  <title>The Music Player Daemon - User's Manual</title>

  <chapter>
    <title>Introduction</title>

    <para>
      This document is work in progress.  Most of it may be incomplete
      yet.  Please help!
    </para>

    <para>
      <application>MPD</application> (Music Player Daemon) is, as the
      name suggests, a server software allowing you to remotely play
      your music, handle playlists, deliver music (HTTP streams with
      various sub-protocols) and organizze playlists.
    </para>

    <para>
      It has been written with minimal resource usage and stability in
      mind!  Infact, it runs fine on a Pentium 75, allowing you to use
      your cheap old PC to create a stereo system!
    </para>

    <para>
      <application>MPD</application> supports also gapless playback,
      buffered audio output, and crossfading!
    </para>

    <para>
      The separate client and server design allows users to choose a
      user interface that best suites their tastes independently of
      the underlying daemon, which actually plays music!
    </para>
  </chapter>

  <chapter>
    <title>Installation</title>

    <para>
      We recommend that you use the software installation routines of
      your distribution to install <application>MPD</application>.
      Most operating systems have a <application>MPD</application>
      package, which is very easy to install.
    </para>

    <section>
      <title>Installing on Debian/Ubuntu</title>

      <para>
        Install the package <application>MPD</application> via APT:
      </para>

      <programlisting>apt-get install mpd</programlisting>

      <para>
        When installed this way, <application>MPD</application> by
        default looks for music in
        <filename>/var/lib/mpd/music/</filename>; this may not be
        correct. Look at your <filename>/etc/mpd.conf</filename>
        file...
      </para>
    </section>

    <section>
      <title>Compiling from source</title>

      <para>
        Download the source tarball from <ulink
        url="http://www.musicpd.org/download.html">the
        <application>MPD</application> home page</ulink> and unpack
        it:
      </para>

      <programlisting>tar xf mpd-version.tar.xz
cd mpd-version</programlisting>

      <para>
        Make sure that all the required libraries and build tools are
        installed.  The <filename>INSTALL</filename> file has a list.
      </para>

      <para>
        For example, the following installs a fairly complete list of
        build dependencies on Debian Wheezy:
      </para>

      <programlisting>
apt-get install g++ automake autoconf \
  libmad0-dev libmpg123-dev libid3tag0-dev \
  libflac-dev libvorbis-dev libopus-dev \

  libsystemd-daemon-dev libwrap0-dev \
  libcppunit-dev xmlto \
  libboost-dev \
  libglib2.0-dev
      </programlisting>

      <para>
        Now configure the source tree:
      </para>

      <programlisting>./configure</programlisting>

      <para>
        The <parameter>--help</parameter> argument shows a list of
        compile-time options.  When everything is ready and
        configured, compile:
      </para>

      <programlisting>make</programlisting>

      <para>
        And install:
      </para>

      <programlisting>make install</programlisting>
    </section>

    <section>
      <title><filename>systemd</filename> socket activation</title>

      <para>
        Using <filename>systemd</filename>, you can launch
        <application>MPD</application> on demand when the first client
        attempts to connect.
      </para>

      <para>
        <application>MPD</application> comes with two
        <application>systemd</application> unit files: a "service"
        unit and a "socket" unit.  These will only be installed when
        <application>MPD</application> was configured with
        <parameter>--with-systemdsystemunitdir=/lib/systemd</parameter>.
      </para>

      <para>
        To enable socket activation, type:
      </para>

      <programlisting>systemctl enable mpd.socket
systemctl start mpd.socket</programlisting>

      <para>
        In this configuration, <application>MPD</application> will
        ignore the <varname>bind_to_address</varname> and
        <varname>port</varname> settings.
      </para>
    </section>
  </chapter>

  <chapter>
    <title>Configuration</title>

    <section>
      <title>Configuring the music directory</title>

      <para>
        When you play local files, you should organize them within a
        directory called the "music directory".  This is configured in
        <application>MPD</application> with the
        <varname>music_directory</varname> setting.
      </para>

      <para>
        By default, <application>MPD</application> follows symbolic
        links in the music directory.  This behavior can be switched
        off: <varname>follow_outside_symlinks</varname> controls
        whether <application>MPD</application> follows links pointing
        to files outside of the music directory, and
        <varname>follow_inside_symlinks</varname> lets you disable
        symlinks to files inside the music directory.
      </para>

      <para>
        Instead of using local files, you can use storage plugins to
        access files on a remote file server.  For example, to use
        music from the SMB/CIFS server "myfileserver" on the share
        called "Music", configure the music directory
        "<parameter>smb://myfileserver/Music</parameter>".
      </para>
    </section>

    <section>
      <title>Configuring database plugins</title>

      <para>
        If a music directory is configured, one database plugin is
        used.  To configure this plugin, add a
        <varname>database</varname> block to
        <filename>mpd.conf</filename>:
      </para>

      <programlisting>database {
    plugin "simple"
    path "/var/lib/mpd/db"
}
      </programlisting>

      <para>
        The following table lists the <varname>database</varname>
        options valid for all plugins:
      </para>

      <informaltable>
        <tgroup cols="2">

    <section>
      <title>Configuring input plugins</title>

      <para>
        To configure an input plugin, add a <varname>input</varname>
        block to <filename>mpd.conf</filename>:
      </para>

      <programlisting>input {
    plugin "despotify"

              <entry>
                Allows you to disable a input plugin without
                recompiling.  By default, all plugins are enabled.

