Decoding failed for Full HD video

Hi,

We are using libimxvpuapi example code(decode-example.c) to test the h.264 decoding with below command on imx nitrogen6x board with linux operating system.

./decode-example -i ../test.h264 -o test.yuv

(test.h264 is the Big Buck Bunny video)

Decoding of h.264 for 320x240 resolution is working , but not working for 1920x1080 resolution, we are getting error as below. Can anyone please help to solve this?

imx vpu can support 1080p decoding, could you test mxc_vpu_test in the unit test or gstreamer? I couldn't reproduce this on my board, but I tested by unit test and gstreamer, decoding is ok.
