回應內文

當您建立任務時，Elastic Transcoder 會傳回您在請求中指定的值。如需詳細資訊，請參閱您在建立彈性轉碼器任務時指定的設定。

此外，Elastic Transcoder 會傳回下列值。

（自動） ID

Elastic Transcoder 指派給任務的識別符。您可以使用此值來取得任務的設定或刪除任務。

（自動）輸出：Id

從 1 開始的循序計數器，可識別目前任務中輸出之間的輸出。在Output語法中，此值一律為 1。

（自動）輸出：持續時間

輸出檔案的持續時間，以秒為單位，四捨五入。

（自動）輸出：寬度

輸出檔案的寬度，以像素為單位。

（自動）輸出：高度

輸出檔案的高度，以像素為單位。

（自動）輸出：狀態

任務中一個輸出的狀態。如果您只為任務指定一個輸出， Outputs:Status 一律與相同Job:Status。如果您指定多個輸出：

Job:Status Outputs:Status 對於所有輸出，和是Submitted直到 Elastic Transcoder 開始處理第一個輸出為止。
當 Elastic Transcoder 開始處理第一個輸出時，Outputs:Status該輸出和Job:Status兩者都會變更為 Progressing。對於每個輸出，的值會Outputs:Status保留Submitted到 Elastic Transcoder 開始處理輸出為止。
Job:Status 會保留，Progressing直到所有輸出都達到終端機狀態，Complete或 Error為止。
當所有輸出都達到終端機狀態時，只有在所有輸出Outputs:Status為時， Complete才會Job:Status變更為 Complete。如果一或多個輸出Outputs:Status是 Error，則的終端機狀態Job:Status也是 Error。

的值Status是下列其中一項：Submitted、Progressing、Canceled、 Complete或 Error。

（自動）輸出：StatusDetail

進一步說明的資訊Outputs:Status。

（自動）輸出：AppliedColorSpaceConversion

如果 Elastic Transcoder 搭配使用預設集ColorSpaceConversionMode來轉碼輸出檔案， AppliedColorSpaceConversion 參數會顯示使用的轉換。如果預設中ColorSpaceConversionMode未定義任何，則此參數不會包含在任務回應中。

（自動）狀態

如果您為任務指定多個輸出，則為整個任務的狀態。當 Elastic Transcoder 開始處理任務時，的值Job:Status會變更為 Progressing，且直到 Elastic Transcoder 處理完所有輸出後才會變更。處理完成時，會Job:Status變更為，Complete如果任何輸出失敗，則會變更為 Error。

如果您只為任務指定一個輸出，Job:Status則與相同Outputs:Status。

的值Job:Status是下列其中一項：Submitted、Progressing、Canceled、 Complete或 Error。
