Changing a Video Capture Setting

  • Article

The following example uses the capCaptureGetSetup and capCaptureSetSetup macros to change the capture rate from the default value (15 frames per second) to 10 frames per second.

CAPTUREPARMS CaptureParms;
float FramesPerSec = 10.0;

capCaptureGetSetup(hWndC, &CaptureParms, sizeof(CAPTUREPARMS));

CaptureParms.dwRequestMicroSecPerFrame = (DWORD) (1.0e6 / 
    FramesPerSec);
capCaptureSetSetup(hWndC, &CaptureParms, sizeof (CAPTUREPARMS));
