Subject: vp9: 1 pass CBR: avoid nonrd_pick_partition on segment.
X-Git-Tag: v1.7.0~569
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6557baf3363e967c05da910daf3ec41d22594e2d;p=libvpx

vp9: 1 pass CBR: avoid nonrd_pick_partition on segment.

For speed 5, 1 pass CBR: Don't use the nonrd_pick_partition
on the segment, rather use choose_partitioning followed by
nonrd_select_partition (as is done on base segment).

Little/no quality loss on RTC and RTC_derf (< 0.3%),
speedup of at least 5%.
