CentOS 6、7、8安装ffmpeg

安装前请切换root用户，如果是普通用户请在每条命令前添加sudo

1.安装epel扩展源

安装ffmpeg前都需要先安装epel扩展源

yum -y install epel-release

2.安装Nux Dextop Yum 源

由于CentOS没有官方FFmpeg rpm软件包。但是，我们可以使用第三方YUM源（Nux Dextop）完成此工作。

CentOS 6比较简单，安装yum源之后直接安装即可：

su -c 'yum localinstall --nogpgcheck https://download1.rpmfusion.org/free/el/rpmfusion-free-release-6.noarch.rpm https://download1.rpmfusion.org/nonfree/el/rpmfusion-nonfree-release-6.noarch.rpm'
yum -y install ffmpeg ffmpeg-devel

而CentOS 7需额外安装扩展源：

su -c 'yum localinstall --nogpgcheck https://download1.rpmfusion.org/free/el/rpmfusion-free-release-7.noarch.rpm https://download1.rpmfusion.org/nonfree/el/rpmfusion-nonfree-release-7.noarch.rpm'
rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro 
rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm
yum -y install ffmpeg ffmpeg-devel

1) CentOS 7
rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
2) CentOS 6
rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
rpm -Uvh http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-2.el6.nux.noarch.rpm
3) CentOS 8
yum install https://download1.rpmfusion.org/free/el/rpmfusion-free-release-8.noarch.rpm
yum install http://rpmfind.net/linux/epel/7/x86_64/Packages/s/SDL2-2.0.10-1.el7.x86_64.rpm

3.安装FFmpeg 和 FFmpeg开发包

sudo yum install ffmpeg ffmpeg-devel -y
