Does uridecodebin output NVMM

This worked in Jetson TX2 with DS 1.5

uridecodebin ! nvegltransform ! nveglglessink -e

In the Nano with DS 4.0 I need to insert nvvidconv

uridecodebin ! nvvidconv !nvegltransform ! nveglglessink -e

Is this expected or there is something wrong with my installation?

Many thanks for any help.

You may configure GST_DEBUG to know which decoder is selected by uridecodebin.
