Failed to extract information of some specific videos. It seems that the most suspicious part is the music-related video.

The ciphered video is not working.
(Mainly copyrighted official music channels)

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

What I've been debugging.

CipherManager class -> public static String getDecipherCode(String Basejs) method in

This line is the problem.
String RawName=RegexUtils.matchGroup(RegexVarName, DecipherFun).replace("$","\\$");
RegexUtils.matchGroup(RegexVarName, DecipherFun) => This is a null value.

The reason is that the DecipherFun value of the line above it is strange.
String DecipherFun => value : "decipher=function(a)null".

As a result,
RegexDesipherFunctionCode does not work.
so,
RegexVarName also doesn't work.

The cause is
private static String getPlayerCode(String playerUrl) throws IOException
The structure has changed in the page fetched from the method.

It is now confirmed to be working again.

It looks like YouTube has turned it back.

However, it can also cause problems,
so,
I've found a more stable library
I am applying that library to my project.
https://github.com/yausername/youtubedl-android
It is a library that wraps the most famous ytdl written in python.

I just confirmed that it works.
As I said, I am anxious because I don't know when it will fail again in the future.
Let's check the library you informed.
Thank you for your continued interest :)

When an error occurs, there is a fixed content of the library where the same error occurred as we did.

If we check the library's modifications, it looks like we'll get some hints on points to fix.

but,
Currently I can't test it.
Now that it’s working well with the existing source,

Thanks for the information. If it doesn't work again next time, I will try to debug that part.
