y1 Pointer to lower destination Y component row. y1 must be 8-byte aligned.
cb Pointer to destination Cb component row. cb must be 8-byte aligned.
cr Pointer to destination Cr component row. cr must be 8-byte aligned.
abgr0 Pointer to upper source ABGR multi-component row. abgr0 must be 8-byte aligned.
abgr1 Pointer to lower source ABGR multi-component row. abgr1 must be 8-byte aligned.
n Length of Y component row. n must be even. The length of Cb and Cr component rows must be n/2. The length of the RGB multi-
component row must be 3*n.
