题目：基于 ARM 的 Linux 多媒体播放器的设计与实现系 （部）：光学与电子信息学院专 业 班：电子科学与技术姓 名：学 号：指导老师： 2025 年 6 月摘 要当今社会是一个信息化的社会。嵌入式技术在这个时代得到了日新月异的进展 。嵌入式技术已经引起了世界各国的高度关注。在这个背景下，本文提出了一种基于嵌入式 ARM9-Linux 的多媒体播放器的设计与实现方案。本文首先介绍了 S3C2440开发板的硬件情况，嵌入式 Linux 操作系统在 ARM 微处理器上的移植技术，包括Linux 系统环境建立，交叉编译环境的建立、引导程序 vivi 的烧写、移植嵌入式Linux 内核，以及添加了 Qtopia 的根文件系统的建立。最终实现了 Linux 到S3C2440 开发板的移植。在此基础上通过移植多功能视频播放器 Mplayer 实现视频文件的播放，最后列举了编译 mplayer 常见问题及解决方法，分析了 mplayer 的工作流程。关键词： 交叉编译环境 ARM9-Linux 多媒体播放器 移植 mplayer AbstractThe contemporary world is an informationalized society. Embedded technology has achieved enormous development by leaps and bounds in this age, and raised great concerns of countries around the world. Under this background, this paper puts forward a scheme of design and implementation of the media player based on embedded ARM9-Linux of. The paper introduces the hardware of the S3C2440 development board and the technology of transplanting embedded Linux operating system into the ARM microprocessor, including the establishment of Linux system environment and cross-compiling environment, the establishment of the loader vivi and the application of the embedded Linux transplant kernel, and adds the Qt root file system building. On this basis, by transplanting versatile video player, the writer accomplish playing video files, list the frequently asked questions and the solutions of compiling mplayer and analyze the workflow of mplayer at last.Key Words：cross-compiling environment media player based on embe...
