How to integrate glimagesink into a custom qt player on wayland

[jared Hu]

Is there any one who know how to integrate glimagesink into a custom qt
player on wayland. I got wl_surface from QPA like this, and set this handle
to glimagesink:

QPlatformNativeInterface *native =
QGuiApplication::platformNativeInterface();                                                                                                                                                                                                                                 
struct wl_surface* surface = native->nativeResourceForWindow("surface",
Widget->window()->windowHandle());                                                                      
 
but when pipeline set to play, it will report error:

wl_display at 1: error 1: invalid arguments for
wl_subcompositor at 5.get_subsurface

** (test_wl_surface:8266): CRITICAL **: Failed to flush Wayland connection

Do any one know why?
