R32.3.1 tx2-4g nvvidconv problem

Setting left=1682 right=1692 top=900 bottom=900 makes a frame with zero rows and 10 columns. This cannot be displayed.

You may also set a framerate. Using a RPi v2 camera that can only do 3264x2464@21fps, this works:

gst-launch-1.0 nvarguscamerasrc ! 'video/x-raw(memory:NVMM),width=3264,height=2464, framerate=21/1' ! nvvidconv left=1682 right=1692 top=900 bottom=910 ! 'video/x-raw(memory:NVMM),width=10, height=10' ! nvegltransform ! nveglglessink window-width=480 window-height=380
