I-YouTube kunye neVimeo zikhetha i-H.264 codec ngaphezulu kwe-Ogg / Theora

Apha ngezantsi ndivelisa ingxelo kaMozilla malunga nesigqibo esenziwe yiYouTube kunye neVimeo yokukhetha ikhowudi yeH.264 endaweni yeOgg, abasebenzisi beebrawuza ezinje ngeFirefox kunye neOpera benzakaliswa sesi sigqibo, kunye nabo bonke abasebenzisi be-Intanethi ngenxa emngciphekweni welungelo elilodwa lomenzi kwaye kufuneka uhlawule iphepha-mvume lokusetyenziswa, kokubini kuyilwa umxholo kunye nokuboniswa kwayo.

Ingxelo yeMozilla:

Ngaba unokucinga ukuba unako uyonwabele yonke imixholo ekwi-intanethi usebenzisa isikhangeli sakho kuphela? Ngaba uyakwenzaNgaphandle kokufaka usetyenziso olungakumbi, ii-plugins okanye ii-codec? Ewe, leyo yenye yeenjongo zokuba imigangatho emitsha ye-HTML5 enomsindo nevidiyo Kumnatha. Ngoku, Uninzi lwezikhangeli zisebenzisa le tag yevidiyo intsha evumela ukubonisa umxholo wee-audiovisual ngaphandle kwesidingo sayo nayiphi na into, ngaphandle kokusebenzisa iFlash, ngaphandle kokufaka ii-codecs.

Ibali alilihle njengoko kubonakala ngathi sizifumana sinengxaki enkulu, xa umzimba onoxanduva (W3CUkudala isikhombisi se-HTML5 senze idrafti, ichaze ukuba ifomathi yevidiyo kufuneka ingene ithiyori, ikhowudi yevidiyo yasimahla nesimahla yelungelo elilodwa lomenzi, kodwa ezinye iinkampani ezenza i-W3C zakhalaza kakhulu (ngakumbi iApple) njengoko zazinjalo umdla wezoshishino ukusebenzisa ii-codec zazo, kwaye ekugqibeleni akukho khowudi icacisiweyo ukuba isetyenziswe ngethegi "yevidiyo".

Zeziphi iibrawuza eziyiphumezayo?

Njengoko besitshilo ngaphambili, uninzi lwebrowser sele luzalisile le thegi, kodwa elowo uthathe isigqibo sokusebenzisa ikhowudi kule tag, masiyiqhekeze:

• I-Presto / i-Opera: I-HTML5 nge-GStreamer (ibandakanya kuphela i-Ogg / Theora).
• WebKit / Chrome: HTML5 usebenzisa ffmpeg (Ogg / Theora kunye H.264 / MP4).
• I-Gecko / Firefox: HTML5 ene-Ogg / Theora.
• WebKit / Epiphany: HTML5 ngeGStreamer (iOgg / Theora iqinisekisiwe).
• I-WebKit / Safari: I-HTML5 nge-QuickTime (H.264 / MOV / M4V, ingadlala i-Ogg / Theora enezinto zeXiphQT).

Siyabona ukuba abanye bakhethe i-Ogg / Theora codec yasimahla, ngelixa abanye bekhowudi H.264 amalungelo awodwa omenzi wechiza yi-MPEG-LA (yeyiphi iApple neMicrosoft) kwaye ayinakusetyenziswa kwinkqubo eyisebenzisayo ngaphandle kokuhlawula i-MPEG-LA, kwaye ukusukela ngo-2010 konke Nabani na ofuna ukuyisebenzisa (nokuba ulayishe ividiyo ngale codec kwiwebhusayithi yakho) kuya kufuneka hlawula unayo kuhamba yokusetyenziswa, Oko kuthetha ukuba awuzokwazi ukubonisa iividiyo zakho simahla kule fomathi.
Ukubheja kwi-codec engenasimahla kwiwebhu akulunganga kwaye kuyaphula umxholo wento intanethi kwaye ikho, ngokwamazwi ka-Asa Dotzler:

Iwebhu ngekhe ibe yile nto iyiyo namhlanje ukuba yonke ibhlogger kufuneka ihlawule ilayisensi yokuthumela imifanekiso kunye nokubhaliweyo kwiphepha elinye. Iividiyo azizukufuna ukuhlawulwa kwamaphepha-mvume.

