How to use iPhone's different back cameras (WideAngle/Telephoto/UltraWide) for the capture while publishing the video?

[gabanivishal]

I am using the video sdk for video chat for iOS Devices.

I was trying to find a method to use various iPhone's back cameras (WideAngle/Telephoto/UltraWide) while publishing the video. I do not find any method in which I can specify the camera and use it for video capture. It will be very helpful if someone can point to correct method/documentation.

I had the same issue and I've found out you can do that by implementing yourself the OTVideoCapture for the OTPublisher, but you have to code it all by yourself... Have fun!
