Hi,
I'm using Vuforia as a complement for my application on Unity 4.5.5f1. The vuforia's part is only a module the user can enable/disable. I need to activate and deactivate Vuforia from time to time.
I've been able to put the ARCamera prefab into the scene and activate/deactivate the gameObject in order to get the camera stream when needed.
In my specific case, I need to use the front camera (with mirror image ON), and use NGUI at the same time.
I first tried to implement my module using the Vuforia SDK 4.0.103. I had the camera image as I wanted, but also had an issue with NGUI (similar to https://developer.vuforia.com/forum/issues-and-bugs/vuforia-40-messed-overlay-ui).
Now I'm using Vuforia SDK 4.2.3, I don't have any issue with NGUI anymore, but the "mirror image" for the Camera Front doesn't work at the first launch.
- Step 1 : Enable ARCamera prefab (set on CAMERA_FRONT, and mirror image ON) : Camera image is upside down
- Step 2 : Disable ARCamera prefab
- Step 3 : Enable ARCamera prefab : Camera image is normal
Tested on :
- Samsung Galaxy Note 3 / Android 4.4.2
- Samsung Galaxy S3 / Android 4.4.4
- Note : I've tested on a Google Nexus 4 / Android 5.1 too but it's less stable. I have sometimes the stream frozen, sometimes not.
Is there something that I missed or is it a bug from SDK 4.2.3 ?
Thank you for your help.
- Development OS (Mac OS X, Windows, Linux): Windows - Mobile OS and Version: Android 4.4.2 - Mobile Device Manufacturer and Model name: Samsung Galaxy Note 3 - Do the Vuforia Sample Applications show the same behavior?: Tested the UserDefinedTargets sample. I changed to Camera Front, and both mirror image ON and OFF result to an upside down image.

Thanks for the report.
We were able to reproduce this same issue with the following steps:
- Create an empty Unity project and import the Vuforia Unity Extension 4.2.3
- Add an ARCamera to the scene
- Select Camera Direction = FRONT
