基于 DirectShow的通用多路视频接口研究和实现

本文在多路视频监控系统背景下，主要研究和实现了基于DirectShow架构且能响应视频区域鼠标消息的通用多路视频接口，并成功地把该接口应用于该多路系统中。本文设计 的接口，不需要考虑视频捕获硬件的差异，可同时处理多路视频（播放、暂停、捕获和视频区域任意切分），并接受用户直接在视频区域的鼠标操作，灵活控制各路视频。该
该接口提供一个函数和二个类，以MFC扩展DLL的形式封装。

Study and Implementation of the DirectShow- Based Universal Video Interface

A universal DirectShow-based video interface,which can respond to the mouse message from the video region,is studied,implemented,and successfully applied in the multi-channel video monitor system.Regardless of the various video capturing hardware,the interface can handle multi-channel video(such as play,pause,capture,clip window) at the same time and enable the user to use a mouse in the video region and immediately control the video flexibly.The interface,which is encapsulated in MFC Extension DLL,provides one public function and two classes.
