Memuat iklan pre-roll untuk live stream
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
IMA SDK dapat digunakan untuk memonetisasi live stream serta video on demand.
Untuk live stream, Anda harus membuat permintaan iklan baru untuk setiap jeda iklan.
Sesuaikan permintaan ini untuk memastikan semua penonton Anda tidak mengajukan permintaan
iklan pada saat yang sama dan
memperlambat server iklan.
Untuk membantu melakukan tugas ini, IMA SDK memiliki AdsRequest.liveStreamPrefetchSeconds
saat ini. Properti ini menentukan jumlah detik maksimum SDK
harus menunggu sebelum menghubungi server iklan setelah Anda memanggil
AdsLoader.requestAds(). Waktu permintaan sebenarnya akan diacak. Sebagai
misalnya, jika Anda menetapkan AdsRequest.liveStreamPrefetchSeconds ke 30, SDK
menunggu 0 hingga 30 detik setelah Anda memanggil AdsLoader.requestAds() untuk
membuat permintaan ke server.
Praktik pengambilan awal live stream
Sebaiknya lakukan pengambilan data jeda iklan berikutnya segera setelah jeda iklan selesai.
Hal ini memastikan durasi waktu maksimum tersedia untuk periode pra-pengambilan Anda.
Misalkan Anda memiliki jeda 5 menit di antara jeda iklan. Saat jeda iklan selesai,
Anda dapat meminta jeda iklan berikutnya dengan periode pra-pengambilan selama 290 detik
(5 menit dikurangi 10 detik, untuk memastikan permintaan dikirim pada akhir
jendela pra-pengambilan 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 }"]]
