  <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://mpd.wikia.com/wiki/Server">the MPD home
        page</ulink> and unpack it:
      </para>

      <programlisting>tar xjf mpd-version.tar.bz
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>
        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>
  </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
        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>
    </section>

    <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 "lastfm"
    user "foo"
    password "bar"
}
      </programlisting>

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

      <informaltable>

      <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

      <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

                If set to "yes", then MPD attempts to keep this audio

                control.  "mixer" uses the configured (hardware) mixer
                control.  "none" disables replay gain on this audio

    <section>
      <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://mpd.wikia.com/wiki/Clients">MPD
        Wiki</ulink> contains an extensive list of clients to choose
        from.

      <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.

      <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.
