Hey @criva,

Thanks for using the dev forum!

Are you using a custom meeting UI or the default meeting UI?

Thanks!

Hi

I am using custom meeting UI

Hey @criva,

Can you provide your code for showing the attendee video views?

Thanks!

I using the following class

//--------
class AttendeeVideoView : UIView {

public var userId: UInt? = nil

override init(frame: CGRect) {
  super.init(frame: frame)
  setupView()
}

lazy var videoView : MobileRTCVideoView = {
    let _videoView = MobileRTCVideoView.init(frame: self.bounds)
    if let userId = userId {
        _videoView.showAttendeeVideo(withUserID: userId)
        _videoView.setVideoAspect(MobileRTCVideoAspect_PanAndScan)
    }
    return _videoView
}()

private func setupView() {
    self.backgroundColor = UIColor.black
    self.addSubview(self.videoView)
}

func updateFrame() {
    self.videoView.frame = CGRect(x: 0, y: 0, width: self.bounds.size.width, height: self.bounds.size.height)
}

func showAttendeeVideo(userId: UInt) {
    if self.userId != nil && self.userId == userId {
        return;
    }
    self.userId = userId
    videoView.isHidden = false
    videoView.showAttendeeVideo(withUserID: userId)
    videoView.setVideoAspect(MobileRTCVideoAspect_PanAndScan)
}

func stopAttendeeVideo() {
    videoView.stopAttendeeVideo()
    videoView.isHidden = true
    userId = nil
}

}
//----------

Externally I call “showAttendeeVideo” passing the userId and “stopAttendeeVideo” for start and stop video. “updateFrame” is called when the AttendeeVideoView has been resized.

Hey @criva,

That is very interesting. I am curious if the video stream starts at a place in the view’s lifecycle where the orientation may not be known? Can you reproduce this on that device, then email the SDK logs to developersupport@zoom.us? Please provide a link to this post and mention my name.

Thanks!
Michael

Unfortunately, it’s not that easy

The problem does not occur on a development device (but on a customer device). I don’t own this specific iPad model.

… and the simulators are not helping me in any way for debugging these kinds of camera issues.

Hey @criva,

I understand, I also do not have this specific model. Normally we cannot investigate an issue that is specific to one device without being able to reproduce or without being able to inspect the logs. However, I will inform the engineers about this and see if there is some other way we can troubleshoot :slight_smile:

Thanks!
Michael
