Subject: Add indep loop for motion_compensated_prediction
X-Git-Tag: v1.8.0~239^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=81f94b893b2bd64eb28a8817bb9684380770e16c;p=libvpx

Add indep loop for motion_compensated_prediction

This is for non_greedy_mv experiment only
This is part of the change of changing mv search order according
feature_score.
