Steps to create a node project.


1) Create a folder and open it in terminal. Run the following commands.

npm init

npm install --save @ffmpeg-installer/ffmpeg

2) Open the code in an editor. Create a file and name it server.js

3) Enter the following code. We will use ffmpeg to stream webcam. It takes input, name of the video and audio device of our system.

const spawn = require('child_process').spawn,
{ exec } = require('child_process');
const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path;

const args = ['-loglevel', 'debug', '-threads:v', '2', '-threads:a', '8', '-filter_threads', '2', '-thread_queue_size', '512', '-f', 'dshow', '-i', 'video=YOUR_VIDEO_DEVICE_NAME','-f', 'dshow', '-i','audio=YOUR_AUDIO_DEVICE_NAME', '-pix_fmt', 'yuv420p', 'c:v', 'libx264', 'qp:v', '19','-profile:v', 'high', '-rc:v', 'cbr_ld_hq', '-level:v','4.2', '-r:v', '60', '-g:v', '120', 'bf:v','3', '-refs:v','16', '-f', 'flv', 'rtmp://'];

var proc = spawn(ffmpegPath, args);
proc.stdout.on('data', function(data) {
proc.stderr.on('data', function(data) {
proc.on('close', function() {

You need to provide your audio and video details in the code. For example: ‘video=HP TrueVision HD Camera’ and ‘audio=Microphone (Realtek High Definition Audio)’ .

4) Open the terminal and enter the following command to run your project.

node server.js
