FFMPEG is a major multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play various audio and video files in different formats. FFMPEG is a very fast video and audio converter that can also grab from a live audio/video source. It can also convert between arbitrary sample rates and re-size video on the fly with a high quality polyphase filter. It is supported by various library files like libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale and libswresample.
libavcodec - an audio/video codec library
libavutil - utility library to aid portable multimedia programming
libavformat - library which provides framework for multiplexing and multiplexing video/audio and subtitle streams
libavfilter - library which enhances a generic audio/video filtering
libavdevice - library which provides a framework grabbing from and rendering to many common multimedia input/output devices framework
libswscale - library enhancing highly optimized image scaling and colorspace and pixel format conversion operations
libswresample - library promoting audio resampling, rematrixing and sample format conversion operations
In short, it is a free software available with libraries and programs to handle multimedia data. It can also be used as a commandline tool in PHP and other programming languages for transcoding multimedia files.
Installation Steps for FFMPEG
We need to install a suitable repofile which includes this FFMPEG package which is the most important step of this installation.
I've tried various repos like RPMforge, EPEL and Webtatic repos in CentOS 7, but these repos lacked FFMPEG packages. Hence, I tried a new repo which is called Nux Dextop. Let's walk through the installation steps.
1. Enable Nux Dextop repo on CentOS 7
It is a third-party RPM repository that contains many popular multimedia related packages for CentOS releases. This repo work only if EPEL repo is enabled in the server. So you need to first make sure that you've enabled EPEL repo.
This is how we install EPEL repo on a CentOS 7 server.
#Install EPEL repo
yum -y install epel-release
After enabling epel repo, go ahead and install Nux Dextop repository.
root@server1 [~]# rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
root@server1 [~]# rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm

root@server1 [~]#***IMPORTANT ***
Nux Dextop repository is an architecture independent RPM, so you can install the same RPM on both 32-bit and 64-bit.
We can now verify that the Nux Dextop repository is installed successfully.
2. Install FFMPEG and FFMPEG devel packages
By installing these packages, all the libraries will be installed in parallel.

Now we have completed with the installation of ffmpeg. You see how simple to install it when we move on the right track.
I will give you an example for converting a mp3 file to oog format using this module on CLI.
Download an mp3 file and execute the ffmpeg command to convert the mp3 file to ogg format.

Now our MP3 test file is converted to Vorbis (ogg) audio compression format which is much better compared to mp3.
Similarly, we can encode, decode and convert any video, images or audio file formats using this commandline tool. We can even make use this module in PHP by proper coding. You can get more information on using this tool by referring to the manual page which you can get by running the command "man ffmpeg".
root@server1 [~]# man ffmpeg
I hope you enjoyed reading this documentation on FFMPEG. I would recommend your valuable suggestions and comments on this!
Have a Nice Day :)
