Installation for Linux users
First install the FFmpeg package using either Homebrew or a binary build. Then test that the software is properly installed. (The compilation from the source code is out of the scope of this tutorial.)
Installing the software with Homebrew
- Installing Homebrew
Install Homebrew, a package manger originally designed for macOS, that works now under Linux as well (and actually supersedes Linuxbrew). You can install Homebrew by pasting the following command at a Terminal prompt:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Then add to your configurations file for the terminal sessions (which is usually
~/.zshrc) the following three lines:
echo 'export PATH="/home/linuxbrew/.linuxbrew/bin:$PATH"' >> ~/.bashrc
echo 'export MANPATH="/home/linuxbrew/.linuxbrew/share/man:$MANPATH"' >> ~/.bashrc
echo 'export INFOPATH="/home/linuxbrew/.linuxbrew/share/info:$INFOPATH"' >> ~/.bashrc
After successful installation you should restart the Terminal and execute:
Detailed instructions for Homebrew are posted at:
- Installing FFmpeg
Once Homebrew is installed, for our purpose, we recommend to install the most recent stable FFmpeg release with the following command:1
brew install avpres/formulae/ffmpeg --with-openjpeg --with-rubberband --with-tesseract
If you really need it, you can also install the current FFmpeg development branch with the following command (please note that we generally do not recommend using the development branch in production):
brew install avpres/formulae/ffmpeg --HEAD --with-openjpeg --with-rubberband --with-tesseract
As, sadly, the fascist “America alone” ideology becomes predominant in the open-source community as well, if you need the support of more languages than just English, then you have to run an additional command:
brew install tesseract-lang
- Upgrading FFmpeg with Homebrew
To update Homebrew and upgrade FFmpeg to the most recent stable release, use the following line:
brew update && brew upgrade avpres/formulae/ffmpeg
To update Homebrew and upgrade FFmpeg to the current development branch, use the following line:
brew update && brew upgrade avpres/formulae/ffmpeg --fetch-HEAD
Installing the software from a build
Please follow the instructions given at: ffmpeg.org/download.html
Testing your installation
Once you followed the installation above, you should have the commands ffmpeg, ffplay and ffprobe installed.
Test ffmpeg by pasting into the Terminal the line:
ffmpeg -f lavfi -i mandelbrot -t 10 -pix_fmt yuv420p ~/Desktop/mandelbrot.mkv
This should produce on your Desktop a file of the Mandelbrot pattern.
Test ffplay by pasting into the Terminal the line:
This should play the Mandelbrot file.
Test ffprobe by pasting into the Terminal the line:
ffprobe -show_format -show_streams -print_format json ~/Desktop/mandelbrot.mkv
This should display the Mandelbrot file’s technical metadata.
The recommended parameters are:
- Enables JPEG 2000 encoding and decoding with the OpenJPEG library.
- Enables the Rubberband audio filter, which allows time-stretching and pitch-shifting.
- Enables the Tesseract video filter for optical character recognition, e.g. for extracting intertitles or subtitles.
To see the available options paste into the Terminal the line:
brew options avpres/formulae/ffmpeg
