ffmpeg安装
1、下载解压

tar -zxvf ffmpeg-4.3.2.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-4.3.2
./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
source /etc/profile 设置生效
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 olve 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
