CreateCloudSliceTask

1. API Description

Domain name for API request: trtc.intl.tencentcloudapi.com.

API description:
This API is used to enable the cloud slicing feature, completing audio and video slicing tasks in the room, and uploading them to the specified cloud storage.
This API is used to achieve the following goals:

This API is used to specify the slicing parameter (SliceParams) to define the blocklist or allowlist of the anchors that require slicing.
This API is used to specify the storage parameter (SliceStorageParams) to specify the cloud storage you want to upload to. Currently, Tencent Cloud Object Storage (COS) and third-party AWS are supported.

A maximum of 20 requests can be initiated per second for this API.

We recommend you to use API Explorer

Try it

API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

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 Name	Required	Type	Description
Action	Yes	String	Common Params. The value used for this API: CreateCloudSliceTask.
Version	Yes	String	Common Params. The value used for this API: 2019-07-22.
Region	Yes	String	Common Params. For more information, please see the list of regions supported by the product. This API only supports: ap-singapore, eu-frankfurt.
SdkAppId	Yes	Integer	SdkAppId of TRTC, which is the same as the SdkAppId corresponding to the TRTC room.
RoomId	Yes	String	RoomId of TRTC, which is the RoomId corresponding to the TRTC room.
UserId	Yes	String	Chatbot's UserId, which is used to enter the room and initiate a slicing task. [*note] This UserId should not be duplicated with the UserIds of the current anchors or audience members in the room. If multiple slicing tasks are initiated in one room, the chatbot's UserId should also be unique; otherwise, the previous slicing task is interrupted. It is recommended to include the room ID as part of the UserId, ensuring that the chatbot's UserId is unique in the room.
UserSig	Yes	String	Signature verification corresponding to the chatbot's UserId, namely, the UserId and UserSig serve as the login password for the chatbot to enter the room. For specific calculation methods, see TRTC solution for calculating UserSig.
SliceParams	Yes	SliceParams	Control parameters for cloud slicing.
SliceStorageParams	Yes	SliceStorageParams	Parameters for uploading cloud slicing files to the cloud storage.
RoomIdType	No	Integer	Type of the TRTC room number. [*Note] It should be the same as the type of the RoomId corresponding to the recording room. 0: string type; 1: 32-bit integer type (default value). Example value: 1.
ResourceExpiredHour	No	Integer	Validity period for calling the API, which starts upon successful initiation of recording and obtaining the task ID. After the timeout, APIs such as querying, updating, or stopping cannot be called, but the recording task is not stopped. The unit of the parameter is hours, with a default value of 72 hours (3 days). The maximum value is 720 hours (30 days), while the minimum value is 6 hours. For example, if this parameter is not specified, the validity period for calling the querying, updating, and stopping recording APIs is 72 hours upon the successful start of recording. Example value: 24.
PrivateMapKey	No	String	TRTC room permission encryption string, which is required only when advanced permission control is enabled in the TRTC console. After enabling, the TRTC backend service system verifies a "permission ticket" called [PrivateMapKey], which contains an encrypted RoomId and an encrypted "permission bit list". Since the PrivateMapKey includes the RoomId, the specified room cannot be entered if only UserSig is provided and PrivateMapKey is not provided. Example value: eJw1jcEKgkAURX9FZlvY****fL9rfNX4_.

3. Output Parameters

Parameter Name	Type	Description
TaskId	String	Task ID assigned by the cloud slicing service. It is a unique identifier for the lifecycle of a slicing task, which loses its significance after the task is completed. The task ID needs to be retained by the business system as a parameter for future operations related to this task.
RequestId	String	The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.

4. Example

Example1 Creating a Slicing Task

This example shows you how to start a cloud slicing task for the specified room (room number: 150) with SdkAppId 200806.
This example shows you how to set the idle time for the room to 30 seconds.
This example shows you how to set the slicing mode to audio slicing + video frame extraction.
This example shows you how to slice the audio every 15 seconds.
This example shows you how to extract a video frame every 5 seconds.
