gstreamer windowsless opengl rendering (wayland)

I have been struggling to get gstreamer opengl running on my remote target
(without monitor so no X server). My target is a NVIDIA TK1 board.
I have no issue of running opengl gstreamer pipeline on my another target
which can connect to a hdmi output.
It seems that wayland/EGL is the right direction to go but I have issue of
creating a wayland display. wl_display_connect() will just failed.
My question is does wayland work without a physical display?
If it does, should I run a wayland server and how?
Any advice about how to get windowless opengl rendering with gstreamer
running in general?
Here is my pipeline and error message:
Insider function gst_gl_display_new() gst_gl_display_wayland_new will just
failed and a egl display will be created. gst_gl_window_new() will fail as
wayland window is only able to connect a wayland display.
