IMX8 GStreamer videocrop

[Kettle]

Hi,

I'm trying to crop camera video using the following pipeline in qt5 qml mediaplayer: 

gst-pipeline: v4l2src device=/dev/video0 ! video/x-raw,width=640,height=480 ! videocrop left=200 right=100 bottom=0 top=0 ! videoconvert ! qtvideosink

This pipeline works well on pc, but when I launch the application in IMX8 it breaks the video.

So the question is how to use videocrop with IMX8? Any help would be much appreciated.
