There is a bug with the camera using spout mode.
There is a logic missing in judging the camera mode between vertical and horizontal mode while turning spout mode on and off.
- If you turn on spout mode in vertical mode, your camera output will stretch extremely.
- If you turn on spout mode in horizontal mode and turn it off in vertical mode, the camera will change back to horizontal mode without really turning back. It causes a bigger issue if you turn on spout mode again; your camera output will stretch extremely.
The camera will be back to normal if you turn spout mode on and off again in horizontal mode, but it causes a weird problem, which is a hidden change in focal length with no change in UI value.
