Commit 643238a3 authored by Yaowu Xu's avatar Yaowu Xu

changed find_near_mvs search to include a mb from last frame

This is an experiment to include a mv contribution from last frame to
nearest and near mv definition. Initial test showed some small though
consistent gain.

latest patch slightly better result ~.13%-~.18%.

TODO: the entropy used to encode the mode choice, i.e. the mv counts
based conditional distribution of modes should be re-collected to
reflect this change, it is expected that there is some further gain
from that.
