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)Inputs: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)Inputs:FrameRate
检测到的输入文件帧率(以每秒帧数为单位)。
- (自动)Inputs:FileSize
检测到的输入文件大小(以字节为单位)。
- (自动)Inputs: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)Outputs: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)Outputs:FrameRate
-
输出文件的帧率(以每秒帧数为单位)。
- (自动)Outputs: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)Outputs:StatusDetail
-
进一步解释
Outputs:Status
的信息。 - (自动) Outputs: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)Timing:SubmitTimeMillis
-
任务提交给 Elastic Transcoder 的时间(以纪元毫秒为单位)。
- (自动)Timing:StartTimeMillis
-
任务开始转码的时间(以纪元毫秒为单位)。
- (自动)Timing: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。
