Subject: Nonrd_pickmode: avoid computing UV cost when early_term is set.
X-Git-Tag: v1.7.0~81
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6fbc354c97ca45754a76674dba5f6b43c2b0c15a;p=libvpx

Nonrd_pickmode: avoid computing UV cost when early_term is set.

For nonrd_pickmode: if early_term is set there should be
no need to include UV in rdcost (when color_sensitivity is set).

Neutral change on RTC and RTC_derf metrics, for speed >= 5.
No change for ytlive metrics.

Very small speed gain (~0.5%) on some clips with strong color content.
