this is an array[4] of motion compensation functions for 1 horizontal blocksize (16) and the 4 halfpel positions
*pixels_tab[0][ xhalfpel + 2*yhalfpel ]
- Parameters
-
block destination into which the result is averaged (a+b)>>1 pixels source line_size number of bytes in a horizontal line of block h height
