I've just installed ffpb and this dropped. Any solutions?

Do you have ffmpeg installed and available in your PATH?

Do you have ffmpeg installed and available in your PATH?

>>> from os import *
>>>
>>> # for variable in PATH
>>> #    if lowercase variable ends with ffmpeg.exe
>>> #        print(variable)
>>>
>>> for Variable in environ["PATH"].split(pathsep):
...     if Variable.lower().endswith("ffmpeg.exe"):
...         print(Variable)
...
C:\Users\kubinka0505\Programs\ffmpeg.exe

TLDR: Yes

If that's important I use:

ffmpeg version 4.2.2 Copyright (c) 2000-2019 the FFmpeg developers
built with gcc 9.2.1 (GCC) 20200122
...

I did some tweaking, and I've figured out that ffpb works only if FFmpeg is in the user's home directory.

It's likely that the error is caused by inaccurate path detection of the static FFmpeg executable binary, which is probably performed on this line:

ffpb/ffpb.py

Line 155 in da41f96

cmd = ["ffmpeg"] + argv

I recommend applying some kind of universal detection function like this:

from pathlib import Path

def Detect_Binary(Name: str.lower, Variable_Name: str = "PATH", Format: str = "EXE") -> str:
	"""Looks for binary of `Name` in the `Variable` environment variable."""
	Name_Original = Name
	Name = Name.lower()
	Format = Format.lower()
	#-=-=-=-#
	if os.sys.platform.lower().startswith("win"):
		for Variable in os.environ[Variable_Name].split(os.pathsep):
			if Name + "." + Format in Variable:
				# Fix the final path
				Name = str(Path(Variable).resolve())
				if not os.path.exists(Name):
					raise AttributeError(Name_Original + " not found!")
	#-=-=-=-#
	return Name

...and then

...
cmd = [Detect_Binary("FFmpeg")] + argv
...

That's weird, on my Windows machine ffpb works even with ffmpeg installed somewhere in C:\\...
