摘要
实现了在微软DirectX SDK基础上利用DirectShow和COM组件技术快速开发USB Source Filter。首先介绍了DirectShow体系结构和有关的USB知识,然后以USB Source Filter为例研究了如何开发DirectShow支持的Filter组件,以此为基础结合其它多媒体中间件即可快速构建远程监控、实时图像传输等流媒体系统。
A USB Source Filter based on the Microsoft DirectShow is developed. First the DirectShow architecture and USB are described briefly, and then how to develop the DirectShow filter using the USB source filter is descussed as an example. Based on this filter and other multimedia middleware, a streaming media application system like remote surveillance and real time image transmitting can be quickly constructed.
