摘　　要：在媒体资源管理系统设计中,为了设计高效、低成本编码转换子系统,可以利用开源软件FFmpeg来完成设计。FFmpeg拥有丰富的音视频解码器和编码器,可以有效快速地完成多种编码的转换。设计中利用管道完成进程之间的数据通信,利用线程完成转换过程的控制,通过分析进程信息来传递控制信息,有效地完成了两个系统的接口,是一种性价比较高的编码转换设计思路。In the media asset management systems,the high-efficient and low-cost code conversion subsystem can be designed with open source software FFmpeg,which has abundent audio video decoder and encoder,and can complete various code conversion effectively.The data communication between processes is completed with pipes in the design.The control of converting process is achieved by thread.The control information is transmitted through the analysis process information.The interface of the two systems is effectively finished.It is a high cost performance design idea for code conversion.
