Subject: [FFmpeg-devel] [PATCH] avutil/eval: Use better PRNG
Date: Wed, 3 Jan 2024 23:24:33 +0100
Message-ID: <20240103222433.18444-1-michael@niedermayer.cc> (raw)
This is the 64bit version of George Marsaglias KISS PRNG
Compared to the LCGs these produce much better quality numbers.
Compared to LFGs this needs less state. (our LFG has 224 byte
state for its 32bit version) this has 32byte state for the 64bit version
Also the initialization for our LFG is slower.
OTOH the LFG is probably faster.
