AV1 Isiguquli

Guqula AV1 kuya futhi kusuka kumafomethi ahlukahlukene

Mayelana AV1

I-AV1 iyifomethi yokuminyanisa ividiyo evulekile, engakhokhelwa eyenzelwe ukusakazwa kahle kwevidiyo nge-inthanethi. Inikeza ukusebenza kahle kokucindezela okuphezulu ngaphandle kokuyekethisa ikhwalithi yokubuka.

AV1 Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini ihele levidiyo AV1?

AV1 yividiyo codec hhayi isiqoqi - ichaza indlela ifreyimu ngayinye ekhodwe ngayo. AV1 ivame ukuboshwa ngaphakathi kwesiqoqi njenge MP4 noma MKV uma igcinwa kwidiski.

Ingabe AV1 yi-codec noma ifomethi yehele?

I-codec, ngakho-ke impendulo ku "ungayivula kanjani" ayisoze yashesha. AV1 ichaza ukuthi isithombe sicindezelwe kanjani; ayisho lutho mayelana nokuthi i-bitstream igcinwa kanjani kwidiski, futhi idinga isikhala esingaphansi kwayo ngaphambi kokuba umdlali ayichofoze. Amafayela aphawulwe AV1 ngokuvamile yi-bitstream ngaphakathi kwe-wrapper ejwayelekile, futhi ukushintsha kuvame ukusho ukuguqula i-wrapper, i-codec, noma zombili. AV1 yi-video codec engekho emthethweni ye-Alliance for Open Media ekhishwa ngo-2018 njengengxenye yokulandela i-VP9.

Kungani okuqukethwe kwewebhu kuthunyelwe njenge AV1?

Ngokuba ifakwe ngokukhethekile le misebenzi: amafayela amancane, ukuqala ngokushesha, akukho plug-in futhi akukho layisense lokukhathazeka. Lokhu kwenza kube ngcono ekunikezelweni futhi kungaphawuleka nganoma yini enye - amathuluzi okuhlela, ama-gallery wefoni namadivayisi adala ahlala ekhohlwa. Ukushintsha ifomu elijwayelekile-lomsebenzi yilokho okukwenza okuqukethwe okuthunyelwe kusebenziseke ngaphandle kwe-web. AV1 inikeza cishe 30% engcono ucindezelo kuna H.264 esezingeni elifanayo futhi ithatha akukho izinkokhelo izitifiketi, okuyinto kungani YouTube ne Netflix push it.

Ingabe ngidlala AV1 ku-tab yesiphequluli ngaphandle kokufaka noma yini?

Yebo — AV1 yisinye sezifomethi zevidiyo ezincane ezixhunywe ku-browser, ngakho-ke ukushaya ifayela kwi-tab noma ukulifaka kukhasi kusebenza kuphela kudesktop neselula. Lokhu kwenza kube yisinqumo esifanele sokudlalwa okuzenzakalelayo kwekhasi lewebhu, futhi yisizathu sokuguqulwa kulolu hlobo lwefayela kuvame ukuxazululwa ngokushesha "ividiyo ayizodlala kuwebhusayithi yami".

Kungani i-AV1 idlala ngokugcizelela noma isebenza ngokufudumele kuma-machines adala?

Ngenxa yokuthi i-software ifakazela. Ama-hardware video decoders afakazela kuphela uhlu oluqinile lwefomethi, futhi AV1 ungaphandle kwayo kumadivayisi amaningi, ngakho-ke yonke ifreyimu ivuselelwa yi-CPU endaweni. Kudesktop yamanje elahlekile; ku-smartphone, i-laptop edala noma i-smart TV ivela njengefreyimu elahlekile, umsindo we-fan nebhethri eliphumayo. Ukudlulisa ku-hardware-supported format isusa izinkinga zonke. AV1 yi-codec, hhayi isiqoqi — i-bitstream ihamba ngaphakathi MP4 noma WebM, ixhunywe ne-Opus noma i-AAC umsindo.

Ingabe izihloko ezingezansi ngaphakathi kwe AV1 zingakhethwa, noma ziboshwe ngaphakathi kwesithombe?

Kukhethwa, uma kufakwe kahle. AV1 ifaka izihloko ezingezansi njengemithombo yabo ehlukile engezansi kwevidiyo, ngakho-ke umbukeli angashintsha ulwimi, azicishe, noma aphinde aphinde asebenzise izihloko ezingezansi kumdlali oxhasa lokhu. Izihloko ezingezansi ezibomvu zingasetshenziswa — ziyi-pixels kuphela kwifreyimu — kodwa zihlala njalo, futhi kungekho sizathu sokukhetha uma isiqukathi sixhasa into engokoqobo.

Ingabe AV1 ikhona futhi ikhona ukuxhaswa okubanzi?

Kuncane njalo ngonyaka, kodwa ibanga liyiqiniso. Usizo lwesofthiwe lwafika ngokushesha; usizo lwehardware luvela kuphela ngezinto ezintsha, futhi ifoni, i-TV noma umdlali phambi kwakho ungase uqale ngokulula. lapho kuxhaswa khona kungcono kakhulu kunalokho okuhlobene nohlelo olushintshayo, ngakho-ke kufanelekile ukushintshana ukuze kuthunyelwe futhi kufanelekile ukushintshana ngaphandle kokusebenza.

Ingabe ihele AV1 ligcina ama-tracks omsindo amaningi?

Yebo - imixholo yesiNgisi, i-dub ne-comment ingahlala yonke kwifayela elilodwa ne-player eshintsha phakathi kwazo. Izinqumo ezimbili: amafoni amaningi nama-television adlalayo abonisa kuphela umculo wokuqala kodwa amanye akhona, futhi ukuguqulwa kufomethi ngaphandle kosizo olukhulu lwe-tracks agcina umculo owodwa futhi akhuphula okunye. Khetha umculo ofuna ngaphambi kokuguqula, ngaphezu kokubheka emuva ukuthi iyiphi ehlala.

Kungani uguqula i-AV1 ibe yifomethi yevidiyo?

Gcina AV1 MP4 uma ufuna ukusakaza jikelele - web browsers, amadivayisi eselula, smart TVs kanye nokuhlela amathuluzi wonke adlala MP4 natively. Gcina WebM for web embedding lapho ncane ifile size izinto. Gcina MOV uma usebenza Final Cut noma ezinye Apple-native pipelines. AV1 encoding ihamba kancane, futhi amathuluzi decoders kuphela wavela kumafoni namahlaya kusukela mayelana 2020 kuqala - amadivayisi adala buyela amandla-ukudla isofthiwe decoding.

Ingabe ukuguqulwa kwe-AV1 kuphinde kuhlanganise ividiyo?

Uma umsuka we-codec ngaphakathi AV1 uhambisana ne-container ethengiswayo sizoyi-remux ngaphandle kokuphindeka kokufaka ikhowudi (ikhawulela, ingekho lutho olulahlekile). Uma i-codec idinga ukuguqulwa (njenge-HEVC kuya ku-H.264) ividiyo iphindeka ukufakwa ikhowudi — ihamba kancane, ngezindleko ezincane zobuhlobo bosuku.
