gstreamer-1.0 plugin for videosink without X

[Marco Trapanese]

Hello,
I'm customizing a Raspbian Jessie Lite image for Raspberry Pi 3 (without 
X server) and I compiled gstreamer 1.8.2 from sources.
The goal is to a have a videosink for OpenGL ES2.0 (which should not 
require X) and to use gstreamer as a backend for QtMultimedia (Qt5.7.0).

On stackoverflow I received an hint to use glimagesink as videosink but 
it still looks for X server.
Please, would you help me to understand what plugin I need?

Thanks!
