Plugin reference
Database plugins
simple
The default plugin. Stores a copy of the database in memory. A file is used for permanent storage.
Setting |
Description |
---|---|
path |
The path of the database file. |
cache_directory |
The path of the cache directory for additional storages mounted at runtime. This setting is necessary for the mount protocol command. |
compress yes|no |
Compress the database file using gzip? Enabled by default (if built with zlib). |
hide_playlist_targets yes|no |
Hide songs which are referenced by playlists? Thas is,
playlist files which are represented in the database as virtual
directories (playlist plugin setting |
proxy
Provides access to the database of another MPD instance using libmpdclient. This is useful when you mount the music directory via NFS/SMB, and the file server already runs a MPD (0.20 or newer) instance. Only the file server needs to update the database.
Setting |
Description |
---|---|
host |
The host name of the “master” MPD instance. |
port |
The port number of the “master” MPD instance. |
password |
The password used to log in to the “master” MPD instance. |
keepalive yes|no |
Send TCP keepalive packets to the “master” MPD instance? This option can help avoid certain firewalls dropping inactive connections, at the expense of a very small amount of additional network traffic. Disabled by default. |
upnp
Provides access to UPnP media servers.
Setting |
Description |
---|---|
interface |
Interface used to discover media servers. Decided by upnp if left unconfigured. |
Storage plugins
local
The default plugin which gives MPD access to local files. It is used when music_directory refers to a local directory.
curl
A WebDAV client using libcurl. It is used when music_directory
contains a http://
or https://
URI, for example
https://the.server/dav/
.
smbclient
Load music files from a SMB/CIFS server. It is used when
music_directory
contains a smb://
URI, for example
smb://myfileserver/Music
.
Note that libsmbclient
has a serious bug which causes MPD to
crash, and therefore this plugin is disabled by default and should not
be used until the bug is fixed:
https://bugzilla.samba.org/show_bug.cgi?id=11413
nfs
Load music files from a NFS server. It is used when
music_directory
contains a nfs://
URI according to
RFC2224, for example nfs://servername/path
.
See nfs for more information.
udisks
Mount file systems (e.g. USB sticks or other removable media) using the udisks2 daemon via D-Bus. To obtain a valid udisks2 URI, consult the according neighbor plugin.
It might be necessary to grant MPD privileges to control
udisks2 through policykit. To do this, create a
file called /usr/share/polkit-1/rules.d/mpd-udisks.rules
with
the following text:
polkit.addRule(function(action, subject) {
if ((action.id == "org.freedesktop.udisks2.filesystem-mount" ||
action.id == "org.freedesktop.udisks2.filesystem-mount-other-seat") &&
subject.user == "mpd") {
return polkit.Result.YES;
}
});
If you run MPD as a different user, change mpd
to the name of your
MPD user.
Neighbor plugins
smbclient
Provides a list of SMB/CIFS servers on the local network.
udisks
Queries the udisks2 daemon via D-Bus and obtains a list of file systems (e.g. USB sticks or other removable media).
upnp
Provides a list of UPnP servers on the local network.
Input plugins
alsa
Allows MPD on Linux to play audio directly from a soundcard using the scheme alsa://. Audio is by default formatted as 48 kHz 16-bit stereo, but this default can be overidden by a config file setting or by the URI. Examples:
mpc add alsa:// plays audio from device default
mpc add alsa://hw:1,0 plays audio from device hw:1,0
mpc add alsa://hw:1,0?format=44100:16:2 plays audio from device hw:1,0 sampling 16-bit stereo at 44.1kHz.
Setting |
Description |
---|---|
default_device NAME |
The alsa device id to use when none is specified in the URI. |
default_format F |
The sampling rate, size and channels to use. Wildcards are not allowed. Example - “44100:16:2” |
auto_resample yes|no |
If set to no, then libasound will not attempt to resample. In this case, the user is responsible for ensuring that the requested sample rate can be produced natively by the device, otherwise an error will occur. |
auto_channels yes|no |
If set to no, then libasound will not attempt to convert between different channel numbers. The user must ensure that the device supports the requested channels when sampling. |
auto_format yes|no |
If set to no, then libasound will not attempt to convert between different sample formats (16 bit, 24 bit, floating point, …). Again the user must ensure that the requested format is available natively from the device. |
cdio_paranoia
Plays audio CDs using libcdio. The URI has the form: “cdda://[DEVICE][/TRACK]”. The simplest form cdda:// plays the whole disc in the default drive.
