obs-hotkey-1.0.31 is not a library.

obs-hotkey

A lightweight Rust daemon for controlling OBS Studio with global hotkeys on Wayland and X11.

Works on Wayland! Uses evdev for direct keyboard input capture, bypassing Wayland's security restrictions.

Features

Wayland & X11 Support — works on both display servers
Single Static Binary — no runtime dependencies
Global Hotkeys — works even when OBS is not focused
Auto-start on Login — systemd user service integration
Auto-reconnect — automatically reconnects if OBS restarts
Multi-keyboard — monitors all connected keyboards
F13-F24 Support — use extra keys as stream deck buttons

Quick Start

# 1. Install
cargo install obs-hotkey

# 2. Run once — shows the setup guide

# 3. Follow the on-screen steps:
#    - Enable OBS WebSocket Server
#    - Add yourself to the input group
#    - Run: obs-hotkey setup

Installation

From crates.io

cargo install obs-hotkey

From GitHub Releases

# amd64
curl -L https://github.com/DraconDev/obs-wayland-hotkey/releases/latest/download/obs-hotkey-x86_64-unknown-linux-gnu -o obs-hotkey
chmod +x obs-hotkey
sudo cp obs-hotkey /usr/local/bin/

# ARM64
curl -L https://github.com/DraconDev/obs-wayland-hotkey/releases/latest/download/obs-hotkey-aarch64-unknown-linux-gnu -o obs-hotkey
chmod +x obs-hotkey
sudo cp obs-hotkey /usr/local/bin/

From source

git clone https://github.com/DraconDev/obs-wayland-hotkey.git
cd obs-wayland-hotkey
./install.sh    # builds and runs setup

Setup

1. Enable OBS WebSocket Server

Open OBS Studio
