The version of mpv provided by the Ubuntu repositories is obsolete, and not compatible with Karaoke Mugen.
You must thus install another version. mpv's official site provides several ways to install Karaoke Mugen, but the simplest is for Ubuntu and its derivatives to use the following PPA :
sudo add-apt-repository ppa:mc3man/mpv-tests sudo apt-get update sudo apt-get install mpv
Check out mpv's website for more info.
The required mpv version for macOS is 0.25, but to make fullscreen work better, you'll need version 0.27. Install it through your preferred method (macPorts, Homebrew, binaries, etc.)
A version for Raspberry Pi is available through the Mugen Pi Project
