嵌入式Linux多媒体播放器的改进及实现

Improvement and implementation of embedded Linux multimedia player

针对现有播放器的功能,以目前流行的嵌入式Linux操作系统及Qtopia环境下的开源多媒体播放器代码为基础,改进原播放器源码,实现了支持包含MP3音频文件和MPEG4视频文件播放的媒体播放器及文件加载模块的多媒体文件浏览功能,通过制作新的播放器皮肤,来美化显示界面。调试结果显示,各种功能在硬件开发平台GT2440上得以验证。

Aimed at the function of the currently used multimedia player,this paper introduces the improvement in original code recoding,drawing on embedded Linux operating system in prevailing use and the multimedia player open-code resource under Qtopia environment.The improvement is associated with both MP3 audio files and MPEG4 video files,and MP3 and MPEG4 media players,along with the browsing function of multimedia files by loading the documents load module and the embellished outlook by modifying the skin of the player.The paper ends with the verification of all functions on the hardware development platform GT2440.
