SCStreamOutputType.screen
An output type that represents a screen capture sample buffer.
Declaration
case screenDiscussion
This output represents a sample buffer that wraps a CVPixelBuffer backed by an IOSurface.
The width, height, and pixel format of the sample buffer reflect what you define in SCStreamConfiguration. When capturing multiple windows, the system bases the width and height on the display you pass in through SCContentFilter. You can set a background color for multi-window sample buffers by setting backgroundColor; otherwise the default color is black.
