Plucks images from an image output stream. Supports png and jpeg.
Ideal for ffmpeg image2pipe output.
Inspired from https://github.com/stigdreyer/png-plucker
npm install image-pluckervar plucker = require('image-plucker'),
spawn = require('child_process').spawn,
fs = require('fs'),
counter = 0,
ffmpeg = spawn('ffmpeg', ['-i', 'rtmp://10.0.0.3:1935/live/cam.stream_360p', '-vcodec', 'png', '-f', 'image2pipe', '-']);
// You can replace 'png' with 'jpeg' for jpeg images.
plucker(ffmpeg.stdout, 'png', function (error, image) {
counter++
fs.writeFile('file'+counter+'.png', image);
console.log('file' + counter + '.png');
});
