From b9eaf6e05c2ca16d94869e0263236dbdac752400 Mon Sep 17 00:00:00 2001 From: Sean McGovern Date: Thu, 28 Nov 2024 14:52:16 -0500 Subject: [PATCH] swscale/ppc: disable YUV2RGB AltiVec acceleration The FATE test 'checkasm-sw_yuv2rgb' currently fails on this platform, in both little- and big-endian configurations with AltiVec enabled. Disable it for the time being.
