Nvvidconv flip-method NOT working

Test script below

gst-launch-1.0 nvarguscamerasrc wbmode=1 tnr-mode=2 ee-mode=2 ! ‘video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)NV12, framerate=(fraction)30/1’ ! ‘nvvidconv flip-method=2’ ! fakesink

This work on L4T 32.1 but NOT work on L4T 32.3.1

nvbuf_utils: Could not get EGL display connection
WARNING: erroneous pipeline: syntax error

The problem is flip-method

Any idea ?

You would remove the quotes around nvvidconv:

gst-launch-1.0 nvarguscamerasrc wbmode=1 tnr-mode=2 ee-mode=2 ! ‘video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)NV12, framerate=(fraction)30/1’ ! nvvidconv flip-method=2 ! fakesink

Oh, such a stupid problem, thank you
