Preliminary implementation of Python automatic recording screen

Occasionally you need to use Python to implement the recording screen and export the video, write a simple code.

The idea is to take a screenshot at intervals, then turn the screenshot image into a video export.

This is only a test feasibility, no optimization, in fact there is no need for two separate operation, parallel efficiency will be much higher. The use of Time.sleep () is also trickery majority. Wait a while to write a Python version of the Recording screen tool using Wxpython.
