vidgear: Wrong validation - ValueError: [WriteGear:ERROR] :: output_filename value:`/Users/*****/Documents/PythonEnv/1.mp4` is not valid/supported in Compression Mode!

Description

The WriteGear is checking for OS folder access and failing the process for no good reason, after bypassing the check all is working as expected.

Acknowledgment

I have searched the issues for my issue and found nothing related or helpful.
I have read the Documentation.
I have read the Issue Guidelines.

Environment

VidGear 0.2.0 Branch: PyPi Python 3.9.1 Pip 20.3.4 OS: Mac 10.14.6

Expected Behavior

The local video file should rendered/created using FFMPEG.

Actual Behavior

I got the following error (logging is True):

Output file: /Users/*****/Documents/PythonEnv/1.mp4 15:46:25 :: WriteGear :: WARNING :: The given path:/Users/******/Documents/PythonEnv/1.mp4 does not have write access permission.

Possible Fix

In WriteGear.py: Line 126 : I changed: if ( self.__os_windows or os.access in os.supports_effective_ids ) and os.access(os.path.dirname(abs_path), os.W_OK): To if(True) and it all worked. Meaning the if expression is not working properly. My guess is that it is different on a PC vs Mac or that the Virtual Environment is impacting this ‘if’

Steps to reproduce

(Write your steps here:)

Download gyroFlow and all dependencies (VidGear included)
Run Venv (Python Virtual Environment) with all the dependencies
Try to stabilize a video

Thank you so much for the quick fix!

Good point, didn’t check - Let me try.

nivim on Jan 24, 2021

Documents folder is indeed present, and as I wrote in the ultra detailed bug openning doc 😉 - Mac 10.14.6

Do you want me to try and see which part of the If statement fails in WriteGear.py?

nivim on Jan 24, 2021

I can share with you the logging of it failing as well if it helps
