Playlist extraction error

[BrdEase]

Trying the example code from the "usage" section, as follows:

import com.github.kiulian.downloader.YoutubeDownloader;
import com.github.kiulian.downloader.YoutubeException;
import com.github.kiulian.downloader.model.YoutubeVideo;
import com.github.kiulian.downloader.model.playlist.PlaylistDetails;
import com.github.kiulian.downloader.model.playlist.PlaylistVideoDetails;
import com.github.kiulian.downloader.model.playlist.YoutubePlaylist;

public class Youtube {

public static void main(String[] args) throws YoutubeException {
	
	YoutubeDownloader downloader = new YoutubeDownloader(); 
	// downloader configurations
	downloader.setParserRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.121 Safari/537.36");
	downloader.setParserRetryOnFailure(1);
	
	String playlistId = "PLjhaAcnXuuftpJKWB21uRzqe-4_d4Uuoj"; // for url https://www.youtube.com/playlist?list=abc12345
	YoutubePlaylist playlist = downloader.getPlaylist(playlistId);
	
	// playlist details
	PlaylistDetails details = playlist.details();
	System.out.println(details.title());
	
	System.out.println(details.videoCount());
	
	// get video details
	PlaylistVideoDetails videoDetails = playlist.videos().get(0);
	System.out.println(videoDetails.title());
	
	System.out.println(videoDetails.index());
	
	// get video
	YoutubeVideo video = downloader.getVideo(videoDetails.videoId());
}

The playlist link is: https://www.youtube.com/playlist?list=PLjhaAcnXuuftpJKWB21uRzqe-4_d4Uuoj
I'm using it's id: PLjhaAcnXuuftpJKWB21uRzqe-4_d4Uuoj

throws this:

Exception in thread "main" java.lang.NullPointerException at com.github.kiulian.downloader.model.AbstractVideoDetails.<init>(AbstractVideoDetails.java:28)

You should really consider making this library more usable, better docs, better examples and explanations, and of couse better Null Pointer Exception avoiding.

Calm down @BrdEase 😢 this is a free library maked for an only person on his free time, its not perfect, but rememmber that its free and @sealedtx do a great job on his free time

unnecessary rudeness v2.0

[Dolanpls]

You are a Java developer, then why you don't fix the problem and create a new PR with the fix?
This is an open community and all are welcome to improve the code

[BrdEase]

unnecessary rudeness v3.0

[Shabinder]

@BrdEase vey rude and demotivating , despite of all the free efforts by developer.
😑

@sealedtx you are doing a great job ,keep up the good work.👍

[BrdEase]

Yeah i was rude af for no reason, I ended using youtube api.

[Dolanpls]

GL with api key limit

[BrdEase]

Enough for non-comercial use, according to this table (https://developers.google.com/youtube/v3/determine_quota_cost)

[Dolanpls]

Then you are very lucky 😂 I had 15 keys and I would need 100 if I use his api because youtube reduced the api key limit one day 90% 🤦🏻‍♂️

[BrdEase]

If I have some free time I'll try to fix this library, and add a search video mechanism. Is there any way to get in touch with the dev?

[sealedtx]

@BrdEase Hi. Sorry for your bad experience. Please, notice that:

1. this library is web scrapper
2. youtube often changes web structure of its pages
3. I don't use this library every minute or even every day to find the errors

THIS DON'T WORK, DON'T LOOSE YOUR TIME TRYING TO MAKE THIS SHIT WORK

Thats why errors are fixed as soon as someone finds it and opens an issue. After reviewing I try to fix it when I have spare time or review PR. I will add something similar to your idea to README, to make people aware of this.

Is there any way to get in touch with the dev?

Sure, PRs are welcomed

There was a problem with extraction of continuationItems (playlist pagination). Fixed in f8cebea available in 2.4.5 release
