That's great. You're welcome.

Hello,

I uninstalled the app, then installed it again.

Everything's fine. It is not streched anymore. 

Thanks for the feedback; it is really really appreciated.

Thanks again

Hi, the device profile for your device has been updated;

could you try again ?

please, when doing the test, make sure to first clear the cache (or even completely uninstall the app) and reinstall theapp again (this is of key importance), and make sure that you have internet connection enabled.

Hello,

Thanks for the input. I really hope to have a fix of this issue.

Thanks again.

I will udpate you as soon as we have a fix for this.

Hello,

Thank you for the input, it is appreciated.

Although this workaround does not work. 

In the startCamera method:

Hi, meanwhile, as a workaround, you could retrieve the actual width and height used by your camera via this code (and use these values in the configureVideoBackground() instead of the videoMode.mWidth and videoMode.mHeight which are incorrect):

QCAR::Frame frame = state.getFrame();
const QCAR::Image *image = frame.getImage( 0 );
int videoWidth = image->getWidth(); 
int videoHeight = image->getHeight();

Hi, that's perfect. I will be in touch with you as soon as I get an update.

Hello,

Thanks for your input, it is really appreciated.

Here are my device information. It is a Galaxy S3.

Model number : SGH-T999V

Android Version : 4.1.1

Baseband version : T999VVLDLL1

Build Number : JR003L.T999VVDLL1

I hope these information will help.

Thanks again.

Hi, I compared the numbers (width and height) that you get with the ones I get (for the same MODE_OPTIMIZE_QUALITY) and I realized they are actually slightly different;

this means there is an issue with the Device Profile for your device; even if it is a Galaxy S3 like the one I tested on, the specific model is certainly different (i.e. not all S3 have the same hardware and software, there can be quite some differences); in our database we are aware of at least 5 or 6 different types of Galaxy S3.

So, to fix the issue, I would need from you the exact model number of your device and the Android version as well; you can get this information from the Settings -> About Device

Hello,

Thanks for your input , it is appreciated.

I have tested several times the FrameMarker sample app (v2.0.6) without any modification on my Galaxy S3 and it look stretched; it is very noticeable when you turn the phone in Portrait.

The markers look rectangular not square.  So there is certainly an issue somewhere. I don't think there are different types of Galaxy S3, so you should also have the same result on your Galaxy S3.

Anyway, I hope there is a fix for this. 

Thanks

Hi, videoMode.mWidth and videoMode.mHeight represent the resolution of the Camera image (i.e. the video frames captured by the camera); this has no relationship with your device screen resolution, which can be much higher of course (e.g. 1280 x 720).

The purpose of the configureVideoBackground() function is exactly to make the necessary calculations so to compensate for those differences when the video background texture is displayed by QCAR.

Hello,

Thank you for you input. It is appreciated.

This is exactly what I am doing. I use MODE_OPTIMIZE_QUALITY in both places.

I setup my application to Landscape and the markers are not squares, they look rectangular. You can really see that when you turn the phone in Portrait.

Could you please tell me why ( videoMode.mWidth, videoMode.mHeight) returns (800,480) and not (1280,720) ? 1280x720 is the actual screen size.

Is it possible to have  ( videoMode.mWidth, videoMode.mHeight) returns (1280,720) or to set these values ?

Thanks again.

Hi, all the samples contain a function called configureVideoBackground() (see native code in FrameMarkers.cpp for instance);

in such function, the videobackground image gets configured by taking into account the actual resolution of the camera (see variables videoMode.mWidth and videoMode.mHeight) and the resolution of the screen as well (for instance 1280 x 720 in your case, as you mention);

a set of calculations are done so to apply a proper size to the background (i.e. in practice the videobackground is configured in such a way so to eliminate any stretching artifcats due to the different resolutions of the screen versus the camera video feed);

if you are using MODE_OPTIMIZE_QUALITY however (instead of the DEFAULT), you should make sure that you use that mode both when you select the camera mode (i.e. in the startCamera() function) and when you retrieve the videoMode in the configureVideoBackground() function, i.e.:

if (!QCAR::CameraDevice::getInstance().selectVideoMode(
                                QCAR::CameraDevice::MODE_OPTIMIZE_QUALITY))
        return;

and here:

void
configureVideoBackground()
{
    // Get the default video mode:
    QCAR::CameraDevice& cameraDevice = QCAR::CameraDevice::getInstance();
    QCAR::VideoMode videoMode = cameraDevice.
                     getVideoMode(QCAR::CameraDevice::MODE_OPTIMIZE_QUALITY);

If you use different parameters in those two places, you might end up with inconsistencies and thus stretched images.

I hope this helps.

(Note: I just tested the samples Apps on my Galaxy S3 and did not observe the stretching)
