响应标头

此操作仅使用大多数响应通用的响应标头。有关通用响应标头的信息，请参阅 HTTP 响应。

响应正文

对于满足搜索条件的每个任务，响应正文中均包含在创建任务时指定的值。有关任务值的更多信息，请参阅您在创建 Elastic Transcoder 任务时指定的设置。

此外，Elastic Transcoder 将返回以下值。

（自动）Id

Elastic Transcoder 为任务分配的标识符。您使用该值获取任务的设置或删除任务。

（自动）输入：DetectedProperties

检测到的输入文件的属性。Elastic Transcoder 从输入文件识别这些值。

（自动）Inputs:Width

检测到的输入文件宽度（以像素为单位）。

（自动）Inputs:Height

检测到的输入文件高度（以像素为单位）。

（自动）输入：FrameRate

检测到的输入文件帧率（以每秒帧数为单位）。

（自动）输入：FileSize

检测到的输入文件大小（以字节为单位）。

（自动）输入：DurationMillis

检测到的输入文件持续时间（以毫秒为单位）。

（自动）Outputs:Id

以 1 开头的顺序计数器，用于在当前任务的输出中标识输出。在 Output 语法中，此值始终为 1。

（自动）Outputs:Duration

输出文件的持续时间（以秒为单位），向上取整。

（自动）输出：DurationMillis

输出文件的持续时间（以毫秒为单位）。

（自动）Outputs:Width

输出文件的宽度（以像素为单位）。

（自动）Outputs:Height

输出文件的高度（以像素为单位）。

（自动）输出：FrameRate

输出文件的帧率（以每秒帧数为单位）。

（自动）输出：FileSize

输出文件的文件大小（以字节为单位）。

（自动）Outputs:Status

任务中一个输出的状态。如果您只为该任务指定了一个输出，则 Outputs:Status 始终与 Job:Status 相同。如果您指定了多个输出：

所有输出的 Job:Status 和 Outputs:Status 都是 Submitted，直到 Elastic Transcoder 开始处理第一个输出。
当 Elastic Transcoder 开始处理第一个输出时，该输出的 Outputs:Status 和 Job:Status 都更改为 Progressing。对于每个输出，Outputs:Status 的值将保持为 Submitted，直到 Elastic Transcoder 开始处理输出。
Job:Status 保持为 Progressing，直到所有输出都达到终端状态，Complete 或者 Error。
当所有输出都达到终端状态时，仅当所有输出的 Outputs:Status 都是 Complete 时，Job:Status 才会更改为 Complete。如果一个或多个输出的 Outputs:Status 是 Error，则 Job:Status 的终端状态也是 Error。

Status 的值为以下值之一：Submitted、Progressing、Complete、Canceled 或 Error。

（自动）输出：StatusDetail

进一步解释 Outputs:Status 的信息。

（自动）输出：AppliedColorSpaceConversion

如果 Elastic Transcoder 使用带有 ColorSpaceConversionMode 的预设对输出文件进行转码，则 AppliedColorSpaceConversion 参数会显示所使用的转换。如果在预设中未定义 ColorSpaceConversionMode，则此参数将不会包含在任务响应中。

（自动）Status

如果您为任务指定了多个输出，则为整个任务的状态。当 Elastic Transcoder 开始处理任务时，Job:Status 的值会更改为 Progressing，并且在 Elastic Transcoder 完成对所有输出的处理之前不会发生变化。处理完成后，Job:Status 更改为 Complete，如果有任何输出失败，则更改为 Error。

如果您只为该任务指定了一个输出，则 Job:Status 与 Outputs:Status 相同。

Job:Status 的值为以下值之一：Submitted、Progressing、Complete、Canceled 或 Error。

（自动）Timing

有关任务时间的详细信息。

（自动）定时：SubmitTimeMillis

任务提交给 Elastic Transcoder 的时间（以纪元毫秒为单位）。

（自动）定时：StartTimeMillis

任务开始转码的时间（以纪元毫秒为单位）。

（自动）定时：FinishTimeMillis

任务完成转码的时间（以纪元毫秒为单位）。

要了解有关纪元时间的更多信息，请访问 Wikipedia 上的纪元计算页面。
