How it works

• Get video information via video id.
  • Use URL: http://youtube.com/get_video_info?video_id=
• Parse and decode video information.
  • Download URL in "url="
  • title in "title="
  • Need sinature in "sig="
• Download video from URL
  • Need the string combination of "url+sig"

func main() {
	flag.Parse()
	log.Println(flag.Args())
	usr, _ := user.Current()
	currentDir := fmt.Sprintf("%v/Movies/youtubedr", usr.HomeDir)
	log.Println("download to dir=", currentDir)
	y := NewYoutube(true)
	arg := flag.Arg(0)
	if err := y.DecodeURL(arg); err != nil {
		fmt.Println("err:", err)
	}
	if err := y.StartDownload(filepath.Join(currentDir, "dl.mp4")); err != nil {
