HTTP Live Streaming Tutorial

Note: This is an older post that I did back when I thought I might have time to be a blogger. Oh I was oh so wrong. However, it has proven useful for some folks on stackoverflow. Thus I'm keeping it alive here on Gist.

One of my past projects dealt heavily with an open source Apple technology called HTTP Live Streaming. It’s an HTTP based streaming protocol that at its most fundamental level provides a way to stream video and audio from just about any server with nothing but a few free software tools provided by Apple**. However, it has a few additional features that I think make it a really exciting tool. Yet, I haven’t seen HTTP Live Streaming used very much. This is probably mainly due to the combination of a lack of good/clear documentation, and Apple’s Live Streaming Developer Tools being command line based also make the barrier to entry higher than many developers want to deal with.

The hope is to share my understanding of how to use this technology to:

iOS Core Animation: Advanced Techniques, Part 1: The Layer Beneath

Author: https://www.cyanhall.com/

1. The Layer Tree

Core Animation's original name is Layer Kit

Core Animation is a compositing engine; its job is to compose different pieces of visual content on the screen, and to do so as fast as possible. The content in question is divided into individual layers stored in a hierarchy known as the layer tree. This tree forms the underpinning for all of UIKit, and for everything that you see on the screen in an iOS application.

In UIView, tasks such as rendering, layout and animation are all managed by a Core Animation class called CALayer. The only major feature of UIView that isn’t handled by CALayer is user interaction.

There are four hierarchies, each performing a different role:
