[x264-devel] [PATCH] SSE2 motion compensation [from before] + MMX/SSE2/SSSE3 frame_lowres_init

[Hannes Domani]

Hello

when looking at the patch i was wondering if the
following part is what you really intended (since x++
is called twice):
> -    if( qpel_idx & 5 ) /* qpel interpolation needed
*/
> +    int x;
> +    width = width >> 2;
> +    for( x = 0; width - x >= 2; x++ )
>      {
> -        uint8_t *src2 = src[hpel_ref1[qpel_idx]] +
offset + ((mvx&3) == 3);
> -        x264_pixel_avg_wtab_mmxext[i_width>>2](
> -                dst, *i_dst_stride, src1,
i_src_stride,
> -                src2, i_height );
> -        return dst;
> +        frame_init_lowres_core_sse2_w32(src_stride,
dest_stride, height, width, src0, dst0, dsth, dstv,
dstc );
> +        src0 += 32;
> +        dst0 += 16;
> +        dsth += 16;
> +        dstv += 16;
> +        dstc += 16;
> +        x++;
>      }
