Eglfs and VNC parallel

  • 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?

    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?
