Ezinsukwini ezithile ezedlule imiphakathi yeVideoLAN neFfmpeg yethulwe ukukhishwa kwenguqulo entsha yomtapo wezincwadi I-DAV1D 0.6.0.. Lokhu okunye ukuqaliswa kwama-decoder amahhala wefomethi yokufaka ikhodi yevidiyo ye-AV1.
Umtapo wezincwadi we-dav1d usekela zonke izici ze-AV1, kufaka phakathi izinhlobo ezithuthukisiwe zokwehliswa phansi nawo wonke amapharamitha wokulawula ukujula kombala amenyezelwe kuchazwe (8, 10 no-12 bit). Umtapo wezincwadi uvivinywe eqoqweni elikhulu lamafayela ngefomethi ye-AV1.
Mayelana ne-dav1d decoder
Ikhodekhi yevidiyo I-AV1 yenziwe yi-Open Media Alliance. (AOMedia), lapho izinkampani ezifana neMozilla, Google, Microsoft, Intel, ARM, NVIDIA, IBM, Cisco, Amazon, Netflix, AMD, VideoLAN, CCN neRealtek zimelwe khona
AV1 ibekwe njengefomethi yokufaka ikhodi evidiyo yamahhala engadingi ukukhokhwa kwemali, ephakeme kakhulu kune-H.264 ne-VP9 maqondana nokucindezela.
Idikhoda yesithenjwa ye- I-AV1 yinhle, kepha yicodebase yocwaningo, ngakho-ke kuningi okufanele ikuthuthukise. Kungakho imiphakathi yeVideoLAN, VLC kanye neFFmpeg iqale ukusebenza nge-decoder entsha, exhaswa yi- Ukubambisana kwe-Open Media, ukudala i-decoder elungiselelwe ireferensi ye-AV1.
Isici esiyinhloko se-dav1d ukugxila ekufezeni ukusebenza izinga lokukhipha kungenzeka futhi liqinisekise ukusebenza kwekhwalithi ephezulu kakhulu.
Umsebenzi womtapo wezincwadi uvivinywe eqoqweni elikhulu lamafayela ngefomethi ye-AV1. Isici esiyinhloko se-dav1d ukugxila ekufinyeleleni ukusebenza okuphezulu kakhulu emagama ekucinisekeni nekucinisekiswa kwelizinga lelisetulu kwemsebenti kumodi lefundvwako.
Umgomo wale dekhoda entsha yile:
- Ukuze ube mncane
- shesha ngangokunokwenzeka
- Nikeza ukwesekwa kwepulatifomu
- Ifakwe kahle,
- Umthombo ovulekile futhi (empeleni) ovulekile.
Ikhodi yephrojekthi ye-dav1d kubhalwe ngesi- ulimi lokuhlela I-C (C99) futhi inokufakwa okuhlanganayo (i-NASM / GAS) futhi kusatshalaliswa ngaphansi kwelayisense le-BSD. Idikhoda iyabalwa ngokusekelwa okusetshenzisiwe kokwakhiwa kwe-x86, x86_64, ARMv7 ne-ARMv8 kanye nezinhlelo zokusebenza zeLinux, Windows, MacOS, Android, kanye ne-iOS.
Izici ezintsha eziyinhloko ze-dav1d 0.6.0
Le nguqulo entsha yedikhoda I-dav1d 0.6.0 ilungisa ezinye izimbungulu ezazikhona enguqulweni edlule, kanye nabathuthukisi basebenzise ukulungiselelwa ethize Ukwakhiwa kwe-ARM64 Zimboza imisebenzi eminingi lapho zisebenza ngokujula kombala okungu-10 no-12.
Futhi kugqamisa umsebenzi owenziwe ukwengeza ukulungiselelwa okususelwa kumiyalo ye-SSSE3 yokwehlisa umsindo wedijithali kanye nokwenza ngcono okususelwa ekufundiseni I-AVX2 yokusebenza kwe-msac_adapt16.
Okunye ukulungiselelwa okusetshenziswe kulolu hlobo olusha yi- iluphu, i-cdef, ne-msac buyisela ukuthuthukiswa kokusebenza kwe-ARM64 futhi ngithuthukise nokwenza ngcono kwe-AVX2 kwe-cdef_filter.
Ngakolunye uhlangothi, kuyakhulunywa kusimemezelo sokuthi abathuthukisi basebenze ekungezeni ukwenziwa okulungiselelwe ngokususelwa kumiyalo ye-AVX-512 yokusebenza kwe-prep_bilin, prep_8tap, cdef_filter kanye ne-mc_avg / w_avg / mask.
Engxenyeni yokulungiswa kushiwo lokho ukulungisa ukungafani okungajwayelekile kokuziphatha ne-decoder ireferensi i-AV1 nokuthi ukwenziwa ngcono kwenziwe ekusebenzeni kwe-itxfm ne-cdef_filter ku-C.
Okokugcina uma ufuna ukwazi kabanzi ngayo mayelana nale nguqulo entsha futhi mayelana nephrojekthi yale dekhoda, ungabheka imininingwane Kulesi sixhumanisi esilandelayo.
Ungayifaka kanjani i-dav1d decoder ku-Ubuntu nakwezinye izinto?
Kulabo abanentshisekelo yokukwazi ukufaka le-decoder ezinhlelweni zabo, bangakwenza lokho ngokulandela imiyalo esabelana ngayo ngezansi.
Ngokuvamile ekusatshalalisweni okuningi kweLinux, abafana abavela kuphrojekthi yeVideoLan, banikela iphakethe ledekhoda ngokusebenzisa iphakethe le-Snap.
Ngakho-ke ukuyifaka ngale ndlela, kudinga kuphela ukuthi ukusatshalaliswa kwakho kusekelwe kulolu hlobo lwephakeji.
Esigungwini kufanele nje benze umyalo olandelayo:
sudo snap install dav1d --edge
