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

How to Reverse Proxy Traffic to Docker Container on CyberPanel:
https://community.cyberpanel.net/t/reverse-proxy-traffic-to-docker-container-on-cyberpanel/30644
Setup Reverse Proxy:
Open and edit: /usr/local/lsws/conf/httpd_config.conf
extprocessor dockerbackend {
type proxy
address 127.0.0.1:8080
maxConns 100
pcKeepAliveTimeout 60
initTimeout 60
retryTimeout 0
respBuffer 0
}Here “dockerbackend” is a referance name to use later and “8080” is the docker container port.
Use Rewrite Rules to Proxy traffic to your Container:
Now create a website and create the following a .htaccess rewrite rule there.
REWRITERULE ^(.*)$ HTTP://dockerbackend/$1 [P]
If you want to force redirect SSL then use the following:
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
REWRITERULE ^(.*)$ http://dockerbackend/$1 [P]
