Maybe am i doing something wrong ? (i have release 2.2.2)

Thx for your help.

Hello,

I am using currently your library to download videos(audio from video) from YouTube. It was working fine, before some time. Now, when I am trying to get audio formats by calling the function audioFormats on the instance of YouTubeVideo class, it returns null. I have dug into the problem and figured out the problem is in the DefaultParser. The function parseFormat checks whether given JSON object contains cipher keyword, if it is true, the parser retrieves it and then does necessary steps.
So, the problem is with the cipher field in the json. Now, this field is called signatureCipher.
I guess YouTube has changed a response structure again. By the way, I have created a custom parser and fix this error and it works fine. But, I prefer to use your default parser rather than creating my own, which is actually the same.

So, I hope you fix the issue as soon as possible:)

I noticed that if there are multiple AudioFormats for audio download, not all formats get to a .m4a file, but some get to a .weba file.
Is there a way to avoid that?

If video is live stream or already finished stream - video.videoWithAudioFormats() and video.videoFormats() are empty

I can't parsing this from URL -> https://www.youtube.com/watch?v=OtIMeAt2lTY
And i found the 'ytplayer.config' was empty, how can i parse that URL and get a video data?

It was fine when i tested it locally, but can't parsing when i tested it my product server

please document to see what is happening under the hood

Hey there!

I'm currently experiencing an issue where I'm unable to get playlist-details, because apparently for some playlists (like OLAK5uy_kiTxC7OplYPiaW4EqzAdqmtguAY7s7f2g) the JSON element sidebar.playlistSidebarRenderer.items[1] does not exist (index 0 does exists though):

Caused by: java.lang.IndexOutOfBoundsException: Index 1 out of bounds for length 1

at [email protected]/com.github.kiulian.downloader.YoutubeDownloader.getPlaylist(YoutubeDownloader.java:87)
<my code...>

It's this part of the code that throws the exception (at DefaultParser#getPlaylistDetails(String, JSONObject):216):

JSONArray sideBarItems = initialData.getJSONObject("sidebar").getJSONObject("playlistSidebarRenderer").getJSONArray("items");
String author = sideBarItems.getJSONObject(1)
    <...>

Here's what I did: (this should be correct, right?)

YoutubePlaylist playlist = new YoutubeDownloader().getPlaylist("OLAK5uy_kiTxC7OplYPiaW4EqzAdqmtguAY7s7f2g");

It worked fine with the Bruce lee playlist (PLC3w7RzH8Yf9Zhgk43XX2w_HEDNptS-Ca) from the YoutubePlaylistTest.

Any idea what to do?

Its possible to download audio formats , like m4a , but i am just wondering is there a way to download audio in mp3 file format ?
If not , is there any plan to implement that?

Hi,

With default Parser and default Extractor, the InputStreamReader that reads from HttpURLConnection inputstream uses default character encoding. In my case it was not a utf-8 what results in missing non ASCII characters in video details.

The simple solution is to explicitly specify the utf-8 charset:

BufferedReader in = new BufferedReader(new InputStreamReader(
                        connection.getInputStream(), StandardCharsets.UTF_8));

What I can also suggest is to use dependency injection to inject extractor in default parser, it would make life easier when man needs to alter just a default extractor and use derived version with default parser.

Hi bro, very nice work, i love it, at now fails in all videos:

W/System.err: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String java.lang.String.replace(java.lang.CharSequence, java.lang.CharSequence)' on a null object reference
W/System.err: at com.github.kiulian.downloader.model.formats.Format.(Format.java:55)
W/System.err: at com.github.kiulian.downloader.model.formats.AudioVideoFormat.(AudioVideoFormat.java:39)

Maby something related to Cypher ?

So if I do not want to download it, but watch it in the browser while being streamed (HLS), how can I get the right URL? Because if I use the videoWithAudioFormats.get(0).url() I get a URL which does not work with a 500 Internal Server Error.
However if I just download it, it works File file = video.download(videoWithAudioFormats.get(0), outputDir);.
Any tips here?

Please Is there a way i can get the video thumbnail

.formats() always returns an empty list

Hello,

link of the video : https://www.youtube.com/watch?v=QUvVdTlA23w

When i try to parse the video, i have this error :
com.github.kiulian.downloader.YoutubeException$BadPageException: Could not parse player config json
at com.github.kiulian.downloader.parser.DefaultParser.getPlayerConfig(DefaultParser.java:72)
at com.github.kiulian.downloader.YoutubeDownloader.getVideo(YoutubeDownloader.java:65)

I don't know if there are others links which give this error.

Hi,

First of all I would like to appreciate the tremendous work which you have done here.
Now, I tried running the app on my local and found that in the method parseFormat(JSONObject json, JSONObject config) you have a check for "cipher" which should be replaced with "signatureCipher" imo. Do let me know if this is a valid bug.
Also, you you have anything in pipeline related to downloading videos from playlist. As of now, whenever I try to download something from playlist, it throws me an error.
I will try to contribute related to playlist if you dont have it in the pipeline. Happy to help

Thanks

Hi guys,

Great library, but it looks like youtube is kinda trying to block you from downloading the urls. I implemented your library as said in the README. The library find the urls, but then downloading is impossible. Any idea what's causing this?

