Field Documentation

op_pixels_func HpelDSPContext::avg_no_rnd_pixels_tab[4]

Halfpel motion compensation with no rounding (a+b)>>1.

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
