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.

更改了ffmpeg的转码配置

当我解码输入rtsp的视频流时，一切正常，但是我们采用的海康摄像头通过映射端口用外网访问会解码失败，虽然映射使用了UDP/TCP协议，还需要ffmpeg强制使用TCP协议转码。

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>

FFMpeg

  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)
  });
