摘要
介绍了在Windows下利用VFW技术实现视频采集的技术原理,及采用AVICap窗口类进行实时视频捕获的步骤;特别提出了利用DrawDib函数处理实时视频数据的回放技术,并且设计了封装单帧视频的捕获、编码、显示等功能的C++类.给出了在VC++NET下的程序实现实例,为视频信号的软件采集、捕获、传输、文件管理及显示提供了一种新的方法.
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.
