　　研究了采用 DirectShow 技术从音视频设备获取媒体数据并进行后期处理的问题。随着多媒体技术应用的越来越广，用户对多媒体产品的要求也越来越高。早期的多媒体软件与音视频设备高度关联，存在着通用性差、功能扩展难等诸多局限，不能满足用户需求。本文基于DirectShow系统对硬件的充分支持以及硬件设备无关性的特点，提出了一种采用 DirectShow技术的设计方法，解决了多媒体软件受限于设备的问题。经测试表明，该方法达到了预期，在多媒体领域将有良好的应用前景。

The research has adoped the DirectShow technology to get media data from audio and video equipment and solve after-treatment problems. With the increasingly wide application of multimedia technology, users’s requirements of multimedia products are becoming higher and higher. The early multimedia software, highly correlated with audio and video equipment, and with limitations such as poor commonality and the function expansion difficulty, can not meet users’s needs. Based on the characteristics of DirectShow system’s full support to hardware, and hardware's independence, this article has proposed a design method of applying DirectShow technology to solve problems that multimedia software is limited by equipment. Tests show that, the method has a chieved the expectation and will have a good application prospect in the field of multimedia.
