[BUG] RegexMatchError: get_throttling_function_name: could not find match for multiple - v15.0.0 #1954

howsinapp · 2024-07-09T12:47:41Z

I have confirmed that I am on the latest version of pytube by installing from the source. 15.0.0

Since today I'm encountering a RegexMatchError when trying to download a YouTube video using pytube. The error message suggests that the function get_throttling_function_name could not find a match for multiple. Occurs sometimes, not for all video.

To Reproduce
https://www.youtube.com/watch?v=aDEDfbN5gIU
stream = yt.streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first()

Expected behavior
I expected the video to be downloaded without any errors.

Output
File "/usr/local/lib/python3.11/site-packages/pytube/main.py", line 296, in streams
return StreamQuery(self.fmt_streams)

i encounter the exact same issue. After asking for help to chat-GPT it seems like youtube updated their javascript

garmanarnaryt · 2024-07-09T16:41:52Z

reported the same on the pytube3 as well. but seems like this is more maintained?

they updated for sure. :/

any workaround for cipher.py and other modules that uses the regex:js?

ysawyers · 2024-07-09T16:58:50Z

runnning into the same issue too currently!

chang432 · 2024-07-09T16:59:25Z

I see the same error as well

artemdashkov · 2024-07-09T17:23:12Z

have the same problem too. Python 3.12.4, pytube 15.0.0.

how did you get to the solution? did you debug the js? Im curious how you work out to add another line of function_patterns string?

@garmanarnaryt I remembered when that regex was replaced the last time this happened, so I figured I'd just try putting it back and see what happens.

thank you. i confirm that it works now.

I'm just curious on how to solve this kind of issue in the future. I tried to print out the "js" value on my own an try to understand the code. why the regex dont understand the current yt "js"

Change cipher.py at line 264
If you don't understand it, it's better to wait for distribution.

you need change code at line 264 in file .venv/Lib/site-packages/pytube/cipher.py, where ".venv" name of folder python virtual environment. when you find file you will understand what need to change

Thanks, it works now with python 3 and pytube 15,
The question I have is when will they update that in a new version? Imagine that I am passing the script to another user, the user installs it with pip install pytube and it will not work because he has to get his hands on cipher.py

still prefer pytube, but before above bug is fixed, I am going to use yt-dlp as a backup, see this thread https://www.reddit.com/r/Python/comments/18wzsg8/good_pytube_alternative/

I tried it out, which worked. it offers 2 features I like

extract audio only format,
my main usage is to listen music offline, so this feature would save storage too.
specify video_id instead of URL.
This CLI tool has tons of options, need to read documentation to get used to

To get started quickly, do the following (3ug835LFixU is the YT video_id as an example)

pip install yt-dlp
yt-dlp -x --audio-format mp3 3ug835LFixU

I have confirmed that I am on the latest version of pytube by installing from the source. 15.0.0

Since today I'm encountering a RegexMatchError when trying to download a YouTube video using pytube. The error message suggests that the function get_throttling_function_name could not find a match for multiple. Occurs sometimes, not for all video.

To Reproduce https://www.youtube.com/watch?v=aDEDfbN5gIU stream = yt.streams.filter(progressive=True, file_extension='mp4').order_by('resolution').desc().first()

Expected behavior I expected the video to be downloaded without any errors.

Output File "/usr/local/lib/python3.11/site-packages/pytube/main.py", line 296, in streams return StreamQuery(self.fmt_streams) ^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/pytube/main.py", line 188, in fmt_streams extract.apply_signature(stream_manifest, self.vid_info, self.js) File "/usr/local/lib/python3.11/site-packages/pytube/extract.py", line 409, in apply_signature cipher = Cipher(js=js) ^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/pytube/cipher.py", line 43, in init self.throttling_plan = get_throttling_plan(js) ^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/pytube/cipher.py", line 405, in get_throttling_plan raw_code = get_throttling_function_code(js) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/pytube/cipher.py", line 311, in get_throttling_function_code name = re.escape(get_throttling_function_name(js)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/pytube/cipher.py", line 296, in get_throttling_function_name raise RegexMatchError(pytube.exceptions.RegexMatchError: get_throttling_function_name: could not find match for multiple

System information

Python version 3.11

Pytube version 15.0.0

pip install pytube

For me this worked:
I had to change line 195 of the "/usr/local/lib/python3.9/dist-packages/pytube/cipher.py" file from

pattern = r"%s=function\(\w\){[a-z=\.\(\"\)]*;(.*);(?:.+)}" % name

To

pattern = r"%s=function\(\w\){[a-z=\.\(\"\)]*;((\w+\.\w+\([\w\"\'\[\]\(\)\.\,\s]*\);)+)(?:.+)}" % name

And also line 264 to

r'a\.[a-zA-Z]\s*&&\s*\([a-z]\s*=\s*a\.get\("n"\)\)\s*&&.*?\|\|\s*([a-z]+)',
r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])?\([a-z]\)',
r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])\([a-z]\)',

vhngroup · 2024-08-13T04:16:55Z

Windows:
Unzip and replace file cipher.py in:
C:\Users\ YourNameUser \AppData\Local\Programs\Python\Python312\Lib\site-packages\pytube
cipher.zip

or in your folder python into folder Lib in site-packages\pytube in a array "function_patterns" add:
r'a.[a-zA-Z]\s*&&\s*([a-z]\s*=\sa.get("n"))\s&&.?||\s([a-z]+)',

r'([a-z]\s*=\s*([a-zA-Z0-9$]+)([\d+])([a-z])',

Bye Solved

I have confirmed that I am on the latest version of pytube by installing from the source. 15.0.0 Since today I'm encountering a RegexMatchError when trying to download a YouTube video using pytube.

Change the function_patterns array in cipher.py at line 264 to include this one and it seems to work:

function_patterns = [
    # https://github.com/ytdl-org/youtube-dl/issues/29326#issuecomment-865985377
    # https://github.com/yt-dlp/yt-dlp/commit/48416bc4a8f1d5ff07d5977659cb8ece7640dcd8
    # var Bpa = [iha];
    # ...
    # a.C && (b = a.get("n")) && (b = Bpa[0](b), a.set("n", b),
    # Bpa.length || iha("")) }};
    # In the above case, `iha` is the relevant function name
    r'a\.[a-zA-Z]\s*&&\s*\([a-z]\s*=\s*a\.get\("n"\)\)\s*&&.*?\|\|\s*([a-z]+)',
    r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])?\([a-z]\)',
    r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])\([a-z]\)',
]

Does anyone know how we're getting the patterns? I'd love to see if we can add in a dynamic fix

Hi! I tried this (05/10/2024) but it didn't work. This could be an error with me incorectly doing it. When I replace lines 264 - 274 with the above text, bringing it to line 275, in the file C:\Users\[user]\AppData\Local\Programs\Python\Python312\Lib\site-packages\pytube\cipher.py. I saved the file and retried my program but now it spits this error:

Exception has occurred: TypeError
'StreamQuery' object is not callable
  File "C:\Users\[user]\Coding Adventures\Google Download Test.py", line 8, in <module>
    print(pytube.YouTube(url).streams().get_highest_resolution())
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: 'StreamQuery' object is not callable

Heres the script I'm working on:

url = "https://www.youtube.com/watch?v=eH4F1Tdb040"
print(pytube.YouTube(url).streams().get_highest_resolution())
