A small script for controlling mpv via the JSON IPC. Intended to resemble playerctl.

mpvctl

#!/usr/bin/env bash
# This script requires:
# - that the directory $HOME/.mpv exist 
# - that the program socat be installed
# - that you start mpv with the unix socket feature pointing at that directory
#   I recommend an alias in your .bashrc or equivalent file:
#       alias mpv="mpv --input-unix-socket=$HOME/.mpv/socket"

socket="$HOME/.mpv/socket"

command() {
    # JSON preamble.
    local tosend='{ "command": ['
    # adding in the parameters.
    for arg in "$@"; do
        tosend="$tosend \"$arg\","
    done
    # closing it up.
    tosend=${tosend%?}' ] }'
    # send it along and ignore output.
    # to print output just remove the redirection to /dev/null
    echo $tosend | socat - $socket &> /dev/null
}

# exit mpv
[ "$1" = "stop" ] && command 'quit'
# toggle play-pause
[ "$1" = "play-pause" ] && command 'cycle' 'pause'
# start playing
[ "$1" = "pause" ] && command 'set' 'pause' 'yes'
# stop playing
[ "$1" = "play" ] && command 'set' 'pause' 'no'
# play next item in playlist
[ "$1" = "next" ] && command 'playlist_next'
# play previous item in playlist
[ "$1" = "previous" ] && command 'playlist_prev'
# add item(s) to playlist
[ "$1" = "add" ] && shift &&
    for video in "$@"; do
        command 'loadfile' "$video" 'append-play';
    done;

thank you very much for this

Thank you very much, exactly what I was looking for!

Exactly that. Although using --input-unix-socket gave me a warning for possible deprecation in the future. Just needed to change it to --input-ipc-server.

This is probably a small subset of mpvc.

@dwgill nice ❤️

Starting using this script, while nice I wanted more advanced functionality so ported it to Python:

... resolves the issue that paths from add needed to be absolute, mpvctl add *.mp3 would fail for e.g.
