I am seeing the same issue with Vuforia 4.2.3 on iOS 8.2 on iPad Mini 2.  The video background is black but image tracking (and AR rendering) does succeed.

I have the same issue on the Android side, as posted in this topic.

I have a similar problem. My project is based on Unity3d 5.1. Integrated Vuforiya SDK 4.2.3 and new version Cardboard SDK. The platform - iOS. Any ideas?

Hi,

I was able to reproduce the problem with the Vuforia examples. It's not Unity related, because I'm using native iOS SDK 4.2.3.

Any feedback? Were you Vuforia guys able to reproduce the issue?

The problem is blocking submission of several apps so I hope we get a fix or at least a workaround very soon.
