How to Install FFmpeg on Rocky Linux 9

FFmpeg is a powerful tool for manipulating audio and video files. It can decode, encode, transcode, mux, demux, stream, filter, and play nearly all multimedia files created on any platform. FFmpeg compiles and runs on Linux, Mac OS X, Microsoft Windows, BSD systems, and Solaris. In addition to playing various file formats, FFmpeg also supports several different codecs. This makes it an ideal tool for transcoding files between multiple formats or encoding files for use with specific devices or platforms. Additionally, FFmpeg can be used to create streaming video or audio over the internet. FFmpeg is a versatile and powerful tool in any multimedia enthusiast’s toolkit.

The following tutorial will teach you how to install FFmpeg on Rocky Linux 9 using the RPM Fusion free repository command line terminal.

Update Rocky Linux

First, update your system to avoid any conflicts when installing the package.

sudo dnf upgrade --refresh

Install EPEL/EPEL Next Repository

The first task is to install the EPEL repository, and the recommendation is to install both repositories.

First, enable the CRB repository.

sudo dnf config-manager --set-enabled crb

Next, install EPEL using the following (dnf) terminal command.

sudo dnf install \ \

Install & Enable RPM Fusion Repositories

In the second step, install the RPM Fusion repo’s in your terminal with the following install options below.

Note, if you an open-source fan, only install the free repository. For all other users, install both.

Install/Enable the Non-Free Repository (OPTIONAL)

sudo dnf install$(rpm -E %rhel).noarch.rpm -y

FFmpeg Basic Commands

Below are some basic commands for using FFmpeg. I would recommend visiting the official documentation to see a complete list of examples, as it is pretty extensive.

The primary command usage syntax for FFmpeg is below as an example.

ffmpeg [global_options] {[input_file_options] -i input_url} …{[output_file_options] output_url} …

Note that you will need to use these commands on each new file. There is no saving technique to date.

FFmpeg Conversion Example

To convert audio and video files with FFmpeg, you do not need to specify your command’s input and output formats. Instead, the input file format is auto-detected, and the output is given an output formulated from the file extension.

Convert a video file from mp4 to WebM.

ffmpeg -i existingfile.mp4 newfile.webm

Alternatively, it can also include more output files than just 1.

ffmpeg -i existingfile.wav newfile.mp3 newfile.ogg

Remember to check the list of supported formats using the following command:

ffmpeg -formats

FFmpeg Extract Audio from Video Example

If you want to extract the audio from a video file, this is done with the -vn input.

ffmpeg -i video.mp4 -vn audio.mp3

Note that this will convert the audio to the current bit rate of the original video file.

If you want to specify a new rate, enter the following example command.

ffmpeg -i video.mp4 -vn -ab 128k audio.mp3

Some examples of the most common bit rates are 96k, 128k, 192k, 256k, and 320k.

How to Update/Upgrade FFmpeg

FFmpeg was installed with RPM Fusion using the dnf package manager. This makes maintaining updates simple and quick by running the standard update command as you check your entire system for updates as follows.

sudo dnf update --refresh

How to Remove (Uninstall) FFmpeg

Remove FFmpeg using the following command.

sudo dnf autoremove ffmpeg ffmpeg-devel

Remove autoremove and replace it with remove for users that do not want to remove the unused dependencies from the installation. I would recommend keeping EPEL and RPM Fusion installed, and most users often need multiple packages from these repositories, which are highly used within the community.
