the metadata uses the

var exec = require(‘child_process’).exec;

module.exports = {

  get: function(inputfile, callback) {

    try

    {

      exec(‘ffmpeg -i ‘ + inputfile, function(err, stdout, stderr) {

to execute the ffmpeg commands.

var ffmpeg = require('fluent-ffmpeg');
var sys = require('sys');

var proc = new ffmpeg('youtube.flv')
  .withSize('120x90')
  .takeScreenshots({ count: 1, timemarks: [ '00:00:02.000', '6' ] }, __dirname, function(err) {
    console.log('screenshots were saved')
  });
  var ffmpegmeta = require('fluent-ffmpeg').Metadata;

// make sure you set the correct path to your video file
ffmpegmeta.get('youtube.flv', function(metadata) {
   var w=metadata.resolution.w;
   var h=metadata.resolution.h;
   var proc = new ffmpeg('youtube.flv')
  .withSize(w+'x'+h)
  .takeScreenshots({ count: 1, timemarks: [ '00:00:03.000', '6' ] }, __dirname, function(err) {
    console.log('screenshots were saved')
