nvcodec elements missing

I built libgstnvcodec on the 1.22.6 branch and only see cudadownload and
cudaupload elements listed. In particular I'm looking to use the nvh264enc
element. I've installed the latest nvidia drivers plus cuda on my system. I
can't seem to find any docs that provide guidance on what I could be
missing. Any help would be greatly appreciated.

meson setup -Dauto_features=disabled -Dgstreamer:tools=enabled
-Dbad=enabled -Dgst-plugins-bad:nvcodec=enabled builddir
meson compile -C builddir
