Doesn't work with ytmusicapi==1.x.x and pytube==15.x.x

[cprn]

Both ytmusicapi and pytube got updated beyond of what version 0.3.8 works with so the workaround is to install older versions instead:

pip uninstall ytmusicapi
pip install ytmusicapi==0.25.0
pip install pytube==12.1.2

(then restart mopidy)

[cprn]

Maybe this should be in README.md for the time being?

[herkow]

Check this https://github.com/pytube/pytube/pull/1691

I've been searching the web for two days, but finally found the solution.

Rename your actual cipher.py to cipher.py.old o whatever. Create a new file named cipher.py, and paste the code from the last fixed cipher.py on git https://github.com/yogeshgirmal/pytube/blob/b0c9de965f7ec8b3140cc5a5a9eb15c039a5bd79/pytube/cipher.py

Restart mopidy, done.

@herkow this needs one more patch now: https://github.com/pytube/pytube/pull/1756

Upd: still doesn't work for me. Some other people report that the fix doesn't work for them too.

[herkow]

@selurvedu Today I tried to play some music and it didn't work. Official Pytube cipher.py has not been modified in about a year. I could spend weeks ranting about python... The solution that worked for me is in this repo https://github.com/yogeshgirmal/pytube/tree/b0c9de965f7ec8b3140cc5a5a9eb15c039a5bd79/pytube wich is not offcial. Today it was NOT working. But I've modified the line:

var_regex = re.compile(r"^\w+\W")

to

var_regex = re.compile(r"^\$*\w+\W")

and now it's working. Make sure you are using the cipher.py from the yogeshgirmal repo, not the official.

[selurvedu]

@herkow that's exactly what I did. Just tried it again and still getting pytube.exceptions.RegexMatchError: get_throttling_function_name: could not find match for multiple. I checked if I'm editing the right file – I do.

Let's give it a last shot... rename your actual cipher.py to whatever you like, create a new one and paste this:

"""
This module contains all logic necessary to decipher the signature.

YouTube's strategy to restrict downloading videos is to send a ciphered version
of the signature to the client, along with the decryption algorithm obfuscated
in JavaScript. For the clients to play the videos, JavaScript must take the
ciphered version, cycle it through a series of "transform functions," and then
signs the media URL with the output.

This module is responsible for (1) finding and extracting those "transform
functions" (2) maps them to Python equivalents and (3) taking the ciphered
signature and decoding it.

I just want to say I tested it and it still works without issues on up to date Ubuntu with the workaround I mentioned in the first post. Although I have same issues as everyone on Arch / Manjaro so it'd be beneficial if this PR got accepted.

[herkow]

Something strange is happening now. When I "sing-in" to my account via the auth_json file, I can not play (and can not search) any tracks. But when Youtube de-authorizes me, I can search and play.

Is this happening to you to?

@herkow Sorry for late response. I switched to jmcdo29's fork of this repository. As soon as @jmcdo29 accepts my PR his fork will be working out of the box - it's already used by Arch user repo package.

edit: the PR got accepted, jmcdo29's repo is the most current one right now

ytmusic/oauth_json config key not found.

You need oauth_json in your mopidy [ytmusic] section with a path to where you want to keep the oauth.json file as there's no default location for it, e.g.:

[ytmusic]
oauth_json = /home/herkow/.config/mopidy/oauth.json

Run setup after you add it, it should work - it worked for me when I made that change.

Well, I've been trying to solve this, and cloned the repo (which says v0.3.9) just in case git+ is doing something crazy... But when I check the installed version, still shows 0.3.8... Last shot was to copy the old auth.json to oauth.json and now YTMusic appears in the client but is not possible to search, I can only access to YTMUSIC lists (mosts palyed, best of my country, etc.) There is no way to excute ytmusic setup and of course is not possible to reauth.

Any ideas?

BTW, I'm using Debian 12.

More workaround here, and now I've switched to ytmusicapi 0.25.0. I can search and play, but still can't setup, and the reauth is missing something, since it never asks for the credentials:

@herkow I have no idea what you've done but you definitely had some mismatch in your installed packages because this:

ImportError: cannot import name 'setup_oauth' from 'ytmusicapi.setup' (/usr/local/lib/python3.11/dist-packages/ytmusicapi/setup.py)

says you don't have setup_oauth function in the linked file and it should be there in the current version.

I see you've managed to fix that part and the function imports and calls but on my setup it opens the default browser (or at least displays the URL to open in the browser manually) to login to YT, however, I'm not using sudo or mopidyctl or global configs in /etc so maybe it's that. AFAICT it's working fine on my Manjaro/Arch setup out of the box. Since you don't have any further errors displayed I'd suggest to install all dependencies from scratch, make sure they're the newest versions, and try to debug the code. It should work OK as long as this line is called:

    return RefreshingToken.prompt_for_token(oauth_credentials, open_browser, filepath)
