Jaromir Miko Uma kukhulunywa ngokwenza kahle, singasho ngekhanda elipholile ukuthi iSafari iyisiphequluli esilungiselelwe kahle kakhulu se-Mac. Noma kunjalo, kunezimo lapho kungeyona inketho engcono kakhulu, futhi esinye salezo zimo ukubuka ividiyo ku-YouTube. I-Retina isiba yizinga elisha futhi singayithola kuwo wonke amadivayisi ngaphandle kwe-iMac eyisisekelo engu-21,5″. Nokho, awukwazi ukujabulela ividiyo ku-YouTube ngokulungiswa okuphezulu kune-Full HD (1080p).
Kungaba njalo okuthakaselayo
Amaya Toman Abasebenzisi abafuna ukujabulela ividiyo ngekhwalithi ephezulu noma ngokusekelwa kwe-HDR kufanele basebenzise isiphequluli esihlukile. Kodwa kungani kunjalo? Kungenxa yokuthi amavidiyo e-YouTube manje asebenzisa ikhodekhi engasekelwa yi-Safari, kungakapheli ngisho neminyaka emithathu i-YouTube iyisebenzise.
Ngesikhathi lapho i-codec ye-H.264 isindala ngempela futhi kwase kuyisikhathi sokuyishintsha kufakwe entsha, kwavela izixazululo ezimbili ezintsha. Esokuqala singumlandeli wemvelo we-H.265 / HEVC, eyonga kakhulu futhi engagcina ikhwalithi yesithombe efanayo noma ephakeme nakakhulu ngenani elincane ledatha. Ifaneleka kakhulu futhi ividiyo ye-4K noma ye-8K, ngenxa yokucindezela okungcono, amavidiyo anjalo alayisha ngokushesha. Ukusekelwa kwebanga lombala eliphakeme (i-HDR10) kuwukuqweqwedisa nje kwekhekhe.
I-Safari isekela le codec kanjalo nezinsiza ezifana ne-Netflix noma i-TV+. Kodwa-ke, i-Google yanquma ukusebenzisa i-codec yayo ye-VP9, eyaqala ukuthuthuka njengezinga lesimanje futhi elivulekile ngokuyinhloko nabanye ozakwethu abambalwa. Lapho kukhona umehluko obalulekile: I-H.265/HEVC ilayisensi, kuyilapho i-VP9 imahhala futhi namuhla isekelwa iziphequluli eziningi ngaphandle kwe-Safari, manje esitholakala kuphela ku-Mac.
I-Google - futhi ikakhulukazi iseva efana ne-YouTube - ayinaso isizathu sokunikeza ilayisense ubuchwepheshe obufana ngezindlela eziningi lapho inganikeza abasebenzisi isiphequluli sayo (Chrome) futhi abasebenzisi bangajabulela i-inthanethi ngokubonga kwayo ngokugcwele. Ngakho-ke igama lokugcina lilele ku-Apple, okungekho lutho oluyivimbelayo ukuthi iqale ukusekela izinga elivulekile ngendlela ye-VP9. Kodwa namuhla akanaso isizathu sokwenza kanjalo.
Sesifinyelele iqophelo lapho i-codec ye-VP9 ithathelwa indawo yizinga elisha le-AV1. Ivuliwe futhi futhi i-Google ne-Apple babamba iqhaza ekuthuthukisweni kwayo. I-Google yaze yaqeda ukuthuthukiswa kwe-codec yayo ye-VP10 ngenxa yayo, okusho okuningi. Ukwengeza, inguqulo yokuqala ezinzile ye-codec ye-AV1 yakhululwa ngo-2018, futhi kuseyindaba yesikhathi ngaphambi kokuba i-YouTube ne-Safari ziqale ukuyisekela. Futhi ngokusobala yilapho abasebenzisi beSafari bezobona khona ukusekelwa kwevidiyo okungu-4K no-8K.
Besikhuluma ngani sonke lesi sihloko?
Uke wazama ukuyifunda? Noma okungenani isihloko?
uneminyaka emingaka ??♂️
Mayelana neqiniso lokuthi imahhala nokuthi i-Apple iyanuka, ngakho-ke angathanda ukungayisebenzisi.
