Hi,

I took the video player example from the core example scenes and used it for my AR app. Since a few days, I got the error (see image : https://developer.vuforia.com/sites/default/files/error_30.png)

Since then, the videos wont pause when tracking is lost.

Any idea why this is or how to fix this?

Here my eventHandler code:

public class VideoTrackableEventHandler : DefaultTrackableEventHandler

{

    #region PROTECTED_METHODS

    protected override void OnTrackingLost()

    {

        mTrackableBehaviour.GetComponentInChildren<VideoController>().Pause();

        base.OnTrackingLost();

    }

    #endregion // PROTECTED_METHODS

}
