var plucker = require('image-plucker'),
    spawn = require('child_process').spawn,

    ffmpeg = spawn('ffmpeg', ['-i', 'rtmp://10.0.0.3:1935/live/cam.stream_360p', '-vcodec', 'png', '-f', 'image2pipe', '-']);

    counter++
    fs.writeFile('file'+counter+'.png', image);
    console.log('file' + counter + '.png');
