Subject: Set the skip flag to 1 for skippable blocks
X-Git-Tag: v1.4.0~773^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=46aed7b8d0b5f6f33d047c47a229f0f93033e39e;p=platform%2Fupstream%2Flibvpx.git

Set the skip flag to 1 for skippable blocks

If the partition block is skippable, which means no coefficients
for Y, U, and V planes, its skip flag is set to 1. No quality
change (verified by borg tests), and no noticeable speed change.
