安装过程： 下载安装源，配置，编译，安装，设置环境变量。

# wget http://www.ffmpeg.org/releases/ffmpeg-3.1.tar.gz# tar -zxvf ffmpeg-3.1.tar.gz# cd ffmpeg-3.1# ./configure --prefix=/usr/local/ffmpeg# make && make install等待安装完成...# vi /etc/profile在最后PATH添加环境变量：PATH=$PATH:/usr/local/ffmpeg/binexport PATH保存退出# source /ect/profile   设置生效# ffmpeg -version       查看版本

　　

注意：

若安装过程中出现以下错误：

yasm/nasm not found or too old. Use –disable-yasm for a crippled build.

If you think configure made a mistake, make sure you are using the latest

version from Git. If the latest version fails, report the problem to the

ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.

Include the log file “config.log” produced by configure as this will help

solve the problem.

 

需要安装yasm

# wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz# tar -zxvf yasm-1.3.0.tar.gz# cd yasm-1.3.0# ./configure# make && make install

　　

结束！
