No video proven with RTCMTLVideoView in WebRTC iOS framework

I’m making an attempt to combine WebRTC Video into my iOS app. I downloaded the framework from https://webrtc.github.io/webrtc-org/native-code/ios/ and constructed it efficiently. Nevertheless, GLView shouldn’t be supported on this codebase, so I had to make use of MetalKit and added RTCMTLVideoView to my class. I additionally added RTCVideoRenderer and RTCVideoViewDelegate and set self.metalVideoView.delegate = self.

When the strategy to deal with incoming video is known as, I can see that the article obtained from the notification is RTC_OBJC_TYPE(RTCMediaStreamTrack): video janusv0 enabled Dwell, and VideoTracks depend is: 1. Nevertheless, I’m not capable of see any video on the display. As a substitute, I simply see a clean display. Within the earlier model of WebRTC, I used GLView with the identical implementation and it labored high-quality.

Are you able to please assessment my implementation under and let me know if I’m lacking something?

    @objc func handleFloorPlanVideoReceived(_ notification: Notification?) {
    if let remoteVideoTrack = notification?.object as? RTCVideoTrack {

        print("Recieved Distant Video: (remoteVideoTrack)")

        DispatchQueue.important.async {
            // Initialize the metalVideoView
            self.metalVideoView = RTCMTLVideoView(body: CGRect.zero)
            self.metalVideoView.delegate = self

            // Add the metalVideoView to the view hierarchy
            self.view.addSubview(self.metalVideoView)
            self.metalVideoView.backgroundColor = .edgeGray
            self.metalVideoView.videoContentMode = .scaleAspectFit

            // Arrange auto structure constraints
            self.metalVideoView.translatesAutoresizingMaskIntoConstraints = false
            NSLayoutConstraint.activate([
                self.metalVideoView.topAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.topAnchor),
                self.metalVideoView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor),
                self.metalVideoView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor),
                self.metalVideoView.heightAnchor.constraint(equalTo: self.view.heightAnchor, multiplier: 1.0/3.0)
            ])

            remoteVideoTrack.add(self.metalVideoView)

            // Create and add the UIActivityIndicatorView
            let activityIndicator = UIActivityIndicatorView(fashion: .giant)
            activityIndicator.colour = .white
            self.metalVideoView.addSubview(activityIndicator)
            self.activityIndicator = activityIndicator

            // Arrange constraints for the exercise indicator
            activityIndicator.translatesAutoresizingMaskIntoConstraints = false
            NSLayoutConstraint.activate([
                activityIndicator.centerXAnchor.constraint(equalTo: self.metalVideoView.centerXAnchor),
                activityIndicator.centerYAnchor.constraint(equalTo: self.metalVideoView.centerYAnchor)
            ])

            activityIndicator.startAnimating()

            // Create and add the shut button
            let closeButton = UIButton(sort: .system)
            if let closeImage = UIImage(systemName: "xmark") {
                closeButton.setImage(closeImage, for: .regular)
            }

            self.metalVideoView.addSubview(closeButton)

            // Arrange constraints for the shut button
            closeButton.translatesAutoresizingMaskIntoConstraints = false
            NSLayoutConstraint.activate([
                closeButton.topAnchor.constraint(equalTo: self.metalVideoView.topAnchor, constant: 8),
                closeButton.trailingAnchor.constraint(equalTo: self.metalVideoView.trailingAnchor, constant: -8)
            ])

            // Add goal for shut button faucet occasion
            closeButton.addTarget(self, motion: #selector(self.closeButtonTapped), for: .touchUpInside)

            self.metalVideoView.setNeedsLayout()
        }
    }
