No features in Ubuntu 18.04 (Headless mode)
When I logged in to the Ubuntu 18.04 server on the console, and when I enter "gst-inspect-1.0 vaapi" command, I get 14 features with vaapih264enc available. When I logged out of the console, and SSH into the server, and type the same command, I get 0 features and vaapih264enc becomes no longer available.
