Could not find match for config_patterns for certain urls

[lukas4haus]

Hi,
I started using pyTube just recently and I am very happy with the functionality.
I am using it to download music tracks from YouTube Music.

In most of my tests, it worked great, but with some urls I catch an exception:

pytube.exceptions.RegexMatchError: get_ytplayer_config: could not find match for config_patterns

For example it occurs with this track: https://www.youtube.com/watch?v=hbFQARBbZww

I am neither good at regex, nor do I really understand what to search for in the analyzed html.
Do you maybe have a solution for this issue, or can you give me some hints about how to fix the issue myself?

Best regards,
Lukas

Hi, I spent an hour on it but found a solution, specially set up an account here to share it.
In the pytube/extract.py file, add to the config_patterns list
r"'PLAYER_CONFIG':\s*({.*})});"
it's supposed to look like this
config_patterns = [ r";ytplayer\.config\s*=\s*({.*?});", r";ytplayer\.config\s*=\s*({.+?});ytplayer", r";yt\.setConfig\(\{'PLAYER_CONFIG':\s*({.*})}\);", r";yt\.setConfig\(\{'PLAYER_CONFIG':\s*({.*})(,'EXPERIMENT_FLAGS'|;)", # noqa: E501 r"'PLAYER_CONFIG':\s*({.*})}\);", ]

Hi sirodus,
I tried both versions mentioned in your comment, but both were unsuccessful.

r"'PLAYER_CONFIG':\s*({.*})});"
r"'PLAYER_CONFIG':\s*({.*})}\);"

Could you please check if there is a typo or something in your comment if you were successful using the regex?

Html source code:

from video that works:

One of the links has a Watermark in it's source code.

This is definitely correct. In your case, you may need to add other expression to the config_patterns list. Send me the link of the video you still have problems with after adding my fix.

works for me

I am sorry, but it is still the URL from my first message which is causing me issues.

Now I realized that all the urls that are working for me are not YouTube Premium only, but available for everyone
e.g https://www.youtube.com/watch?v=UGN00k2bHgs

The one in the start post is indeed premium only (in Germany). I can also not access it from a private tab in my browser. As I can not find a way to provide my credentials to pytube, this might be a dead end for me.

Thank you for your support!

I modified the file "extract.py" in line 187 with the following (keep attention to open-close variables):

config_patterns = [
    r";ytplayer\.config\s*=\s*({.*?});",
    r";ytplayer\.config\s*=\s*({.+?});ytplayer",
    r";yt\.setConfig\(\{'PLAYER_CONFIG':\s*({.*})}\);",
    r";yt\.setConfig\(\{'PLAYER_CONFIG':\s*({.*})(,'EXPERIMENT_FLAGS'|;)",  # noqa: E501
r"'{PLAYER_CONFIG':\s*({.*})});" ]

and works like a charm!!!.

Hi @lukas4haus I believe the most recent update to the repository should fix the issue with these videos (though it can't fix premium-only videos). If you want to test it out, you can install from the source with python -m pip install git+https://github.com/nficano/pytube. Let me know if this works!
