Can't find file with ffmpeg.input()

See original GitHub issue

import ffmpeg
import os

file1 = 'input.avi'
file2 = 'output.avi'
print(os.path.isfile(file1))   #True

stream = ffmpeg.input(file1)
stream = ffmpeg.hflip(stream)
stream = ffmpeg.output(stream, file2)
print(stream.get_args())
ffmpeg.run(stream)   #FileNotFoundError: [WinError 2] The system could not find the specified file.

Here is the print:

True
['-i', 'input.avi', '-filter_complex', '[0]hflip[s0]', '-map', '[s0]', 'output.avi']
---------------------------------------------------------------------------
FileNotFoundError                         Traceback (most recent call last)

Make sure ffmpeg is installed and on your system path. Note that ffmpeg-python does not try to automatically install ffmpeg. It’s simply a python wrapper for ffmpeg, and it’s up to you to make sure it’s installed in whatever way makes sense for how you’re using it.
