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.
-
Download FFmpeg to your local machine.
-
Install package in your project
npm install rtsp-ffmpeg
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>
For large images resolution or IP cameras example check /example/server-canvas.js
var ffmpeg = new FFMpeg({
input: 'rtsp://localhost' // stream uri
, rate: 10 // output framerate (optional)
, resolution: '640x480' // output resolution in WxH format (optional)
, quality: 3 // JPEG compression quality level (optional)
});
