许多关于视频的软件（如视频会议、可视电话等）开发都应用于视频捕获技术。微软为软件开发人员提供了一个专门用于视频捕获的VFW SDK，从而为在Windows系统中实现视频捕获提供了标准的接口，并大大降低了程序的开发难度。由于VFW SDK只有VC和VB版，没有Delphi版，因此需要在Delphi中一一声明DLL中的各个函数和变量。文中详细介绍了如何利用VFW在Delphi中开发视频捕获程序的步骤，同时给出了程序实例。-many of the video software (such as video conferencing, video telephony, etc.) are applied to the development of video capture technology. Microsoft for software developers with a special video capture for the VFW SDK, for the Windows System Video Capture provides a standardized interface, and greatly reduce the development process more difficult. As VFW SDK only version of VB and VC, no version of Delphi, Delphi in a statement on January 1 of each DLL functions and variables. This paper describes in detail how to use VFW in Delphi development video capture process steps and give examples of the program.
