AV1 Isiguquli

Tshintsha AV1 ukuya nokubuya kwiifomathi ezahlukeneyo

Malunga AV1

I-AV1 yifomathi yocinezelo yevidiyo evulekileyo, engenabukhosi eyenzelwe ukusasazwa kwevidiyo ngokufanelekileyo kwi-intanethi. Ibonelela ngokusebenza kakuhle koxinzelelo ngaphandle kokubeka esichengeni umgangatho wokubonwayo.

AV1 ichaza indlela omfanekiso ocinezelweyo ngayo; ayithethi nto malunga nendlela ethe i-bitstream igcinwa ngayo kwi diski, kwaye ifuna isiqulathi esijikelezayo phambi kokuba umdlali ayicofe. Iifayile ezilabelwe AV1 kwimisebenzi ziyi-bitstream ngaphakathi kwee-wrapper eziqhelekileyo, kwaye uguqulelo luthetha utshintsho lwe-wrapper, i-codec, okanye zombini.

Oku kwenza ukuba igqibelele ekunikezeleni kwaye ingaphawulwanga nantoni na enye - iisixhobo zokuhlela, ii galleries zefowuni kunye neesixhobo ezidala zihlala ziyi ignore. Ukuguqula kwifomati yomsebenzi oqhelekileyo yenza ukuba imixholo elayishwe ezantsi isebenziseke ngaphandle kwe web. AV1 ibonelela nge-30% yoxinzelelo olungcono kune-H.264 kwinqanaba elifanayo lomgangatho kwaye ayikho iindleko zelayisensi, oko kukuthi, iYouTube ne-Netflix iqhuba.
