youtube-dl binary on your system. This is also the directory
where youtube-dlg will auto download the youtube-dl if not
exists so you should make sure you have write access if you
want to update the youtube-dl binary from within youtube-dlg.
cmd_args (string): String that contains extra youtube-dl options
seperated by spaces.
enable_log (boolean): If True youtube-dlg will enable
