1. 安装 EPEL Release，因为安装需要使用其他的 repo 源。

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，通过下列命令查看是否成功

yum repolist

2. 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

3. yum 安装 ffmpeg

yum install -y ffmpeg

例如：把 mp3 转换成 ogg 可以运行下面的命令行：

wget https://example.com/mpthreetest.mp3
ffmpeg -i mpthreetest.mp3 -c:a libvorbis -q:a 4 mpthreetest.ogg

1. Install EPEL Release because of the denpendence on other repositories.

If it comes with warning -"lacks Code", you can do

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

After installation, you can input following code to see if that works.

yum repolist

2. Install Nux-Dextop repositories.

Import a code:

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

Install nux-dextop repositories.

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

Make sure if that works.

yum repolist

3. Use yum to install ffmpeg.

yum install -y ffmpeg

eg. You can use following code to convert mp3 files into ogg format.

wget https://example.com/mpthreetest.mp3
ffmpeg -i mpthreetest.mp3 -c:a libvorbis -q:a 4 mpthreetest.ogg
