Convert 422 interleaved data to 422 MCU


FwStatus   fwiJoin422LS_MCU_16s8u_P3C2R ( const Fw16s * pSrcMCU[3]Fw8u * pDstint dstStep );


dstStep   Destination buffer step size (width of the buffer in bytes).
pDst   Pointer to a location in a destination buffer.
pSrcMCU[3]   Array of pointers to source MCU image blocks.


This function steps through two blocks of interleaved 4:2:2 chrominance sub-sampled pixel data in a source buffer, combines the two channels into a 4:2:2 chrominance sub-sampled MCU, level-shifts the source data to signed values, and writes the output data to a destination buffer.
