下载源码包：http://ffmpeg.org/releases/ffmpeg-3.2.2.tar.bz2

解压并安装

tar -jxvf ffmpeg-3.2.2.tar.bz2

进入目录并执行./configure --enable-shared --prefix=/usr/local/ffmpeg

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.
