摘　　要：针对现有嵌入式Linux终端设备流媒体服务C/S模式的不足,实现了嵌入式Linux终端流媒体服务由C/S模式到B/S模式的改进。解决方法如下:影片参数添加到表单提交参数中,并通过表单提交进行节目点播;嵌入式Linux终端通过监听浏览器行为,截取用户请求信息,判断符合特定表单形式的request行为,并使用本地代码来完成mplayer播放器启动;mplayer接收影片参数,连接流媒体服务器并播放视频。解决了C/S模式下占用资源多、升级维护复杂及用户操作不方便的问题,实现了基于WEB形式的在线流媒体观看。Aiming at the shortage of C/S model in existing streaming media services of embedded Linux terminal equipment,our system,the online steaming media services based on the embedded Linux system,has achieved the transformation from C/S model to B/S model.The solution is as follows： the parameter of films is added to the form submitting parameter,and users request video watching by submitting the forms.The embedded Linux terminals listen to the behaviour of the browser,intercept the request information from users,and determine if the parameter is in accord with specific form＇s request behaviour,and use native code to start the mplayer player.Then the streaming media player receives the film＇s parameter,connects streaming media servers through RTSP protocol,and plays the videos.The system has solved the problems of C/S mode in wasting resources,complexity in upgrading and maintenance,and inconvenient operations,and realises WEB-based online streaming media watching.
