🎬 Rogplay — Cross-Platform Media Streaming Engine
Android · iOS · Web · TV
An open-source, protocol-agnostic media streaming platform built as a single codebase across four platforms.
- ⚙️ Unified playback pipeline parsing HLS, DASH, MP4, MKV, and live IPTV through one abstraction layer — no per-format player logic
- 🔄 Real-time Watch Party system using WebSocket-based state sync — sub-second drift across concurrent viewers
- 🧩 Sandboxed, JavaScript-based addon runtime enabling new content providers to be added without app updates (browser-extension-style plugin architecture)
- 📱 Single React Native + Expo codebase spanning Android, iOS, Web, and TV — maximizing code reuse without sacrificing native playback performance
