y0

Pointer to upper destination Y component row. y0 must be 8-byte aligned.

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 ABGR multi-component row must be 4*n.

Return Values
