How to install FFmpeg on CentOS cPanel server:
Step 1: Update the system
sudo yum install epel-release -y
sudo yum update -y
Step 2: Install the Nux Dextop YUM repo
There are no official FFmpeg rpm packages for CentOS for now. Instead, you can use a 3rd-party YUM repo, Nux Dextop, to finish the job.
On CentOS 7, you can install the Nux Dextop YUM repo with the following commands:
sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
For CentOS 6, you need to install another release:
sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-2.el6.nux.noarch.rpm
Step 3: Install FFmpeg and FFmpeg development packages
sudo yum install ffmpeg ffmpeg-devel -y
Step 4: Test drive
Confirm the installation of FFmpeg:

On a CentOS installation over Oracle Cloud, when running dnf or yum, you may get the error:
Invalid configuration value: failovermethod=priority in /etc/yum.repos.d/litespeed.repo; Configuration: OptionBinding with id "failovermethod" does not exist
To solve the issue, using the command line tool sed, we first start off by making a backup of the repository files:
sudo sed -iBAK '/^failovermethod=/d' /etc/yum.repos.d/*.repo
Then we use the sed command again to remove the problematic parameter in the repository files:
sudo sed '/^failovermethod=/d' /etc/yum.repos.d/*.repo
Once you have done it, you can run dnf to check whether the error appears again:
dnf upgrade
