摘要
随着计算机性能和网络通信技术的发展,人们开始借助于网络浏览信息、交换数据和商业交易。而图像、视频等多媒体业务已逐渐成为信息处理领域中主要的信息媒体形式。微软公司为软件开发人员提供了一个专门用于视频开发的工具包VFW。同时给出了其他几种捕捉视频的方法与采用VFW方法相比较。
Windows Socket在网络编程方面发挥着很大的作用,在VC6.0编程环境下无论设计网络数据传输程序还是网络嗅探器都是简洁高效的。在传输数据时应注意网络传输的安全性问题,避免重要信息(如用户名、密码)的泄露。
本文介绍了基于Windows Socket的网络数据传输,TCP和UDP协议,同时对 Video for windows 软件中AVICap窗口类提供的主要函数和功能进行描述,以及如何使用AVICap窗口类进行视频捕捉。主要阐述了使用VC++6.0进行软件开发,利用VFW软件开发视频应用程序的基本原理,设计在WINDOWS平台实现基于VFW的视频采集压缩传输与播放系统。本文给出了部分代码。

Abstract
Along With the computer performance and development of network communication development, people start with network browsing information 、data exchange and business transactions. Image, video and so on multimedia services has become the main information processing information media forms. Microsoft for software developers to provide a video devoted to the development of the tool kit VFW. Also given several other video capture methods and methods used VFW comparison.
Windows Socket plays an important role in network programming. in VC++6.0 environment,It’ all
Concise and effective No matter design network data transmission program or network sniffer. In data transmission should pay attention to the safety of network transmission, Avoid important information (such as the user name and password) Leakage.
This paper introduces based on the network data transmission ,TCP and UDP protocol ,Also Description on Video for Windows software AVICap window class for the main function and function, as well as how to use AVICap window class for video capture. Mainly expounds using VC++ 6.0 software development, and using VFW software to develop the basic principle of video applications, Design how to realize the system based on the collected VFW video compression transmission and broadcast in WINDOWS platforms. This paper presents some of the code.
