Interface (AVScreenCaptureRecorder)

AVScreenCaptureRecorder is a class for screen capture management. It provides APIs for screen capture. Before calling any API in AVScreenCaptureRecorder, you must use createAVScreenCaptureRecorder() to create an AVScreenCaptureRecorder instance.

NOTE

The initial APIs of this module are supported since API version 6. Newly added APIs will be marked with a superscript to indicate their earliest API version.

The initial APIs of this interface are supported since API version 12.
