Read the YUV420 stream file on test.yuv created by the mxc_v4l2_capture test as run
in test FSL-UT-V4L2-capture-0010. Apply color space conversion and resize, then
display on the framebuffer.
NOTE
The PRP channels require the stride line to be a multiple of 8.
For example, with no rotation, the width needs to be 8 bit
aligned; with 90 degree rotation, the height needs to be 8 bit
aligned. Downsizing cannot exceed 8:1. For example, for a
VGA sensor, the smallest downsize will be 80x60.
6.5.3 IPU Device Unit test
There is a test application named mxc_ipudev_test.c under the <ltib_dir>/rpm/BUILD/
imx-test-"version"/test/mxc_ipudev_test directory.
Before running the ipu device test application, make sure that the /dev/mxc_ipu is
created.
