獲取數據
當視頻準備就緒時，動態攝取通知會為您提供所有您需要知道的信息-您只需要知道要查找的內容...並定義“就緒”對系統意味著什麼。此圖總結了工作流程：
動態提取通知
動態攝取通知服務向您發送有關多種事件的通知。對於確定視頻“就緒”的時間，最有用的三個是指示已創建特定演繹形式的三個，指示已創建清單的一個，指示所有處理已完成的一個。以下是每個示例：
渲染創建通知
{
"entity": "5002412132001",
"profileRefId": "ts7",
"accountId": "57838016001",
"entityType": "ASSET",
"videoId": "5002361893001",
"status": "SUCCESS",
"version": "1",
"action": "CREATE",
"jobId": "bb316631-c58b-4bd4-a686-13c5f7a3a779"
}
在此示例中註意：
- 的
videoId值可讓您知道演繹對像是哪個視頻（如果您正在運行多個攝取作業） - 的
profileRefId值是在攝取配置文件中指定的翻譯的參考ID - 如果
status值為“ SUCCESS”，表示創建成功 - 對於像HLS或MPEG-DASH之類的分段類型，呈現形式的存在並不能使其可播放-您還需要適當的清單（請參見下一個示例）。MP4 renditons一經創建就可以播放。
清單創建的通知
{
"jobId": "31f0b112-9890-4567-adb5-0f4ed1673701",
"status": "SUCCESS",
"version": "1",
"action": "CREATE",
"entityType": "ASSET",
"entity": "5002412528001",
"videoId": "5002361895001",
"profileRefId": "HlsManifest",
"accountId": "57838016001"
}
在此示例中註意：
- 的
videoId值可讓您知道演繹對像是哪個視頻（如果您正在運行多個攝取作業） - 的
profileRefIdvalue是一個特殊的代碼，告訴您創建的資產是HLS清單（其他可能的值是HdsManifest，DashManifest和SmoothIsmManifest） - 對於HLS和HDS，將創建一個清單，因此您將看到一個通知。對於DASH和SmoothIsm，將創建兩個清單（一個清單用於舊版Media API，另一個清單用於CMS API），因此您將看到兩個此類型的通知。
- 如果
status值為“ SUCCESS”，清單創建成功 - 對於像HLS或MPEG-DASH之類的分段類型，創建再現和清單沒有明確的順序-這些再現無法創建，除非兩個都創建（或者視頻已被完全處理-參見下一個示例）。
處理完成通知
{
"entityType": "TITLE",
"status": "SUCCESS",
"accountId": "57838016001",
"entity": "5002412652001",
"action": "CREATE",
"jobId": "3e98b3a0-f624-4f2d-81c1-4e43e1d04a0f",
"version": "1",
"videoId": "5002412652001"
}
在此示例中註意：
- 的
videoId值可讓您知道演繹對像是哪個視頻（如果您正在運行多個攝取作業） - 的
profileRefId是不包含在此通知中 - 如果
status值為“ SUCCESS”，視頻已成功處理
要接收通知，您需要在其中包含“回調”字段Dynamic Ingest API請求，指向一個或多個回調地址：
{
"master": {
"url": "https://s3.amazonaws.com/bucket/mysourcevideo.mp4"
}, "profile": "high-resolution",
"callbacks": ["http://host1/path1”, “http://host2/path2”]
}
樣板儀表板
本節說明如何將通知組合在一起以為Dynamic Ingest API構建簡單的儀表板。通知處理程序解析來自Dynamic Ingest API識別處理完成的通知。然後，它將視頻通知添加到JSON文件中每個視頻的對像數組中。儀表板本身是一個HTML頁面，該頁面導入JSON文件以獲取通知數據。它使用ID向CMS API獲取視頻元數據。您可以查看儀表板這裡。
該應用程序的所有文件以及為您的帳戶進行設置的說明均在這個倉庫。
這是應用程序的高級架構：
應用程式零件
通知處理程序內置於PHP中-用於查找完整的通知，並將視頻ID添加到單獨JavaScript文件中的數組中：
<？php
// var以記錄錯誤（如果有）
$ 問題 =「無錯誤」;
// var存儲當前視頻索引
$ videoIndex = -1;
//獲取輸入數據
嘗試{
$ JSON = 文件的內容（'PHP：//輸入'）;
$ 解碼 = 解碼（$ JSON，真）;
} catch（Exception $ e）{
$ 問題 = $ 電子-> 獲取消息（）;
迴聲$問題;
}
//獲取數據文件內容並解析
嘗試{
$ notificationData = file_get_contents（'di.json'）;
$ notificationDataDecoded = json_decode（$ notificationData，true）;
} catch（Exception $ e）{
$ 問題 = $ 電子-> 獲取消息（）;
迴聲$問題;
}
如果（isset（$ decoded [“ entityType”]））{
$ 實體類型 = $ 解碼 ["實體類型"];
//如果實體類型為ASSET或TITLE，則將其添加到通知數據數組
如果（$ entityType ==“ ASSET” || $ entityType ==“ TITLE”）{
array_push（$ notificationDataDecoded，$ decoded）;
}
//現在，我們將用現有的內容替換di.json的內容
file_put_contents（'di.json'，json_encode（$ notificationDataDecoded））;
}
回顯“ Dynamic Ingest回調應用程序正在運行”；
var_dump（$ notificationData）;

JSON檔案：
JSON文件最初是一個空數組（[]）-數據由通知處理程序添加。
儀表板
信息中心包含HTML和JavaScript，可從中獲取通知數據和其他視頻數據CMS API並將結果寫到表中：
