From: "Kasireddy, Vivek" <vivek.kasire...@intel.com>
The memory layout of AYUV buffers (V4L2_PIX_FMT_YUV32) should be similar
to V4L2_PIX_FMT_ABGR32 instead of V4L2_PIX_FMT_ARGB32.
While displaying the packed AYUV buffers generated by the Vivid driver
using v4l2-tpg on Weston, it was observed that these AYUV images were not
getting displayed correctly. Changing the memory layout makes them display
as expected.
