Phakathi kwezici ezahlukahlukene ezincomekayo, ipulatifomu yokusakaza bukhoma ye-HTTP isebenzisa i- ukusakaza okuguqukayo ubuchwepheshe obubheke ababhalisile bokusakaza ngokubanikeza kokubili okufunwayo nezinsizakalo zokusakaza bukhoma kuwo wonke amadivayisi we-Apple.

Kungani sidinga ukufuna ubuchwepheshe beHLS Player?

Ngaphambi kokuthi sifinyelele ebhandeni lokusebenzisa i- Umdlali we-HLS ake siqale sibone izizathu eziyinhloko zokuthi kungani umuntu kufanele ayisebenzise kwasekuqaleni.

  • Ukuvumelana - Umdlali we-HLS inokutholakala yonke indawo exhasa ngokoqobo zonke iziphequluli kufaka phakathi kepha kungakhawulelwe ku-Quicktime, Safari, iziphequluli ze-Google Chrome, amapulatifomu e-Microsoft Edge, iLinux neMicrosoft okwenza i-HLS ikhethe kahle phakathi kwabancintisana nabo. 
  • Indlela eqondile - Ukusakazwa kwe-HLS kuletha okuqukethwe komsindo nevidiyo kwi-inthanethi ngendlela engenamthungo. Iningi lesevisi yesidlali sevidiyo esakazwayo etholakala emakethe namuhla kudingeka ukuthi idlule ochungechungeni lokuhamba komsebenzi kusuka ekucushweni kwehadiwe kuye ekufakweni kwesoftware kepha ngakolunye uhlangothi Ukusakaza kwe-HLS ihanjiswa kuwo wonke amadivayisi ngamafayela we-M3U8. Amafayela e-M3U8 aqukethe indawo yefayela yemidiya kwifomu yohlu lwadlalwayo, lapho igcinwa khona njengendlela yefayela emshinini wendawo kanye ne-URL yokusakazwa bukhoma.

Abadlali be-HLS babhekwa njengomunye wabahamba phambili amapulatifomu okusakaza ividiyo lapho abasebenzisi bangathola khona ikhwalithi ephelele yesithombe ngosizo lwalobu buchwepheshe be-HLS kuma-bitrate aphansi futhi futhi ingaletha okuqukethwe kwevidiyo okusakazwa bukhoma kwe-Html5 ngendlela engenamthungo. Ngakho-ke, ubuchwepheshe be-HLS buhlala buyizinga legolide lokusakazwa bukhoma komsindo kanye nokuqukethwe kwevidiyo.
  2. Multiple Ifomethi Player - Esikhathini nosuku lwanamuhla, isidlali sevidiyo esisakazwayo kufanele sikwazi ukuletha okuqukethwe ngekhwalithi enhle kakhulu noma ngabe amadivayisi angabukwa abaluleke kangakanani. I-HLS idlala inqubo yamanje yokusakaza yokusakazwa kwemidiya esebenzisa ubuchwepheshe besimanje. Ukusakazwa kwe-HLS kuya kuma-Smartphones, amaphilisi, ama-PC kanye namanye amadivayisi kunoma yimaphi amafomethi afana ne-MP4, M3U8 noma i-MPEG dash noma kunoma iyiphi enye ifomethi.

Ukubhalwa ngekhodi kwe-HD kwe-Multi-bitrate - Ubuchwepheshe be-HLS busebenzisa ngempumelelo ubuchwepheshe be-multi-bitrate encoding lapho umthombo wevidiyo ulungiselelwe futhi ufakwe kuma-bitrate ahlukahlukene futhi usakazwa kwi-Content Development Network ekhethiwe. Lolu hlobo lwe-multi-bitrate noma imifudlana eminingi lwenza lezi zidlali zokusakaza zevidiyo zivele phakathi kwezincintisana nabo. Lokhu futhi kwenza ababukeli bakwazi ukukhetha ukusakaza ngokuya komkhawulokudonsa wabo ngendlela engenamthungo. Isibonelo, uma isibukeli sinomkhawulokudonsa ophakeme, angakhetha i-1080p60 noma ye-bandwidth emaphakathi angakhetha i-480p noma i-360p njalonjalo.
