        # Stream(video).on_progress()
        if down_dir is not None:
            video.download(down_dir)
        else:
            video.download()
        print("Download complete, " + str(title))
        caption = tube.captions.get_by_language_code('en')
        if caption is not None:
            subtitle = caption.generate_srt_captions()
            open(title + '.srt', 'w').write(subtitle)
    except Exception as …
