SubmitTranscodeJobs - ApsaraVideo VOD - Alibaba Cloud Documentation Center

Submits a transcoding job and starts asynchronous transcoding.

Operation Description

You can transcode a video only in the UploadSucc, Normal, or Checking state.
You can obtain the transcoding result in the StreamTranscodeComplete or TranscodeComplete event notification.
If you initiate an HTTP Live Streaming (HLS) packaging task, you can call this operation to dynamically override the subtitle. If the packaging task does not contain subtitles, we recommend that you do not call this operation to initiate the packaging task. Instead, you can specify the ID of the specific template group when you upload the video. The packaging process is automatically initiated.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters

Parameter	Type	Required	Description	Example
VideoId	string	Yes	The ID of the video.	142710f878bd42508932f660d7b1****
TemplateGroupId	string	Yes	The ID of the transcoding template group used when the video is transcoded. To specify a transcoding template group, you can log on to the ApsaraVideo VOD console and view the ID of the transcoding template group on the Transcode page.	0e408c803baf658ee637790c5d9f****
PipelineId	string	No	The ID of the pipeline.	d3e680e618708erf45fbf2cae7c****
EncryptConfig	string	No	The encryption configurations. The value is a JSON-formatted string. This parameter is required only when HLS encryption is used. Note In the JSON-formatted string of the EncryptConfig parameter, you must set the CipherText parameter to an AES-128 ciphertext key that is generated by calling the GenerateDataKey operation. Otherwise, the transcoding job that uses HLS encryption fails. For more information about how to use HLS encryption, see HLS encryption. Regardless of whether HLS encryption or Alibaba Cloud proprietary cryptography is required, you must enable HLS encryption for the template group that is specified by the TemplateGroupId parameter. Otherwise, HLS encryption cannot be used.	{"CipherText":"ZjJmZGViNzUtZWY1Mi00Y2RlLTk3**", "DecryptKeyUri":"http://demo.aliyundoc.com?CipherText=ZjJmZGViNzUtZWY1Mi00Y2RlLTk3**","KeyServiceType":"KMS"}
OverrideParams	string	No	The parameters used for overriding. The value is a JSON-formatted string. You can set this parameter to override the watermark or subtitle that is associated with the transcoding template. You can override the file URL of an image watermark, the content of a text watermark, the URL of a subtitle file, and the encoding format of a subtitle file. For more information about the data structure, see the "OverrideParams" section of the Media processing parameters topic.	{"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 in all queued jobs. Valid values: 1 to 10. A value of 10 indicates the highest priority. Default value: 6. NoteThis parameter specifies the priority of only the current transcoding job in all queued jobs and does not affect the priorities of jobs that are running.	6
UserData	string	No	The custom configurations, including callback configurations. The value is a JSON-formatted string. For more information, see the "UserData" section of the Request parameters topic. NoteThe callback configurations take effect only when you specify an HTTP callback URL and select specific callback events in the ApsaraVideo VOD console.	{"Extend":{"localId":"**","test":"*"}}
