如何在Mac OS-X应用程序中显示通过UDP传输的MJPEG流

import Cocoa
import CocoaAsyncSocket
import AVFoundation

class ViewController: UIViewController, GCDAsyncUdpSocketDelegate {
    var udpSocket: GCDAsyncUdpSocket!
    var videoPreviewLayer: AVCaptureVideoPreviewLayer!

    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 初始化UDP Socket
        udpSocket = GCDAsyncUdpSocket(delegate: self, delegateQueue: DispatchQueue.main)
        do {
            try udpSocket.bind(toPort: 8080)
            try udpSocket.beginReceiving()
        } catch {
            print("Failed to bind or start receiving: \(error)")
        }
        
        // 初始化视频预览层
        videoPreviewLayer = AVCaptureVideoPreviewLayer()
        videoPreviewLayer.frame = view.bounds
        view.layer.addSublayer(videoPreviewLayer)
    }

    // UDP Socket接收数据回调
    func udpSocket(_ sock: GCDAsyncUdpSocket, didReceive data: Data, fromAddress address: Data, withFilterContext filterContext: Any?) {
        // 解析MJPEG数据并更新视频预览层
        // 这里省略了具体的解析和渲染逻辑
    }
}
