Vuforia Front camera deprecation

Actually I'm working on a unity/vuforia educational project for cultural heritage.
I was using front facing for interactive selfie filters from the project where visitors could take pictures and save on their devices.
After updating unity I did not realized I've upgraded vuforia as well where front facing camera was deprecated. Even downgrading back to the version it was working it is not working anymore. When I switch to front camera the unity app freezes and stop.
Thanks for help!

Failed to set frame format
UnityEngine.Debug:LogError(Object)
Vuforia.CameraDevice:SetFrameFormat(PIXEL_FORMAT, Boolean)
Vuforia.CameraDevice:ForceFrameFormat(PIXEL_FORMAT, Boolean)
Vuforia.CameraDevice:Start()
CameraController:RestartCamera(CameraDirection) (at Assets/Resources/CameraController.cs:37)
CameraController:CameraChange() (at Assets/Resources/CameraController.cs:16)
UnityEngine.EventSystems.EventSystem:Update()

 

This is the c# I'm using to switch to front camera....

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Vuforia;


public class CameraController : MonoBehaviour

{
private bool lightOn = false;
private bool frontCamera = false;

public void CameraChange()
{
if (!frontCamera)
{
RestartCamera(CameraDevice.CameraDirection.CAMERA_FRONT);
frontCamera = true;
Debug.Log("Using Front Camera");
}
else if (frontCamera)
{
RestartCamera(CameraDevice.CameraDirection.CAMERA_BACK);
frontCamera = false;
Debug.Log("Using Back Camera");
}
else
{
Debug.Log("No camera status available.");
}
}

private void RestartCamera(CameraDevice.CameraDirection newDir)
{
CameraDevice.Instance.Stop();
CameraDevice.Instance.Deinit();
CameraDevice.Instance.Init(newDir);
CameraDevice.Instance.Start();

// These are to fight the bug the will otherwise flip the selfie cam upside down on iOS
// Periodically check to see if still needed
VuforiaUnity.OnPause();
VuforiaUnity.OnResume();
}
}



Any clues please?

 

RestartCamera(CameraDevice.CameraDirection.CAMERA_FRONT);
this line not working for update version vuforia 8.3.9 .
main error for CameraDirection var not valid .
plz solution

 

It's a fully removed feature now, sucks for us too. Certain versions of unity still work with older Vuforia versions. I'm here because after upgrading, then subsequently downgrading to 2018.3.5 the camera is now upsidedown...

 

Good day to all!
I’m working on a project where I need to use the front camera and can’t find any information how to switch to it and is there front camera support in the current version? Maybe someone knows how to switch to the front camera for vuforia?

Unity 2018.4.18.f1
Vuforia 8.6.10

 

It's deprecated. Like early in the 8.2 or something.
