Whether you’re working on video conversion, livestreaming, or audio processing – FFmpeg is an essential tool. But if you’re using AlmaLinux 9.5 on a server with Plesk, FFmpeg isn’t available out-of-the-box through the Plesk Installer.
No worries – here’s a simple, professional way to install FFmpeg system-wide in just a few steps.
✅ Why FFmpeg Isn’t in the Plesk Installer
The Plesk Installer only manages components directly related to the panel – like PHP, MySQL, Apache, and so on. Since FFmpeg is a system-level multimedia tool, it needs to be installed using dnf, AlmaLinux’s package manager.
🛠️ How to Install FFmpeg on AlmaLinux 9.5
Step 1: Enable EPEL and RPM Fusion
These repositories contain additional packages not available in the standard AlmaLinux repo – including FFmpeg.
dnf install epel-release -y
dnf install https://download1.rpmfusion.org/free/el/rpmfusion-free-release-9.noarch.rpm -yStep 2: Install FFmpeg
Once the repositories are added, install FFmpeg and the development libraries:
dnf install ffmpeg ffmpeg-devel -yStep 3: Reboot the Server
While not always required, a quick reboot ensures everything loads cleanly:
rebootStep 4: Check the Installation
After the reboot, log back in via SSH and verify the installation:
ffmpeg -versionYou should now see output showing your installed FFmpeg version and supported codecs.
🤖 Optional: Verify FFmpeg in a Web Environment
