Enumerator
MAX_STRIDE
BUF_SIZE	BUF_SIZE is bigger than necessary in order to test strides > block width.
INPUT_BUF_SIZE	The qpel interpolation code accesses two lines above and three lines below the actual src block; it also accesses two pixels to the left and three to the right. The input is not subject to alignment requirements; making the input buffer bigger (by MAX_BLOCK_SIZE - 1) allows us to use a random misalignment.
