From 7943355485cf889c14f9c4151f917ae2be01ee73 Mon Sep 17 00:00:00 2001 From: Benjamin Larsson Date: Sun, 2 Jul 2006 02:05:35 +0000 Subject: [PATCH] ff_fft_init now double checks that the system has mm3dnow.h before checking if the cpu can do 3dnow at all. This bug caused amd cpu's without sse to not have a working fft function. Ie no wma, cook or vorbis decoder.
