Subject: Always partition check after keyframe (rt speed 5)
X-Git-Tag: v1.4.0~1505^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b9c24dfa23f945a6e1dbf9c0d31abe31e2991627;p=platform%2Fupstream%2Flibvpx.git

Always partition check after keyframe (rt speed 5)

Prevents too small partitions from being copied to the next frame.
