AttributeError: 'NoneType' object has no attribute 'groups' about unsilence HOT 4 CLOSED

I did a git fetch and reinstall it using pip install --ignore-installed .
but the same message appears in the commandline.
After the issue detected by @AtilioA (thanks!) I tried ffmpeg_version.py from the command line with the following output in the python console:

> >>> import subprocess
> >>> console_output = subprocess.run(
> ...             ["ffmpeg", "-version"],
> ...             stdout=subprocess.PIPE,
> ...             stderr=subprocess.STDOUT,
> ...         ).stdout
> >>> import re
> >>> regex = r"ffmpeg version \D?(\d+(?:\.\d+)*)"
> >>> match = re.search(regex, str(console_output))
> >>> groups = match.groups()
> Traceback (most recent call last):
>   File "<stdin>", line 1, in <module>
> AttributeError: 'NoneType' object has no attribute 'groups'

Recommended downloads of ffmpeg for windows are at https://ffmpeg.zeranoe.com/builds/ and default download is last git version. So, my version is: git-2020-07-16-d11cc74

Solution: I downloadade the lastest release (not git version, 4.3 at the moment) choosing it from the dropdown list top-left and reinstalled it. Now unsilence detects 4.3 version and it working. The output is:

> >>> version = groups[0].split(".")
> >>> print (version)
> ['4', '3']

I have just included this information for other Windows users with the same issues.

Hey, it seems like the ffmpeg version detector does not find a matching ffmpeg version.
Could you check if the ffmpeg version is >4.2.0 and that it is globally available?
If that doesn't fix the problem, could you send me the output of ffmpeg -version?

Thanks,
It's in the PATH (it's working and I checked it).
This is the output (I update it trying to make it work):

@lagmoellertim This has to do with the regex. It doesn't properly parse FFmpeg's string. Now take a look at this one: https://regex101.com/r/lO6pxG/1
I'm using FFmpeg 3.7 and the regex couldn't match it, leading to the NoneType exception.

I'll be opening a PR to fix this.
