MetalVideoProcess is a High-Performance video effects processing framework. It's base on GPUImage3 & Cabbage with AVFoundation, support asynchronous and multithread processing.

Technical requirements

Swift 5.0
Xcode 10.2 or higher on Mac or iOS
iOS: 11.0 or higher
OSX: 10.11 or higher

General architecture

MetalVideoProcess is built on GPUImage3 & Cabbage. We extend the rendering pipeline in gpuimage3 to adapt the rendering output of one to many targets, so as to realize the rendering of multiple video clips.

Getting Started

Compile& import Framework

import MetalVideoProcess

How to use

let asset1 = AVAsset(url: Bundle.main.url(forResource: "test", withExtension: "mp4")!)
let item1 = MetalVideoEditorItem(asset: asset1)

do {
	let editor = try MetalVideoEditor(videoItems: [item1])
	let playerItem = editor.buildPlayerItem()
	let player = try MetalVideoProcessPlayer(playerItem: playerItem)
            
	let beautyFilter1 = MetalVideoProcessBeautyFilter()
  player -- > beautyFilter1 --> renderView
	self.player = player
	self.player?.playerDelegate = self
          
} catch {
	debugPrint("init error")
}
