# Configuration

Mopidy has a lot of config values you can tweak, but you only need to change a few to get up and running. A complete `~/.config/mopidy/mopidy.conf` may be as simple as this:

    [mpd]
    hostname = ::

    [spotify]
    username = alice
    password = mysecret

Mopidy primarily reads config from the file `~/.config/mopidy/mopidy.conf`, where `~` means your home directory. If your username is `alice` and you are running Linux, the config file should probably be at `/home/alice/.config/mopidy/mopidy.conf`. You can either create the configuration file yourself, or run the `mopidy` command, and it will create an empty config file for you and print what config values must be set to successfully start Mopidy.

When you have created the configuration file, open it in a text editor, and add the config values you want to change. If you want to keep the default for a config value, you should not add it to the config file, but leave it out so that when we change the default value in a future version, you won’t have to change your configuration accordingly.

To see what’s the effective configuration for your Mopidy installation, you can run:

    mopidy config

This will print your full effective config with passwords masked out so that you safely can share the output with others for debugging.

You can find a description of all config values belonging to Mopidy’s core below, together with their default values. In addition, all extensions got additional config values. The extension’s config values and config defaults are documented on the extension pages.

## Default core configuration

    [logging]
    color = true
    console_format = %(levelname)-8s %(message)s
    debug_format = %(levelname)-8s %(asctime)s [%(process)d:%(threadName)s] %(name)s\n  %(message)s
    debug_file = mopidy.log
    config_file =

    [audio]
    mixer = software
    mixer_volume =
    output = autoaudiosink

    [proxy]
    scheme =
    hostname =
    port =
    username =
    password =

## Core configuration values

Mopidy’s core has the following configuration values that you can change.

### Audio configuration

`audio/mixer`

  Audio mixer to use.

  The default is `software`, which does volume control inside Mopidy before the audio is sent to the audio output. This mixer does not affect the volume of any other audio playback on the system. It is the only mixer that will affect the audio volume if you’re streaming the audio from Mopidy through Shoutcast.

  If you want to disable audio mixing set the value to `none`.

  If you want to use a hardware mixer, you need to install a Mopidy extension which integrates with your sound subsystem. E.g. for ALSA, install Mopidy-ALSAMixer.

`audio/mixer_volume`

  Initial volume for the audio mixer.

  Expects an integer between 0 and 100.

  Setting the config value to blank leaves the audio mixer volume unchanged. For the software mixer blank means 100.

`audio/output`

  Audio output to use.

  Expects a GStreamer sink. Typical values are `autoaudiosink`, `alsasink`, `osssink`, `oss4sink`, `pulsesink`, and `shout2send`, and additional arguments specific to each sink. You can use the command `gst-inspect-0.10` to see what output properties can be set on the sink. For example: `gst-inspect-0.10 shout2send`

### Logging configuration

`logging/color`

  Whether or not to colorize the console log based on log level. Defaults to `true`.

`logging/console_format`

  The log format used for informational logging.

  See the Python logging docs for details on the format.

`logging/debug_format`

  The log format used for debug logging.

  See the Python logging docs for details on the format.

`logging/debug_file`

  The file to dump debug log data to when Mopidy is run with the mopidy --save-debug-log option.

`logging/config_file`

  Config file that overrides all logging config values, see the Python logging docs for details.

`loglevels/*`

  The `loglevels` config section can be used to change the log level for specific parts of Mopidy during development or debugging. Each key in the config section should match the name of a logger. The value is the log level to use for that logger, one of `debug`, `info`, `warning`, `error`, or `critical`.

`logcolors/*`

  The `logcolors` config section can be used to change the log color for specific parts of Mopidy during development or debugging. Each key in the config section should match the name of a logger. The value is the color to use for that logger, one of `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan` or `white`.

### Proxy configuration

Not all parts of Mopidy or all Mopidy extensions respect the proxy server configuration when connecting to the Internt. Currently, this is at least used when Mopidy’s audio subsystem reads media directly from the network, like when listening to Internet radio streams, and by the Mopidy-Spotify extension. With time, we hope that more of the Mopidy ecosystem will respect these configurations to help users on locked down networks.

`proxy/scheme`

  URI scheme for the proxy server. Typically `http`, `https`, `socks4`, or `socks5`.

