Installing FFmpeg on Ubuntu
The official Ubuntu repository contains the FFmpeg package which can be installed with the apt package manager. This is the easiest way to install FFmpeg on Ubuntu. A new major version is released every six months, and the versions included in the repository usually lag behind the newest version of FFmpeg.
At the time of writing this article, the current version of FFmpeg available in the Ubuntu 20.04 repositories is 4.2.x. To install it, enter the following command as root or user with sudo privileges:
sudo apt update sudo apt install ffmpeg
To verify the installation, use the ffmpeg -version command, which prints the FFmpeg version:

There he is. FFmpeg is now installed on your system, and you can start using it.
When a new version is released, you can update the FFmpeg package via the command line or your desktop’s Software Update tool.
In this section, we will look at some basic examples of how to use the ffmpeg utility.
When converting audio and video files with ffmpeg, you don’t need to specify the input and output formats. The input file format is detected automatically, and the output format is guessed from the file extension.
- Convert video files from mp4 to webm:
ffmpeg -i input.mp4 output.webm
- Convert audio files from mp3 to ogg:
ffmpeg -i input.mp3 output.ogg
Specifies the codec
When converting files, use the -c option to specify a codec. This can be a supported decoder / encoder name or a copy of a custom value that only copies the input stream.
- Convert video files from mp4 to webm using libvpx video codec and libvorbis audio codec:
ffmpeg -i input.mp4 -c:v libvpx -c:a libvorbis output.webm
- Convert audio files from mp3 to ogg encoded with libopus codec.
ffmpeg -i input.mp3 -c:a libopus output.ogg
