2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

Parameter NameRequiredTypeDescription
ActionYesStringCommon Params. The value used for this API: ProcessMedia.
VersionYesStringCommon Params. The value used for this API: 2019-06-12.
RegionNoStringCommon Params. This parameter is not required for this API.
InputInfoYesMediaInputInfoThe information of the file to process.
OutputStorageNoTaskOutputStorageThe storage location of the media processing output file. If this parameter is left empty, the storage location in InputInfo will be inherited.
OutputDirNoStringThe directory to save the media processing output file, which must start and end with /, such as /movie/201907/.
If you do not specify this parameter, the file will be saved to the directory specified in InputInfo.
ScheduleIdNoIntegerThe scheme ID.
Note 1: About OutputStorage and OutputDir
  • If an output storage and directory are specified for a subtask of the scheme, those output settings will be applied.
  • If an output storage and directory are not specified for the subtasks of a scheme, the output parameters passed in the ProcessMedia API will be applied.

  • Note 2: If TaskNotifyConfig is specified, the specified settings will be used instead of the default callback settings of the scheme.

    Note 3: The trigger configured for a scheme is for automatically starting a scheme. It stops working when you manually call this API to start a scheme.
    MediaProcessTaskNoMediaProcessTaskInputThe media processing parameters to use.
    AiContentReviewTaskNoAiContentReviewTaskInputType parameter of a video content audit task.
    AiAnalysisTaskNoAiAnalysisTaskInputVideo content analysis task parameter.
    AiRecognitionTaskNoAiRecognitionTaskInputType parameter of a video content recognition task.
    AiQualityControlTaskNoAiQualityControlTaskInputThe parameters of a quality control task.
    TaskNotifyConfigNoTaskNotifyConfigEvent notification information of a task. If this parameter is left empty, no event notifications will be obtained.
    TasksPriorityNoIntegerTask flow priority. The higher the value, the higher the priority. Value range: [-10, 10]. If this parameter is left empty, 0 will be used.
    SessionIdNoStringThe ID used for deduplication. If there was a request with the same ID in the last three days, the current request will return an error. The ID can contain up to 50 characters. If this parameter is left empty or an empty string is entered, no deduplication will be performed.
    SessionContextNoStringThe source context which is used to pass through the user request information. The task flow status change callback will return the value of this field. It can contain up to 1,000 characters.
    TaskTypeNoStringThe task type.
  • Online (default): A task that is executed immediately.
  • Offline: A task that is executed when the system is idle (within three days by default).
  • 3. Output Parameters

    Parameter NameTypeDescription
    TaskIdStringTask ID.
    RequestIdStringThe unique request ID, which is returned for each request. RequestId is required for locating a problem.
