<div>Hi:</div>
<div> I recently studied the x.264 encoder, I'm puzzelled by the function "x264_mb_cache_fenc_satd()".</div>
<div> It seems this funciton take source Y plane image data as input which pointed by h->mb.pic.p_fenc[0] and output are: <font color="#ff0000">h->mb.pic.fenc_satd[y][x], h->mb.pic.fenc_sa8d[y][x],</font> <font color="#ff0000">h->mb.pic.fenc_satd_sum</font> and <font color="#ff0000">h->mb.pic.fenc_sa8d_sum</font></div>
<div> However, I searched the whole project for these four vairant, It seems no function refered the above variants, then, why we use this funciton? what the use of it?</div>
<div> </div>
<div> I hope anyone can help me on this issue</div>

<div>Best Wishes!</div>
