# 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/bin export 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

若出现

configure: error: no acceptable C compiler found in $PATH

执行  yum install gcc

结束！
