[meta-freescale] X11 is not working on IMX.6

[Fikret Alim]

Dear Andre,

I checked the software, it look for Up.mp4 under /home/gesture directory. I
have copied it and now the it is running, but the problem is I can only see
the video is playing. Neither I see webcam output, nor gesture recognition
works. I use my webcam normally at /dev/video0 and I can use it with my
OpenCv applications directly.

Thanks,
Fikret
