AWS Elemental MediaConvert 加速转码 JSON 任务示例

以下示例 JSON 作业将 MP4 文件转换为使用 H.265 进行 720p 编码的其他 MP4 文件。要使用此示例，请使用您的值替换设置。必须至少提供以下设置的值：

  • Role：这是您设置的 Amazon Identity and Access Management (IAM) 角色，旨在授予 AWS Elemental MediaConvert 访问您的输入和输出 Amazon S3 存储桶以及代表您访问 Amazon API Gateway 的 MediaConvert 权限。有关设置此角色的信息，请参阅 AWS Elemental MediaConvert 用户指南中的设置 IAM 权限。

  • Destination：您要 MediaConvert 存储输出文件的 Amazon S3 存储桶。请务必包含尾部反斜杠，如示例所示。

  • InputClippings：通过为 StartTimecode 和 EndTimecode 指定一组值，定义您希望转码的剪辑。或者，您也可以删除 InputClippings 以完全转码整个资产。

  • FileInput：为您的输入文件指定文件名和位置。您的文件输入可以是 Amazon S3 对象或 HTTP URL。

    加速转码支持只有一个输入的作业，您不能进行输入拼接。
