jetson camera image is rotated on target device

I am attempting to run this example:

Everything works great but for some reason the camera window and image are rotated -90 degrees. Is there a way to send a message to rotate the image? when I run this command on the target:

ffplay /dev/video0

it looks fine.

MATLAB is column major. If you want the image to be row-major, you need to transpose the image. In the example, there is a transpose for displaying the image:

% Display image.
image(dispObj,edgeImg');
