    1.1.1 • Public • Published


    Get a realtime live video stream from your Parrot AR Drone 2.0 straight to your browser.


    You'll need a decent and current browser and some cpu horsepower. This code uses web-sockets and the incredibly awesome Broadway.js to render the video frames in your browser using a WebGL canvas.

    How to use

    Please see the http.createServer and Express 3.0 examples in the 'examples' dir. You attach the stream to your server like this:

    // in node:
    // note that the 'server' object points to a server instance and NOT an express app.
    // if your drone is on a different IP
    require("dronestream").listen(server, { ip: "" });

    We serve the client in the same manner as Socket.IO. Add a reference to /dronestream/nodecopter-client.js in your template. Then attach the stream to a DOM node:

    <!-- on the client -->
    <script src="/dronestream/nodecopter-client.js"></script>
      // video canvas will auto-size to the DOM-node, or default to 640*360 if no size is set.
      new NodecopterStream(document.getElementById("droneStream"));

    How it works

    The drone sends a proprietary video feed on port 5555. This is mostly a h264 baseline video, but adds custom framing. These frames are parsed and mostly disposed of. The remaining h264 payload is split into NAL units and sent to the browser via web sockets.

    In the browser broadway takes care of the rendering of the WebGL canvas.


    Node-dronestream has gained some stability in the last release. It attempts to recover lost connections to the drone, and it handles multiple clients, disconnections, etc. See "How to use" for API.


    • Triple high fives to Felix 'felixge' Geisendörfer for getting the whole NodeCopter movement started and being extremely helpful in the process of getting this together.

    • André 'zoddy' Kussmann for supplying the drone and allowing me to keep hacking on it, even when he had to cancel the NodeCopter event for himself.

    • Michael Bebenita, Alon Zakai, Andreas Gal and Mathieu 'p01' Henri for the magic of Broadway.js

    • Johann Phillip Strathausen for being a great team mate at NodeCopter 2012 Berlin.

    • Brian Leroux for being not content with the original solution and for cleaning up the predecessor, nodecopter-stream.

    • @karlwestin for picking up where I was to lazy to actually make this usable.
