Cloud Linux FFMPEG installation : how to install ffmpeg in cloud linux

FFMPEG is not included in cPanel. It's a 3rd party service. So we don't provide support for it.
Please note that we are only your license provider, not your server managers.
Anyway, you can install FFMPEG using the following instruction. But please note that you should use this instruction on your own risk. We don't take any responsibility if it doesn't work:

RUN THESE COMMANDS AS ROOT
Install epel-release

yum install epel-release -y

Update the OS

yum update -y

Reboot the server

shutdown -r now

Run the following commands

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