<p>This structure holds per-macroblock information. The buffer must be allocated with as many elements (macroblocks) as necessary to fit the slice to be encoded. Besides, the per-macroblock records must be written in a strict raster order and with no gap. i.e. every macroblock, regardless of its type, shall have an entry. </p>
