Play icon not visible on image target in Vuforia Video Playback in Xcode

March 23, 2017 - 10:33pm #1

I'm experimenting vuforia video playback in xcode. I successfully run the sample application. Now Im trying to change the database. I have loaded the database as mentioned below.

// load the data associated to the trackers

- (bool) doLoadTrackersData {

return [self loadAndActivateImageTrackerDataSet:@"vuforia.xml"];;

}

There are two image targets in vuforia.xml database (vuforia.dat) named twitterlogo and appzone. I can detect the appzone image target but I can't detect appzone image target. As well as play icon is not visible on appzone image target. If I click on the appzone image target, relevant video is played. Now I need to know why twitterlogo image target is not detected and play icon is not visible on the image when target is detectedCan anyone help me to fix this issue.

 

// VideoPlayerHelper to use for current target

    int playerIndex; 

    if (strcmp(imageTarget.getName(), "twitterlogo") == 0)

    {

        playerIndex = 0;

    }

    else if (strcmp(imageTarget.getName(), "appzone") == 0)

    {

        playerIndex = 1;

    }

Hello,

 

I am having the same issue, I downloaded the sample and its working properly.

When I created new database and run the project, video icon is not displaying,

but when clicked on captured image video plays and can listen audio, but video didn't display.

I am using vuforia-sdk-ios-7-1-34 with iPhone 6 with iOS 11 version.Created using xcode 9.

If anyone have solution, plz let me know.

Hi

 

Many many thanks for your response. I have tested vuforia's chips and stone images. It works fine. When I change the image targets only, I'm facing this issue. As per your instructions, I have also used the large image targets. Still same issue continues. I already done this in android using android studio. In android, I've customized the sample code as per my requirements. It works fine. I'm getting issue in iOS only.

 

Regards,

Muhilan

Hello,

For the target detection issue, one common error is that the printed target was not printed in the exact aspect ratio of the original. Any image stretching can keep Vuforia from detecting the target.

For the icon not appearing issue, perhaps the far clipping plane has been set too close? Try setting this to a very large value and try again.

My last recommendation is to first use Vuforia's chips and stones targets for your prototyping exercises (if you have not already done so). This could help to eliminate the new targets as an unknown.

Thanks.
