DXcam

Why we included this project

DXcam is a Windows screen-capture library that returns frames as NumPy arrays, so it fits naturally into computer-vision work and AI agents that need to watch a live desktop. It is built on the Desktop Duplication API, with a Windows Graphics Capture backend as an alternative, and it handles full-screen exclusive Direct3D apps that tend to break simpler screenshot tools. The library is tuned for low-latency, high-FPS grabbing, and it includes the controls real capture pipelines need: region capture, target-FPS pacing with drift correction, a ring buffer for continuous recording, zero-copy frame views, and one camera instance per monitor. If you are collecting training data or logging game telemetry, DXcam gets you from screen to inference loop without a separate capture server.
