Article
02/22/2024

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.

Syntax

void capGrabFrameNoStop(
   hwnd
);

Parameters

hwnd

Handle to a capture window.

Return value

None

Remarks

For information about installing callback functions, see the capSetCallbackOnError and capSetCallbackOnFrame macros.
