• Supports P2P, SFU broadcasting, and Home Assistant integration

• Signaling options:

  MQTT

  • picamera.js
  • picamera-react-native
  • picamera-web
  • picamera-app - Android

  WHEP

  • Home Assistant WebRTC Camera
  • eyevinn/webrtc-player

  WebSocket

  • picamera.js - SFU signaling & broadcast

Check out the tutorial video or follow these steps.

• Raspberry Pi Zero 2W, 3B, 4B, or 5
• CSI or USB camera (supports libcamera or V4L2)

Use Raspberry Pi Imager to flash Lite OS (or full OS) to SD card.

sudo apt update
sudo apt install libcamera0.5 libmosquitto1 pulseaudio libavformat59 libswscale6 libprotobuf32

wget https://github.com/TzuHuanTai/RaspberryPi-WebRTC/releases/latest/download/pi-webrtc-v1.1.2_raspios-bookworm-arm64.tar.gz
tar -xzf pi-webrtc-v1.1.2_raspios-bookworm-arm64.tar.gz

Use HiveMQ, EMQX, or a self-hosted broker.

• Open picamera-web, add MQTT settings, and create a UID.
• Run the command on your Pi:

  ./pi-webrtc \
      --camera=libcamera:0 \
      --fps=30 \
      --width=1280 \
      --height=960 \
      --use-mqtt \
      --mqtt-host=your.mqtt.cloud \
      --mqtt-port=8883 \
      --mqtt-username=hakunamatata \
      --mqtt-password=Wonderful \
      --uid=your-custom-uid \
      --no-audio \
      --hw-accel # Only Pi Zero 2W, 3B, 4B support hw encoding

• Broadcasting a Live Stream to 1,000+ Viewers via SFU
