ApsaraVideo VOD:SubmitTranscodeJobs

Last Updated:Jul 21, 2026

Submits a media transcoding job to start asynchronous transcoding.

Operation description

Usage notes

  • Before you use this operation, make sure that you fully understand the billing methods and pricing of ApsaraVideo VOD. Transcoding is a paid feature. For more information about billing, see Transcoding billing.

  • This is an asynchronous operation. After you submit a task, the task ID is returned. The task is not yet complete at this point and enters a queue for asynchronous execution. The final result is sent through a callback notification. You can also call GetTranscodeTask to query the task status.

  • Only videos in the UploadSucc, Normal, or Checking state can be transcoded.

  • To obtain transcoding results, configure callback messages: SingleCompleteEvent and AllCompleteEvent.

  • This operation supports dynamic replacement of subtitle URLs in HLS adaptive bitrate streaming packaging tasks. If the packaging task does not involve subtitle packaging, do not use this operation to initiate the task. Instead, specify the corresponding transcoding template group ID during video upload to automatically trigger the packaging process.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

TemplateGroupId

string

Yes

The ID of the transcoding template group used for video transcoding. To view the template group ID, log on to the ApsaraVideo VOD console and choose Configuration Management > Media Processing > Transcode Template Group.

EncryptConfig

string

No

The encryption configuration. This parameter is a JSON string and is required only when you use HLS encryption.

Note
  • The CipherText parameter in the EncryptConfig struct must be an AES_128 ciphertext key generated by calling GenerateKMSDataKey. Otherwise, HLS encryption transcoding fails. For more information about the HLS encryption process, see HLS encryption.

  • Regardless of whether you use HLS encryption or proprietary encryption, the templates associated with TemplateGroupId must have the HLS encryption option selected. Otherwise, the content is not encrypted.

OverrideParams

string

No

The override parameters in JSON format. You can use this parameter to override the image watermark file, text watermark content, subtitle file URL, and subtitle file encoding format associated with the transcoding template. For more information about the parameter structure, see OverrideParams.

{"Watermarks":[{"WatermarkId":"af2afe4761992c47dae973374****","FileUrl":"http://developer.aliyundoc.com/image/image.png"},{"WatermarkId":"e8e5b8038d7ada85b376c2707****","Content":"watermark test"}]}

Priority

string

No

The priority of the current transcoding job among all queued jobs.

  • Valid values: 1 to 10.

  • Highest priority: 10.

  • Default value: 6.

Note

The Priority parameter affects only the priority of the current transcoding job among all queued jobs. It does not affect jobs that are already being transcoded.

6

UserData

string

No

The custom settings in JSON format. This parameter supports configurations such as message callbacks. For more information, see UserData.

Note

To use the message callback in this parameter, you must configure an HTTP callback URL and select the corresponding callback event types in the console. Otherwise, the callback settings do not take effect.

{"Extend":{"localId":"****","test":"***"}}

SessionId

string

No

The custom deduplication identifier. If a request with the same identifier was submitted within the past 7 days, the current request returns an error. The value can be up to 50 characters in length and can contain uppercase letters, lowercase letters, digits, hyphens (-), and underscores (_). If this parameter is not specified or is set to an empty string, deduplication is not performed.
