以主要函数的描述为中心，以主要函数的流程为线索，通过编写管理员界面及予对话框来实现管理及设置服务器功能，实现符合MPEG4标准的音视频数据。分析了流媒体直播服务器的功能需求．利用MPEG4IP编码库实现MPEG4的软编码，设计了流媒体直播服务器的功能。实验显示，采用SDL技术实现了在unux平台显示播放，基于RTP／RTSP协议实现了音视频数据的传榆，效果良好。%The management and server functionality setting is achieved through the main function description, the process of main function as information, writing administrator interface and the dialog box to meet the standards of mpeg4 video data. The functionality requirement of live broadcast streaming media server is analyzed, the code of mpeg4 is implemented with the use of code library mpeg4i, and the functionality of live broadcast streaming media server is designed. The test shows that the effect is good for play in Linux platform with SDL technology.
