(void**) &pIAMVideoControl);
/* get flip mode */
status = pIAMVideoControl->GetMode(NULL, &lMode);
/* activate flip mode vertical */
status = pIAMVideoControl->SetMode(NULL, lMode | VideoControlFlag_FlipVertical);
/* deactivate flip mode vertical */
status = pIAMVideoControl->SetMode(NULL, lMode & ~VideoControlFlag_FlipVertical);
/* activate flip mode horizontal*/
status = pIAMVideoControl->SetMode(NULL, lMode | VideoControlFlag_FlipHorizontal);
/* deactivate flip mode horizontal*/
status = pIAMVideoControl->SetMode(NULL, lMode & ~VideoControlFlag_FlipHorizontal);
/* activate flip mode vertical and deactivate flip mode horizontal */
status = pIAMVideoControl->SetMode(NULL, VideoControlFlag_FlipVertical);
/* activate flip mode horizontal and deactivate flip mode vertical */
status = pIAMVideoControl->SetMode(NULL, VideoControlFlag_FlipHorizontal);
