Hi Otavio,

I have been facing issue with EGLFS in QT5, I am also using fido branch for
QT5 and the kernel built is 3.10.17 for imx6q board from freescale.

The video widget example application was not running videos properly
specially videos with high definition. There were lot of warnings saying "A
lot of buffers are dropped". This problem while using EGLFS and linuxfb.
Then i built and installed the QTgstreamer package which has a different
implementation for creating video surfaces. The example player application
in QT-gstreamer works fine for X11 windowing system and Linuxfb, the videos
are played smoothly, but when i try to run the same example application with
EGLFS it crashes and no error message is displayed. I tried enabling debug
messages but no luck.

Best Regards
Sriram
