# libpeer - Portable WebRTC Library for IoT/Embedded Device

![build](https://github.com/sepfy/pear/actions/workflows/build.yml/badge.svg)

libpeer is a WebRTC implementation written in C, developed with BSD socket. The library aims to integrate IoT/Embedded device video/audio streaming with WebRTC, such as ESP32 and Raspberry Pi

### Features

- Vdieo/Audio Codec
  - H264
  - G.711 PCM (A-law)
  - G.711 PCM (µ-law)
  - OPUS
- DataChannel
- STUN/TURN
- IPV4/IPV6
- Signaling
  - [WHIP](https://www.ietf.org/archive/id/draft-ietf-wish-whip-01.html)
  - MQTT
