Sometimes you may find that a software package that you would like to use on a CentOS Linux system is unavailable from the default software repositories, aka "repos." In such cases adding alternative repos, such as Extra Packages for Enterprise Linux (EPEL) or RPM Fusion may allow you to locate the desired package. E.g., the VLC media player is available in the RPM Fusion repository, but not the default ones nor in EPEL. RPM Fusion has two separate software repositories, one that contains free and open-source software (FOSS) and another named "nonfree". Packages in the "nonfree" repository still won't cost you anything, but there may be restrictions on the use of the software, e.g., you may be forbidden from using the software for commercial use. The RPM Fusion site defines the nonfree repo as being 'for redistributable software that is not Open Source Software (as defined by the Fedora Licensing Guidelines); this includes software with publicly available source-code that has "no commercial use"-like restrictions.'
To add the "free" repository to a CentOS 7 system, you can issue the
command yum install https://download1.rpmfusion.org/free/el/rpmfusion-free-release-7.noarch.rpm from the root account.
# yum install https://download1.rpmfusion.org/free/el/rpmfusion-free-release-7.n
