Getting stretched image on phone device Vuforia AR Camera

By rohangarg1998 on Tue, 12/04/2018 - 15:43

Hey i am getting correct image output in unity player , but if i install this in my android phone ( Samsung J7 pro) , i am getting a streached output image . Any advice what should i do?

Hello,

This could be an issue with the camera capture resolution selected by Vuforia performance sets. Try setting to MODE_SPEED or MODE_QUALITY to see if that selects a different resolution that eliminates the stretching effect.

Hello,

Understood, but not necessarily unexpected. The mode-mapping is dynamic and can vary from device-to-device, although I'm a bit surprised that you're not seeing any differences as the system should support more than one.

I suggest you try a different device.

Thanks,

Hi

We are receiving bug reports on a simular device (Galaxy j5) where the camera seems warped and the marker tracking is very bad.

As far as i know, the bug appeared after updating the device to Android 8.1

Hello,

Thanks for the report. We have not yet received similar reports and will investigate further.

Hello @bfisker,

Is your app set to handle auto-rotation, or locked to landscape or portrait?

Normally, Vuforia doesn't do anything when the screen is getting rotated - we only do something *after* the screen has been rotated.

@medabit it has been almost a month. Are there any updates on this?

Hello @bfisker,

We were able to replicate the issue after upgrading a Samsung Galaxy J5 Pro from Android 7 to Android 8. Images captured using Camera 2 on Android 7 look fine - images captured using Camera 2 after upgrade to Android 8 show stretching.

Hello,

After further investigation, and similar to the J5 Pro, there seems to be an issue with the Samsung J7 Pro delivering stretched frames when using Camera2 APIs after upgrade to Android 9.0.

Thanks,
