How to enable Windows media foundation hardware acceleration on opencv.

edit

Hi, My OpenCV application uses cv::CAP_MSMF flag for cv::VideoCapture, and in getBuildInformation() is added below. Is the application uses the Windows Media Foundation Hardware acceleration? or do I need to ensure or enable anything in my application.
