Webcam texture rotation

[gonza moiguer]

Hi, i'm trying to use a webcam as a vertical image, but when physically rotated, the face is no longer detected. I assume this is because the landmarks are no longer found in the place they are expected to be.
What steps should I follow to internally rotate the webcam image before the face tracker tracks the webcam texture?
thanks in advance

Silly me. Will leave this here in case someone else runs into this.
After
webCamTextureToMatHelper.initialize();
add
webCamTextureToMatHelper.rotate90Degree = true;
