Paket je napisan na jeziku C i distribuira se pod LGPL i GPL licencama.            <\/p>\n<p>Me\u0111u promjenama u FFmpeg 7.1:   <\/p>\n<ul>\n<li class=\"l\"> Dodani su video enkoderi u formatima H.264 i H.265, koji koriste pro\u0161irenja grafi\u010dkog API-ja Vulkan za hardversko ubrzanje kodiranja video sadr\u017eaja. Po svojim mogu\u0107nostima, enkoderi temeljeni na Vulkan-u identi\u010dni su prethodno dostupnim enkoderima koji koriste VAAPI za ubrzanje.\n<li class=\"l\"> U paket je uklju\u010den vlastiti dekoder za format kodiranja zvuka xHE-AAC (podr\u017eava podskup AAC USAC), koji se koristi u streaming uslugama poput Netflixa i uklju\u010den je u tehnologije digitalnog radija Digital Radio Mondiale. Codec se izdvaja po podr\u0161ci \u0161irokom rasponu bitrate-a (od 12 do 300 kbit\/s), visokom stepenu kompresije, sredstvima reprodukcije s konstantnom glasno\u0107om, osiguravanju visoke jasno\u0107e pri svim nivoima glasno\u0107e, dodatnim profilima upravljanja dinami\u010dkim rasponom prilikom slu\u0161anja u bu\u010dnim okru\u017eenjima i dodavanju metapodataka koji omogu\u0107uju obnavljanje gubitaka na strani korisnika.\n<li class=\"l\"> Objavljena je stabilna implementacija dekodera za format VVC (Versatile Video Coding), poznat i kao standard kompresije video sadr\u017eaja H.266, koji su razvile radne grupe MPEG (ISO\/IEC JTC 1) i VCEG (ITU-T), u suradnji sa kompanijama kao \u0161to su Apple, Ericsson, Intel, Huawei, Microsoft, Qualcomm i Sony. H.266 zamjenjuje H.265 (HEVC) i nudi visoku u\u010dinkovitost prijenosa i pohrane svih razlu\u010divosti ekrana (od SD i HD do 4K i 8K), podr\u017eava video s pro\u0161irenim dinami\u010dkim rasponom (HDR, High Dynamic Range) i panoramski video u re\u017eimu 360 stupnjeva.\n<li class=\"l\"> Dodana je mogu\u0107nost ubrzanja dekodiranja VVC-a kori\u0161tenjem Intel QSV (Quick Sync Video) tehnologije.\n<li class=\"l\"> Dodao je VVC enkoder, implementiran kroz kori\u0161tenje biblioteke libvvenc.\n<li class=\"l\"> Implementirana je mogu\u0107nost dekodiranja videa u formatu MV-HEVC (Multiview High Efficiency Video Coding), koji se koristi u virtualnim stvarnostima i na pametnim telefonima za prijenos stereoskopskog videa.\n<li class=\"l\"> Dodana je dekoder za LCEVC standard video kodiranja, implementiran na temelju vanjske biblioteke LCEVCdec. LCEVC dodaje dodatni sloj s metapodacima za pobolj\u0161anje kvalitete ve\u0107 postoje\u0107ih H.26x i MP4\/ISOBMFF kodeka.\n<li class=\"l\"> U muxer-ima za medijske kontejnere Matroska i MP4\/MOV implementirano je analiziranje i zapisivanje metapodataka o rezanju videa (npr. prilikom prikazivanja na ekranima s razli\u010ditim omjerima stranica).\n<li class=\"l\"> Dodana je podr\u0161ka za kodiranje i dekodiranje zvuka u LC3 i LC3plus formatima, optimiziranim za be\u017ei\u010dni prijenos zvuka s minimalnim ka\u0161njenjem (npr. koristi se u Bluetooth slu\u0161alicama). Implementacija se temelji na vanjskoj biblioteci liblc3. Dodani su dekoderi i enkoderi medijskih kontejnera za LC3 i LC3plus.\n<li class=\"l\"> Dodana je podr\u0161ka za dekodiranje zvuka u AAC, AMR-NB, AMR-WB i MP3 formatima koriste\u0107i MediaCodec API koji pru\u017ea Android platforma.\n<li class=\"l\"> Dodan je D3D12VA HEVC kodirnik, koji implementira hardversko ubrzanje putem D3D12 API-a.\n<li class=\"l\"> Dodan je dekoder titlova u RCWT (Raw
