capVideoStreamCallback

The capVideoStreamCallback function is the callback function used with streaming capture to optionally process a frame of captured video. The capVideoStreamCallback callback function is a placeholder for the application-supplied function name.

LRESULT CALLBACK capVideoStreamCallback(
  HWND hWnd,         
  LPVIDEOHDR lpVHdr  
);
 

Parameters

hWnd

Handle of the capture window associated with the callback function.

lpVHdr

Address of a VIDEOHDR structure containing information about the captured frame.

Remarks

The capture window calls a videostream callback function when a video buffer is marked done by the capture driver. When capturing to disk, this will preceed the disk write operation.
