Could not find match for config_patterns for certain urls

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 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?

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, 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\(\{'PLAYER_CONFIG':\s*({.*})(,'EXPERIMENT_FLAGS'|;)", # noqa: E501 r"'PLAYER_CONFIG':\s*({.*})}\);", ]
