Compared to LFGs this needs less state. (our LFG has 224 byte state for its 32bit version) this has 32byte state Also the initialization for our LFG is slower. This is also much faster than KISS or PCG. This commit replaces the broken LCG used before. (broken as it had only a period ~200M due to being put in a double) This changes the output from random() which is why libswresample.mak is updated, update was done using the command in libswresample.mak Signed-off-by: Michael Niedermayer --- libavutil/eval.c | 24 +++- libavutil/sfc64.h | 85 ++++++++++++++ tests/fate/libswresample.mak | 208 +++++++++++++++++------------------ tests/ref/fate/eval | 2 +- 4 files changed, 210 insertions(+), 109 deletions(-) create mode 100644 libavutil/sfc64.h diff --git a/libavutil/eval.c b/libavutil/eval.c index dc6b3697bc2..349015d4fa3 100644 --- a/libavutil/eval.c +++ b/libavutil/eval.c @@ -35,6 +35,7 @@ #include "internal.h" #include "log.h" #include "mathematics.h" +#include "sfc64.h" #include "time.h" #include "avstring.h" #include "timer.h" @@ -55,6 +56,7 @@ typedef struct Parser { void *log_ctx; #define VARS 10 double *var; + FFSFC64 *prng_state; } Parser; static const AVClass eval_class = { @@ -173,6 +175,7 @@ struct AVExpr { } a; struct AVExpr *param[3]; double *var; + FFSFC64 *prng_state; }; static double etime(double v) @@ -231,8 +234,14 @@ static double eval_expr(Parser *p, AVExpr *e) #define COMPUTE_NEXT_RANDOM() \ int idx = av_clip(eval_expr(p, e->param[0]), 0, VARS-1); \ - uint64_t r = isnan(p->var[idx]) ? 0 : p->var[idx]; \ - r = r * 1664525 + 1013904223; \ + FFSFC64 *s = p->prng_state + idx; \ + uint64_t r; \ + \ + if (!s->counter) { \ + r = isnan(p->var[idx]) ? 0 : p->var[idx]; \ + ff_sfc64_init(s, r, r, r, 12); \ + } \ + r = ff_sfc64_get(s); \ p->var[idx] = r; \ case e_random: { @@ -329,7 +338,11 @@ static double eval_expr(Parser *p, AVExpr *e) case e_div: return e->value * (d2 ?
