Subject: vp9-rtc: Avoid TM intra on big blocks for screen
X-Git-Tag: v1.8.1~194^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0ebc986a33942d877cf7b227b3c8c4aedf3b29a2;p=platform%2Fupstream%2Flibvpx.git

vp9-rtc: Avoid TM intra on big blocks for screen

For screen content real-time mode: don't check TM
intra for bsize >= BLOCK_32X32.

Small speedup and avoid some artifacts seen
in scrolling screen content.
