In recent years,the rapid development of the digital video industry,digital video cameras become an important part in people's lives gradually. Meanwhile, the video format and encoding mode also increases. However, the advent of FFMPEG promotes the conversion between audio and video. How to install and compile FFMPEG under the Linux operating sys- tem,and how to use FFMPEG platform to convert between video formats are studies in this paper. High production efficiency, simple configuration and strong fault-tolerant are the main features of the video converter and release. The system can also com- press video,has high compression efficiency,and can significantly improve the network transmission efficiency.%最近几年，数字视频行业的发展飞速，数字视频摄像机逐渐成为人们生活中一个重要的组成部分。与此同时，视频的格式与编码方式也随之增加，FFMPEG的问世促进了音视频之间的转换。在此主要研究在Linux操作系统下如何进行FFMPEG的安装、编译，如何利用FFMPEG平台进行视频格式间的转换，生产效率高、配置简单、容错性强是该视频转换与发布的主要特点，同时系统还可以对视频进行压缩，且压缩效率很高，能够明显提高网络传输效率。
