And reading the second part of your email more carefully, I see that
you already tried running in non-STOC mode :) Left and right shouldn't
be the same image, there's a slight offset that you should be able to
see if you put both images side by side. Try running stereo_image_proc
on those and see if you get proper point cloud.
