| Abstract: | This paper introduces the principles of video capture with VFW technology under Windows, and then explains the process of real-time video capture using AVICap window class, especially the technology of displaying the real-time video data by DrawDib function. A C + + class that encapsulates the functions of capturing, encoding, displaying of single video frame is designed. Finally the instances of the programming of VC + + . NET are provided , which offers a new method of software gathering, video capturing, transmission, file management and displaying for video signals. |
