Ubuntu Manpage: mpd.conf - Music Player Daemon configuration file

NAME

       mpd.conf - Music Player Daemon configuration file

DESCRIPTION

       mpd.conf  is the configuration file for mpd(1).  If not specified on the command line, MPD first searches
       for it  at  $XDG_CONFIG_HOME/mpd/mpd.conf  then  at  ~/.mpdconf  then  at  ~/.mpd/mpd.conf  and  then  in
       /etc/mpd.conf.

       Lines  beginning  with  a  "#"  character are comments.  All other non-empty lines specify parameters and
       their values.  These lines contain the parameter name and parameter value (surrounded by  double  quotes)
       separated by whitespace (either tabs or spaces).  For example:

       parameter "value"

       The exception to this rule is the audio_output parameter, which is of the form:

       audio_output {
               parameter1 "value"
               parameter2 "value"
       }

       Parameters that take a file or directory as an argument should use absolute paths.

       See docs/mpdconf.example in the source tarball for an example configuration file.

       This  manual  is not complete, it lists only the most important options.  Please read the MPD user manual
       for a complete configuration guide: <http://www.musicpd.org/doc/user/>

REQUIRED PARAMETERS

       db_file <file>
              This specifies where the db file will be stored.

       log_file <file>
              This specifies where the log file should be located.  The special value "syslog" makes MPD use the
              local syslog daemon.

OPTIONAL PARAMETERS

sticker_file <file>
The location of the sticker database. This is a database which manages dynamic information
attached to songs.

pid_file <file>
This specifies the file to save mpd's process ID in.

music_directory <directory>
This specifies the directory where music is located. If you do not configure this, you can only
play streams.

playlist_directory <directory>
This specifies the directory where saved playlists are stored. If you do not configure this, you
cannot save playlists.

state_file <file>
This specifies if a state file is used and where it is located. The state of mpd will be saved to
this file when mpd is terminated by a TERM signal or by the "kill" command. When mpd is
restarted, it will read the state file and restore the state of mpd (including the playlist).

restore_paused <yes or no>
Put MPD into pause mode instead of starting playback after startup.

user <username>
This specifies the user that MPD will run as, if set. MPD should never run as root, and you may
use this option to make MPD change its user id after initialization. Do not use this option if
you start MPD as an unprivileged user.

bind_to_address <ip address or hostname or any>
This specifies which address mpd binds to and listens on. Multiple bind_to_address parameters may
be specified. The default is "any", which binds to all available addresses.

You can set a port that is different from the global port setting, e.g. "localhost:6602". IPv6
addresses must be enclosed in square brackets if you want to configure a port, e.g. "[::1]:6602".

To bind to a Unix domain socket, specify an absolute path or a path starting with a tilde (~).
For a system-wide MPD, we suggest the path "/var/run/mpd/socket".

port <port>
This specifies the port that mpd listens on. The default is 6600.

log_level <default, secure, or verbose>
This specifies how verbose logs are. "default" is minimal logging, "secure" reports from what
address a connection is opened, and when it is closed, and "verbose" records excessive amounts of
information for debugging purposes. The default is "default".

follow_outside_symlinks <yes or no>
Control if MPD will follow symbolic links pointing outside the music dir. You must recreate the
database after changing this option. The default is "yes".

follow_inside_symlinks <yes or no>
Control if MPD will follow symbolic links pointing inside the music dir, potentially adding
duplicates to the database. You must recreate the database after changing this option. The
default is "yes".

zeroconf_enabled <yes or no>
If yes, and MPD has been compiled with support for Avahi or Bonjour, service information will be
published with Zeroconf. The default is yes.

zeroconf_name <name>
If Zeroconf is enabled, this is the service name to publish. This name should be unique to your
local network, but name collisions will be properly dealt with. The default is "Music Player".

password <password@permissions>
This specifies a password for access to mpd. The format is "password@permissions" where
permissions is a comma delimited list composed of "read", "add", "control", and/or "admin".
"read" allows for reading of the database, displaying the current playlist, and current status of
mpd. "add" allows for adding songs and loading playlists. "control" allows for all other player
and playlist manipulations. "admin" allows the db to be updated and for the client to kill mpd.
An example value is "somePassword@read,add". Multiple password parameters may be specified.

default_permissions <permissions>
This specifies the permissions of a client that has not been authenticated using a password. The
format of permissions is specified in the description of the "password" config parameter. If no
passwords are specified, the default is "read,add,control,admin", otherwise it is "" (no
permissions).

audio_output
See DESCRIPTION and the various AUDIO OUTPUT PARAMETERS sections for the format of this parameter.
Multiple audio_output sections may be specified. If no audio_output section is specified, then
MPD will scan for a usable audio output.

