NVENC not working

Trying to build spice-streaming agent with gst-plugin to get h264 stream. Last known working config was gstreamer-1.16 (ubuntu system, rebuilt via apt-source etc.) After building from last master gstreamer-full-1.0 with following options:

-Ddefault_library=static -Dauto_features=disabled -Dbad=enabled -Dgst-full-libraries=app -Dgstreamer:registry=false -Dgst-plugins-bad:nvcodec=enabled -Dgst-plugins-bad:autoconvert=enabled -Dgst-plugins-base:app=enabled build

(with modified gstreamer init according to static-plugins examples) I can get following debug output:
