OBS Bridge - Layer for Live YT Like Platforms.

🧩 Problem Statement

Modern live streaming workflows (especially using OBS) require fine-grained control over individual video streams — not just a fixed layout.

However, existing video conferencing tools:

❌ Provide only pre-defined layouts (grid, speaker view)
❌ Do not expose raw per-user video streams
❌ Cannot be directly integrated into OBS as independent sources

This creates a major limitation for:

  • Live streamers
  • Podcast creators
  • Online events & interviews
  • Multi-person broadcasts

👉 You are forced to either:

  • screen capture layouts (low quality, no control), or
  • build complex custom pipelines.

🧠 Existing Solution (Closed Ecosystem)

There are tools like ping.gg that solve this problem by:

  • Providing individual stream URLs per participant
  • Allowing OBS ingestion via browser sources
  • Enabling dynamic switching and layouts

But:

❌ These systems are closed-source
❌ No transparency in architecture
❌ Limited flexibility for developers
❌ Cannot be self-hosted or customized deeply

🚫 Why No Open Source Version Exists (Yet)

Building this system is non-trivial, because it requires combining multiple hard problems:

1. ⚙️ Real-Time Media Infrastructure

WebRTC + SFU (mediasoup)
Low latency streaming
Bandwidth optimization

2. 🔄 Dynamic Stream Routing Layer

Mapping users → streams → viewers
Handling joins/leaves in real-time
Switching streams without breaking playback

3. 🎛 Broadcast Control System

Slots / scenes / layouts
Host-controlled routing
State synchronization across clients

4. 🖥 OBS Integration Layer

Browser source compatibility
Stable stream endpoints
Decoupled viewer pipeline

5. 🧠 System Design Complexity

Separation of concerns:
- communication layer
- media routing layer
- presentation layer

Most open-source WebRTC projects stop at:

✔ video calling
✔ basic SFU

…but do not go into broadcast-grade routing systems.

💡 What This Project Solves

This project aims to:

✔ Bring this architecture to open source
✔ Enable OBS-first streaming workflows
✔ Provide raw access to individual streams
✔ Decouple media transport from presentation

👉 Essentially:

Turning WebRTC SFU into a programmable live streaming backend

🎯 One-Line Vision

An open-source alternative to ping.gg — built for developers who want full control over live streaming pipelines.
