嵌入式流媒体服务器的设计和实现

Design and Implementation of Embedded Streaming Media Server

为了解决嵌入式环境下的视频传输,提出了一个嵌入式流媒体服务器的应用设计方案。采用了流媒体传送技术、控制协议技术、进程间通信技术,使用开放源码流媒体服务器live555项目设计和实现了一个嵌入式流媒体服务器,解决了四个技术问题:管道读写视频操作问题,服务器传送视频控制字问题,服务器与客户端视频播放控制协议问题,流媒体服务器异常退出后恢复问题。该流媒体服务器能够正确传输视频数据,客户端能够播放实时视频,播放画面图像质量高、时延小、稳定可靠。

Present an embedded streaming media server application design for solving the problem of embedded video streaming.The embedded streaming media server is designed and implemented by open-source multimedia server live555 project using streaming media technology,control protocol technology and interprocess communication technology.Four problems are sovled,that is the operation of reading and writing video in pipe,the sending video control words by server,the control protocols of playing video between server and client,the restoration after streaming media server quit unexpectedly.The server can stream video exactly and client can play the real-time video streaming with good image and small delay.The system is stable and reliable.
