摘　　要：随着嵌入式系统的不断发展,嵌入式处理器运算能力不断增强,多媒体组件逐渐成为了系统中不可或缺的重要组成部分。目前已存在几种嵌入式媒体播放器,但并不足以适合不同应用环境的需要。本文介绍了媒体播放器在以嵌入式Linux和图形用户界面Qt为软件平台的设计和实现,提供了对流行的MPEG-1、MPEG-2、MPEG-4、H.263格式文件的支持,提供了对播放控制、播放列表的支持,给出了一个开放的解码器插件接口,并且具有全中文界面。With the development of embedded system, the operation power of embedded processor has been greatly enhanced, the multimedia components are becoming more and more important for the whole system. Although there already exits several media players for embedded system, they can't meet the needs of various application environments. This paper describes the design and implementation of the multimedia player by using embedded Linux and Qt graphics user interface (GUI) as the software platform. It can support popular MPEG-1, MPEG-2,MPEG-4 and H. 263 format files, support VCR and play list, gives an open interface for plug-ins, and has a Chinese UI.
