node-mjpeg-proxy

A node.js module to proxy MJPEG requests. Supports multiple client consuming a single stream. Fixes an iOS 6 issue with some MJPEG steams. This is an improved version of mjpeg-proxy, this v2 does not use the buffertools dependency and uses the node buffer instead. It also supports .on() events

Installation

From npm:

$ npm install node-mjpeg-proxy

From source:

$ git clone https://github.com/jeroen13/node-mjpeg-proxy.git
$ cd node-mjpeg-proxy
$ npm install

Example

Example Usage

var MjpegProxy = require('node-mjpeg-proxy');
var express = require('express');
var app = express();

app.listen(8080);

// Create Proxy 
var proxy1 = new MjpegProxy('http://192.168.1.17:8082/ptz.jpg');

// Bind proxy to the webserver
app.get('/ptz.jpg', proxy1.proxyRequest);

// Events
proxy1.on('streamstart', function(data){
    console.log("streamstart - " + data);		// [Console output] streamstart - [MjpegProxy] Started streaming http://192.168.1.17:8082/ptz.jpg , users: 1
});

proxy1.on('streamstop', function(data){
    console.log("streamstop - " + data);	// [Console output] streamstop - [MjpegProxy] 0 Users, Stopping stream http://192.168.1.17:8082/ptz.jpg
});

proxy1.on('error', function(data){
    console.log("msg: " + data.msg);		// [Console output] msg: Error: connect ECONNREFUSED 192.168.1.17:8082
    console.log("url: " + data.url);		// [Console output] url: - http://192.168.1.17:8082/ptz.jpg
});

Here, it will create a proxy to the source video feed (http://192.168.1.17:8082/ptz.jpg). You can now access the feed at http://localhost:8080/ptz.jpg.
