ActiveVideoView unable to render video stream, but shows profile thumbnail If video is turned off

I am trying to build Custom Meeting UI for zoom meeting. It is integrated into a flutter app which makes use of Zoom Meeting SDK through a plugin. Plugin provides an implementation of a custom UI.
Everything works fine except that the MobileRTCActiveVideoView show only the thumbnail when video of the participant is turned off and remains black if video is switched on.

To Reproduce(If applicable)

protocol CustomMeetingUIViewControllerDelegate: NSObject {
    func userWasAdmittedFromTheWaitingRoom()

class CustomMeetingUIViewController: UIViewController {
    weak var delegate: CustomMeetingUIViewControllerDelegate?
    override func viewDidLoad() {
        if let  localUserID = MobileRTC.shared().getMeetingService()?.myselfUserID() {
            var ideoView = MobileRTCVideoView(frame: self.view.frame)
            var activeVideoView=MobileRTCActiveVideoView(frame: self.view.frame)
            activeVideoView.showAttendeeVideo(withUserID: localUserID)
        view.backgroundColor = .white
extension SwiftFlutterZoomSdkPlugin: CustomMeetingUIViewControllerDelegate {
    func userWasAdmittedFromTheWaitingRoom() {

extension SwiftFlutterZoomSdkPlugin: MobileRTCCustomizedUIMeetingDelegate {
    public func onInitMeetingView() {
        let meetingService = MobileRTC.shared().getMeetingService()
        let customMeetingUIVC = CustomMeetingUIViewController()
        meetingService?.delegate = customMeetingUIVC
        if var topController = UIApplication.shared.keyWindow?.rootViewController  {
            while let presentedViewController = topController.presentedViewController {
                topController = presentedViewController
            topController.present(customMeetingUIVC, animated: true)
            self.customMeetingUIViewController = customMeetingUIVC
    public func onDestroyMeetingView() {

Hi @natansh.m17, thanks for using our SDK.

It looks like you are trying to display the video of the current user, for which you should use MobileRTCPreviewVideoView.
