摘要
针对多媒体播放器MPlayer在嵌入式Linux平台上没有图形用户界面的现状,为其设计了一款基于Qt的图形用户界面。首先介绍了Qt编程相关知识,然后详细介绍了图形用户界面软件的设计和实现。该图形用户界面具有选择文件、播放控制、时间显示、音量调节等功能。实验结果表明,该图形用户界面可以稳定地运行在嵌入式Linux平台下,且所设计的功能都能很好地实现。
In the view of the status that none of a GUI is existing for MPlayer running on the embedded Linux platform, a GUI based on Qt is designed in this paper. First of all, some knowledge about Qt prograrmning is introduced, and then the design and implementation of GUI software are introduced detailed. The GUI has some functions such as files select, playback control, time display, volume adjustment and so on. The experimental results show that the GUI runs stably on the embedded Linux platform and all of the functions designed have good performance.
