An Openframeworks screen capture application for Microsoft Windows.
- Captures the visible desktop at high speed using the Desktop Duplication API.
- Captures the region of the desktop under the application window.
- Captures individual windows using GDI.
Two Spout senders are created, one for the entire desktop and one for the selected region or application window. A region of interest is always part of the “visible” desktop, so can be obscured by other windows. Window capture is independent and the selected application can be obscured without affecting the capture. The capture continues if SpoutCapture is minimized. Download the package from releases.
