From: James Zern Date: Sun, 31 Aug 2014 20:16:37 +0000 (-0700) Subject: move LFWorkerData allocation to VP9LfSync X-Git-Tag: v1.4.0~564^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e9b8810b4d5c1db78ef07b6061b05d2d62d55eb6;p=platform%2Fupstream%2Flibvpx.git move LFWorkerData allocation to VP9LfSync this removes an assumption that worker->data1 would be pointing to a TileWorkerData allocation. additionally, within the multi-threaded loopfilter pass VP9LfSync as a parameter to the worker hook, removing the need for a shadow pointer in LFWorkerData.
