I even read the x264. It seems that the SSD in RDO is computed after the reconstraction. But to the best of my knowledge, It can be gotten directly from the transform domain exactly. A scale for coefficients is needed for the transform in H.264. So after de-quantization, the SSD can be gotten. The IDCT and add to mc signal is bypassed. But I have no time now to write it.