Izibuko zemultimedia

Siye sanomothuko kule veki apho kakhulu Youtube indlela uVimeo abhengeze ngayo ukuba bazakuqala ukusebenzisa i-tag ye-HTML5 "yevidiyo" njengenye indlela yokubonisa iividiyo zakho endaweni yeFlash. Uvuyo aluzange luhlale ixesha elide xa sakubona oko baya kuyisebenzisa kuphela kwi-H.264 codec, eshiya uTheora ngaphandle. Izizathu abazinikayo zokungasebenzisi i-codec yasimahla kukuba inomgangatho omncinci kwaye sele benayo yonke into kwi-H.264, esingayiqondiyo oko kwaboniswa ukuba Umgangatho weTheora uyafana ekubonelelwa ngayo ngoku kwi-Youtube kwifayile ye- uthelekiso phakathi kweTheora kunye ne-H.264 kwaye sele kukho abanye abasasazi bomxholo ukuba Bakhethile zeefomati zasimahla ezinje ngevidiyo portal Dailymotion ebonisiweyo amandla ethegi yevidiyo eneekhowudi zasimahla.

Uhlaziyo: La Isiseko seSoftware sasimahla sibuze ukuba sivote kwiphepha lengcebiso likaGoogle, lokuphunyezwa kweOgg / Theora kwiYouTube.

Ukucamngca

Ukuba sifuna gcina iwebhu ivulekile, kufuneke si soloko ubheja kwiifomathi zasimahla evumela wonke umntu ukuba afumane ulwazi ngokukhululekileyo nangokukhululekileyo, ngaphandle kokubeka izithintelo endleleni kwaye ngaphezulu kwako konke ngaphandle kokunyanzela abadali bokuqulatha kunye nokubamba amasango ukuba ahlawule iilayisensi zamalungelo awodwa omenzi wechiza.

UGoogle anganakho ukuhlawula izigidi zeedola ngonyaka ukusebenzisa i-H.264 kwiYouTube okanye kwisikhangeli sayo seChannel, kwaye neMozilla inakho, kodwa umbandela wokuba izikhangeli zeMozilla zikhethe iifomathi zasimahla, ngenxa yoko bakumeleyo, kuba sisiseko se-intanethi kwaye ngenxa yokuba ikhowudi yesikhangeli kufuneka ikwazi ukusetyenziswa ngabantu besithathu ekungafuneki bahlawule iilayisensi kumntu wesithathu. Ngaba ucinga ukuba iFirefox ibinokuphuhliswa luluntu ukuba ngelaxesha bekufuneka ihlawule izigidi zeedola ukusebenzisa iitekhnoloji ezinje nge-HTML, CSS okanye iJavaScript?

Izikhangeli kunye neefowuni zomxholo kufuneka zibheje kwi-Ogg / Theora njenge-codec yethegi yevidiyo, kuba ibonelela ngezinto eziluncedo kuwo wonke umntu (ukongeza, yeyona iphunyezwe kwelona nani likhulu labakhangeli ngoku).

Masingavumeli i-web ukuba ihambele phambili ngokuxhomekeke kumalungelo awodwa omenzi wechiza athoba isantya kwinto entsha. Ewe simahla kwiifomathi, ewe kwiwebhu evulekileyo!

Ezinye izimvo kwihlabathi leMozilla:

• UMike Shaver -Ividiyo ye-HTML5 kunye neekhowudi
• URobert O'Callahan -Ividiyo, iNkululeko neMozilla
• UChristopher Blizzard -Ividiyo ye-HTML5 kunye ne-H.264

Kuthini nge? Ngaba ezikaGoogle zibonisa ilint? Ngaba le yeyona ndlela ilungileyo yokuqalisa ukutshabalalisa i-firefox kuba i-chrome, ethi nangona ilungile kakhulu, ingafikeleli kwizithende ze-firefox 3.6, ndingasathethi ke ngo-3.7?

Yithi h.264 ibhetele kune I-Ogg / iTheora, ngelixa kunokwenzeka ukuba liyinyani, ngaba sisizathu nje sokuba ungabhejeli kwibhola ethambileyo yasimahla? Ukuba uGoogle ubheja ngenene kwisoftware yasimahla, akufuneki ibele izixhobo zokuphucula I-Ogg / iTheora endaweni yokulahla?
