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