Subject: Revert "vp9: Avoid encoder loopfilter for non-reference frames."
X-Git-Tag: v1.7.0~562
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e9b7f98c56b3b9c99a60eb41b83bf8346b3ad25f;p=platform%2Fupstream%2Flibvpx.git

Revert "vp9: Avoid encoder loopfilter for non-reference frames."

This reverts commit 863f860bfcf3bdc26eeecb299aa481d0f63d11ac.

This causes encoder / decoder mismatches in various
VP9/DatarateTestVP9Large.BasicRateTargeting3TemporalLayers tests

BUG=webm:1408
