Video stabilization using VidStab and FFMPEG

** Step 1 **

Install ffmpeg with the vidstab plugin.

OSX: Install via Homebrew - brew install ffmpeg --with-libvidstab
Linux: download binaries here (vidstab included)
Windows: download binaries here (vidstab included)

OAUTH2

The Problem

I’m a web app that wants to allow other web apps access to my users’ information, but I want to ensure that the user says it’s ok.

The Solution

I can’t trust the other web apps, so I must interact with my users directly. I’ll let them know that the other app is trying to get their info, and ask whether they want to grant that permission. Oauth defines a way to initiate that permission verification from the other app’s site so that the user experience is smooth. If the user grants permission, I issue an AuthToken to the other app which it can use to make requests for that user's info.

Note on encryption

Oauth2 has nothing to do with encryption -- it relies upon SSL to keep things (like the client app’s shared_secret) secure.

	//Moebius transformations in 3d, by reverse stereographic projection to the 3-sphere,
	//rotation in 4d space, and projection back.
	//by Daniel Piker 09/08/20
	//Feel free to use, adapt and reshare. I'd appreciate a mention if you post something using this.
	//You can also now find this transformation as a component in Grasshopper/Rhino
	//I first wrote about these transformations here:
	//https://spacesymmetrystructure.wordpress.com/2008/12/11/4-dimensional-rotations/

	//If you want to transform about a given circle. Points on the circle and its axis stay on those curves.
	//You can skip these 2 lines if you want to always use the origin centred unit circle.
