x264

[Henry Hu]

Hi,
I'm using FreeBSD 7.1-STABLE
Since I'm using 20090101, something is different.
In analyse.c:
            p_cost_mv[a->i_qp][i]  = a->i_lambda * bs_size_se( i );
In bs.h:
static inline int bs_size_se( int val )
{
    return bs_size_ue_big( val <= 0 ? -val*2 : val*2-1 );
}

In bs.h:
static inline int bs_size_ue_big( unsigned int val )
{
    if( val < 255 )
        return x264_ue_size_tab[val+1];
    else
        return x264_ue_size_tab[(val+1)>>8] + 16;
}

So it got the value from a table, not log2f...
