FFmpeg projekti arendajad teatasid uutest assembler-optimiseerimistest, mille abil, kasutades AVX-512 k\u00e4skude kogumit, suudeti kiirendada mitmeid operatsioone, mida rakendatakse video dekodeerimisel. Assembler-koodi j\u00f5udluse t\u00f5us AVX-512 k\u00e4skudega oli 94, 44, 64 ja 4,24 korda v\u00f5rreldes p\u00f5hiversiooniga, mis oli kirjutatud C keeles ilma SIMD-k\u00e4skude kasutamiseta. AVX-2 k\u00e4skudega optimeeritud assembler-koodi j\u00f5udluse t\u00f5us oli vastavalt 67, 27, 55 ja 4,38 korda, samas kui SSSE3 k\u00e4skude puhul 40, 21, 29 ja 2,49 korda. Muudatused on lisatud dav1d raamatukogu, mis pakub alternatiivset dekodeerijat video kodeerimise vormingule AV1. AVX-512 k\u00e4sud on saadaval AMD protsessorites, mis p\u00f5hinevad Zen 4 ja 5 mikroarhitektuuridel, samuti Intel'i protsessorites, mis p\u00f5hinevad mikroarhitektuuridel nagu Skylake-X, Ice Lake, Tiger Lake ja Rocket Lake.
