    //Luis Fonsi - Despacito ft. Daddy Yankee
    String videoUrl = "https://www.youtube.com/watch?v=kJQP7kiw5Fk";
    VideoInfo info = getDownloadInfo(videoUrl);

    //there are many options of what to download (only video, video and audio, only audio)
    //simpleDownloadOption has video, audio, and good quality
    String downloadUrl = info.simpleDownloadOption.url;