    <section>
      <title>Configuring decoder plugins</title>

      <para>
        Most decoder plugins do not need any special configuration.
        To configure a decoder, add a <varname>decoder</varname> block
        to <filename>mpd.conf</filename>:
      </para>

      <programlisting>decoder {

        Encoders are used by some of the output plugins (such as

      <title>Configuring audio outputs</title>

      <para>
        Audio outputs are devices which actually play the audio chunks
        produced by <application>MPD</application>.  You can configure
        any number of audio output devices, but there must be at least
        one.  If none is configured, <application>MPD</application>
        attempts to auto-detect.  Usually, this works quite well with
        ALSA, OSS and on Mac OS X.
      </para>

      <para>
        To configure an audio output manually, add an
        <varname>audio_output</varname> block to

        <title>Resampler</title>

        <para>
          Sometimes, music needs to be resampled before it can be
          played; for example, CDs use a sample rate of 44,100 Hz
          while many cheap audio chips can only handle 48,000 Hz.
          Resampling reduces the quality and consumes a lot of CPU.
          There are different options, some of them optimized for high
          quality and others for low CPU usage, but you can't have
          both at the same time.  Often, the resampler is the
          component that is responsible for most of
          <application>MPD</application>'s CPU usage.  Since
          <application>MPD</application> comes with high quality
          defaults, it may appear that <application>MPD</application>
          consumes more CPU than other software.

      <title>The client</title>

      <para>
        After you have installed, configured and started
        <application>MPD</application>, you choose a client to control
        the playback.
      </para>

      <para>
        The most basic client is <filename>mpc</filename>, which
        provides a command line interface.  It is useful in shell
        scripts.  Many people bind specific <filename>mpc</filename>
        commands to hotkeys.
      </para>

      <para>
        The <ulink
        url="http://www.musicpd.org/clients/"><application>MPD</application>
        Wiki</ulink> contains an extensive list of clients to choose
        from.

    <section>
      <title>The music directory and the database</title>

      <para>
        The "music directory" is where you store your music files.
        <application>MPD</application> stores all relevant meta
        information about all songs in its "database".  Whenever you
        add, modify or remove songs in the music directory, you have
        to update the database, for example with
        <filename>mpc</filename>:
      </para>

      <programlisting>mpc update</programlisting>

      <para>
        Depending on the size of your music collection and the speed
        of the storage, this can take a while.
      </para>

      <para>
        To exclude a file from the update, create a file called
        <filename>.mpdignore</filename> in its parent directory.  Each
        line of that file may contain a list of shell wildcards.
      </para>
    </section>

    <section>
      <title>The queue</title>

      <para>
        The queue (sometimes called "current playlist") is a list of
        songs to be played by <application>MPD</application>.  To play
        a song, add it to the queue and start playback.  Most clients
        offer an interface to edit the queue.

          Plays <ulink url="http://www.spotify.com">Spotify</ulink> tracks using the despotify
          library. The despotify plugin uses a <filename>spt://</filename> URI and a Spotify
          URL. So for example, you can add a song with:
        </para>
        
        <para>
          <filename>mpc add spt://spotify:track:5qENVY0YEdZ7fiuOax70x1</filename>
        </para>
        
        <para>
          You need a Spotify premium account to use this plugin, and you need
          to setup username and password in the configuration file. The
          configuration settings are global since the despotify playlist plugin
          use the same settings.

        <para>
          Allows <application>MPD</application> to access files on
          NFSv3 servers without actually mounting them (i.e. in
          userspace, without help from the kernel's VFS layer).  All
          URIs with the <filename>nfs://</filename> scheme are used
          according to <ulink
          url="http://tools.ietf.org/html/rfc2224">RFC2224</ulink>.
          Example:
        </para>

        <para>
          <filename>mpc add nfs://servername/path/filename.ogg</filename>
        </para>

        <para>
          Note that this usually requires enabling the "insecure" flag
          in the server's <filename>/etc/exports</filename> file,
          because <application>MPD</application> cannot bind to
          so-called "privileged" ports.  Don't fear: this will not
          make your file server insecure; the flag was named in a time
          long ago when privileged ports were thought to be meaningful
          for security.  By today's standards, NFSv3 is not secure at
          all, and if you believe it is, you're already doomed.

                  Must be an absolute path.  If the path does not
                  exist, it will be created when
                  <application>MPD</application> is started, and
                  removed when <application>MPD</application> is
                  stopped.  The FIFO will be created with the same
                  user and group as <application>MPD</application> is
                  running as.  Default permissions can be modified by
                  using the builtin shell command
                  <filename>umask</filename>.  If a FIFO already
                  exists at the specified path it will be reused, and
                  will not be removed when
                  <application>MPD</application> is stopped.  You can
                  use the "mkfifo" command to create this, and then
                  you may modify the permissions to your liking.
