Framework Cast menyediakan API antrean yang mendukung pembuatan daftar
item konten, seperti streaming video atau audio, untuk diputar secara berurutan di Web
Penerima. Antrean item konten dapat diedit, diurutkan ulang, diperbarui, dan sebagainya
dan seterusnya.
Web Receiver SDK mengelola antrean dan merespons operasi pada
dalam antrean selama antrean memiliki setidaknya satu item yang sedang aktif (sedang diputar atau
dijeda). Pengirim dapat bergabung dalam sesi dan menambahkan item ke antrean. Penerima
mempertahankan sesi untuk item antrean hingga item terakhir menyelesaikan pemutaran atau
pengirim menghentikan pemutaran dan mengakhiri sesi, atau hingga pengirim
memuat antrean baru di penerima. Penerima tidak mempertahankan
informasi tentang antrean yang
dihentikan secara {i>default<i}. Setelah item terakhir dalam antrean
selesai, sesi media berakhir
dan antrean menghilang.
Membuat dan memuat item antrean media
Di iOS, item antrean media ditampilkan dalam framework Cast sebagai
Instance GCKMediaQueueItem.
Saat membuat item antrean media dengan konten adaptif, Anda dapat menyetel
waktu pramuat sehingga pemutar dapat mulai
menyangga item antrean media sebelum
item di depannya dalam antrean selesai diputar. Lihat selengkapnya tentang pramuat di
tindakan
Panduan pramuat Penerima Web.
Menyetel putar otomatis item
ke true (benar) memungkinkan Penerima Web memutarnya secara otomatis. Misalnya,
Anda dapat menggunakan pola builder untuk membuat item antrean media seperti berikut:
Muat array item antrean media dalam antrean dengan menggunakan
Metode queueLoadItems dari
GCKRemoteMediaClient
.
Menerima pembaruan status antrean media
Saat Penerima Web memuat item antrean media, penerima web menetapkan ID unik ke
item yang bertahan selama durasi sesi (dan masa aktif antrean).
Anda dapat mempelajari status antrean yang menunjukkan item mana yang saat ini dimuat
(mungkin tidak sedang diputar), memuat, atau dipramuat. Anda juga bisa mendapatkan pesanan
daftar semua item dalam antrean. Tujuan
GCKMediaStatus
memberikan informasi status berikut:
preloadedItemID
properti - ID item yang saat ini dipramuat, jika ada.
currentItemID
properti - ID item antrean saat ini, jika ada.
queueItemCount
- Menampilkan jumlah item dalam antrean pemutaran.
queueItemAtIndex
- Menampilkan item di indeks yang ditetapkan dalam antrean pemutaran.
Gunakan anggota ini bersama dengan anggota status media lainnya untuk memberi tahu
tentang status antrean dan item dalam antrean. Selain
pembaruan status media dari Penerima Web, Anda dapat mendengarkan perubahan pada
antrean dengan mengimplementasikan -[remoteMediaClientDidUpdateQueue:]GCKRemoteMediaClientListener.
Edit antrean
Untuk bekerja dengan item dalam antrean, gunakan metode antrean
GCKRemoteMediaClient
Anda memiliki beberapa API. Ini memungkinkan Anda memuat array item ke dalam antrean baru,
memasukkan item ke antrean yang ada, memperbarui properti item
antrian, membuat item melompat maju atau mundur dalam antrian, mengatur properti
antrean itu sendiri (misalnya, ubah repeatMode yang memilih antrean
item), hapus item dari antrean, dan susun ulang item dalam antrean.

