      Hey everybody,

      I have a qt 5.15 application which is running on a raspberry. It is showing the qml-gui via eglfs.

      So far, so good.
      Now I want to use vnc for remote assistance.
      As I‘m not using X11 I don't know how to use vnc.
      I can start my application with -platform vnc, but then I only see the gui via VNC and my display keeps blank.

      Any idea?

        Hi,

        AFAIK, there's no "multiple qpa" output with Qt 5. So you can't do it that way.

          Do you know if there is an option in any standard vnc-server to access the egl-content?

            I have searched the web now for many hours, but I could not find a solution to share my application via vnc.

            So, new idea:
            I implement libVncServer, grab my qmlView and implement vnc myself.
            The question is: Has anybody done this before?
            How can I access the qml-framebuffer?
