无法使用TwilioVideo（iOS）设置全屏以进行远程视频查看

Question

I am using Twilio for Video calling and its working fine but the only issue is unable to set the full screen for remote video. Its showing vertically full but not horizontally, after searching in Twilio video docs I found the below snippet apparently not working.

let videoConstraints = TVIVideoConstraints { (constraints) in
constraints.maxSize = TVIVideoConstraintsSize960x540;
constraints.minSize = TVIVideoConstraintsSize960x540;
constraints.maxFrameRate = TVIVideoConstraintsFrameRateNone;
constraints.minFrameRate = TVIVideoConstraintsFrameRateNone;

camera = TVICameraCapturer(source: .frontCamera, delegate: self)
    localVideoTrack = TVILocalVideoTrack.init(capturer: camera!,
                                              enabled: true,
                                              constraints: videoConstraints)

Its throwing the below exception, Help me in this

"Error: Failed to create a video track using the local camera."

Video call is for iPhone SE, 6, 6s, 7 form factors

I just noticed that while the documentation does tell you to implement the constraints via TVILocalVideoTrack.init the specific iOS documentation says not to use the init method.

Have you tried trackWithCapturer:enabled:constraints instead?

TVILocalVideoTrack.trackWithCapturer(camera!, enabled: true, constraints: videoConstraints)
