I have solved this problem with running gst-launch utility -

gst-launch-1.0 xlnxvideosrc src-type="usbcam" ! "video/x-raw, width=640, height=480, format=UYVY" ! sdxopticalflow filter-mode=1 ! queue ! xlnxvideosink sink-type="dp" plane-id=34 sync=false fullscreen-overlay=true

Note: The e-con USB camera only supports UYVY.
