Zero-copy EGLImage texture upload?

Thank you for your work but the communication is difficult.

My use case is:

an GL window is created by the app, the pipeline app sink get the frame and display the frame inside the existing window/GL context.


 processing -> pipeline -> appsink
                             !
                             !
                             !
gui_app  <-------------- create texture                               
(create window,        (without copy of frame data)
create GL context)                                                 !
swap buffers

This impossible that it is not working this a the basic of graphic engine (ask for support)
