VideoCast-Swift

VideoCast-Swift is a framework for broadcasting live video. It is based on VideoCore C++ library but rewritten in Swift. It currently works with iOS. It is a work in progress and will eventually expand to other platforms such as OS X.

Setup

CocoaPods

Create a Podfile with the contents

platform :ios, '8.0'
pod 'VideoCast', '~> 0.1.0'
use_frameworks!

Next, run pod install and open the xcworkspace file that is created.

Architecture Overview

Samples start at the source, are passed through a series of transforms, and end up at the output.

e.g. Source (Camera) -> Transform (Composite) -> Transform (H.264 Encode) -> Transform (RTMP Packetize) -> Output (RTMP)
