Thanks for the reply Matt. Unfortunately I cannot enable GTK+ 3 version in
Buildroot. It requires OPENGL/EGL based on mesa3d. But on raspberry pi we
use native rpi-userland instead of MESA3D. There is separate thread on this
topic.

Ok, Currently glimagesink displays the video in the center of the screen
which is not stretched/scaled ( Not full screen) .. If i dont use GTK
widget, and if i want to render video in full-screen using glimagesink , how
should I proceed.  Can i use gl scaling elements ?

Thanks & Regards
Munez
