Subject: vp9 non-rd pickmode. Some adjustments for vbr mode.
X-Git-Tag: v1.6.0~303
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=caa8de547f5860bfbb83626811d631dbf6d2b5d1;p=libvpx

vp9 non-rd pickmode. Some adjustments for vbr mode.

Some adjustments to inter-mode selection for vbr mode.
Condition some of the bias to low/zero motion on cbr mode, and
don't use int_pro_motion_estimation for golden ref
(treat it same as last ref).

Change only affect 1 pass vbr mode, speed >=5 (non-rd pickmode).

Encoding time increase within ~5%.
Avg PSNR/SSIM on RTC set increase by ~2%, all clips up,
ranging from 0.5 to 4%.
