Does QCAR works on iOS 5?

Hi - I've responded to your message via private and e-mail messages - can you confirm which of those you've received - I'm having some problems with that feature on the forum.

The deprecation warning is harmless - Apple normally post these warnings if they are considering removing the API in the next major version (presumably 6.0?).

Mosr, I sent you a private message under the username

, forgot to switch usernames, let me know if you need me to resend, also I noticed I'm getting this warning alot:
WARNING: -[ setMinFrameDuration:] is deprecated. Please use AVCaptureConnection's -setVideoMinFrameDuration:

Is this a big deal?

So as an early prediction, dependent on the results of the others, it suggests that there's a change in OpenGL behaviour in iOS5.

(One common source of flickering in OpenGL is apparent co-planar surfaces - where two surfaces are drawn closer together than the resolution of the depth buffer. The renderer get's confused as to which should be drawn on top.)

marchinram, please contact me privately if you'd like us to see if we can isolate this - it would help us be reassured it's not QCAR whilst at the same time maybe we can help you through the problem.

I tried the ImageTargets from qcar 1.0 and it is not flickering in iOS 5, not sure why this is happening, when I ran my app before on iOS 4 there was no problem. My app just displays textured quads and cycles through them like a flipbook animation, anyone have any idea why this would be happening?

1) iPhone 4
2) Native app
3) No, but will do that shortly
4) Xcode 4.2
5) It happens whether I run from Xcode or not

Hi zakharm, marchinram and sdelaroq,

We're keen to learn more about this problem you have observed.

We've tested with iOS5 on an iPhone 4 and 4S, with the native sample apps, and with 3rd party released apps (both native and Unity based) and haven't seen what you are reporting.

Can you help us by providing the following:

1) What is your specific device?
2) Is your app native or built using Unity?
3) Have you tested with the sample apps, native or Unity?
4) What Xcode version are you using?
5) Does the problem happen when running from Xcode and when running the app stand-alone on the device?

Which device are you using, and are you using the native SDK or Unity?

Can you describe the flickering? Do you mean the whole screen flashes, or the augmentaion comes & goes, or something else? I have just run ImageTargets (native) on an iPhone 4S with iOS 5 and it looks OK.

I tried it and it flickers, I verified the same app works fine on a phone with 4.3.5
