Youtube cannot be play or extracted

[schlector-code]

Since Yesterday YouTube cannot play, can you take a look at it with priority?

[nhCoder]

I will look into it tonight

[craftbox2245]

Error : While getting YouTube Data: Attempt to invoke virtual method 'int java.lang.String.lenght()' on a null object reference
YouTube can not extracted
Please Help us as soon as possible @nhCoder

[nhCoder]

its works now IDK but it works please check and tell me again

[schlector-code]

its works now IDK but it works please check and tell me again
No, it still not working, failing with number of videos like Vevo videos.

[hhyeok1026]

I confirmed that there was a problem on November 23rd.

The response value from YouTube has changed.
However, there were times when a specific video of a specific device appeared as an existing response. So it could seem like it was going well.
When it came out with the existing response structure, the new changed values were mixed.

So I modified it to work with YouTube's new changes and made sure it works on all devices.

=======================================================
I want to do a pull request, but I have to do the project I am doing now, so I will leave the source here.
================================================== =====

1.PlayerResponse.java
The playerJs value in Response.java has been moved to PlayerResponse.

private String playerJs; //add

//add
public void setPlayerJs(String playerJs){
this.playerJs = playerJs;
}

public String getPlayerJs(){
if( playerJs.startsWith("http") && playerJs.contains("youtube.com") ){
return playerJs.replace("\\", "");
}
else{
return "https://www.youtube.com" + playerJs.replace("\\", "");
}
}

=============================================

2. YoutubeStreamExtractor.java

2-1) Change member variable of YoutubeStreamExtractor class.

//String regexPlayerJson="(?<=ytplayer.config\\s=).*?((\\}(\n|)\\}(\n|))|(\\}))(?= ;)"; //delete
 String regexPlayerJson="(?<=ytInitialPlayerResponse\\s=).*?(\\}\\]\\})(?=;)"; //add  //The regular expression I created may be unstable..

//private Response response; //delete
PlayerResponse playerResponse; // From local variable to member variable

2-2) in doInBackground()

 playerResponse = parseJson(jsonBody); //Receive as a member variable
            //response.setPlayerJs(RegexUtils.matchGroup(PlayerBaseRegex, body)); //delete playerResponse.setPlayerJs(RegexUtils.matchGroup(PlayerBaseRegex, body)); //add

2-3) Change parseJson() to the source below.

private PlayerResponse parseJson(String body) throws Exception {
JsonParser parser=new JsonParser();
return new GsonBuilder().serializeNulls().create().fromJson(parser.parse(body), PlayerResponse.class);
}

2-4)in parseUrls()

//decodedSig = CipherManager.dechiperSig(URLDecoder.decode(partCipher.replace("s=", "")), response.getPlayerJs()); //delete
decodedSig = CipherManager.dechiperSig(URLDecoder.decode(url_part.replace("s=", "")), playerResponse.getPlayerJs()); //add

@hhyeok1026 hello. thank you for your updated code and I have made changes on the code according to your code. But the error is still there. can you suggest anything?

hey no need to modify anything the original code is working

[NiazSagor]

@nhCoder sorry brother, it's still not working. strange though, it was working just fine since I have implemented it. I did not change anything but the error just landed out of no where. I do not know what to do. I have a project that heavily depends on this.

[nhCoder]

just check the apk for test and tell me again

[schlector-code]

@nhCoder Please check with other YouTube video like VEVO videos, it is more likely to fell in the problem. and Test with different device.

@nhCoder Please check with other YouTube video like VEVO videos, it is more likely to fell in the problem. and Test with different device.

please send me the links

[hhyeok1026]

@nhCoder

In my case

on a galaxy A9 device
https://www.youtube.com/watch?v=gdZLi9oWNZg
This video didn't work,
But some of the videos work just fine.

however,
All of the videos didn't work on other test devices.

@NiazSagor

I have attached my full source code.
Please import additional things you need.

If this doesn't work, I'll show you how I debugged it.

@NiazSagor

In my app that I edited, I'm getting reviews from users saying that it doesn't work.
Don't trust my source code.

What I have fixed and what is already existing may have to coexist.

[NiazSagor]

@hhyeok1026 thank you for the code. now what I have faced, some urls are working and some are not.

some of the links that are not working
1WEk-ecKW00
Fmcwap9uwLI

some links that are working
kpmsdqQwNW8

I am confused about how to deal with the problem. How to know for sure which links are going to work and which are not.

The error :
