Max Kellermann 11bcd7f013 curl: moved proxy settings to "input" block
The old global settings "http_proxy_host", "http_proxy_port",
"http_proxy_user" and "http_proxy_password" continue to work.

<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>:
</para>
<programlisting>apt-get install mpd</programlisting>
</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-0.14.2.tar.bz
cd mpd-0.14.2</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>

<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:

<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 {
plugin "wildmidi"
config_file "/etc/timidity/timidity.cfg"
}

<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>
options valid for all plugins:

plugins.

Sets the device which should be used. This can be
any valid ALSA device name. The default value is
"default", which makes
<filename>libasound</filename> choose a device. It
is recommended to use a "hw" or "plughw" device,
because otherwise, <filename>libasound</filename>
automatically enables "dmix", which has major

It is recommended to let MPD resample (with

so.

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.
