FFmpeg is a tool for converting video and audio files.
On Ubuntu 16.04 or 18.04, you can install the ffmpeg command by SSH'ing into your server as root and running the following command:
sudo apt-get install ffmpeg
On Ubuntu 14.04, ffmpeg has been removed and replaced with avconv.
You can install avconv by by SSH'ing into your server as root and running the command:
sudo apt-get install libav-tools
However, avconv has different syntax than ffmpeg so your PHP scripts will need to know how to use avconv, not ffmpeg.
If you need the original ffmpeg command, you can install an unofficial ffmpeg package for Ubuntu 14.04 using the following commands as root.
Be sure to make backups of your server before adding unofficial packages to your server.
sudo apt-add-repository ppa:jon-severinsson/ffmpeg sudo apt-get update sudo apt-get install ffmpeg
Note that this PPA doesn't provide gstreamer-ffmpeg integration.
Please be aware that ServerPilot won't automatically update third-party packages like the ones installed from PPAs. If you install from this PPA, you'll need to perform your own ffmpeg updates using the following command as root:
sudo apt-get dist-upgrade
On Ubuntu 12.04, you can install the ffmpeg command by SSH'ing into your server as root and running the following command:
sudo apt-get install ffmpeg
