Create Job

Description

To create a job, send a POST request to the /2012-09-25/jobs resource. Jobs start as soon as you create them.

Note

You can configure Elastic Transcoder to notify you when the status of a job changes, including when Elastic Transcoder starts and finishes processing a job, and when Elastic Transcoder encounters a warning or error condition. For more information, see Create Pipeline.

Response Headers

This operation uses only response headers that are common to most responses. For information about common response headers, see HTTP Responses.

Response Body

When you create a job, Elastic Transcoder returns the values that you specified in the request. For more information, see Settings that You Specify When You Create an Elastic Transcoder Job.

In addition, Elastic Transcoder returns the following values.

(Automatic) Id

The identifier that Elastic Transcoder assigned to the job. You use this value to get settings for the job or to delete the job.

(Automatic) Outputs:Id

A sequential counter, starting with 1, that identifies an output among the outputs from the current job. In the Output syntax, this value is always 1.

(Automatic) Outputs:Duration

Duration of the output file in seconds, rounded up.

(Automatic) Outputs:Width

Width of the output file, in pixels.

(Automatic) Outputs:Height

Height of the output file, in pixels.

(Automatic) Outputs:Status

The status of one output in a job. If you specified only one output for the job, Outputs:Status is always the same as Job:Status. If you specified more than one output:

• Job:Status and Outputs:Status for all of the outputs is Submitted until Elastic Transcoder starts to process the first output.

• When Elastic Transcoder starts to process the first output, Outputs:Status for that output and Job:Status both change to Progressing. For each output, the value of Outputs:Status remains Submitted until Elastic Transcoder starts to process the output.

• Job:Status remains Progressing until all of the outputs reach a terminal status, either Complete or Error.

• When all of the outputs reach a terminal status, Job:Status changes to Complete only if Outputs:Status for all of the outputs is Complete. If Outputs:Status for one or more outputs is Error, the terminal status for Job:Status is also Error.

The value of Status is one of the following: Submitted, Progressing, Complete, Canceled, or Error.

(Automatic) Outputs:StatusDetail

Information that further explains Outputs:Status.

(Automatic) Outputs:AppliedColorSpaceConversion

If Elastic Transcoder used a preset with a ColorSpaceConversionMode to transcode the output file, the AppliedColorSpaceConversion parameter shows the conversion used. If no ColorSpaceConversionMode was defined in the preset, this parameter will not be included in the job response.

(Automatic) Status

If you specified more than one output for the job, the status of the entire job. When Elastic Transcoder starts processing a job, the value of Job:Status changes to Progressing and doesn't change until Elastic Transcoder has finished processing all outputs. When processing is complete, Job:Status changes either to Complete or, if any of the outputs failed, to Error.

If you specified only one output for the job, Job:Status is the same as Outputs:Status.

The value of Job:Status is one of the following: Submitted, Progressing, Complete, Canceled, or Error.

Errors

For information about Elastic Transcoder exceptions and error messages, see Handling Errors in Elastic Transcoder.

Note

If a job fails with an Access Denied error, we recommend that you run the Test Role API action to determine what is causing the error. For more information, see Test Role.

Examples

The following example request creates a job that has two outputs.
