. Setelah jeda iklan selesai,
Anda dapat meminta jeda iklan berikutnya dengan jendela pengambilan data 290 detik
(5 menit dikurangi 10 detik, untuk memastikan permintaan yang dikirim di akhir
jendela pengambilan data memiliki cukup waktu untuk diselesaikan):

This property specifies the maximum number of seconds the SDK\nshould wait before reaching out to the ad server after you call\n`AdsLoader.requestAds()`. The actual request time will be randomized. For\nexample, if you set `AdsRequest.liveStreamPrefetchSeconds` to 30, the SDK\nwaits 0 to 30 seconds after you call `AdsLoader.requestAds()` to actually\nmake the request to the server.\n\nLive stream pre-fetch in practice\n---------------------------------\n\nWe recommend pre-fetching your next ad break as soon as an ad break completes.\nThis ensures the maximum length of time is available for your pre-fetch window.\nSuppose you have 5 minutes between ad breaks. When an ad break completes,\nyou can request your next ad break with a pre-fetch window of 290 seconds\n(5 minutes minus 10 seconds, to make sure the requests sent at the end of\nthe pre-fetch window have enough time to resolve): \n\n### Objective-C\n\n\n - (void)adsManager:(IMAAdsManager *)adsManager didReceiveAdEvent:(IMAAdEvent *)event {\n\n ...\n\n switch (event.type) {\n\n ...\n\n case kIMAAdEvent_ALL_ADS_COMPLETED:\n\n IMAAdsRequest *request = [[IMAAdsRequest alloc]\n initWithAdTagUrl: self.adTagUrl\n adDisplayContainer: self.adDisplayContainer\n avPlayerVideoDisplay: self.avPlayerVideoDisplay\n pictureInPictureProxy: self.pictureInPictureProxy\n userContext: nil];\n\n // set a delay between the end of the last ad\n // in the last request, and the first ad from\n // the new request\n Float64 adGap = 30;\n // make sure the request occurs at least five\n // seconds before starting the new set of ads\n request.liveStreamPrefetchSeconds = adGap - 5;\n [self.adsLoader requestAdsWithRequest:request];\n // start new ads after adGap seconds have elapsed\n dispatch_after(dispatch_time(DISPATCH_TIME_NOW, adGap * NSEC_PER_SEC), dispatch_get_main_queue(), ^{\n [adsManager start];\n });\n\n break;\n\n ...\n\n }\n\n ...\n\n }\n\n### Swift\n\n func adsManager(_ adsManager: IMAAdsManager!, didReceive event: IMAAdEvent!) {\n switch event.type {\n\n ...\n\n case IMAAdEventType.ALL_ADS_COMPLETED:\n\n let request = IMAAdsRequest(\n adTagUrl: AdTagUrl,\n adDisplayContainer: adDisplayContainer,\n contentPlayhead: contentPlayhead,\n userContext: nil)\n\n // set a delay between the end of the last ad\n // in the last request, and the first ad from\n // the new request\n let adGap = 30\n // make sure the request occurs at least five\n // seconds before starting the new set of ads\n request.liveStreamPrefetchSeconds = adGap - 5\n adsLoader.requestAds(with: request)\n // start new ads after adGap seconds have elapsed\n DispatchQueue.main.asyncAfter(deadline: .now() + adGap) {\n adsManager.start()\n }\n\n break\n\n ...\n }\n }"]]
