Kwiintsuku ezithile ezidlulileyo Indawo yaseVideoLAN kunye ne-Ffmpeg ityhilwe ukukhutshwa kwenguqulelo entsha yethala leencwadi I-dav1d 0.6.0. Olu lolunye ulwazelelo lokumiliselwa kwasimahla kwifomathi yekhowudi ye-AV1.
Ithala leencwadi le-dav1d lixhasa onke amanqaku e-AV1, kubandakanya ukuhla kweesampulu ezisezantsi kunye nayo yonke imilinganiselo yokulawulwa kobunzulu bemibala ebhengezwe kwinkcazo (8, 10 kunye ne-12 bit). Ithala leencwadi lavavanywa kwingqokelela enkulu yeefayile kwifomathi ye-AV1.
Malunga nekhowudi yedav1d
Ikhowudi yevidiyo I-AV1 yaphuhliswa yi-Open Media Alliance. (AOMedia), apho iinkampani ezinje ngeMozilla, Google, Microsoft, Intel, ARM, NVIDIA, IBM, Cisco, Amazon, Netflix, AMD, VideoLAN, CCN kunye neRealtek zimelwe
AV1 ibekwe njengefomathi yasimahla yokufomatha ividiyo engadingi kuhlawulwa, ephezulu ngokubonakalayo kwi-H.264 kunye ne-VP9 ngokwe-compression.
Isalathiso seekhowudi sesalathiso se I-AV1 ilungile, kodwa ikhowudi yekhowudi, ke inintsi into yokuphucula. Kungenxa yoko le nto i-VideoLAN, i-VLC kunye ne-FFmpeg yoluntu luqale ukusebenza kwi-decoder entsha, exhaswa yi Umdibaniso weMidiya evulekileyo, Ukwenza ireferensi elungiselelwe i-AV1.
Eyona nto iphambili kwi-dav1d kukugxila kwayo ekufezekiseni intsebenzo Ukucaciswa kwenqanaba kunokwenzeka kunye nokuqinisekisa ukusebenza komgangatho ophezulu ngemisonto emininzi.
Umsebenzi wethala leencwadi wavavanywa kwingqokelela enkulu yeefayile kwifomathi ye-AV1. Eyona nto iphambili kwi-dav1d kukugxila kwayo ekufezekiseni owona msebenzi uphezulu ukumisela ikhowudi kunye nokuqinisekisa umgangatho ophezulu womsebenzi kwimowudi yokufunda emininzi.
Injongo yale dekhowudi intsha yile:
- Ukuze ube mncinci
- ngokukhawuleza okukhulu
- Bonelela ngenkxaso yeqonga
- Imisonto efanelekileyo,
- Isimahla kwaye (eneneni) umthombo ovulekileyo.
Ikhowudi yeprojekthi ye-dav1d ibhaliwe kwi ulwimi lwenkqubo C(C99) kwaye ikwanokufakwa kwezinto (NASM / GAS) kwaye isasazwa phantsi kwelayisensi ye-BSD. Idikhoda ibala ngenkxaso ephunyeziweyo ye-x86, x86_64, ARMv7 kunye ne-ARMv8 yoyilo kunye neLinux, Windows, macOS, Android, kunye neenkqubo zokusebenza ze-iOS.
Iimpawu ezintsha eziphambili ze-dav1d 0.6.0
Inguqulelo entsha yedikhowuda I-dav1d 0.6.0 ilungisa ezinye iibugs ezazikho kuhlobo lwangaphambili, kunye nabaphuhlisi baphumeze ulungiselelo ngqo Uyilo lwe-ARM64 Bagubungela imisebenzi emininzi xa besebenza ngobunzulu bemibala eli-10 kunye ne-12.
Ikwaqaqambisa umsebenzi owenziweyo ukongeza ulungiselelo olusekwe kwimiyalelo ye-SSSE3 yokunciphisa ingxolo yedijithali kunye nokwenza ngcono okusekwe kwimfundo I-AVX2 yokusebenza msac_adapt16.
Olunye ulungiselelo olwenziweyo kolu hlelo lutsha zezi iluphu, i-cdef, kunye ne-msac yokubuyisela ukusebenza kokuphuculwa kwe-ARM64 kunye nokuphucula ukulungiswa kwe-AVX2 ye-cdef_filter.
Kwelinye icala, kuyakhankanywa kwisibhengezo sokuba abaphuhlisi basebenze ngokongeza ukulungiswa ngokusekwe kwi-AVX-512 imiyalelo ye-prep_bilin, prep_8tap, cdef_filter kunye ne-mc_avg / w_avg / imask.
Kwinxalenye yezilungiso kukhankanyiwe ukuba ukungangqinelani okungafaniyo okungafaniyo kwindlela yokuziphatha kunye nedikhodi ireferensi ye-AV1 kunye nokuba uphuculo lwenziwe kwimisebenzi ye-itxfm kunye ne-cdef_filter kwi-C.
Gqibela ukuba ufuna ukwazi ngakumbi ngayo malunga nale nguqulo intsha kunye neprojekthi yale dekhowudi, ungajonga iinkcukacha Kule khonkco ilandelayo.
Uyifaka njani i-dav1d kwi-Ubuntu nakwiziphumo?
Kulabo banomdla wokukwazi ukufaka le khowudi kwiinkqubo zabo, banokwenza oko ngokulandela imiyalelo esabelana ngayo ngezantsi.
Ngokubanzi kuninzi lonikezelo lweLinux, abafana abavela kwiprojekthi yeVideoLan, banikela Iphakheji yekhowudi ngokusebenzisa iphakheji ye-Snap.
Ke ngoko ukuyifaka ngale ndlela, kufuna kuphela ukuba unikezelo lwakho lunenkxaso yolu hlobo lweephakeji.
Kwisiphelo kufuneka benze lo mthetho ulandelayo:
sudo snap install dav1d --edge
