479 * RECON
480 * Since we have forward dependent frames, we cannot return recon in
481 *encoding order. It must be in poc order, or input pic order. To achieve this
482 *we introduce a delay of 1 to the recon wrt encode. Now since we have that
483 * delay, at any point minimum of pic_cnt in our ref buffer will be the
484 * correct frame. For ex let our GOP be IBBP [1 2 3 4] . The encode order
485 * will be [1 4 2 3] .Now since we have a delay of 1, when we are done with
486 * encoding 4, the min in the list will be 1. After encoding 2, it will be
487 * 2, 3 after 3 and 4 after 4. Hence we can return in sequence. Note
488 * that the 1 delay is critical. Hence if we have post enc skip, we must
489 * skip here too. Note that since post enc skip already frees the recon
490 * buffer we need not do any thing here
491 *
492 * We need to return a recon when ever we consume an input buffer. This
493 * comsumption include a pre or post enc skip. Thus dump recon is set for
494 * all cases except when
495 * 1) We are waiting -> ps_codec->i4_pic_cnt >
496 *ps_codec->s_cfg.u4_num_bframe An exception need to be made for the case when
497 *we have the last buffer since we need to flush out the on remainig recon.