Setting |
Description |
---|---|
default_byte_order little_endian|big_endian |
If the CD drive does not specify a byte order, MPD assumes it is the CPU’s native byte order. This setting allows overriding this. |
speed N |
Request CDParanoia cap the extraction speed to Nx normal CD audio rotation speed, keeping the drive quiet. |
mode disable|overlap|full |
Set the paranoia mode; |
skip yes|no |
If set to |

Set the onoff parameter to 1 to make the library display a lot of verbose information. More information. |
no |
low_speed_limit [1] |
The average transfer speed in bytes per second that the transfer should be below during low_speed_time seconds for libcurl to consider it to be too slow and abort. More information. |
0 (disabled) |
low_speed_time [1] |
The time in number seconds that the transfer speed should be below the low_speed_limit for the libcurl to consider it too slow and abort. More information. |
0 (disabled) |
tcp_keepalive yes|no [1] |
If set to yes, TCP keepalive probes will be sent. The delay and frequency of these probes can be controlled by the tcp_keepidle and tcp_keepintvl options, provided the operating system supports them. More information. |
no (disabled) |
tcp_keepidle [1] |
Sets the delay, in seconds, that the operating system will wait while the connection is idle before sending keepalive probes. Not all operating systems support this option. More information. |
60 |
tcp_keepintvl [1] |
Sets the interval, in seconds, that the operating system will wait between sending keepalive probes. Not all operating systems support this option. More information. |
60 |
Note: the low_speed
and tcp_keep
options may help solve network interruptions and connections dropped by server. Please refer to this curl issue for discussion: https://github.com/curl/curl/issues/8345
ffmpeg
Access to various network protocols implemented by the FFmpeg library:
gopher://
, rtp://
, rtsp://
, rtmp://
, rtmpt://
,
rtmps://
file
Opens local files
mms
Plays streams with the MMS protocol using libmms.
nfs
Allows MPD to access files on NFS servers without actually
mounting them (i.e. with libnfs in userspace, without help
from the kernel’s VFS layer). All URIs with the nfs://
scheme are
used according to RFC2224. Example:
mpc add nfs://servername/path/filename.ogg
This plugin uses libnfs, which supports only NFS version 3.
Since MPD is not allowed to bind to so-called “privileged
ports”, the NFS server needs to enable the insecure
setting;
example /etc/exports
:
/srv/mp3 192.168.1.55(ro,insecure)
Don’t fear: this will not make your file server insecure; the flag was named 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.
smbclient
Allows MPD to access files on SMB/CIFS servers (e.g. Samba
or Microsoft Windows). All URIs with the smb://
scheme are
used. Example:
mpc add smb://servername/sharename/filename.ogg
mpc add smb://username:password@servername/sharename/filename.ogg

Output plugins
alsa
The Advanced Linux Sound Architecture (ALSA) plugin uses libasound. It is recommended if you are using Linux.
