摘要:

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。

关键词: DirectShow视频接口 消息窗口 多路视频监控 MFC扩展DLL

Abstract:

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 earl handle multi-channel video (s  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 fl lexibly. The interface, which is encapsulated in MFC Extension DLL, provides one public function and two classes.
