Jukebox mode
============

The jukebox mode allow playing audio files on the hardware of the machine
running *Supysonic*, using regular clients that support it as a remote control.

The daemon must be running in order to be able to use the jukebox mode. So be
sure to start the ``supysonic-daemon`` command and keep it running. A basic
*systemd* service file can be found at the root of the project folder.

Setting the player program
--------------------------

Jukebox mode in *Supysonic* works through the use of third-party command-line
programs. *Supysonic* isn't bundled with such programs, and you are left to
choose which one you want to use. The chosen program should be able to play a
single audio file from a path specified on its command-line.

The configuration is done in the :ref:`conf-daemon` of the configuration file,
with the ``jukebox_command`` variable. This variable should include the
following fields:

``%path``
   absolute path of the file to be played
``%offset``
   time in seconds where to start playing (used for seeking)

Here's an example using ``mplayer``::

   jukebox_command = mplayer -ss %offset %path

Or using ``mpv``::

   jukebox_command = mpv --start=%offset %path

Setting the output volume isn't currently supported.

Allowing users to act on the jukebox
------------------------------------

The jukebox mode is only accessible to chosen users. Granting (or revoking)
jukebox usage rights to a specific user is done with the
:doc:`command line interface <man/supysonic-cli-user>`::

   $ supysonic-cli user setroles --jukebox <username>