replaygain <off or album or track or auto>
If specified, mpd will adjust the volume of songs played using ReplayGain tags (see
<http://www.replaygain.org/>). Setting this to "album" will adjust volume using the album's
ReplayGain tags, while setting it to "track" will adjust it using the track ReplayGain tags.
"auto" uses the track ReplayGain tags if random play is activated otherwise the album ReplayGain
tags. Currently only FLAC, Ogg Vorbis, Musepack, and MP3 (through ID3v2 ReplayGain tags, not
APEv2) are supported.

replaygain_preamp <-15 to 15>
This is the gain (in dB) applied to songs with ReplayGain tags.

volume_normalization <yes or no>
If yes, mpd will normalize the volume of songs as they play. The default is no.

filesystem_charset <charset>
This specifies the character set used for the filesystem. A list of supported character sets can
be obtained by running "iconv -l". The default is determined from the locale when the db was
originally created.

gapless_mp3_playback <yes or no>
This specifies whether to support gapless playback of MP3s which have the necessary headers.
Useful if your MP3s have headers with incorrect information. If you have such MP3s, it is highly
recommended that you fix them using vbrfix (available from
<http://www.willwap.co.uk/Programs/vbrfix.php>) instead of disabling gapless MP3 playback. The
default is to support gapless MP3 playback.

save_absolute_paths_in_playlists <yes or no>
This specifies whether relative or absolute paths for song filenames are used when saving
playlists. The default is "no".

auto_update <yes or no>
This specifies the whether to support automatic update of music database when files are changed in
music_directory. The default is to disable autoupdate of database.

auto_update_depth <N>
Limit the depth of the directories being watched, 0 means only watch the music directory itself.
There is no limit by default.

REQUIRED AUDIO OUTPUT PARAMETERS

type <type>
This specifies the audio output type. See the list of supported outputs in mpd --version for
possible values.

name <name>
This specifies a unique name for the audio output.

OPTIONAL AUDIO OUTPUT PARAMETERS

       format <sample_rate:bits:channels>
              This specifies the sample rate, bits per sample, and number of channels of audio that is  sent  to
              the  audio  output  device.   See  documentation  for  the  audio_output_format parameter for more
              details.  The default is to use whatever audio format is passed to the audio output.  Any  of  the
              three attributes may be an asterisk to specify that this attribute should not be enforced

       replay_gain_handler <software, mixer or none>
              Specifies  how replay gain is applied.  The default is "software", which uses an internal software
              volume control.  "mixer" uses the configured (hardware) mixer  control.   "none"  disables  replay
              gain on this audio output.

OPTIONAL ALSA OUTPUT PARAMETERS

device <dev>
This specifies the device to use for audio output. The default is "default".

mixer_type <hardware, software or none>
Specifies which mixer should be used for this audio output: the hardware mixer (available for
ALSA, OSS and PulseAudio), the software mixer or no mixer ("none"). By default, the hardware
mixer is used for devices which support it, and none for the others.

mixer_device <mixer dev>
This specifies which mixer to use. The default is "default". To use the second sound card in a
system, use "hw:1".

mixer_control <mixer ctrl>
This specifies which mixer control to use (sometimes referred to as the "device"). The default is
"PCM". Use "amixer scontrols" to see the list of possible controls.

mixer_index <mixer index>
A number identifying the index of the named mixer control. This is probably only useful if your
alsa device has more than one identically-named mixer control. The default is "0". Use "amixer
scontrols" to see the list of controls with their indexes.

auto_resample <yes or no>
Setting this to "no" disables ALSA's software resampling, if the hardware does not support a
specific sample rate. This lets MPD do the resampling. "yes" is the default and allows ALSA to
resample.

auto_channels <yes or no>
Setting this to "no" disables ALSA's channel conversion, if the hardware does not support a
specific number of channels. Default: "yes".

auto_format <yes or no>
Setting this to "no" disables ALSA's sample format conversion, if the hardware does not support a
specific sample format. Default: "yes".

buffer_time <time in microseconds>
This sets the length of the hardware sample buffer in microseconds. Increasing it may help to
reduce or eliminate skipping on certain setups. Most users do not need to change this. The
default is 500000 microseconds (0.5 seconds).

period_time <time in microseconds>
This sets the time between hardware sample transfers in microseconds. Increasing this can reduce
CPU usage while lowering it can reduce underrun errors on bandwidth-limited devices. Some users
have reported good results with this set to 50000, but not all devices support values this high.
Most users do not need to change this. The default is 256000000 / sample_rate(kHz), or 5804
microseconds for CD-quality audio.
