    Hi!

    I would like to obtain from VUFORIA ARCamera frame a texture2D.
    I can do it on UnityEditor.
    But, if I try it on Android, the method returns always an empty image.
    How can I solve this?
    The chosen pixelFormat is supported by the device.

    Thank you all!

    For Android and IPhone , C# script:-

    Code (CSharp):
    1. if (CameraDevice.Instance.SetFrameFormat(Image.PIXEL_FORMAT.RGB888, true)) {
    2. Debug.Log("Successfully registered pixel format " + mPixelFormat.ToString()); }
    3. else  {
    4. Debug.LogError("\nFailed to register pixel format: " + mPixelFormat.ToString() + "\nThe format may be unsupported by your device." + "\nConsider using a different pixel format.\n");
    5. return;
    6. }
    7.  
    8. Image image = CameraDevice.Instance.GetCameraImage(Image.PIXEL_FORMAT.RGB888);

    Try to do it in the next frame using Coroutine. Vuforia scripts examples works only in theory in clear proejects, not in real situation.. So make slow and safe code

    He is right. I was receiving a null because I was calling CameraDevice.Instance.GetCameraImage in the firs Update frame.

    Thank you mate
