I wanted to build and use the latest version of gstreamer, so I uninstalled the existing gstreamer (version 1.14) with the following command.
sudo apt-get remove --purge gstreamer1.0*
After that, I was able to install the latest gstreamer (version 1.23), but I noticed that elements such as nvv4l2decoder were not generated when I built the official gstreamer.
How can I install a gstreamer that can use nvv4l2decoder again?
I have performed the following steps but the required element was not restored.
