FwStatus   fwiSampleDown411LS_MCU_8u16s_C3P3R ( const Fw8u * pSrcint srcStepFw16s * pDstMCU[3] );


pDstMCU[3]   Array of pointers to destination MCU image blocks.
pSrc   Pointer to a location in a source buffer.
srcStep   Source buffer step size (width of the buffer in bytes).


These functions step through a block of pixel data in a source buffer, perform chrominance downsampling, level-shift the source data to 16-bit signed values, create a minimum coded unit, and write the output data to a destination buffer.

There are functions for 4:4:4, 4:2:2, and 4:1:1 MCUs.
