AVFoundation and AVComposition debugging viewer. Borrowed from Apple sample project and converted to cocoapod. Allows you to create a custom AVMutableComposition and visualize it in the debugger view

To run the example project, clone the repo, and run pod install from the Example directory first.

Works great in Swift or Objective-C:

Just create a custom AVMutableComposition with optional AVMutableVideoComposition and AVMutableAudioMix and pass it to the AVCompositionDebugViewer

import AVCompositionDebugViewer
                    
AVCompositionDebugViewer.showCompositionDebugView(with: avComposition, videoComposition: videoComposition, audioMix: audioMix, containerViewController: viewController)

On Mac: If you pass nil for parameter containerViewController then a new window will popup with the debug view controller automatically.

On iOS: You must specify a containerViewController to contain the composition debug view controller

None. Works on Mac and iOS with AVFoundation
