CreateScreenshotTask

Last updated: 2023-09-06 15:06:20

1. API Description

Domain name for API request: live.tencentcloudapi.com.

This API is used to create a screencapturing task that has a specific start and end time and takes screenshots according to the template configured.

  • Note
  1. If the stream is interrupted, screencapturing will stop. However, the task will still be valid before the specified end time, and screencapturing will be performed as required after the stream is resumed.
  2. Avoid creating screencapturing tasks with overlapping time periods. The system will execute at most three screencapturing tasks on the same stream at a time.
  3. Task records are only kept for three months.
  4. The new screencapturing APIs (CreateScreenshotTask/StopScreenshotTask/DeleteScreenshotTask) are not compatible with the legacy ones (CreateLiveInstantSnapshot/StopLiveInstantSnapshot). Do not mix them when you call APIs to manage screencapturing tasks.
  5. If you create a screencapturing task and publish the stream at the same time, the task may fail to be executed at the specified time. After creating a screencapturing task, we recommend you wait at least three seconds before publishing the stream.

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.
