Playerctl

For true players only: spotify, vlc, audacious, bmp, xmms2, and others.

About

Playerctl is a command-line utility and library for controlling media players that implement the MPRIS D-Bus Interface Specification. Playerctl makes it easy to bind player actions, such as play and pause, to media keys.

For more advanced users, Playerctl provides an introspectable library available in your favorite scripting language that allows more detailed control like the ability to subscribe to media player events or get metadata such as artist and title for the playing track.

Using the CLI

playerctl [--version] [--list-all] [--all-players] [--player=NAME] COMMAND

Pass the name of your player with the --player flag, or select all available players with the --all-players flag. You can find out what players are available to control with the --list-all switch. If no player is specified, it will use the first player it can find.

Here is a list of available commands:

  play                    Command the player to play
  pause                   Command the player to pause
  play-pause              Command the player to toggle between play/pause
  stop                    Command the player to stop
  next                    Command the player to skip to the next track
  previous                Command the player to skip to the previous track
  position [OFFSET][+/-]  Command the player to go to the position or seek forward/backward OFFSET in seconds
  volume [LEVEL][+/-]     Print or set the volume to LEVEL from 0.0 to 1.0
  status                  Get the play status of the player
  metadata [KEY]          Print metadata information for the current track. Print only value of KEY if passed.

Using the Library

To use a scripting library, find your favorite language from this list and install the bindings library.

Example Python Script

This example uses the Python bindings.

#!/usr/bin/env python3

from gi.repository import Playerctl, GLib

player = Playerctl.Player(player_name='vlc')

def on_metadata(player, e):
    if 'xesam:artist' in e.keys() and 'xesam:title' in e.keys():
        print('Now playing:')
        print('{artist} - {title}'.format(artist=e['xesam:artist'][0], title=e['xesam:title']))

def on_play(player):
    print('Playing at volume {}'.format(player.props.volume))

def on_pause(player):
    print('Paused the song: {}'.format(player.get_title()))

player.on('play', on_play)
player.on('pause', on_pause)
player.on('metadata', on_metadata)

# start playing some music
player.play()

if player.get_artist() == 'Lana Del Rey':
    # I meant some good music!
    player.next()

# wait for events
main = GLib.MainLoop()
main.run()

Installing

First, check and see if the library is available from your package manager (if it is not, get someone to host a package for you) and also check the releases page on github.

Using the cli and library requires GLib (which is a dependency of almost all of these players as well, so you probably already have it). You can use the library in almost any programming language with the associated introspection binding library.

Additionally, you also need the following build dependencies:

gobject-introspection for building introspection data (configurable with the introspection meson option)

gtk-doc for building documentation (configurable with the gtk-doc meson option)

Fedora users also need to install redhat-rpm-config

To generate and build the project to contribute to development and install playerctl to /:

meson mesonbuild
sudo ninja -C mesonbuild install

Note that you need meson >= 0.46.0 installed. In case your distro only has an older version of meson in its repository you can install the newest version via pip:

pip3 install meson

Also keep in mind that gtk-doc and gobject-introspection are enabled by default, you can disable them with -Dintrospection=false and -Dgtk-doc=false.

If you don't want to install playerctl to / you can install it elsewhere by exporting DESTDIR before invoking ninja, e.g.:

export PREFIX="/usr/local"
meson --prefix="${PREFIX}" --libdir="${PREFIX}/lib" mesonbuild
export DESTDIR="$(pwd)/install"
ninja -C mesonbuild install

You can use it later on by exporting the following variables:

export LD_LIBRARY_PATH="$DESTDIR/${PREFIX}/lib/:$LD_LIBRARY_PATH"
export GI_TYPELIB_PATH="$DESTDIR/${PREFIX}/lib/:$GI_TYPELIB_PATH"
export PATH="$DESTDIR/${PREFIX}/bin:$PATH"
