cf5083d4cd
Major parts have been implemented as follows: (1) Added BRF_UPDATE, LASTNRF_UPDATE, and NRF_UPDATE in firstpass.c; (2) Added the handling for the scenario of "cpi->common.show_existing_frame == 1" at the encoder; (3) Added a new reference frame of BWDREF_FRAME; (4) Have bwd-ref work with upsampled references. Note that when the experiment of "ext_refs" turned on, this experiment will be turned off automatically currently. RD performance in Overall PSNR has been improved, compared against the VP10 baseline: lowres: Avg -3.312; BDRate -3.154 derflr: Avg -1.927; BDRate -1.176 midres: Avg -2.149; BDRate -2.001 hdres : Avg -0.567; BDRate -0.588 Change-Id: I4c06ff51cc20194bffbd4d2346e57ba3dcf6b62c
