How To Install FFmpeg on CentOS 7 / RHEL 7

The RPM Fusion repository depends on the EPEL software repository. If the EPEL is not enabled on your system, enable it by typing:

## RHEL 7
subscription-manager repos --enable rhel-*-optional-rpms \
                           --enable rhel-*-extras-rpms \
                           --enable rhel-ha-for-rhel-*-server-rpms
yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
## CentOS 7
