WM_CAP_GRAB_FRAME_NOSTOP
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.
