Rendering video on user created wayland surface using gstvideooverlay - arm

Question

I am trying to play a video file over self created wayland surface but rendering is not happening. I took reference from
https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstvideooverlay.html
and
https://git.collabora.com/cgit/user/gkiagia/gst-wayland-gtk-demo.git/tree/main.c
After creation of pipeline (filesrc->parser->decoder->waylandsink); I am setting bus_set_sync_handler as
gst_bus_set_sync_handler (bus, (GstBusSyncHandler) create_window_own,
gstreamerData.pipeline, NULL);
Implementation of create_window_own is below
static GstBusSyncReply create_window_own (GstBus * bus, GstMessage * message, GstPipeline * pipeline)

if (counter == 0)

exit(1);
}

wl_registry_add_listener(registry, &registry_listener, NULL);
wl_display_dispatch(display);
wl_display_roundtrip(display);
if (compositor == NULL) {
fprintf(stderr, "Can't find compositor\n");
exit(1);
} else {
fprintf(stderr, "Found compositor\n");
}
surface = wl_compositor_create_surface(compositor);
if (surface == NULL) {
fprintf(stderr, "Can't create surface\n");
exit(1);
} else {
fprintf(stderr, "Created surface\n");
}
shell_surface = wl_shell_get_shell_surface(shell, surface);
if (shell_surface == NULL) {
fprintf(stderr, "Can't create shell surface\n");
exit(1);
} else {
fprintf(stderr, "Created shell surface\n");
}
wl_shell_surface_set_toplevel(shell_surface);
wl_shell_surface_add_listener(shell_surface,
&shell_surface_listener, NULL);
create_window();
//paint_pixels();
wl_surface_attach(surface, buffer, 0, 0);
//wl_surface_attach(surface, NULL, 0, 0);

pthread_create(&tid, NULL, myThreadFun, (void*)display);
printf("After Thread\n");
counter = 1;

if (display != 0) {

Answer 1

set after create window
wl_shell_surface_set_fullscreen(shell_surface,
WL_SHELL_SURFACE_FULLSCREEN_METHOD_DEFAULT,
0, NULL);
