Hi Otavio
i made some much accurate tests and I can't notice the previously 
mentioned problem (EGL....Error surface) ,
probably a miss configuration in my cooked image recipe.

But , i found this behaviour :(this are the basic steps)

1)
cooked fsl-image-multimedia-full and add only the cinamaticexperience:
CORE_IMAGE_EXTRA_INSTALL += " \
     packagegroup-fsl-gstreamer-full \
     cinematicexperience \
"

2)
~# Qt5_CinematicExperience -platform eglfs
This application failed to start because it could not find or load the 
Qt platform plugin "eglfs".

Reinstalling the application may fix this problem.
Aborted

3)
root at aepimx53:~# opkg install qtbase-plugins

4)
root at aepimx53:~# Qt5_CinematicExperience -platform eglfs
QFontDatabase: Cannot find font directory /usr/lib/fonts - is Qt 
installed correctly?
Aborted

5)
opkg install qtbase-fonts  -> resolvs the last missing qtbase 
dependencies and QtCinematicExperience runs.

If you want to investigate about the EGL... surface error , I can try to 
reproduce the problem again by removing the egls libraries.

I'll send the kernel and sources patch early to Daiane and 
meta-freescale about the amd-gpu driver

Best Regards
Gianluca
