capSetCallbackOnVideoStream
The
capSetCallbackOnVideoStream macro sets a callback function in the application. AVICap calls this
procedure during streaming capture when a video buffer is filled. You can use this
macro or explicitly call the
WM_CAP_SET_CALLBACK_VIDEOSTREAM message.
BOOL capSetCallbackOnVideoStream(
Parameters
hwnd
Handle of a capture window.
fpProc
Address of the video-stream callback function. Specify NULL for this parameter
to disable a previously installed video-stream callback function.
Return Values
Returns TRUE if successful or FALSE if streaming capture or a single-frame
capture session is in progress.
Remarks
The capture window calls the callback function before writing the captured
frame to disk. This allows applications to modify the frame if desired.
If a video stream callback function is used for streaming capture, the
procedure must be installed before starting the capture session and it must remain
enabled for the duration of the session. It can be disabled after streaming
capture ends.
