WebRTC Swift RemoteStream not Rendering

I have created RTCMTLVideoView throught Outlet.

@IBOutlet weak var otherEndVideoHolderView : RTCMTLVideoView!

And collected RTCMediaStream From the RTCPeerConnectionDelegate Delegate

    func peerConnection(_ peerConnection: RTCPeerConnection, didAdd stream: RTCMediaStream) {
    debugPrint("peerConnection did add stream")

    if let video = stream.videoTracks.first{
        self.remoteVideoTrack = video
        self.delegate?.webRTCClient(self, didReceiveRemoteRender: video)
    }
}

After Offer -> Answer -> and peer status to connected. Only local video is rendering. Remote video is not rendering. enter image description here

Solution

  • I have recently worked on Webrtc and add remote stream on collectionview cell. You can use my code. If you have any other issue let me know, i will help also.

    let stream = VideoCallViewController.arrRemoteStreams[indexPath.row]


    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "RmoteVideoCollectionViewCell", for: indexPath) as! RmoteVideoCollectionViewCell

    cell.contentView.subviews.forEach({ $0.removeFromSuperview() })

    #if arch(arm64)
    // Using metal (arm64 only)
    let remoteRenderer = RTCMTLVideoView(frame:  CGRect.init(x: 0, y: 0, width: 150, height: 150))
    remoteRenderer.videoContentMode = .scaleAspectFit

    #else
    // Using OpenGLES for the rest
    let remoteRenderer = RTCEAGLVideoView(frame:  CGRect.init(x: 0, y: 0, width: 150, height: 150))
    #endif



     //set stream to cell
    stream.videoTracks.first?.add(remoteRenderer)

    //adding stream to cellview
    cell.contentView.addSubview(remoteRenderer)
