A simple ffmpeg wrapper for streaming video from a [DJI Tello Drone](https://www.ryzerobotics.com/tello) or a [Raspberry Pi](https://www.raspberrypi.org/).

## Installation

```

$ npm install node-red-contrib-ffmpeg

```

> **Note:** This node requires that you have [ffmpeg](https://ffmpeg.org/) installed on your machine.

## Configure your node

Open the node's configuration panel to set `Device Type` and the `Stream URL`.

> **Note:** In this example our stream will be accessible at `ws://:/stream`

## Using the stream

To render the video stream in the browser, we use a library called [JSMpeg](https://github.com/phoboslab/jsmpeg).

```html

  

    

    

    

    

    

      const videoCanvas = document.getElementById('video-canvas')

      

      // The stream URL that we set in the previous step.

      const url = `ws://${window.location.hostname}:${window.location.port}/stream`

      new JSMpeg.Player(url, { canvas: videoCanvas })

    

  

```

## Device specific instructions

There are a few minor hardware specific steps depending on your device.

### Tello Drone

Before you can use your Tello Drone you **MUST** activate it in the official Tello Drone app.

Once your drone is activated, you can connect to it's WiFi Network `TELLO-XXXXXX` and send it commands via UDP.

In the example flow, to start the video stream, click the `command` command followed by `streamon` command.

Check out this [blog post](https://dev.to/poojamakes/detecting-objects-with-a-tello-drone-38np) to get started

### Raspberry Pi

Before you can stream with a Raspberry Pi, you will need to attach a camera and enable it.

To enable camera support, run the following command:

```

sudo raspi-config

```

Then use the arrow keys to choose _Interfacing Options_ > _Camera_ and select to enable the camera. Once the camera is enabled, reboot your Raspberry Pi.

> **Note:** For the most up-to-date instructions for Raspberry Pi Camera setup, check out the [official documentation](https://www.raspberrypi.org/documentation/configuration/camera.md).

The Raspberry Pi will start streaming as soon as you start node red.
