基于ARM处理器的流媒体播放器客户端的构建

A building of streaming player client cased on ARM processor

设计了一种新型的嵌入式流媒体的客户端。它以ARM处理器和Linux嵌入式操作系统为平台,通过对原有Mplayer播放器进行RTP/RTSP功能扩展和移植,开发出了一款在ARM开发板上进行实时流播放的嵌入式流媒体播放器。这种播放器不但继承了Mplayer支持多种媒体格式以及丰富的后期处理滤镜等优点,而且即使在主频仅为200M的三星S3C2410 ARM开发板上也能够进行顺畅的流媒体播放,视频流顺畅,画质清晰,给人的感觉如同视频出自本机一般,非常适合应用于嵌入式系统。

A new type of embedded streaming media client is designed in this paper.It takes the ARM processor and embedded Linux operating system as platform,and develops an embedded streaming player which broadcasts in real time streaming on the ARM through the RTP/RTSP extensions and transplantation of the original Mplayer.This player not only inherits advantages of the Mplayer such as supporting multiple media formats and extensive post-processing filters,but also carries out streaming media smoothly even on the Samsung S3C2410 ARM board whose main frequency is only 200M.What＇s more,the video streaming runs like floating clouds and the pictures look like seeing from the mirrors,which makes the feeling that the video is just from the original machine,so this player fits the embedded system very well.
