| 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.
