# 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
