利用Directshow进行流媒体播放架构的研究与实现
摘要
随着网络技术、计算机技术、数字压缩技术的飞速发展，流媒体的发展步入了1个令人欢欣鼓舞的阶段。流媒体的应用与日俱新，越来越受到大众的欢迎。它广泛的应用于远程教育、数字图书馆、远程医疗、视频点播等网络信息服务的方方面面。流媒体广泛的应用前景及潜在的商业价值使得众多的公司开发自己的流媒体系统。
本文通过对流媒体技术和DirectShow技术的`研究，设计与实现了1种可播放本地多媒体数据流的播放器。该播放器理论上可以播放任何类型的媒体文件（只要系统注册了相应的解码Filter）。在播放媒体文件过程中，可以通过播放界面上的按钮或“控制”菜单下的子菜单项进行各种播放控制，包括：播放、暂停、停止、实现静音播放、音量大小调节、声道平衡设置、快放、慢放、全屏播放、截图功能等。

The Researching and Implementation of Streaming Media Player by Directshow
Abstact
With the rapid development of network technology, computer technology and digital compression technology, streaming media applications are getting more and more popular and have entered an exciting era, which will enormously impact on our daily life. Streaming media is widely used in every aspect of Internet information services, such as distance learning, digital library, distance medical treatment and video-on-demand. It has so many applications and so great business opportunities that many companies are researching and developing their products in this area.
According to the study of Streaming Media technology and DirectShow, a streaming media player which can play multimedia date streaming is designed and implemented in this thesis. This player can play all kinds of media files (if the relative Uncode Filter is regidited in the operating system).In the process of playing, various playing controls can be taken by the button in the interface or the submenus under the menu of “control”. This controls include play, pause, stop, playing voicelessly, set volume, set play rate, set full screen, grab picture and so on.
