var inputFiles = [file]
var globalOptions = '-y' // always overwrite files
var convertOptions = '-preset ultrafast -s 320x200'
var outputFiles = ['output.webm']

window.ffmpeg(globalOptions, inputFiles, convertOptions, outputFiles, {
  onProgress: function(progress) {
    console.log('progress', progress)
  }