Senders can create, edit, reorder, and update queues. The Web Receiver manages the queue as long as it has an active item, maintaining session until the last item finishes or the session is terminated. In iOS, `GCKMediaQueueItem` represents queue items, with options for autoplay and preloading. `GCKMediaStatus` provides information about the loaded, loading, or preloaded item and the queue status. `GCKRemoteMediaClient` allows to load, insert, update, remove, and reorder items.\n"],null,["# Queueing\n\nThe Cast framework provides queueing APIs that support the creation of lists of\ncontent items, such as video or audio streams, to play sequentially on the Web\nReceiver. The queue of content items may be edited, reordered, updated, and so\nforth.\n| **Note:** Review the [Google Cast Autoplay](/cast/docs/design_checklist/cast-autoplay) for best practices when designing an autoplay or queueing experience for Cast.\n\nThe Web Receiver SDK maintains the queue and responds to operations on the\nqueue as long as the queue has at least one item currently active (playing or\npaused). Senders can join the session and add items to the queue. The receiver\nmaintains a session for queue items until the last item completes playback or\nthe sender stops the playback and terminates the session, or until a sender\nloads a new queue on the receiver. The receiver does not maintain any\ninformation about terminated queues by default. Once the last item in the queue\nfinishes, the media session ends and the queue vanishes.\n| **Note:** The [Styled](/cast/docs/styled_receiver) and [Default Media](/cast/docs/web_receiver#default_media_web_receiver) Receivers only support a queue of audio or video streams. To use a queue of images, you must develop a [Custom Receiver](/cast/docs/web_receiver/basic).\n\nCreate and load media queue items\n---------------------------------\n\nIn iOS, a media queue item is represented in the Cast framework as a\n[`GCKMediaQueueItem` instance](/cast/docs/reference/ios/interface_g_c_k_media_queue_item).\nWhen you create a media queue item with adaptive content, you can set the\npreload time so that the player can begin buffering the media queue item before\nthe item ahead of it in the queue finishes playing. See more about preloading in\nthe\n[Web Receiver preloading guide](/cast/docs/web_receiver/core_features#content_preload).\n\nSetting the item's autoplay\nattribute to true allows the Web Receiver to play it automatically. For example,\nyou can use a builder pattern to create your media queue item as follows:\nSwift \n\n```swift\nlet builder = GCKMediaQueueItemBuilder.init()\nbuilder.mediaInformation = mediaInformation\nbuilder.autoplay = true\nbuilder.preloadTime = 8.0\nlet newItem = builder.build()\n```\nObjective-C \n\n```objective-c\nGCKMediaQueueItemBuilder *builder = [[GCKMediaQueueItemBuilder alloc] init];\nbuilder.mediaInformation = self.mediaInformation;\nbuilder.autoplay = YES;\nbuilder.preloadTime = 8.0;\nGCKMediaQueueItem *newItem = [builder build];\n```\n\nLoad an array of media queue items in the queue by using the appropriate\n`queueLoadItems` method of the\n[`GCKRemoteMediaClient`](/cast/docs/reference/ios/interface_g_c_k_remote_media_client)\nclass.\n\nReceive media queue status update\n---------------------------------\n\nWhen the Web Receiver loads a media queue item, it assigns a unique ID to the\nitem that persists for the duration of the session (and the life of the queue).\nYou can learn the status of the queue indicating which item is currently loaded\n(it might not be playing), loading, or preloaded. You can also get an ordered\nlist of all the items in the queue. The\n[`GCKMediaStatus`](/cast/docs/reference/ios/interface_g_c_k_media_status)\nclass provides this status information:\n\n- [`preloadedItemID`](/cast/docs/reference/ios/interface_g_c_k_media_status#aca544cb983806b859c0d62c6e1438150) property - The ID of the item that is currently preloaded, if any.\n- [`loadingItemID`](/cast/docs/reference/ios/interface_g_c_k_media_status#a0676da67792f35cbea8de2bc9015b05d) property - The ID of the item that is currently loading,\n- [`currentItemID`](/cast/docs/reference/ios/interface_g_c_k_media_status#a1818b62cd378f6648d06042dce494c58) property - The ID of the current queue item, if any.\n- [`queueItemCount`](/cast/docs/reference/ios/interface_g_c_k_media_status#a2ba0ff0a3da66b18520c2858388bc58d) method - Returns the number of items in the playback queue.\n- [`queueItemAtIndex`](/cast/docs/reference/ios/interface_g_c_k_media_status#ad1417e02dca50f0cfd5841c614bd41fa) method - Returns the item at the specified index in the playback queue.\n\nUse these members together with the other media status members to inform your\napp about the status of the queue and the items in the queue. In addition to\nmedia status updates from the Web Receiver, you can listen for changes to the\nqueue by implementing `-[remoteMediaClientDidUpdateQueue:]` of the\n[`GCKRemoteMediaClientListener`](/cast/docs/reference/ios/protocol_g_c_k_remote_media_client_listener-p).\n| **Note:** To provide the best user experience, the sender app must show the next autoplay item in the queue in the sender UI.\n\nEdit the queue\n--------------\n\nTo work with the items in the queue, use the queue methods of\n[`GCKRemoteMediaClient`](/cast/docs/reference/ios/interface_g_c_k_remote_media_client).\nyou have several APIs. These let you load an array of items into a new queue,\ninsert items into an existing queue, update the properties of items in the\nqueue, make an item jump forward or backward in the queue, set the properties of\nthe queue itself (for example, change the `repeatMode` that selects the next\nitem), remove items from the queue, and reorder the items in the queue."]]
