WM_CAP_GRAB_FRAME_NOSTOP message
The WM_CAP_GRAB_FRAME_NOSTOP message fills the frame buffer with a single uncompressed frame from the capture device and displays it. Unlike with the WM_CAP_GRAB_FRAME message, the state of overlay or preview is not altered by this message. You can send this message explicitly or by using the capGrabFrameNoStop macro.
