Synopsis

Minimal RPI camera server using node.js. See the simple cam view repo for streaming/displaying the camera on your device.

Requirements

• Node.js
• npm
• raspistill (for images)
• ffmpeg (for streaming)

Usage

For websLinux virtual video device node must also be loaded. Specifically, server runs ffmpeg on input node /dev/video0.

For actual streaming, the video stream will be grabbed from /dev/video<X>. If the virtual device does not show up, load the bcm2835-v4l2 device driver module:

sudo modprobe bcm2835-v4l2

1. Install the only depedency (needed if "streaming")

   npm install

2. Update config.js as necessary
3. Start server on server

   node src/server

4. Then there are different options on the client machine:
   • Open http://HOST:PORT/?u=USERNAME&p=PASSWORD in browser.
   • Open http://HOST:PORT/stream?u=USERNAME&p=PASSWORD in browser.
   • Send GET request to http://HOST:PORT/pi.jpg?u=USERNAME&p=PASSWORD to fetch latest image.
   • Open a websocket connection to ws://HOST:PORT/stream, and send authentication token (fixed string) on connect.

USERNAME, PASSWORD, and PORT are specified in config.js.
