rtsp-ffmpeg

Lazy Node.js FFMpeg wrapper for streaming RTSP into MotionJPEG. It runs FFMpeg process only when someone is subscribed to its data event. Every data event contains one image Buffer object.

Installation

  1. Download FFmpeg to your local machine.

  2. Install package in your project npm install rtsp-ffmpeg

Sample

With socket.io library.

Server:

const app = require('express')(),
  server = require('http').Server(app),
  io = require('socket.io')(server),
  rtsp = require('rtsp-ffmpeg');
server.listen(6147);
var uri = 'rtsp://r3---sn-5hn7su7k.c.youtube.com/CiILENy73wIaGQkcfGRribM88BMYDSANFEgGUgZ2aWRlb3MM/0/0/0/video.3gp',
  stream = new rtsp.FFMpeg({input: uri});
io.on('connection', function(socket) {
  var pipeStream = function(data) {
    socket.emit('data', data.toString('base64'));
  };
  stream.on('data', pipeStream);
  socket.on('disconnect', function() {
    stream.removeListener('data', pipeStream);
  });
});
app.get('/', function (req, res) {
  res.sendFile(__dirname + '/index.html');
});

Client (index.html):

<img id="img">
<script src="/socket.io/socket.io.js"></script>
<script>
	var img = document.getElementById('img'),
		socket = io('');
	socket.on('data', function(data) {
		img.src = 'data:image/jpeg;base64,' + data;
	});
</script>
