Sorry but about eglfs+raspberry

[nimadibaj]

Hi,
I have a simple code, with gstreamer.
Just videotestsrc+glimagesink
When I run it :
$: ./sample -platform eglfs
Nothing happens, just shows mouse pointer!
If I run it with vnc instead of eglfs, it works!

OS : Raspberry pi lite, no desktop, egl mem 256MB

Qt config :
EGLFS : YES
Raspberry pi EGLFS : NO

Please guide me
