What about mpv --shuffle <dir>?

This covers the basic functionality, but it's not as extendable. In a shell script, you are writing every line, so you can add checks and calls in between any action you want. In mpv, running a script when a file is not found, for example, is way more annoying than just adding a [ -f file ] || myscript