Setting |
Description |
---|---|
device NAME |
Sets the device which should be used. This can be any valid ALSA device name. The default value is “default”, which makes libasound choose a device. It is recommended to use a “hw” or “plughw” device, because otherwise, libasound automatically enables “dmix”, which has major disadvantages (fixed sample rate, poor resampler, …). |
buffer_time US |
Sets the device’s buffer time in microseconds. Don’t change unless you know what you’re doing. |
period_time US |
Sets the device’s period time in microseconds. Don’t change unless you really know what you’re doing. |
auto_resample yes|no |
If set to no, then libasound will not attempt to resample, handing the responsibility over to MPD. It is recommended to let MPD resample (with libsamplerate), because ALSA is quite poor at doing so. |
auto_channels yes|no |
If set to no, then libasound will not attempt to convert between different channel numbers. |
auto_format yes|no |
If set to no, then libasound will not attempt to convert between different sample formats (16 bit, 24 bit, floating point, …). |
dop yes|no |
If set to yes, then DSD over PCM according to the DoP standard is enabled. This wraps DSD samples in fake 24 bit PCM, and is understood by some DSD capable products, but may be harmful to other hardware. Therefore, the default is no and you can enable the option at your own risk. |
stop_dsd_silence yes|no |
If enabled, silence is played before manually stopping playback (“stop” or “pause”) in DSD mode (native DSD or DoP). This is a workaround for some DACs which emit noise when stopping DSD playback. |
thesycon_dsd_workaround yes|no |
If enabled, enables a workaround for a bug in Thesycon USB audio receivers. On these devices, playing DSD512 or PCM causes all subsequent attempts to play other DSD rates to fail, which can be fixed by briefly playing PCM at 44.1 kHz. |
allowed_formats F1 F2 … |
Specifies a list of allowed audio formats, separated by a space. All items may contain asterisks as a wild card, and may be followed by “=dop” to enable DoP (DSD over PCM) for this particular format. The first matching format is used, and if none matches, MPD chooses the best fallback of this list. Example: “96000:16:* 192000:24:* dsd64:=dop *:dsd:”. |
The according hardware mixer plugin understands the following settings:
Setting |
Description |
---|---|
mixer_device DEVICE |
Sets the ALSA mixer device name, defaulting to default which lets ALSA pick a value. |
mixer_control NAME |
Choose a mixer control, defaulting to PCM. Type amixer scontrols to get a list of available mixer controls. |
mixer_index NUMBER |
Choose a mixer control index. This is necessary if there is more than one control with the same name. Defaults to 0 (the first one). |
The following attributes can be configured at runtime using the outputset command:
Setting |
Description |
---|---|
dop 1|0 |
Allows changing the dop configuration setting at runtime. This takes effect the next time the output is opened. |
allowed_formats F1 F2 … |
Allows changing the allowed_formats configuration setting at runtime. This takes effect the next time the output is opened. |
ao
The ao plugin uses the portable libao library. Use only if there is no native plugin for your operating system.
Setting |
Description |
---|---|
driver D |
The libao driver to use for audio output. Possible values depend on what libao drivers are available. See http://www.xiph.org/ao/doc/drivers.html for information on some commonly used drivers. Typical values for Linux include “oss” and “alsa09”. The default is “default”, which causes libao to select an appropriate plugin. |
options O |
Options to pass to the selected libao driver. |
write_size O |
This specifies how many bytes to write to the audio device at once. This parameter is to work around a bug in older versions of libao on sound cards with very small buffers. The default is 1024. |
sndio
The sndio plugin uses the sndio library. It should normally be used on OpenBSD.
Setting |
Description |
---|---|
device NAME |
The audio output device libsndio will attempt to use. The default is “default” which causes libsndio to select the first output device. |
buffer_time MS |
Set the application buffer time in milliseconds. |
fifo
The fifo plugin writes raw PCM data to a FIFO (First In, First Out) file. The data can be read by another program.
Setting |
Description |
---|---|
path P |
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. |
jack
The jack plugin connects to a JACK server.
On Windows, this plugin loads libjack64.dll
at runtime. This
means you need to download and install the JACK windows build.
Setting |
Description |
---|---|
client_name NAME |
The name of the JACK client. Defaults to “Music Player Daemon”. |
server_name NAME |
Optional name of the JACK server. |
autostart yes|no |
If set to yes, then libjack will automatically launch the JACK daemon. Disabled by default. |
source_ports A,B |
The names of the JACK source ports to be created. By default, the ports “left” and “right” are created. To use more ports, you have to tweak this option. |
destination_ports A,B |
The names of the JACK destination ports to connect to. |
auto_destination_ports yes|no |
If set to yes, then MPD will automatically create connections between the send ports of MPD and receive ports of the first sound card; if set to no, then MPD will only create connections to the contents of destination_ports if it is set. Enabled by default. |
ringbuffer_size NBYTES |
Sets the size of the ring buffer for each channel. Do not configure this value unless you know what you’re doing. |
httpd
The httpd plugin creates a HTTP server, similar to ShoutCast / IceCast. HTTP streaming clients like mplayer, VLC, and mpv can connect to it.
