MetaRTC Overview

• The easiest WebRTC stack for embedded / IoT / robotics devices
• Code once run everywhere, A pure C version of webRTC
• Linux/RTOS/Windows/Mac/Android/IOS

MetaRTC implements a complete WebRTC stack

• ICE / ICE-Lite
• STUN and TURN (configurable)
• DTLS / SRTP
• Full RTP/RTCP support
• Adaptive bitrate & congestion control
• Flexible media pipelines
• P2P connection logic
• Customizable session/signaling logic
• UDP and optional TCP fallback
• Multi-stream, multi-track support

In short, MetaRTC provides full control, can run in fully offline environments, and is suitable for large-scale product integration.
