Design And Implementation Of Embedded Streaming Media Server

With the popularity of Internet and the development of multimedia applications, streaming media technology is widely used in distance learning, video on demand, broadcast system on Internet, video conference and video communication. Streaming media server is a key platform it is the most important part of streaming media applications. The development cost of embedded streaming media server is low, the server is easy to install and easy to move and easy to use without professional maintenance. Therefore, the embedded streaming media server has a broad market prospect. An embedded streaming media server is designed and implemented based on TIs TMS320DM355 digital media processor.Live555 project is an open source project to provide solutions for streaming media, it can develop streaming media servers quickly, the server can run on many platform, it provides many ideal solutions for embedded streaming media server. The embedded streaming media server is designed and implemented based on the open-source Iive555 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 for playing video between server and clients,the restoration after streaming media server quit unexpectedly. Wireshark and VLC player is used to test the functions of the embedded streaming media server, the server can send video stream correctly and several clients can play the real-time video streaming at the same time with good image and small delay. The server is stable and reliable.
