...e, but I'm have some problems,
because I work with 16 bit per component and not 8 like theora. I know
that it is off topic, but I'm posting to ask you a little help.
I've got this function that calculates the sad:
si32
sad_4x4 (macroblock_t * mb, ui8 x, ui8 y)
{
ui8 i, j;
si32 corner_x, corner_y, sad;
corner_x = x << 2;
corner_y = y << 2;
sad = 0;
for (i = 0; i < 4; i++)
for (j = 0; j < 4; j++)
sad +=
abs (mb->orig_mb[corner_x + i][corner_y + j] -
mb->pred_mb[corner_x + i][corner_y + j]);
return sad;
}...
