jpeg-extractor

The module is designed to work with any streams that contains pictures in jpeg format (not only HTTP, like a mjpeg, but also any other).

Install

npm install jpeg-extractor

Example

Example of extracting images from MJPG stream to the console and written to the directory.

var request = require("regular-request");
var jpegExtractor = require("jpeg-extractor");
var fileOnWrite = require('file-on-write');
 
var url = 'http://root:123@127.0.0.1:11164/axis-cgi/mjpg/video.cgi';
 
var je = jpegExtractor().on('image', function (image) {
    console.log('--> ' + image.toString('hex'));
});
 
var cnt = 0;
var fow = new fileOnWrite({
    filename: function () {
        return 'file_' + (cnt++);
    },
    path: '_output/',
    ext: '.jpg'
});
 
request(url).pipe(je).pipe(fow);

Alternatives

mjpeg-consumer - I like this project. But unfortunately, it works only with HTTP streams. If there are several pictures in the chunk, it does not retrieve them. I used this project as a template for my project. Of course, I'm used a different extraction algorithm.