I am trying to download the following youtube using the library.
https://www.youtube.com/watch?v=wujFJXU4N8Y

The returned YoutubeVideo object contains 2 AudioVideoFormat objects.
And the second one with videoQuality = hd720p has null contentLength.

So when my program call downloadAsync(format, outDir, listener), exception occurs in:
int newProgress = (int) ((total / format.contentLength()) * 100);

I have been battling with this error for a long time now. I am using maven with intellij ide ultimate

When I download the video with findVideoWithQuality(VideoQuaity.large).. Only video downloaded.. Not Audio.

I have gone through every possible function but didn't find any clue.

What if I wanna download Specific video format with specific audio format.

Any help appreciated..

Hi again bro !, today i have this error in some videos, this zr6HHU0fxOA for example:

I hope you can help me, great job i love your work.

Thanks you very much.

Hello,

Thanks so much for this library.

i am stuck at this line.

Future future = video.downloadAsync(format, outputDir);

What are the available formats to pass in the constructor

Seems that Google changed again some things so the library throws an exception:

com.github.kiulian.downloader.YoutubeException$CipherException: Transofrm object not found

Example link not working:

Do you have any plans for playlist support?

There's a video which is available in 1080p but I can only download it in 360p with this tool. How can I fix that and why is YouTube hiding the more high quality options?

For the Video-ID:
https://www.youtube.com/watch?v=5pXVLqupV3o

I get the Exception:
Exception in thread "main" com.github.kiulian.downloader.YoutubeException$VideoUnavailableException: Video unavailable
at com.github.kiulian.downloader.YoutubeDownloader.getVideo(YoutubeDownloader.java:76)

What is wrong with the ID?
I hope you can help me!

please document to see what is happening under the hood

Have you considered a method to return a fragment of the video from a second to another second. So if the video has 15 min of duration, and I want only the fragment between the time from 1:30 min to 2:45 min, have a method to get this fragment instead of the whole video.

I am trying to download Videos in higher resolution like Full HD or 4k, but unfortunately I am just able to download in a resolution of 720p.

Hi,

It seems that we cannot download the video when we have to accept the inappropriate content of the video.
Idk if i'm understandable so i give you some links to understand the problem :
https://www.youtube.com/watch?v=Nkwhj96kVyU
https://www.youtube.com/watch?v=QQhj1ckZwBQ

For these videos, the link goes from https://www.youtube.com/watch?v=XXX to https://www.youtube.com/watch?v=XXX&has_verified=1 .

Can't use this library for android application with Android OS API level < 19 (4.4 (Kitkat)) as StandardCharsets class has been added for 19+ API level only.

Thank you.

Sorry. It's wrong issue

Hi,
Downloading a "regular" format (audio+video) is fast enough.
But for an "adaptive" format (video or audio only), the download starts, stops for seconds, then restarts, and so on.
To avoid this, it can be done part by part, using some extra parameters in each request:

• range: first and last byte positions
• part number: incremented at each request
• client version: found in the initial data

com.github.kiulian.downloader.YoutubeException$VideoUnavailableException: Could not load url:

Add a way to get subtitles and pass them to java (it doesn't matter if they have timing)

how to make a call to function like: val video = ytDownloader?.getVideo(data.id),

As its been reporting as Inappropriate blocking method call, Even when Inside: withContext(Dispatchers.IO){}

So how to make this work asychronous...? even intellij is reporting Inappropriate blocking method call

Correct me if I am Wrong somewhere...,Thanks in Advance.

I have tried the exact code, as mentioned in README to test a download.
Regardless of the itag and link used, the Video has no sound in it.

is there any issue with that?

Errors sometimes occur.
Please check the error below.

This error occurs with signature.
when I brought the html code, it did not include 'assets'.

I'm trying to use it in a personal project. I created a jar with your code but i can't make it work.

The same code works if i create a new class in your project, but if i use your project as a jar and i import that jar it doesn't.

This is the code that i'm using

String link = "NeQM1c-XCDc";
YoutubeDownloader youtubeDownloader = new YoutubeDownloader();
YoutubeVideo video = null;
File outputDir = new File(System.getProperty("user.home").concat("\Downloads\yt"));
outputDir.mkdir();
try {
video = youtubeDownloader.getVideo(link);
} catch (YoutubeException e) {
e.printStackTrace();
}
try {
assert video != null;
video.download(video.audioFormats().get(0),outputDir);
} catch (YoutubeException | IOException e) {
e.printStackTrace();
}

This is the exception
Exception in thread "main" java.lang.NoClassDefFoundError: com/alibaba/fastjson/JSON at com.github.kiulian.downloader.parser.DefaultParser.getPlayerConfig(DefaultParser.java:87) at com.github.kiulian.downloader.YoutubeDownloader.getVideo(YoutubeDownloader.java:69) at com.main.App.main(App.java:27) Caused by: java.lang.ClassNotFoundException: com.alibaba.fastjson.JSON at java.net.URLClassLoader.findClass(URLClassLoader.java:382) at java.lang.ClassLoader.loadClass(ClassLoader.java:418) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:355) at java.lang.ClassLoader.loadClass(ClassLoader.java:351) ... 3 more
