startScreenCaptureBySourceType
Starts screen capture.
Future<void> startScreenCaptureBySourceType(
{required VideoSourceType sourceType,
required ScreenCaptureConfiguration config});
Details
This method, as well as startScreenCapture, startScreenCaptureByDisplayId, and startScreenCaptureByWindowId, can all be used to start screen capture, with the following differences:
- startScreenCapture only applies to Android and iOS, whereas this method only applies to Windows and iOS.
- startScreenCaptureByDisplayId and startScreenCaptureByWindowId only support capturing video from a single screen or window. By calling this method and specifying the sourceType parameter, you can capture multiple video streams used for local video mixing or multi-channel publishing.
Attention:
- This method applies to the macOS and Windows only.
- If you call this method to start screen capture, Agora recommends that you call stopScreenCaptureBySourceType to stop the capture and avoid using stopScreenCapture.
Parameters

-
The type of the video source. See VideoSourceType.
Note:- Windows supports up to four screen capture video streams.
- macOS supports only one screen capture video stream. You can only set this parameter to
videoSourceScreen(2).

Exceptions
When the method call succeeds, there is no return value; when fails, the AgoraRtcException exception is thrown; and you need to catch the exception and handle it accordingly.
