Installing FFmpeg on CentOS 8
FFmpeg is not available in the default CentOS 8 repositories. You can choose to build the FFmpeg tools from the source or to install it using dnf from the Negativo17 repository. We’ll go with the second option.
Complete the following steps to install FFmpeg on CentOS 8:
The Negativo17 repository depends on the EPEL and PowerTools repositories. Run the following commands as root or user with sudo privileges to enable the required repositories:
sudo dnf install epel-release dnf-utils
sudo yum-config-manager –set-enabled PowerTools
sudo yum-config-manager –add-repo=https://negativo17.org/repos/epel-multimedia.repo
Once the repositories are enabled, install FFmpeg:
sudo dnf install ffmpeg
Verify the FFmpeg installation by checking its version:
At the time of writing this article, the current version of FFmpeg available in the Negativo17 repository is 2.8.15.
ffmpeg version 4.2.2 Copyright (c) 2000-2019 the FFmpeg developers
built with gcc 8 (GCC)
The command will also show the FFmpeg configuration options.
That’s it. FFmpeg has been installed on your CentOS machine, and you can start using it.
In this section, we will look at some basic examples on how to use the ffmpeg utility.
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, use the -c option to specify the codecs. It can be a name of any supported decoder/encoder or a special value copy that simply copies the input stream.
Convert a video file from mp4 to webm using the libvpx video codec and libvorbis audio codec:
ffmpeg -i input.mp4 -c:v libvpx -c:a libvorbis output.webm
Convert an audio file from mp3 to ogg encoded with the libopus codec.
ffmpeg -i input.mp3 -c:a libopus output.ogg
We’ve shown you how to install FFmpeg on CentOS 8. You should now visit the official FFmpeg Documentation page and learn how to use FFmpeg to convert and your video and audio files.
