The Nux repository depends on the EPEL software repository. If the EPEL repository is not enabled on your system, enable it by typing:
sudo yum install epel-release
Next, enable the Nux repository’s and import it’s GPG key:
sudo rpm -v --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
Once the repository is enabled, install FFmpeg:

When converting audio and video files with
ffmpeg you do not have to specify the input and output formats. The input file format is auto detected and the output format is guessed from the file extension.
Convert a video file from mp4 to webm:
ffmpeg -i input.mp4 output.webm
Convert an audio file from mp3 to ogg:
ffmpeg -i input.mp3 output.ogg
When converting files you can specify the codecs you want to use with the
-c option. The codec can be the name of any supported decoder/encoder or a special value
copy which simply copies the input stream.
Convert a video file from mp4 to webm using the
libvpxvideo codec and
ffmpeg -i input.mp4 -c:v libvpx -c:a libvorbis output.webm
Convert an audio file from mp3 to ogg encoded with the
ffmpeg -i input.mp3 -c:a libopus output.ogg
You have successfully installed FFmpeg on your CentOS 7. You can now visit the official FFmpeg Documentation page and learn how to use FFmpeg to convert and your video and audio files.