It is highly recommended to configure a fixed format, because a stream cannot switch its audio format on-the-fly when the song changes.
Setting |
Description |
---|---|
port P |
Binds the HTTP server to the specified port. |
bind_to_address ADDR |
Binds the HTTP server to the specified address (IPv4, IPv6 or local socket). Multiple addresses in parallel are not supported. |

---|---|
sync yes|no |
If set to no, then the timer is disabled - the device will accept PCM chunks at arbitrary rate (useful for benchmarking). The default behaviour is to play in real time. |
oss
The “Open Sound System” plugin is supported on most Unix platforms.
On Linux, OSS has been superseded by ALSA. Use the ALSA output plugin alsa instead of this one on Linux.
Setting |
Description |
---|---|
device PATH |
Sets the path of the PCM device. If not specified, then MPD will attempt to open /dev/sound/dsp and /dev/dsp. |
dop yes|no |
If set to yes, then DSD over PCM according to the DoP standard is enabled. This wraps DSD samples in fake 24 bit PCM, and is understood by some DSD capable products, but may be harmful to other hardware. Therefore, the default is no and you can enable the option at your own risk. |
The according hardware mixer plugin understands the following settings:
Setting |
Description |
---|---|
mixer_device DEVICE |
Sets the OSS mixer device path, defaulting to /dev/mixer. |
mixer_control NAME |
Choose a mixer control, defaulting to PCM. |
openal
The “OpenAL” plugin uses libopenal. It is supported on many platforms. Use only if there is no native plugin for your operating system.
Setting |
Description |
---|---|
device NAME |
Sets the device which should be used. This can be any valid OpenAL device name. If not specified, then libopenal will choose a default device. |
osx
The “Mac OS X” plugin uses Apple’s CoreAudio API.
Setting |
Description |
---|---|
device NAME |
Sets the device which should be used. Uses device names as listed in the “Audio Devices” window of “Audio MIDI Setup”. |
hog_device yes|no |
Hog the device. This means that it takes exclusive control of the audio output device it is playing through, and no other program can access it. |
dop yes|no |
If set to yes, then DSD over PCM according to the DoP standard is enabled. This wraps DSD samples in fake 24 bit PCM, and is understood by some DSD capable products, but may be harmful to other hardware. Therefore, the default is no and you can enable the option at your own risk. Under macOS you must make sure to select a physical mode on the output device which supports at least 24 bits per channel as the Mac OS X plugin only changes the sample rate. |
channel_map SOURCE,SOURCE,… |
Specifies a channel map. If your audio device has more than two outputs this allows you to route audio to auxillary outputs. For predictable results you should also specify a “format” with a fixed number of channels, e.g. “::2”. The number of items in the channel map must match the number of output channels of your output device. Each list entry specifies the source for that output channel; use “-1” to silence an output. For example, if you have a four-channel output device and you wish to send stereo sound (format “::2”) to outputs 3 and 4 while leaving outputs 1 and 2 silent then set the channel map to “-1,-1,0,1”. In this example ‘0’ and ‘1’ denote the left and right channel respectively. The channel map may not refer to outputs that do not exist according to the format. If the format is “::1” (mono) and you have a four-channel sound card then “-1,-1,0,0” (dual mono output on the second pair of sound card outputs) is a valid channel map but “-1,-1,0,1” is not because the second channel (‘1’) does not exist when the output is mono. |
pipe

format_path P |
An alternative to path which provides a format string referring to tag values. The special tag iso8601 emits the current date and time in ISO8601 format (UTC). Every time a new song starts or a new tag gets received from a radio station, a new file is opened. If the format does not render a file name, nothing is recorded. A tag name enclosed in percent signs (‘%’) is replaced with the tag value. Example: |
