From c0c808d0cc1b87cf6e0d644ef933fe6b3e7b9247 Mon Sep 17 00:00:00 2001 From: michael Date: Sun, 8 Mar 2009 14:46:10 +0000 Subject: [PATCH] Deprecate the Mersenne Twister. Please use an ALFG, MLFG, LCG or KISS99 generator, MLFG&KISS99 provide higher quality numbers and all should be faster. git-svn-id: file:///var/local/repositories/ffmpeg/trunk@17874 9553f0bf-9b14-0410-a0b8-cfaf0461ba5b --- libavutil/random.h | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/libavutil/random.h b/libavutil/random.h index 4d16eb92d..90378822b 100644 --- a/libavutil/random.h +++ b/libavutil/random.h @@ -38,8 +38,8 @@ typedef struct { #if LIBAVUTIL_VERSION_MAJOR < 50 attribute_deprecated void av_init_random(unsigned int seed, AVRandomState *state); #endif -void av_random_init(AVRandomState *state, unsigned int seed); ///< To be inlined, the struct must be visible.
