[Interest] I.MX6 and QT5

[qtnext]

thanks for the info ... I hopes that with I.MX6 it's possible to decode HD
video in hardware and for example remap to an opengl texture or quick2 item
, but I have checked on freescale website and I am not sure if accelerated
decoding is not only for overlay display...
