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

• Swift 5.0

• Xcode 10.2 or higher on Mac or iOS

• iOS: 11.0 or higher

• OSX: 10.11 or higher

• Realtime smooth playback with filters
• Support two video transitions
• Support video motions
• Video picture in picture
• Transform video with multitouch
• Support export video with H.265
• Support video split, delete, insert, merge
• High performance metal rendering

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.
