Design and realization of data source filter based on buffer reading

DirectShow是微软公司提供的一套在Windows平台上进行流媒体处理的开发包,与DirectX开发包一起为多媒体流的捕捉和回放提供了强有力的支持,DirectShow是基于一种叫做Filter的组件进行开发和设计的,微软公司提供了许多的数据源Filter以供使用,但是却没有提供对于基于缓冲区中读取数据的Filter阐述了如何利用DirectShow技术来开发和设计这种从缓冲区读取数据的Filter,以方便对多媒体数据的处理。

DirectShow is a developing packet dealing with lnuhimedia stream on Windows platform provided by Microsoft, which is based on filter components. Microsoft offers many data source filters to customers, but nut including reading data based on buffer.
