安装EPEL Release，因为安装需要使用其他的repo源，所以需要EPEL支持

yum install -y epel-release

#如果出现缺少Code提示，可以：

sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

#安装完成之后，可以查看是否安装成功
yum repolist
安装Nux-Dextop源
#导入一个Code

sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro

#安装nux-dextop 源

sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm

#查看repo源是否安装成功
yum repolist

yum安装ffmpeg

yum install -y ffmpeg

#安装完成后检查ffmpeg 版本
ffmpeg -version

安装播放器

yum install vlc
yum install mplayer

随便下载个mp4文件

mplayer emacs.mp4

[url]https://github.com/arut/nginx-rtmp-module/wiki/Getting-started-with-nginx-rtmp[/url]


cd /opt/nginx
git clone https://github.com/killinux/nginx-rtmp-module
./configure --add-module=/opt/nginx/nginx-rtmp-module --prefix=/usr/local/nginx

make
make install
