  <p>At  some point I will need to mount my camera (waveshare ; IMX219-77IR) on  top of the drone and I would like to use  Windows or Linux outside of nomachine (because the nano will be in  headless mode),to display what the camera sees  when the drone is flying.

  <p>it didn't work,but I found the reason and I fixed it. All my steps were correct, except that I was using the latest version of the example, which uses the latest API. Since most  Jetson boards come with Gstreamer 1.16 pre-installed, I used that same version of the example:</p>
