Subject: vp9: Initialize source variance in nonrd-pickmode.
X-Git-Tag: v1.8.0~547^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=51f4f9257d74659392acd735e6a1eb073e858bf9;p=libvpx

vp9: Initialize source variance in nonrd-pickmode.

It is already initialized at superblock level, but since
it is computed per coding block, based on some speed features,
better to initialize it in pick_inter.

No change in behavior, as currently the speed features
that enable use of source_variance in pick_inter are fixed
at the frame-level.
