[BUG 🐛] The managed implementation works on Android, but on iOS, only the bounding boxes are drawn correctly, while the orientation for drawing landmarks is not accurate.

[shishi-RN]

Description: The default bounding box for face detection correctly covers the face on iPad, but the landmarks are positioned outside the face and appear rotated by 90 or 270 degrees.

Steps to Reproduce:

Use react-native-vision-camera-face-detector in a React Native project.
Run the app on an iPad device.
Observe that the bounding box correctly covers the face, but the landmarks are incorrectly positioned and rotated.
Expected Behavior: The landmarks should be positioned correctly inside the bounding box and aligned with the facial features.

Actual Behavior: Landmarks are positioned outside the bounding box and appear rotated (by 90 or 270 degrees).

Environment:

React Native: 0.72.X (or your version)
iPadOS: (version)
react-native-vision-camera: 4.5.0
react-native-vision-camera-face-detector: ^1.7.1
Code Example:

import {StyleSheet, View} from 'react-native';
import React from 'react';
import {Landmarks} from 'react-native-vision-camera-face-detector';
import {Svg, Circle} from 'react-native-svg';

const DrawLandmarks = ({landmarks}) => {
const {
LEFT_CHEEK,
LEFT_EAR,
LEFT_EYE,
MOUTH_BOTTOM,
MOUTH_LEFT,
MOUTH_RIGHT,
NOSE_BASE,
RIGHT_CHEEK,
RIGHT_EAR,
RIGHT_EYE,
} = landmarks;

return (

{Object.values(landmarks).map((point, index) => (

))}

);
};

export default DrawLandmarks;
Additional Information: Any information about the rotation, scaling issues, or other iPad-specific behavior would be helpful.

@luicfrr any updates on this one? Also experienced it

I've also noticed that frame.isMirrored on ios returns true for front camera and false for android. Passing isMirrored={false} to the camera on ios face recognition completely so no face is recognised

Could be connected?

Currently I'm really busy with other projects so I couldn't check this out.
I know there are some "problems" with vision-camera frame orientation and mirroring that I haven't managed to fix yet in my tests.
