# 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](http://www.ffmpeg.org/) to your local machine.

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

## Sample

With [socket.io](http://socket.io/) library.

Server:

```javascript

const app = require('express')(),

  server = require('http').Server(app),

  io = require('socket.io')(server),

  rtsp = require('rtsp-ffmpeg');

server.listen(6147);

var uri = 'rtsp://freja.hiof.no:1935/rtplive/definst/hessdalen03.stream',

  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):

### NB! 

this is not efficient example, but simple. For drawing images on canvas please look at this [example](https://github.com/agsh/rtsp-ffmpeg/blob/master/example/index-canvas.html) by [Seikon](https://github.com/Seikon):  

```html



	var img = document.getElementById('img'),

		socket = io('');

	socket.on('data', function(data) {

		img.src = 'data:image/jpeg;base64,' + data;

	});

```

For more detailed example look at [/example/server.js](/example/server.js)

For the large resolution images or IP cameras example check [/example/server-canvas.js](/example/server-canvas.js)

## FFMpeg

```javascript

  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)

  });

```

If you have an error `Error: spawn ffmpeg ENOENT`, you should first install ffmpeg package.

After that, if the starup command differs from `ffmpeg`, you can change it in the static property like this, for example:

```js

FFMpeg.cmd = 'C:\\ffmpeg.exe';

```
