<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!
</para>
</chapter>
<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>

The following table lists the <varname>input</varname> options

<title>Configuring decoder plugins</title>

Most decoder plugins do not need any special configuration.
To configure a decoder, add a <varname>decoder</varname> block

<programlisting>decoder {
plugin "wildmidi"
config_file "/etc/timidity/timidity.cfg"

<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
in the <varname>audio_output</varname> section.
</para>
</section>
<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 {
type "alsa"
name "my ALSA device"
device "hw:0"
}
</programlisting>
<para>
The following table lists the <varname>audio_output</varname>

Any of the three attributes may be an asterisk to
specify that this attribute should not be enforced,

<title>Using MPD</title>
<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.
</para>
</section>
<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.

<para>
<filename>mpc add spt://spotify:track:5qENVY0YEdZ7fiuOax70x1</filename>

<para>
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>
<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.