`proxy/hostname`

  Hostname of the proxy server.

`proxy/port`

  Port number of the proxy server.

`proxy/username`

  Username for the proxy server, if needed.

`proxy/password`

  Password for the proxy server, if needed.

## Extension configuration

Mopidy’s extensions have their own config values that you may want to tweak. For the available config values, please refer to the docs for each extension. Most, if not all, can be found at Extensions.

Mopidy extensions are enabled by default when they are installed. If you want to disable an extension without uninstalling it, all extensions support the `enabled` config value even if it isn’t explicitly documented by all extensions. If the `enabled` config value is set to `false` the extension will not be started. For example, to disable the Spotify extension, add the following to your `mopidy.conf`:

    [spotify]
    enabled = false

## Advanced configurations

### Custom audio sink

If you have successfully installed GStreamer, and then run the `gst-inspect` or `gst-inspect-0.10` command, you should see a long listing of installed plugins, ending in a summary line:

    $ gst-inspect-0.10
    ... long list of installed plugins ...
    Total count: 254 plugins (1 blacklist entry not shown), 1156 features

Next, you should be able to produce a audible tone by running:

    gst-launch-0.10 audiotestsrc ! audioresample ! autoaudiosink

If you cannot hear any sound when running this command, you won’t hear any sound from Mopidy either, as Mopidy by default uses GStreamer’s `autoaudiosink` to play audio. Thus, make this work before you file a bug against Mopidy.

If you for some reason want to use some other GStreamer audio sink than `autoaudiosink`, you can set the `audio/output` config value to a partial GStreamer pipeline description describing the GStreamer sink you want to use.

Example `mopidy.conf` for using OSS4:

    [audio]
    output = oss4sink

Again, this is the equivalent of the following `gst-inspect` command, so make this work first:

    gst-launch-0.10 audiotestsrc ! audioresample ! oss4sink

### Streaming through SHOUTcast/Icecast

Warning

Known issue

Currently, Mopidy does not handle end-of-track vs end-of-stream signalling in GStreamer correctly. This causes the SHOUTcast stream to be disconnected at the end of each track, rendering it quite useless. For further details, see #492. You can also try the workaround mentioned below.

If you want to play the audio on another computer than the one running Mopidy, you can stream the audio from Mopidy through an SHOUTcast or Icecast audio streaming server. Multiple media players can then be connected to the streaming server simultaneously. To use the SHOUTcast output, do the following:

1. Install, configure and start the Icecast server. It can be found in the `icecast2` package in Debian/Ubuntu.

2. Set the `audio/output` config value to `lame ! shout2send`. An Ogg Vorbis encoder could be used instead of the lame MP3 encoder.

3. You might also need to change the `shout2send` default settings, run `gst-inspect-0.10 shout2send` to see the available settings. Most likely you want to change `ip`, `username`, `password`, and `mount`.

   Example for MP3 streaming:

       [audio]
       output = lame ! shout2send mount=mopidy ip=127.0.0.1 port=8000 password=hackme

   Example for Ogg Vorbis streaming:

       [audio]
       output = audioresample ! audioconvert ! vorbisenc ! oggmux ! shout2send mount=mopidy ip=127.0.0.1 port=8000 password=hackme

Other advanced setups are also possible for outputs. Basically, anything you can use with the `gst-launch-0.10` command can be plugged into `audio/output`.

Workaround for end-of-track issues - fallback streams

By using a fallback stream playing silence, you can somewhat mitigate the signalling issues.

Example Icecast configuration:

    <mount>
      <mount-name>/mopidy</mount-name>
      <fallback-mount>/silence.mp3</fallback-mount>
      <fallback-override>1</fallback-override>
    </mount>

The `silence.mp3` file needs to be placed in the directory defined by `<webroot>...</webroot>`.

### New configuration values

Mopidy’s config validator will stop you from defining any config values in your config file that Mopidy doesn’t know about. This may sound obnoxious, but it helps us detect typos in your config, and deprecated config values that should be removed or updated.

If you’re extending Mopidy, and want to use Mopidy’s configuration system, you can add new sections to the config without triggering the config validator. We recommend that you choose a good and unique name for the config section so that multiple extensions to Mopidy can be used at the same time without any danger of naming collisions.
