Video not downloading

[TechPro424]

I wanted to test the package out, so I made a quick gradle project and added this pakage to my dependencies This is my main class (I just copy pasted the example)

/*

package javaytdl;

import java.io.File;
import java.net.MalformedURLException;
import java.util.Comparator;

import io.github.gaeqs.javayoutubedownloader.JavaYoutubeDownloader;
import io.github.gaeqs.javayoutubedownloader.decoder.MultipleDecoderMethod;
import io.github.gaeqs.javayoutubedownloader.stream.StreamOption;
import io.github.gaeqs.javayoutubedownloader.stream.YoutubeVideo;
import io.github.gaeqs.javayoutubedownloader.stream.download.StreamDownloader;

public class App {
    public String getGreeting() {
        return "Hello World!";
    }

    public static boolean download(String url, File folder) throws MalformedURLException {
        YoutubeVideo video = JavaYoutubeDownloader.decode(url, MultipleDecoderMethod.AND, "html");
	//Gets the option with the greatest quality that has video and audio.
	    StreamOption option = video.getStreamOptions().stream()
		.filter(target -> target.getType().hasVideo() && target.getType().hasAudio())
		.min(Comparator.comparingInt(o -> o.getType().getVideoQuality().ordinal())).orElse(null);
	//If there is no option, returns false.
	    if (option == null) return false;
	//Prints the option type.
	    System.out.println(option.getType());
	//Creates the file. folder/title.extension
	    File file = new File(folder, video.getTitle() + "." + option.getType().getContainer().toString().toLowerCase());
	//Creates the downloader.
	    StreamDownloader downloader = new StreamDownloader(option, file, null);
	//Runs the downloader.
	    new Thread(downloader).start();
	    return true;
    }

    public static void main(String[] args) {
        System.out.println(new App().getGreeting());
        try {
			download("https://www.youtube.com/watch?v=p8mXAQ6cPxg", new File("C:\\Users\\<my user>\\Coding\\JavaYTDL\\x.mp4"));
		} catch (MalformedURLException e) {
			e.printStackTrace();
		}
    }
}

I ran the app, but there is no file downloaded in that directory All I get are these messages in the console

Couldn't find the StreamType for the iTag 401
Couldn't find the StreamType for the iTag 400
[Video: true, Audio: true, Container: MP4, VEncoding: H264, VQuality: p720, AEncoding: AAC, AQuality: k192, Format Note: NONE, FPS: f30]

Where have I gone wrong?
