java.lang.IllegalArgumentException с Google Glass

Question

Я работал над стеклом Google с OpenCV и пишу это в методе onCameraFrame:

@Override
public Mat onCameraFrame(CameraBridgeViewBase.CvCameraViewFrame inputFrame) {
    mRGBA = inputFrame.rgba();
    Imgproc.rectangle(mRGBA, new Point(20, 20), new Point(80, 80), new Scalar(0, 0, 255), 100);
    mRGBAT = mRGBA.t();

    Core.flip(mRGBA.t(), mRGBAT, 1);

    Imgproc.resize(mRGBAT, mRGBAT, mRGBA.size());

    Imgproc.rectangle(mRGBAT, new Point(20.0, 20.0), new Point(80.0, 80.0), new Scalar(0.0, 0.0, 255.0), 100);

    System.out.println("here");

    return mRGBAT;

}

и я получил эту ошибку

E/SurfaceHolder: Exception locking surface

Как это исправить.

Спасибо.
