IISC your problem is that you want to access the variable link defined in streams in the conversation state CLICK_FORMAT/ in the callback click_format.

As the update variable in the click_format contains information about the button click and not about the previously sent message, you'll have to store the link in a variable that click_format can access. You could naively use a global variable for that, but that has multiple downsides. Most notable, this will not work well when multiple users try to user your bot at the same time.

However, PTB comes with a bulit-in mechanism just for that: context.user_data is a dictionary where you can store information associated to that user. So you could store the link as e.g. context.user_data['link'] = link and the access it in click_format as link = context.user_data['link'].

Please see the wiki page for an explanation of user_data with example and also see conversationbot.py example, where this feature is used in conjunction with a ConversationHandler.

The WindowsError you see does not refer to the video file but to the ffmpeg executable itself. The call to subprocess.call has no idea that File.mp4 is a filename you are passing. Windows knows that the first parameter ought to be an executable file and reports back to the interpreter that it can't find it.

Double-check that ffmpeg can be executed in the environment your interpreter is running in. You may either add it to your PATH or specify the full path to ffmpeg.exe.

It seems that your build.gradle file contains a splits block.

Please read this for more information.

[EDIT]

As i 've told you above your build.gradle file seems to contains a splits block. So here it is

It has nothing to do with "_" or "-". "n85KukOXc0A" doesn't work either. Some videos don't return the "url" field, but "cipher". It's an attempt from YouTube to obfuscate the URL.

Your $videoDownloadLink, for the video ID "wXhTHyIgQ_U", looks like:

1. Your code never seems to be using self.user_music, so, based on the code snippet you provided, you don't need to define it. If you are not passing anything to __init__, and don't need to do any custom initialization during object instantiation, you don't need to define a constructor (__init__) because Python will provide a default constructor for you.
2. Names defined inside a function belong to the function's local scope and are not visible outside of that scope. If you want to use the value of subject, you need to pass it as an argument to all other functions or methods that might want to use it. You can turn it into an instance attribute: self.subject = 'whatever', and use it when needed; in such case, you don't need to pass it around.

Please note that the answers are based on the current code snippet. We don't see how you use searchYoutube or downloadVideo, so the final answer might be different.

EDIT: Updating the code as per the request in comments to show how to create an instance variable subject.

the t1 = threading.Thread(l,target= line is not consistent with t2 and t3

the extra l was wrongly taken as the default value for group arg

typo?

First off you have a small typo you should fix that is unrelated to your error. The first parameter is part valid values are

1. contentDetails: 2
2. id: 0
3. snippet: 2

You have snipper

It isn't clear that this is the issue as the error you are getting isn't related to the API.

The issue sounds more like a problem with the dll. I would try to reimport the nuget package make sure you are using.net 4.5 in your project

I fixed the npmjs.com/package/youtube-dl issue by download the latest youtube-dl exe from https://youtube-dl.org/downloads/latest/youtube-dl.exe, then putting it in node_modules\youtube-dl\bin
