A video capture program is proposed, which is applied to various video capture devices with different drive-models. Such a program is able to provide an interface to set the parameters of different capture devices, and work together with DireetShow to reaiize the video capture module of real-time teaching system. Differences among the filter graphs that DirectShow built for different hardwares in the realization of video capture is discussed. The experiments show that the realized video capture modules can set parameters for different ...
