加速轉碼任務設定範例 JSON
下列範例JSON任務會將MP4檔案轉換為另一個以 H.265 編碼的 720p MP4 檔案。若要使用這個範例，請使用您的值取代設定。您至少必須提供下列設定值：
-
Role：這是 AWS Identity and Access Management 您設定的 （IAM） 角色，用於授予 AWS Elemental 存取輸入和輸出 Amazon S3 儲存貯體的 MediaConvert 許可，以及代表您存取 Amazon API Gateway。如需有關設定此角色的資訊，請參閱 AWS Elemental MediaConvert 使用者指南 中的設定IAM許可。 -
Destination：您要 MediaConvert 存放輸出檔案的 Amazon S3 儲存貯體。務必包含節尾斜線，如範例所示。 -
InputClippings：指定StartTimecode和EndTimecode的值集，以定義您要轉碼的剪輯。或者，您可以完全移除InputClippings以進行整個資產的轉碼。 -
FileInput：為您的輸入檔指定檔案名稱和位置。您的檔案輸入可以是 Amazon S3 物件或 HTTP URL。只有單一輸入的任務可支援加速轉碼；您無法進行輸入拼接。
