下载之后，解压安装包会得到如下目录：

bin
doc
LICENSE.txt

添加到环境变量

在此电脑界面下 右击选择属性 > 高级系统设置 > 环境变量

在用户环境变量 双击 path，选择新建（注意不要更改其他环境变量），将解压缩的 bin 路径粘贴进去

记得点下方的确定，再关闭当前窗口再点确定以保存

到这里，ffmpeg 的配置就差不多了，调用命令行（windows+R输入cmd）输入 ffmpeg -version，如果出现如下说明配置成功

Linux 安装

官网下载地址：https://www.johnvansickle.com/ffmpeg/old-releases/

1. 下载解压

   wget http://www.ffmpeg.org/releases/ffmpeg-3.1.tar.gz
   tar -xvf ffmpeg-3.1.tar.gz

2. 进入解压后目录，输入如下命令 /usr/local/ffmpeg 为自己指定的安装目录

   cd ffmpeg-3.1
   ./configure --prefix=/usr/local/ffmpeg
   make && make install

3. 配置变量

   vi /etc/profile
   # 在最后PATH添加环境变量：
   export PATH=$PATH:/usr/local/ffmpeg/bin
   
   # 保存退出，查看是否生效
   # 设置生效
   source /ect/profile

4. 查看版本

   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
