EGLsurface to clutter explicitly from the application

[RAHUL KUMAR <rahul blessing gmail com>]

Question: Is there a way to pass my EGLsurface to clutter explicitly from the application?

 

I am trying to profile clutter on an ARM target (also analyse call-flow upto GLES) and was wondering how much impact a rendering surface has on the FPS.

 

With Cairo_Surface:       So far I have tried Cairo with different surfaces like Image, Xlib, EGL and results vary for different surface.

 

Without Cairo_Surface :Now I want to check FPS by directly using the EGL surface created explicitly in my Cluttter Application. I have seen COGL code for "_cogl_winsys_egl_onscreen_init" but was wondering if it is possible to use an EGLsurface created from the application directly.

 

Regards,
