WIP Post for Creating Native Installer PyQt application

# Building a PyQt5/PySide2 macOS Application

## Preface

As part of my professional duties, I have been tasked with developing a desktop application to analyze audio files. This desktop application would need to be work across platforms (Windows, macOS and Ubuntu), and I cannot rely on dependencies having already been installed (such as Python itself). Naturally I turned to Qt (and more specifically, Qt for Python) due to its capabilities for creating GUI applications that work across OSs. As I could not be dependent on the end user having Python installed (so no deploying a wheel and calling it good), I decided it may be worth trying to make native installers (`deb` packages for linux, `.app` bundles and `.dmg` files for macOS, and `setup.exe` files for Windows).

In short, here were the objectives I aimed to have

• Cross-Platform compatible GUI application
• Deployment to users via native installers (no assumption of python being on the target machine)

Short summary of ffmpeg usage

# FFmpeg Walkthrough

## basics

`ffmpeg` is a command line utility that presents a API to interacting with a variety of media types/encodings in a uniform fashion.

Depending on the `ffmpeg` distribiont, you may get access to utilities such as `ffprobe` (which provides information on a file) and `ffplay` (will play back a file). Those tools are critical.

Those tools, by default, will show all the arguments that `ffmpeg` was compiled with, which can get a little verbose. If you're going to run many ffmpeg commands, I suggest you get used to passing the `-hide_banner` argument.
