INSTALLATION

###YOUTUBE API KEYS Effective April 20th, 2015, all requests to YouTube's API must use v3 of their API. Unfortunately, this means that all those who install an instance of the bot on their server must create their own API key to use with the bot. Below is a guide of the steps you must take to get proper YouTube support.

Important: MumbleDJ will simply not work anymore if you do not follow these steps and create a YouTube API key.

1) Navigate to the Google Developers Console and sign in to 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". Click the "Server key" option.

5) Add the IP address of the machine MumbleDJ will run on in the box that appears. Click "Create".

6) You should now see that an API key has been generated, make a note of it.

###SOUNDCLOUD API KEYS A SoundCloud API key is required for SoundCloud integration. If no SoundCloud API key is found, then the service will be disabled (YouTube links will still work however).

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

2) Now to get the API key create a new app here: http://soundcloud.com/you/apps/new

3) Make a note of the Client ID (not the Client Secret).

NOTE: If you get errors when trying to play SoundCloud audio, make sure to update youtube-dl with youtube-dl -U!

###SETUP GUIDE
1) Install and correctly configure Go (1.4 or higher). Specifically, make sure to follow this guide and set the GOPATH environment variable properly.

2) Install ffmpeg and mercurial if they are not already installed on your system. Also be sure that you have opus and its development headers installed on your system, as well as openal (check your distributions repo for the package name). If you want to use avconv from libav instead of ffmpeg you must make the necessary change in the configuration file.

3) Install youtube-dl. It is recommended to install youtube-dl through the method described on the linked GitHub page, rather than installing through a distribution repository. This ensures that you get the most up-to-date version of youtube-dl.

4) If you wish to install MumbleDJ without any further root privileges, make sure that ~/bin exists and is added to your $PATH. If this step is not done, the Makefile will place the MumbleDJ binary in /usr/local/bin instead, which requires root privileges.

5) Clone the MumbleDJ repository or download the latest release.

6) cd into the MumbleDJ repository directory and execute the following commands:

$ make
$ make install

7) Edit ~/.mumbledj/config/mumbledj.gcfg to your liking, make sure to include your API keys! This file will be overwritten if the config file structure is changed in a commit, but a backup is always stored at ~/.mumbledj/config/mumbledj_backup.gcfg.

8) Execute the command shown at the top of this README document with your credentials, and the bot should be up and running!

Recommended, but not required: Set opusthreshold=0 in /etc/mumble-server.ini or /etc/murmur.ini. This will force the server to always use the Opus audio codec, which is the only codec that MumbleDJ supports.

###UPDATE GUIDE 1) git pull or download the latest release.

2) Issue the following commands within your updated MumbleDJ directory:

$ make clean
$ make
$ make install

NOTE: It is very important that you use make instead of make build when updating MumbleDJ as the first option will grab the latest updates from MumbleDJ's dependencies.

3) Check to make sure your configuration in ~/.mumbledj/config/mumbledj.gcfg is the same as before. If it is back to the default, a backup should have been created at ~/.mumbledj/config/mumbledj_backup.gcfg so you can copy the values back over.

TROUBLESHOOTING

YouTube videos downloads work when using youtube-dl but not within MumbleDJ.

This is likely related to how you set up your Google account for the YouTube API. Specifically, make sure you you try using an IPv4 server address in the list of allowed IPs if you were using IPv6 previously.

Whenever the !add command is used I receive the following message in chat: "The audio download for this video failed. YouTube has likely not generated the audio files for this video yet. Skipping to the next song!"

First, make sure you have youtube-dl installed and it is the latest version. MumbleDJ makes use of youtube-dl's -- commandline argument which is not supported in older versions.

If this doesn't fix the issue, try the following fix from @MrKrucible:

I fixed it by following the instructions here to set default arguments: https://github.com/rg3/youtube-dl/blob/master/README.md#configuration

For the lazy...

• 1. First make ~/.config/youtube-dl/ and create a file named config.
• 1. Then put --force-ipv4 into the config. Nothing else needs to be in there unless you want to add more arguments.

I receive the following error when compiling MumbleDJ: "undefined: tls.DialWithDialer"

This issue is caused by having an outdated version of Go. Make sure you are using the latest available version of Go.

I can't get MumbleDJ to compile correctly under gccgo

Unfortunately MumbleDJ likely will not work with gccgo. MumbleDJ is developed and tested on vanilla Go.

I receive the following message when compiling MumbleDJ: "local.h:6:19: error: AL/alc.h: No such file or directory"

Don't worry about it. The compilation went through successfully, OpenAL is not needed by the bot.

I receive the following message when building MumbleDJ: "cannot create <nil>/go.o: No such file or directory"

Execute the following before building:

export TMPDIR=/tmp
