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@aepimx53:~# opkg install qtbase-plugins

4)
root@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
