| 摘 要： | 在可伸缩的流媒体系统中,媒体流的发送速度、编码方法可能动态地根据网络性能改变而变化,因此客户端必须根据媒体流的变化来动态调整接收、解码和回放的方法,基于COM组件的FilterGraph技术是解决该问题的方法之一,为了保证流媒体回放的连续性,提出了一种动态调整FilterGraph结构的新方法.

| Abstract: | In a stream media system witch can flex, the sending speed, encoding method can be changed according the performance of the net dynamically. So a stream media client have to change the ways of receiving, encoding and playing to suit the changes of media stream. The technic of FilterOraph basis COM components is one of the ways to deal with this problem. For ensuring the continuity of playback, this paper brought forward a new method to modulate the structure of FilterGraph. |
