Pi OBS Controls Skill Package

A complete, feature-rich skill package for Pi to control OBS Studio programmatically via WebSocket v5+.

This package enables Pi to manage scenes, control streaming/recording, toggle virtual cameras, adjust audio volumes, change source visibilities, capture screenshots, apply filters, and much more.

🚀 Features

• Scene Management: List, switch, create, and remove scenes.
• Recording & Streaming: Start, stop, pause, and resume. Retrieve stream/recording health and status.
• Audio Controls: Mute/unmute and adjust volumes (in decibels) for microhpones and media inputs.
• Source Management: Locate scene items, toggle visibility, add new inputs, and auto-fit/resize sources to canvas.
• Filters & Transitions: List and manage source filters, switch transitions, and set transition durations.
• Studio Mode: Toggle Studio Mode, set preview scenes, and trigger transitions.
• Replay Buffer & Screenshots: Save replay buffers, and take/save high-quality screenshots from any source.
• Custom Python SDK: Under the hood, this uses a robust, asynchronous Python client built on top of websockets.

📦 Installation

To install this package in your Pi environment, run:

# Install via npm (recommended)
pi install npm:@nukman-salim/pi-obs-controls

# Or install directly from Git
pi install git:github.com/YOUR_USERNAME/pi-obs-controls

---

⚙️ Setup & Prerequisites

1. Enable OBS WebSocket

1. Open OBS Studio.
2. Go to Tools ➔ WebSocket Server Settings.
3. Check Enable WebSocket Server.
4. Take note of the Server Port (default: 4455) and the Server Password.

2. Install Python Dependencies

The skill requires the websockets Python library:

pip install websockets

3. Add Credentials

Create a .env file in the directory where you run Pi (or your skill execution environment) with your OBS WebSocket credentials:

OBS_HOST=localhost
OBS_PORT=4455
OBS_PASSWORD=your_secure_password

---

🛠️ Usage with Pi

Once installed, your Pi coding agent will automatically register the obs-controls skill. You can command Pi using natural language:

• "Switch my active scene in OBS to 'Main Camera'."
• "Start recording and toggle my microphone off."
• "Show me the list of all current audio inputs and their volumes."
• "Fit the 'Webcam' source in scene 'Gaming' to a 1920x1080 canvas."
• "Take a screenshot of the OBS 'Game Capture' source and save it."

---

🐍 Standalone Python Usage

You can also import and use the underlying client directly in your own Python projects:

import asyncio
from skills.obs_controls.obs_controls import OBSWebSocketClient

async def main():
    # Initializes using environment variables (OBS_HOST, OBS_PORT, OBS_PASSWORD)
    client = OBSWebSocketClient()
    
    await client.connect()
    
    # Switch scene and start recording
    await client.set_current_scene("Main")
    await client.start_recording()
    
    # Check status
    status = await client.get_full_status()
    print(f"Active Scene: {status['current_scene']}")
    
    # Toggle mic mute
    await client.toggle_input_mute("Microphone")
    
    await client.disconnect()

if __name__ == "__main__":
    asyncio.run(main())
