MediaRPC

A minimal Windows application and companion browser extension that displays your exact media playback on Discord Rich Presence.

Unlike standard SMTC-based (System Media Transport Controls) apps that only pull basic metadata, MediaRPC uses a custom WebSocket browser extension to extract full media data directly from the official Media Session API. This allows it to synchronize live playback duration timestamps, extract beautiful high-resolution album artwork, display the source domain, and construct direct "Open Link" action buttons right in your Discord status!

Features

• 🌐 Full Extension Integration - Uses a zero-install, unpacked Chrome/Edge extension to safely pipe native browser media over local WebSockets.
• 💬 Discord Rich Presence - Shows what you are listening to on your Discord status.
• 🎨 Two Unique Layouts - Instantly toggle between:
  • Classic: The traditional "Listening to Music" header.
  • Dynamic: A custom header that cleanly displays the specific source domain ("Listening to youtube.com").
• ⏱️ Live Timeline Sync - Perfect duration progress bar visually ticking inside your Discord presence.
• 🔗 Actionable "Open Link" Button - Automatically adds a clickable button to your Discord profile so friends can instantly tune in with you.
• 🖼️ WPF Desktop UI - A sleek, modern dashboard that displays current play state, artwork, local playback progress, and a list of your other concurrent media sessions.
• 🔄 Auto-Connect - Automatically detects when Discord starts, connects, and elegantly disconnects when you close it.

Requirements

• Windows 10/11
• .NET 8.0 Runtime
• Discord Desktop App
• Chromium-based Browser (Chrome, Edge, Brave, etc.)

Installation & Setup

1. Build and Run the App

git clone https://github.com/danyooooo/MediaRPC.Wpf.git
cd MediaRPC.Wpf
dotnet build -c Release

Run the MediaRPC.exe. The application automatically spins up a local WebSocket listener.

2. Install the Browser Extension

1. Open your Chromium browser (Chrome/Edge) and navigate to the Extensions page (chrome://extensions/ or edge://extensions/).
2. Enable Developer mode in the top right corner.
3. Click Load unpacked.
4. Select the ChromeExtension folder located inside your cloned MediaRPC directory.
5. Done! The extension will automatically connect to the WPF app via WebSockets. No native messaging registry hacks required!

⚠️ Note on Incognito Mode: If you enable "Allow in incognito" for the extension, you must restart your browser for it to properly take effect. Otherwise, the extension will encounter a "context invalidated" error and fail to connect until restarting.
