From 1dac8fea056a907a965c60199a13ba49dc8bdc3e Mon Sep 17 00:00:00 2001 From: Aurelien Jacobs Date: Tue, 12 Sep 2006 20:58:17 +0000 Subject: [PATCH] Enables back the mmx/sse optimized version of the vp3 idct. It generates different md5sum than the reference C implementation, but no visual difference, so enabled only when bitexact is not set.
