From a5704659e3e41b7698812b89f67d9a7467a74d20 Mon Sep 17 00:00:00 2001 From: Nicolas George Date: Tue, 28 Aug 2012 18:15:49 +0200 Subject: [PATCH] lavfi/af_atempo: use av_malloc for rDFT buffers. Memory obtained from av_realloc is not aligned enough for AVX. The other similar allocations are changed too because they use the same macro. The buffers were cleared afterwards anyway.
