Alright friends welcome back, lets make a very flexible screen recorder today. The target platform for this GUI is Windows 10. For direct installation to windows 10, please download these three parts in a folder and then extract (using winRAR) the PyShine Recorder setup.zip file:
IMPORTANT
Please run the code below only from PowerShell and not use any IDE, such as PyCharm or others, because it will not work in them properly. Copy the code below in a Python file as main.py and save it to a location. Then go to that location open up the Windows PowerShell as Shift+ Right click “open PowerShell window here” then run it as:
python3 main.py
main.py
