Parsing-Error when probing wav-files

[atoav]

It seems, probing wav files (or other files that don't have a video stream) seems to not work. I tried the same with a mov file and it worked like a charm.

File "C:\Users\MYUSER\AppData\Local\pypoetry\Cache\virtualenvs\MYPROJECT-R5fSZ7UV-py3.8\lib\site-packages\ffprobe\ffprobe.py", line 75, in __init__
    self.metadata[m.groups()[0]] = m.groups()[1].strip()
AttributeError: 'NoneType' object has no attribute 'groups'
