Streaming webcam via websocket using Node.js and soccket.io

This allows a server to stream a webcam, using only html5 with no browser plugins, the main idea is to take pictures from the camera and stream them in real time.

This is not as fast as Using webRTC, but it is an alternative where webRTC doesn´t work (in this case, in a Samsung Smart Signage Platform (SSSP) 4.0 display).

To get started with developing using the Socket.IO, you need to have Node and npm (node package manager) installed. If you do not have these, head over to Node setup to install node on your local system. Confirm that node and npm are installed by running the following commands in your terminal.

node --version
npm --version

You should get an output similar to −

v5.0.0
3.5.2

we need to install Express and Socket.IO. To install these and save them to package.json file, enter the following command in your terminal, into the project directory.

npm install --save express socket.io

One final thing is that we should keep restarting the server. When we make changes, we will need a tool called nodemon. To install nodemon, open your terminal and enter the following command −

npm install -g nodemon

Whenever you need to start the server, instead of using the node app.js use, nodemon app.js. This will ensure that you do not need to restart the server whenever you change a file. It speeds up the development process.

To start the server, download the repository and go to the path and run:

nodemon app.js

Then in the web browser go to: http://127.0.0.1:3000
