/* The checks use as test data an 8x8 Y444 image, with 25 Hz framerate. In the
 * sink caps configuration, the stride is 8 bytes, and the frames are tightly
 * packed together. In the properties configuration, the stride is 10 bytes, the
 * planes aren't tightly packed (there are 20 bytes between the planes), and the
 * frames overall have padding between them (the overall frame size is
 * stride (10) * height (8) * num-planes (3) + bytes-between-planes (20) * 2
 * = 280 bytes, and the frame stride is 500 bytes, so there are 220 bytes of
 * extra padding between frames).
 *
 * In the test 8x8 frame, the pixels are all set to #000000, except for two
 * pixels: (xofs+1 yofs+0) is set to #8899AA, (xofs+0 yofs+1) is set to #112233.
 * The first frame uses the offsets xofs=0 yofs=0. The second frame uses
 * xofs=1 yofs=0 etc. For each configuration, there is a separate set of frames,
 * each stored in the GstAdapter in the Context struct.
 *
 * During the tests, as part of the checks, the pixels are verified to have the
 * right values. The pattern of the pixels was chosen to easily detect stride
 * errors, incorrect plane offsets etc.
