摘要
分析了使用构件技术实现媒体播放器的优势:可自动替换解码器、可动态升级等。并以DirectShow为例,说明构件媒体播放器的实现方法。通过对DirectShow的深入分析(同步问题和控制问题),简化改进DirectShow,提出一套新的基于构件的媒体播放器的接口定义和实现方案。该方案可以支持硬件解码器,而且可以扩展到媒体捕捉方面。
The advantages of media player using component technique, such as automatic replacing decoders and dynamic upgrading, were analysed. With an example of DirectShow, how a media player with component technique works was illuminated. Afterwards, by analysing DirectShow in detail(on synchronization and controlling), DirectShow was simplified and improved, and a new set of interface definition was shown, a scheme of media player was implemented as well. This scheme was proved to be able to support hardware decoder, and be expanded to media capture.
