Tomas Chlebek Embukisweni walo nyaka weNational Association of Broadcasters (NAB), i-Adobe yethule izici ezintsha namakhono eFlash Media Server yayo. Enye yezinto ezintsha ukuhambisana namadivayisi angaphansi kokubusa kwe-iOS.
USteve Jobs wasiqinisekisa kudala ukuthi amagama athi Flash nelithi iOS akufanele abe emshweni ofanayo, ngakho u-Adobe wavuma futhi wengeza ukusekelwa kokusakazwa bukhoma kwe-HTTP ku-Flash Media Server.
Kuyiphrothokholi ethuthukiswe i-Apple ukuze isakazwe bukhoma namavidiyo angekho bukhoma ngoxhumano olujwayelekile lwe-HTTP esikhundleni se-RTSP, okunzima kakhulu ukuyilungiselela. Isebenzisa ividiyo ye-H.264 nomsindo we-AAC noma we-MP3 opakishwe ezingxenyeni ezihlukene zokusakaza kwe-MPEG-2, kanye nezinhla zokudlalayo ze-m3u ezisetshenziselwa ukwenza ikhathalogi izingxenye ngazinye zokusakaza. Le fomethi ingadlalwa yi-QuickTime ku-Mac OSX, futhi kumadivayisi we-iOS iwukuphela kwefomethi yokusakaza abangayiphatha.
U-Apple uhlongoze Ukusakazwa bukhoma kwe-HTTP ku-IETF Internet Standards Committee emuva ku-2009, kodwa kuze kube manje akukaze kube khona inkomba yokuthi lesi siphakamiso sizoqhubekela phambili. Kodwa iMicrosoft isangeze ukwesekwa kuseva yayo ye-IIS Media Services, esetshenziselwa ukuletha ividiyo esakazwayo kumakhasimende asekelwe eSilverlight. Uma i-IIS Media Services ithola idivayisi ye-iOS, okuqukethwe kuyapakishwa futhi kusakazwe kusetshenziswa ukusakazwa bukhoma kwe-HTTP.
Ngonyaka odlule, i-Adobe yengeze isici sayo sokusakaza se-HTTP ku-Flash Media Server. Ifana ne-Apple endleleni ecubungula ngayo ividiyo ye-H.264, lapho ividiyo ihlukaniswa futhi igcinwe kumafayela ahlukene, ngemva kwalokho ithunyelwa nge-HTTP kobhalisile okuzenzakalelayo. Kodwa endabeni ye-Adobe, i-HTTP Dynamic Streaming isebenzisa ifayela le-XML (esikhundleni sohlu lwadlalwayo lombhalo) kanye ne-MPEG-4 njengesiqukathi. Ngaphezu kwalokho, ihambisana kuphela ne-Flash noma i-AIR.
Ngamazwi omphathi omkhulu womkhiqizo weFlash Media Server uKevin Towes, i-Adobe inentshisekelo yokuthuthukisa ubuchwepheshe ukuze kube lula inqubo yokusakaza, okuholela ekufakweni kalula kwezinhlobonhlobo zamadivayisi. Ukhulume kubhulogi ukuthi i-Adobe yengeza ukusekelwa kokusakazwa bukhoma kwe-HTTP kweFlash Media Server kanye neFlash Media Live Encoder. Wabhala ukuthi: "Ngokungeza ukusekelwa kwe-HLS ngaphakathi kwe-Flash Media Server, i-Adobe yehlisa inkimbinkimbi yokushicilela kulabo abadinga ukufaka iziphequluli ezisebenzisa i-HLS nge-HTML5 (isb. Safari), noma amadivayisi angenayo i-Adobe Flash.”
Ngakho i-Adobe yenza uhlobo oluthile lokuyekethisa, lapho ingafuni ukulahlekelwa abasebenzisi abangaba abasebenzisi beFlash Media Server futhi ngesikhathi esifanayo ikholise i-Apple ukuthi isekele i-Flash kumadivayisi we-iOS, ngakho-ke icabangela isidingo sokusakaza ividiyo ngisho nangaphandle kweFlash.
Ukusakaza bukhoma kwe-HTTP kuzophinde kutholakale kwezinye izinkundla, okuhlanganisa iSafari ku-Mac OS X. Esinye sezizathu zale ndlela kungaba ukuthi i-Apple ithengisa i-MacBook Airs yakamuva ngaphandle kwe-Flash efakwe ngaphambili. Nakuba isizathu esiyinhloko salokhu siwukuqedwa kwesidingo sokubuyekeza le elementi ngemva kokwethulwa kokuqala, kuphinde kwaziwe kabanzi ukuthi iFlash inciphisa kakhulu ukuphila kwebhethri (kufika ku-33% kuMacBook Air eshiwo ngenhla).
Yize i-Adobe ithi isebenza enguqulweni yeFlash elungiselelwe iMacBook Air, lesi sinyathelo esishiwo ngenhla sigcina abasebenzisi abangafuni ukufaka iFlash.

Ukuthi ekugcineni kuzokwazi ukubuka amavidiyo we-flash ku-iOS...
Uma kunjalo, ngingaya ku-iPad 2
Uma kuvela ukuthi kuyiqiniso, i-iPad ngeke ibe nokuncintisana ngempela (impela kuyoba, kodwa encane, ngokubona kwami, kuwukufisa okuncane, sizobona i-Flash ku-iOS mhlawumbe isigamu sonyaka). , noma eminyakeni eyi-10 ngethemba, okungenani kungakapheli unyaka.
"I-Flash inciphisa kakhulu impilo yebhethri (esimweni se-MacBook Air eshiwo ifinyelela ku-33%). Ngalokhu usho ukuthi uma kusetshenziswa i-flash, impilo ye-macbook izokwehla ngo-33% (kuyi-falsh egijima) noma umthamo webhethri uzokwehla unomphela ngo-33% nakuba mhlawumbe i-flash inganikezi (ngenxa yobuhle, kodwa ibhalwe kanjalo)?
Uma othile eshoda ngamavidiyo e-flash, faka i-SkyFire... isebenza ku-iPad ne-iPhone yami ngaphandle kwenkinga;)
