I am trying to get the AR/VR Sample working with Vuforia 5.0.5 and Unity 5.1.2 on iOS and I'm getting a black screen with no rear-facing camera showing. Looking at the output (posted below), here are some problems I noticed:
- 2015-08-01 10:47:58.812 arcliff[10697:5076622] VideoBackgroundConfig with screen size of zero received, skipping config step
- 2015-08-01 10:47:58.891 arcliff[10697:5076622] *** -[AVCaptureVideoDataOutput setVideoSettings:] - videoSettings dictionary contains one or more unsupported (ignored) keys: (Width,Height)
- View port sizes of left and right camera are not identical. This is currently not supported by Vuforia!
- I checked the Cardbard left and right cameras and the viewport width and height are identical at (0.5,1.0)
I know it is recommened to revert back to Unity 4.6.7, but this would be very inconvenient as our existing VR projects are already in Unity 5. I did follow the recommendation to enable the Development Build option in the build settings but that didn't help.
Here is the log:

Vuforia 5.0.5 and Unity 5.1.2: Can't get AR Camera to Work
Here is a screenshot of the issue in the Unity editor. The issues I see are:

Hi,
Vuforia 5.0.5 and Unity 5.1.2: Can't get AR Camera to Work
Vuforia 5.0.5 and Unity 5.1.2: Can't get AR Camera to Work
I'm having the same black screen issue too. Even though I'm using Unity 4.6.7. I've also follwed the integration steps. Do you have any ideas?
Vuforia 5.0.5 and Unity 5.1.2: Can't get AR Camera to Work
In iOSVRDevice.cs, in the OnFocus method you should find a line of code like:
launchOnboardingDialog();
remove (or comment out that line), and you should see the app start correctly in Unity 4.6.7, assuming you have followed all the other steps documented here:.
