MumbleDJ

A Mumble bot that plays audio fetched from various media websites.

Table of Contents

Features

  • Plays audio from many media websites, including YouTube, SoundCloud, and Mixcloud.
  • Supports playlists and individual videos/tracks.
  • Displays metadata in the text chat whenever a new track starts playing.
  • Incredibly customizable. Nearly everything is able to be tweaked via configuration files (by default located at $HOME/.config/mumbledj/config.yaml).
  • A large array of commands that perform a wide variety of functions.
  • Built-in vote-skipping.
  • Built-in caching system (disabled by default).
  • Built-in play/pause/volume control.

Installation

IMPORTANT NOTE: MumbleDJ is only tested and developed for Linux systems. Support will not be given for non-Linux systems if problems are encountered.

Requirements

All MumbleDJ installations must also have the following installed:

If installing via go install or from source, the following must be installed:

  • Go 1.5+
    • NOTE: Extra installation steps are required for a working Go installation. Once Go is installed, type go help gopath for more information.
    • If the repositories for your distro contain a version of Go older than 1.5, try using gvm to install Go 1.5 or newer.

YouTube API Key

A YouTube API key must be present in your configuration file in order to use the YouTube service within the bot. Below is a guide for retrieving an API key:

1) Navigate to the Google Developers Console and sign in with your Google account, or create one if you haven't already.

2) Click the "Create Project" button and give your project a name. It doesn't matter what you set your project name to. Once you have a name click the "Create" button. You should be redirected to your new project once it's ready.

3) Click on "APIs & auth" on the sidebar, and then click APIs. Under the "YouTube APIs" header, click "YouTube Data API". Click on the "Enable API" button.

4) Click on the "Credentials" option underneath "APIs & auth" on the sidebar. Underneath "Public API access" click on "Create New Key". Choose the "Server key" option.

5) Add the IP address of the machine MumbleDJ will run on in the box that appears (this is optional, but improves security). Click "Create".

6) You should now see that an API key has been generated. Copy/paste this API key into the configuration file located at $HOME/.config/mumbledj/mumbledj.yaml.

SoundCloud API Key

A SoundCloud client ID must be present in your configuration file in order to use the SoundCloud service within the bot. Below is a guide for retrieving a client ID:

1) Login/sign up for a SoundCloud account on https://soundcloud.com.

2) Create a new app: https://soundcloud.com/you/apps/new.

3) You should now see that a client ID has been generated. Copy/paste this ID (NOT the client secret) into the configuration file located at $HOME/.config/mumbledj/mumbledj.yaml.

Via go get (recommended)

After verifying that the requirements are installed, simply issue the following command:

go get -u github.com/matthieugrieger/mumbledj

This should place a binary in $GOPATH/bin that can be used to start the bot.

NOTE: If using Go 1.5, you MUST execute the following for go get to work:

export GO15VENDOREXPERIMENT=1

Pre-compiled Binaries (easiest)

Pre-compiled binaries are provided for convenience. Overall, I do not recommend using these unless you cannot get go install to work properly. Binaries compiled on your own machine are likely more efficient as these binaries are cross-compiled from a 64-bit Linux system.

After verifying that the requirements are installed, simply visit the releases page and download the appropriate binary for your platform.

From Source

First, clone the MumbleDJ repository to your machine:

git clone https://github.com/matthieugrieger/mumbledj.git

Install the required software as described in the requirements section, and execute the following:

make

This will place a compiled mumbledj binary in the cloned directory if successful. If you would like to make the binary more accessible by adding it to /usr/local/bin, simply execute the following:

sudo make install

Docker

You can also use Docker to run MumbleDJ.

First you need to clone the MumbleDJ repository to your machine:

git clone https://github.com/matthieugrieger/mumbledj.git

Assuming you have Docker installed, you will have to build the image:

docker build -t mumbledj .

And then you can run it, passing the configuration through the command line:

docker run --rm --name=mumbledj mumbledj --server=SERVER --api_keys.youtube=YOUR_YOUTUBE_API_KEY --api_keys.soundcloud=YOUR_SOUNDCLOUD_API_KEY

In order to run the process as a daemon and restart it automatically on reboot you can use:

docker run -d --restart=unless-stopped --name=mumbledj mumbledj --server=SERVER --api_keys.youtube=YOUR_YOUTUBE_API_KEY --api_keys.soundcloud=YOUR_SOUNDCLOUD_API_KEY

You can also install Docker on a Raspberry Pi for instance with hypriot or with archlinux. You just need to build the ARM image:

docker build -f raspberry.Dockerfile -t mumbledj .

Usage

MumbleDJ is a compiled program that is executed via a terminal.

Here is an example helptext that gives you a feel for the various commandline arguments you can give MumbleDJ:

NAME:
   MumbleDJ - A Mumble bot that plays audio from various media sites.

USAGE:
   mumbledj [global options] command [command options] [arguments...]

VERSION:
   v3.1.0

COMMANDS:
GLOBAL OPTIONS:
   --config value, -c value		location of MumbleDJ configuration file (default: "/home/matthieu/.config/mumbledj/config.yaml")
   --server value, -s value		address of Mumble server to connect to (default: "127.0.0.1")
   --port value, -o value		port of Mumble server to connect to (default: "64738")
   --username value, -u value		username for the bot (default: "MumbleDJ")
   --password value, -p value		password for the Mumble server
   --channel value, -n value		channel the bot enters after connecting to the Mumble server
   --p12 value				path to user p12 file for authenticating as a registered user
   --cert value, -e value		path to PEM certificate
   --key value, -k value		path to PEM key
   --accesstokens value, -a value	list of access tokens separated by spaces
   --insecure, -i			if present, the bot will not check Mumble certs for consistency
   --debug, -d				if present, all debug messages will be shown
   --help, -h				show help
   --version, -v			print the version

NOTE: You can also override all settings found within config.yaml directly from the commandline. Here's an example:

mumbledj --admins.names="SuperUser,Matt" --volume.default="0.5" --volume.lowest="0.2" --queue.automatic_shuffle_on="true"

Keep in mind that values that contain commas (such as "SuperUser,Matt") will be interpreted as string slices, or arrays if you are not familiar with Go. If you want your value to be interpreted as a normal string, it is best to avoid commas for now.
