[meta-freescale] imxvpudec crash with 3.14.28 and gstreamer1.0

[Carlos Rafael Giani]

Can you try out the example program I attached? Just run it like this:

GST_DEBUG=2,*imx*:5 ./loop-videos -i 5000 -v "imxipuvideotransform ! 
imxeglvivsink" /home/root/B01_Baseline1.0_1280_720.MP4

This will run the mp4 video for 5 seconds and then start again. Note 
that you have to build it with the -std=c++11 compiler flag.
