This has been super helpful for downloading videos. Just wish that there are more options to include subtitles if available for a video. Doing it myself has been difficult as not all videos have the same VTT file. Some have JSON subtitle files and the worst is segmented VTT files that each file is only for a 30 seconds segment. Would be very helpful if this can handle all types of subtitles and download a separate SRT or VTT file in conjunction with the mp4 file.
