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. You can also get metadata about the playing track such as the artist and title for integration into statusline generators or other command-line tools.
Playerctl also comes with a daemon that allows it to act on the currently active media player called playerctld.
playerctl [--version] [--list-all] [--all-players] [--player=NAME] [--ignore-player=IGNORE] [--format=FORMAT] [--no-messages] COMMAND
Here is a list of available commands:
| Command | Description |
|---|---|
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 or 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. Either "Playing", "Paused", or "Stopped". |
metadata [KEY...] |
Print the metadata for the current track. If KEY is passed, print only those values from the metadata. |
open [URI] |
Command for the player to open a given URI. Can be either a file path or a remote URL. |
loop [STATUS] |
Print or set the loop status. Either "None", "Track", or "Playlist". |
shuffle [STATUS] |
Print or set the shuffle status. Either "On", "Off". |
Without specifying any players to control, Playerctl will act on the first player it can find.
Playerctl comes with a service called playerctld that monitors the activity of media players in the background. If playerctld is running, Playerctl will act on players in order of their last activity. To start playerctld, add the following command to your system startup script:
playerctld daemon
You can list the names of players that are available to control that are running on the system with playerctl --list-all.
If you'd only like to control certain players, you can pass the names of those players separated by commas with the --player flag. Playerctl will select the first instance of a player in that list that supports the command. To control all players in the list, you can use the --all-players flag.
Similarly, you can ignore players by passing their names with the --ignore-player flag.
The special player name %any can be used in the list of selected players once to match any player not in the list. This can be used to prioritize or deprioritize players.
Examples:
# Command the first instance of VLC to play
playerctl --player=vlc play
# Command all players to stop
playerctl --all-players stop
# Command VLC to go to the next track if it's running. If it's not, send the
# command to Spotify.
playerctl --player=vlc,spotify next
# Get the status of the first player that is not Gwenview.
playerctl --ignore-player=Gwenview status
# Command any player to play, but select Chromium last
playerctl --player=%any,chromium play
# Command any player to play, but select VLC first
playerctl --player=vlc,%any playYou can pass a format string with the --format argument to print properties in a specific format. Pass the variable you want to print in the format string between double braces like {{ VARIABLE }}. The variables available are either the name of the query command, or anything in the metadata map which can be viewed with playerctl metadata. You can use this to integrate playerctl into a statusline generator.
For a simple "now playing" banner:
playerctl metadata --format "Now playing: {{ artist }} - {{ album }} - {{ title }}"
# prints 'Now playing: Lana Del Rey - Born To Die - Video Games'Included in the template language are some built-in variables and helper functions for common formatting that you can call on template variables. It can also do basic math operations on numbers.
# Prints 'Total length: 3:23'
playerctl metadata --format "Total length: {{ duration(mpris:length) }}"
# Prints 'At position: 1:16'
playerctl position --format "At position: {{ duration(position) }}"
# Prints 'Artist in lowercase: lana del rey'
playerctl metadata --format "Artist in lowercase: {{ lc(artist) }}"
# Prints 'STATUS: PLAYING'
playerctl status --format "STATUS: {{ uc(status) }}"
# Prints the time remaining in the track (e.g, 'Time remaining: 2:07')
playerctl metadata --format "Time remaining: {{ duration(mpris:length - position) }}"
# Prints volume from 0 - 100
playerctl metadata --format "Volume: {{ volume * 100 }}"| Function | Argument | Description |
|---|---|---|
lc |
string | Convert the string to lowercase. |
uc |
string | Convert the string to uppercase. |
duration |
int | Convert the duration to hh:mm:ss format. |
markup_escape |
string | Escape XML markup characters in the string. |
default |
any, any | Print the first value if it is present, or else print the second. |
emoji |
status or volume | Try to convert the variable to an emoji representation. |
trunc |
string, int | Truncate string to a maximum length. |
| Variable | Description |
|---|---|
playerName |
The name of the current player. |
position |
The position of the current track in microseconds |
status |
The playback status of the current player |
volume |
The volume from 0.0 to 1.0 |
album |
The album of the current track. |
artist |
The artist of the current track. |
title |
The title of the current track. |
You can pass the --follow flag to query commands to block, wait for players to connect, and print the query whenever it changes. If players are passed with --player, players earlier in the list will be preferred in the order they appear unless --all-players is passed. When no player can support the query, such as when all the players exit, a newline will be printed. For example, to be notified of information about the latest currently playing track for your media players, use:
playerctl metadata --format '{{ playerName }}: {{ artist }} - {{ title }} {{ duration(position) }}|{{ duration(mpris:length) }}' --followYou can seek to a position in the track or skip forward and back.
# Go back 30 seconds
playerctl position 30-
# Go forward 30 seconds
playerctl position 30+
# Seek to the position at 30 seconds
playerctl position 30To enable debug logging, set the environment variable G_MESSAGES_DEBUG=playerctl. It's helpful to include a debug log when you report issues.
Some players like Spotify require certain DBus environment variables to be set which are normally set within the session manager. If you're not using a session manager or it does not set these variables automatically (like xinit), launch your desktop environment wrapped in a dbus-launch command. For example, in your .xinitrc file, use this to start your WM:
exec dbus-launch --autolaunch=$(cat /var/lib/dbus/machine-id) i3
Some players may require installation of a plugin or other configuration.
In Quod Libet open the window File -> Plugins and select the plugin called MPRIS D-Bus Support.
If playerctld does not autostart and you use xinit and systemd, you might need this fix to enable DBus activation to work correctly:
systemctl --user import-environment DISPLAY XAUTHORITY
if which dbus-update-activation-environment >/dev/null 2>&1; then
dbus-update-activation-environment DISPLAY XAUTHORITY
fi
First, check and see if Playerctl 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.
playerctl is available for Fedora 28 or later:
sudo dnf install playerctl
playerctl is available for Mageia and openSUSE via this COPR repository. First, install the repository file for your distribution from COPR. Then, install playerctl with your package manager of choice.
playerctl is available as a Guix package which can be installed on any Linux distribution after installing Guix:
guix install playerctl
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 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"
To use a scripting library, find your favorite language from this list and install the bindings library. Documentation for the library is hosted here. For examples on how to use the library, see the examples folder.
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. This example uses the Python bindings.
#!/usr/bin/env python3
from gi.repository import Playerctl, GLib
player = Playerctl.Player('vlc')
def on_metadata(player, metadata):
if 'xesam:artist' in metadata.keys() and 'xesam:title' in metadata.keys():
print('Now playing:')
print('{artist} - {title}'.format(
artist=metadata['xesam:artist'][0], title=metadata['xesam:title']))
def on_play(player, status):
print('Playing at volume {}'.format(player.props.volume))
def on_pause(player, status):
print('Paused the song: {}'.format(player.get_title()))
player.connect('playback-status::playing', on_play)
player.connect('playback-status::paused', on_pause)
player.connect('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()For a more complete example which is capable of listening to when players start and exit, see player-manager.py from the official examples.
