Mamwe mazuva apfuura iyo VideoLAN uye Ffmpeg nharaunda dzakafumurwa kuburitswa kweshanduro nyowani yeraibhurari dav1d 0.6.0. Iyi ndiyo imwe yemahara yemodhiyo yekumisikidza yeAV1 vhidhiyo yekukodha fomati.
Iyo dav1d raibhurari inotsigira ese maficha eAV1, inosanganisira epamberi ekudzikisa mhando uye ese akadzika mavara kudzora paramende yakaziviswa mune yakatarwa (8, 10 uye 12 bit). Raibhurari yakaedzwa pane hombe muunganidzwa wemafaira muAV1 fomati.
Nezve iyo dav1d decoder
Vhidhiyo codec AV1 yakagadzirwa neOpen Media Alliance. (AOMedia), mune makambani akadai seMozilla, Google, Microsoft, Intel, ARM, NVIDIA, IBM, Cisco, Amazon, Netflix, AMD, VideoLAN, CCN uye Realtek inomiririrwa.
AV1 yakamisikidzwa semahara yekuwana vhidhiyo encoding fomati iyo isingade kubhadharwa kwemari, iyo inonyanya kukwirira kupfuura H.264 uye VP9 maererano nekomputa.
Referensi decoder ye AV1 yakanaka, asi ndeyekutsvagisa codebase, saka ine zvakawanda zvekuvandudza. Ndosaka iyo VideoLAN, VLC uye FFmpeg nharaunda dzakatanga kushanda padhodhi nyowani, inotsigirwa neiyo Mubatanidzwa we Open Open, kugadzira referensi yakagadziridzwa decoder yeAV1.
Chinhu chakakosha chedav1d kutarisisa pakuita mashandiro kududzira chiyero chinogoneka uye nekuona yepamusoro-mhando multithreaded mashandiro.
Basa reraibhurari rakaedzwa pane hombe muunganidzwa wemafaira muAV1 fomati. Chinhu chakakosha chedav1d ndiko kutarisisa mukuwana kuita kwakanyanya kuita kududzira uye kuverengera yemhando yepamusoro basa mumamita akawanda akaverengwa.
Chinangwa cheichi chitsva dhodhi ndechekuti:
- Kuti uve mudiki
- kurumidza sezvinobvira
- Ipa rutsigiro rwechinjika-chikuva
- Yakarukwa zvakanaka,
- Yemahara uye (chaizvo) yakavhurwa sosi.
Iyo dav1d kodhi yeprojekiti yakanyorwa mu programming mutauro C(C99) uye zvakare ine inosangana inosunga (NASM / GAS) uye inogoverwa pasi peBSD rezinesi. Decoder anoverenga ine yakatsigirwa rutsigiro rwe x86, x86_64, ARMv7 uye ARMv8 zvivakwa uye Linux, Windows, macOS, Android, uye iOS anoshanda masisitimu.
Main nyowani maficha e dav1d 0.6.0
Iyi itsva vhezheni yedhisodhi dav1d 0.6.0 inosvika kugadzirisa mamwe mabugs izvo zvaivapo mushanduro yapfuura, pamwe nevakagadziri vakaita optimizations chaiyo ARM64 kuvaka Ivo vanofukidza akawanda mashandiro pavanenge vachishanda ne10 ne12 bit bhuru kudzika.
Zvakare inosimbisa iro basa rakaitwa kuwedzera optimizations zvichibva pane SSSE3 mirairo yekudzora ruzha rwemadhijitari pamwe nekudzidziswa-kwakavakirwa optimizations AVX2 yeiyo msac_adapt16 kushanda.
Mamwe magadziriso akaitwa mune ino nyowani shanduro ndeaya chiuno, cdef, uye msac kudzoreredza mashandiro emabasa eARM64 uye zvakare yakagadziridza AVX2 optimizations ye cdef_filter.
Kune rimwe divi, zvinotaurwa mukuzivisa kuti vanogadzira vakashanda pakuwedzera optimizations zvichibva paAVX-512 mirairo yeiyo prep_bilin, prep_8tap, cdef_filter uye mc_avg / w_avg / mask mashandiro.
Kune chikamu chemagadziriso zvinotaurwa izvo yakagadziriswa isingawanzo mutsauko mukuzvibata ne decoder chirevo AV1 uye kuti kusimudzira kwakaitwa muitxfm uye cdef_filter mashandiro muC.
Finalmente kana iwe uchida kuziva zvakawanda nezvazvo nezve iyi vhezheni nyowani uye zvakare nezve nezve chirongwa cheiyi decoder, unogona kutarisa ruzivo Mune inotevera chinongedzo.
Maitiro ekuisa dav1d decoder pane Ubuntu uye zvigadzirwa?
Kune avo vanofarira kugona kuisa ichi chinodhindaina mumasisitimu avo, vanogona kuzviita nekutevera rairo dzatinogovana pazasi.
Kazhinji yezvakawanda zvekugoverwa kweLinux, ivo vakomana veVideoLan chirongwa, vape iyo decoder pasuru kuburikidza neiyo Snap package.
Saka kuti umise nenzira iyi, zvinongoda kuti kugovera kwako kuve nerutsigiro rwemhando iyi yepakeji.
Mune terminal vanongofanira kuita unotevera kuraira:
sudo snap install dav1d --edge
