StreamDeck-Discord

StreamDeck-Discord is a C++ plugin for the Elgato StreamDeck for controlling self-mute and self-deafen in the Discord app.

Installation

Installation and demo video: https://youtu.be/MSMbRtj2fFA

Download the com.fredemmott.discord.streamDeckPlugin file from the releases page, and double-click it.
Add a mute or deafen button to your streamdeck
Go to the Discord developer portal, and create an application
Go to 'OAuth2' on the left hand side
Add https://localhost/ as a redirect URI
go back to 'General Information'
copy the client ID and paste it into 'app ID' in the StreamDeck button properties
copy the client secret and paste it into 'app secret' in the StreamDeck button properties
Discord should now ask you for permission a few times, then you're done :)
You might get a firewall prompt. You need to allow it.

Need Help?

Double-check everything exactly matches. https://localhost/ is not the same as https://localhost, or http://localhost/
If that does not resolve the problem, sign up/sign in to github, and click 'New discussion' on https://github.com/fredemmott/StreamDeck-Discord/discussions ; create an entry in the "Help" category

I'm not able to offer 1:1 help, e.g. via Discord.

Limitations

only one application can control Discord voice settings at a time. Stop anything else that controls Discord mute/deafen, such as the Discord applet in Logitech Gaming Software
mute/deafen only apply while the application is running. For example, if you mute the microphone, then quit the StreamDeck software, the microphone might not be muted.

These limitations are imposed by Discord and can not be fixed by this plugin.

Why does this plugin ask for my Discord username and avatar?

This information is not used or shared by the plugin. It asks for this permission as if it doesn't, Discord will separately prompt for it anyway, even though it's not wanted. Asking for it up front means you will get one permission prompt instead of two.

Why does this plugin ask my firewall for permission to access the internet?

Discord plugins use OAuth2. The flow is basically:

this plugin asks the local Discord app for a code
the Discord app gives this plugin a code
the plugin asks the Discord web API to convert the code into an OAuth token
the Discord API gives the plugin the token
the plugin uses the token to log in to the client

The third step requires internet access.

Why does this plugin require me to register an app with Discord?
