Use IMX6 VPU to decode picture problems

[deanji]

HI all:

I use the vpu of imx6 convert jpg picture into yuv picture, the conversion of the image size 4177920

Feel the image size is not right, and turn out the image of the top has a green stripes,

1920X1080=2073600
2073600X2=4147200
4177920-4147200=30720(I think the image size of converted is 1920X1080X2)

ps: my cmd like ./mxc_vpu_test.out -D "-i a.jpg -o b.yuv -f 7" my bsp version is 3.0.35

I would like to ask if  the vpu of imx6 support  this conversion, if does  what is wrong?

thanks!

when i open with  resolution 1920*1088,The green bar disappears。

my next qustions is why not 1920*1080(Original resolution is 1920*1080)

Because of the 16-pixel alignment in VPU.
