Capture screenshots

Cloud Recording service supports taking screenshots during recording, and screenshots are saved in JPG format.

This document describes how to take video screenshots by using the cloud recording APIs.

Implementation

To capture screenshots, set the OutputFileFormat to jpg when calling the StartRecord method. You can also set the interval as needed by setting the SnapshotInterval parameter. The service takes a screenshot of all streams every 10 seconds by default.

You can call the DescribeRecordStatus method to query screenshot task related information, but the file list will not be returned.

The captured screenshots during recording will be uploaded to your third-party cloud storage, and you will receive a notification through a callback every time a screenshot task is completed.
