// The stream id for your viewers. Populate this to the devices that want to join.
if let stream = self.stream {
print(stream.id)
print(stream.getPlaybackUrl()?.absoluteString ?? "Error retrieving stream URL")
}
}
}
}

Use the Example#

Just instantiate the LiveCameraHostViewController with the corresponding streaming type and it will start a full screen camera broadcast.

let streamVC = LiveCameraHostViewController(streamType: .lowLatency)
self.navigationController?.pushViewController(streamVC, animated: true)
