	object	The response parameters.
NonExistRunIds	object
RunId	array	The IDs of the execution instances that do not exist.
	string	The IDs of the execution instances that do not exist. null is returned if all specified execution instances exist.	null
MediaWorkflowExecutionList	object
MediaWorkflowExecution	array<object>	The details of the media workflows.
	array<object>	The information about the media workflow.
CreationTime	string	The time when the media workflow was created.	016-04-01T06:53:43Z
MediaWorkflowId	string	The ID of the media workflow.	93ab850b4f6f44eab54b6e91****81d4
State	string	The status of the media workflow. Valid values: Running: The media workflow is running. Completed: The media workflow is complete. Catatan Completed only indicates that the media workflow is complete. View the status of each method in the workflow, such as the transcode and snapshot methods, to check whether the method is called. Fail: The media workflow fails.	Completed
ActivityList	object
Activity	array<object>	The methods that are called in the media workflow.
	array<object>	The details of the method.
EndTime	string	The time when the method ends.	2016-04-01T06:53:44Z
Type	string	The methods that are supported in the media workflow. Valid values: Start, Snapshot, Transcode, Analysis, and Report. For more information, see Methods supported for media workflows.	Start
StartTime	string	The time when the method is called.	2016-04-01T06:53:44Z
State	string	The status of the workflow method. Valid values: Running: The method is being called. Success: The method is called. Fail: The method failed to be called. Skipped: The method is skipped. Catatan For example, after the analysis is complete, the transcode method is called and high-definition and standard-definition transcoding jobs are created. The system determines whether to run the jobs based on the analysis result. If the resolution of the input video is low, the high-definition transcoding job may be skipped.	Running
JobId	string	The IDs of the jobs that are generated when the methods are called, such as the job IDs for the analysis, transcode, and snapshot methods.	2376030d9d0849399cd20e20f4f3****
Code	string	The error code. This parameter is returned only if Fail is returned for the State parameter. This parameter is not returned if the method status is Success.	InvalidParameter.ResourceContentBad
Message	string	The error message. This parameter is returned only if Fail is returned for the State parameter. This parameter is not returned if the method status is Success.	The resource operated InputFile is bad
Name	string	The name of the method. Catatan The name of each method in a media workflow is unique.	Start
MNSMessageResult	object	The message sent by Message Service (MNS) to notify the user of the job result.
MessageId	string	The ID of the message that indicates the MNS message is sent. This parameter is not returned if the MNS message fails to be sent.	4f3bc83233de4e2f81c7dade443e****
