  <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>
      MPD (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>
      MPD 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!

  <chapter>
    <title>Installation</title>

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

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

      <para>
        Install the package <filename>mpd</filename> via APT:
      </para>

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

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

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

      <para>
        Download the source tarball from <ulink
        url="http://www.musicpd.org/download.html">the MPD 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 \

      </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
        <filename>mpd</filename> on demand when the first client
        attempts to connect.
      </para>

      <para>
        MPD comes with two <filename>systemd</filename> unit files: a
        "service" unit and a "socket" unit.  These will only be
        installed when MPD 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, <filename>mpd</filename> will ignore
        the <varname>bind_to_address</varname> and
        <varname>port</varname> settings.
      </para>
    </section>

  <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
        MPD with the <varname>music_directory</varname> setting.
      </para>

      <para>
        By default, MPD follows symbolic links in the music directory.
        This behavior can be switched off:
        <varname>follow_outside_symlinks</varname> controls whether
        MPD 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>

      <title>Configuring encoder plugins</title>

      <para>
        Encoders are used by some of the output plugins (such as
        <varname>shout</varname>).  The encoder settings are included

    <section>
      <title>Configuring audio outputs</title>

      <para>
        Audio outputs are devices which actually play the audio chunks
        produced by MPD.  You can configure any number of audio output
        devices, but there must be at least one.  If none is
        configured, MPD 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
        <filename>mpd.conf</filename>:
      </para>

      <programlisting>audio_output {

                The name of the audio output.  It is visible to the
                client.  Some plugins also use it internally, e.g. as

        <para>
          The setting <varname>audio_output_format</varname> forces
          MPD to use one audio format for all outputs.  Doing that is
          usually not a good idea.  The values are the same as in

        <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 MPD's CPU usage.
          Since MPD comes with high quality defaults, it may appear
          that MPD consumes more CPU than other software.

      <title>The client</title>

      <para>
        After you have installed, configured and started MPD, 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/">MPD
        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.
        MPD 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 MPD.  To play a song, add it to the
        queue and start playback.  Most clients offer an interface to
        edit the queue.

                  assumes it is the CPU's native byte order.  This
                  setting allows overriding this.

          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 MPD 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 MPD 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.

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

          The <varname>httpd</varname> plugin creates a HTTP server,
          similar to ShoutCast / IceCast.  HTTP streaming clients like
          <filename>mplayer</filename> can connect to it.

        <para>
          You must configure either <varname>quality</varname> or
          <varname>bitrate</varname>.  It is highly recommended to
          configure a fixed <varname>format</varname>, because a
          stream cannot switch its audio format on-the-fly when the
          song changes.
