<p> Переменная хранит имя файла настроек, который содержит параметры,
перечисленные в массиве опций <a href="#robo5">config</a>, в формате XML. При отсутствии
параметра или пустом значении соответствующие флаги а аргументы не
добавляются в итоговую команду ffmpeg. Таким образом, например, можно
включать или отключать ведение журнала сохранения аудиозаписей, просто
указывая или удаляя параметр archive_log.
