Tried to recompile; this time moved the include/*.h files into /usr/local/include/, make cleanup, make and removed the file ~/.cache/gstreamer-1.0/registry.aarch64.bin so I can run again get-inspect and reload the elements. However the problem pop-up again…

Hi,
We will check it. For more information, is there any function failing to run in your usecase? Or it shows the warning but functions are good?

I don’t know, the plugin failed to load.

The compilation was OK.
