| 摘 要： | 针对传统嵌入式多媒体播放器的局限性,本文提出了将用户界面和后台控制系统共同集成的嵌入式多媒体播放器通用控制系统(MediaFrame);基于嵌入式Linux操作系统,采用Qt/embedded图形开发工具完成播放界面的模块化设计,并对模块间通讯机制实现方法进行了详细论述;采用MPlayer作为后台播放控制系统,利用管道通信完成控制命令的响应,实现播放系统的所有功能。实践证明,该系统功能强大、界面友好、可移植性良好。

| Abstract: | Aiming at the disadvantages of the traditional embedded multimedia players, the design of an embedded multimedia playing system based on the integration of GUI and the control system is proposed. An embedded Linux operating system and the Qt/embedded tool are adopted to complete the module design of the playing interface, and the communications between the modules are illuminated particularly. MPlayer is adopted as the background control system, and all functions of the playing system are carried out based ... |
