What is prusa-connect-rtsp?

Inspired by nunofgs on GitHub and with the help of BillyAB, this project simplifies using RTSP and MJPEG cameras with Prusa Connect.

FFmpeg is used to take periodic snapshots of an RTSP or MJPEG camera stream, then curl is used to pass it through to the Prusa Connect Camera API. By default, snapshots are taken and sent every 10 seconds, with an additional interval of 1 second per camera configured.

Personally, I have it running 5 RTSP streams from Eufy C24 Wi-Fi cameras on a single Raspberry Pi Zero 2W, without issue.

Getting Prusa Connect Tokens

It's best to consult Prusa's official documentation, as the interface may change over time, but the steps below should point you in the right direction:

  1. Open Prusa Connect web interface
  2. On a printer dashboard, go to the Camera tab
  3. Click Add new other camera
  4. Give the camera a name (optional)
  5. Copy the token
  6. Paste the token in to your docker-compose file or docker command

Note: If setting up multiple cameras, the order of your camera stream URLs should match the order of your tokens.

Usage

Camera stream URLs and Prusa Connect tokens are passed through to the script using environment variables. Single camera stream URLs and tokens can be specified, or multiples can be added by separating them with a comma. Below are some examples of how to run the container using Docker Compose or the Docker CLI.

docker compose (recommended)

version: '3.8'
services:
  prusa_connect_rtsp:
    image: jtee3d/prusa_connect_rtsp:latest
    restart: always
    environment:
      CAMERA_URLS: >
        rtsp://username:[email protected]/live0,
        http://username:[email protected]/stream.mjpeg,
        rtsp://username:[email protected]/live0
      TOKENS: >
        5dvoIByhfG7AeODTiNNk,
        MdVaUadfw93MBdlZSlqM,
        fejnJhrhCGncXsDU0R8S

docker cli

docker run \
  -e CAMERA_URLS="\
rtsp://username:[email protected]/live0,\
http://username:[email protected]/stream.mjpeg,\
rtsp://username:[email protected]/live0" \
  -e TOKENS="\
5dvoIByhfG7AeODTiNNk,\
MdVaUadfw93MBdlZSlqM,\
fejnJhrhCGncXsDU0R8S" \
  jtee3d/prusa_connect_rtsp:latest

Optionally, the following environmental values can be speficified:

  • FRAME_CAPTURE_DELAY (default: 1, used as the delay between multiple cameras)
  • CAMERA_CYCLE_DELAY (default: 10, used as the delay after all cameras have been processed, before looping through them again)
  • CONNECTION_TIMEOUT_DELAY (default: 5, timeout for ffmpeg and curl)
