If you specify luma_only as true, the decoder will only allocate memory for the Y buffer, not the Cr/Cb buffers and will avoid any code that might try to modify cb.data or cr.data. This is useful in an embedded context where you're driving a monochrome screen or don't have enough memory to decode color.
