FFmpegi projekti arendajad teatasid, et on rakendanud uusi assembleri optimeerimisi, kasutades AVX-512 instruktsioonide kogumit, millega on \u00f5nnestunud kiirendada teatud operatsioone, mis on seotud video dekodeerimisega. Assembleri koodi j\u00f5udluse kasv AVX-512 instruktsioonidega oli vastavalt 94, 44, 64 ja 4,24 korda v\u00f5rreldes baasteostusega, mis on kirjutatud C keeles ilma SIMD-instruktsioonide kasutamiseta. Assembleri koodi, mis on optimeeritud AVX-2 instruktsioonide p\u00f5hjal, j\u00f5udluse t\u00f5us oli vastavalt 67, 27, 55 ja 4,38 korda, samas kui SSSE3 instruktsioonide alusel oli see 40, 21, 29 ja 2,49 korda. Muudatused on lisatud dav1d raamatukogusse, mis pakub alternatiivset dekooderit AV1 video kodeerimisformaatide jaoks. AVX-512 instruktsioonid on saadaval AMD protsessorites, mis p\u00f5hinevad Zen 4 ja 5 mikroarhitektuuridel, samuti Intel protsessorites, mis p\u00f5hinevad sellistel mikroarhitektuuridel nagu Skylake-X, Ice Lake, Tiger Lake ja Rocket Lake.
