Wonke umntu uyamthiya uFlash. Ukuyisebenzisa, kuya kufuneka ufake iplagi-ngaphakathi, enzima ngokwayo. Kodwa ngokungathi ayonelanga, iphuma ngokukhawuleza, inemingxunya yokhuseleko, itya izixa ezikhulu zezixhobo, kwaye ayisebenzi kakuhle kwizixhobo ezininzi eziphathwayo. Ngale nto engqondweni, abantu bakwiGoogle kudala basebenza ukushenxisa i-YouTube ye-Adobe plug-in engasebenziyo ngoku. Ngelishwa, ethathe iminyaka eliqela, ekugqibeleni iyaphela: I-YouTube kutshanje ibhengeze ukuba izakusebenzisa i-HTML5 ngokungagqibekanga. Nangona kunjalo, oku kuya kuba kubasebenzisi bezona zikhangeli zangoku: Chrome, IE 11, Safari 8, kunye "neenguqulelo ze-beta zeFirefox".
Utshintsho lwalunzima kunokuba uninzi lukholelwa. Kwiminyaka nje emine edlulileyo, i-YouTube yenze uluhlu olude lweengxaki eyayinazo nge-HTML5. Namhlanje bacacisa ukuba bahambe njani ekusombululeni ingxaki nganye kunye nokuba zeziphi iitekhnoloji "ezifanayo" ekufuneka beziphuhlisile ukunika i-HTML5 ukonyusa okufunekayo.
Izandiso zeMediaSource
Ukusasazeka kwe-Bitrate ye-Adaptive (ABR) kubalulekile ekunikezeleni ngamava okujonga umgangatho, ukuvumela ukuba ukhawuleze ulungelelanise isisombululo kunye nokukhuphela isantya kwimeko yokutshintsha kweemeko zenethiwekhi. I-ABR inciphise ukubhuqa ngaphezulu kweepesenti ze-50 kwihlabathi liphela kwaye ukuya kuthi ga kwiipesenti ezingama-80 kwezona nethiwekhi zixineneyo. Izandiso zeMediaSource, okwangoku, vumela ukusasazwa bukhoma kwizikhombisi ezinje ngeXbox kunye nePS4, kwizixhobo ezinjengeChromecast, nakwizikhangeli zewebhu.
Ikhowudi yevidiyo yeVP9
I-HTML5 ivumela ukusetyenziswa kweVP9 (evulekileyo) ikhowudi yevidiyo-ephuhliswe nguGoogle- kwaye esebenza njengenye indlela yokufumana iikhowudi h264 y h265. Oku kwenza ukuba kudlalwe ividiyo ekumgangatho ophezulu ngokunciphisa i-bandwidth yeepesenti ezingama-35. Kwelinye icala, ukunciphisa ubungakanani beefayile zevidiyo kuvumela abantu abaninzi ngakumbi ukuba babe nokufikelela kwiividiyo ezikumgangatho we-HD nakwi-4K kwii-FPS ezingama-60; kwaye iividiyo ziya kuqala ngokukhawuleza nge-15-80 yepesenti. Ukongeza, i-YouTube sele igcina amakhulu ezigidi zevidiyo kwifomathi ye-VP9, ke ukuguquka kwazo akuyomfuneko.
I-DRM
Kwixesha elidlulileyo, ukhetho lweqonga lokuhambisa (iFlash, iSilverlight, njl. Ukongezwa kweendaba ngokufihliweyo ukwahlula umsebenzi wokukhusela umxholo ekuhanjisweni, ukuvumela ababoneleli bemixholo njengeYouTube ukuba basebenzise isidlali sevidiyo esinye se-HTML5 kuluhlu olubanzi lwamaqonga. Idityaniswe nokubethelwa okuqhelekileyo, iYouTube ixhasa itekhnoloji yokukhuselwa komxholo kumaqonga ahlukeneyo kunye neseti enye yeasethi, eyenza ukuba ukudlala kudlale ngokukhawuleza kwaye kube lula.
WebRTC
I-YouTube ivumela wonke umntu ukuba abelane ngevidiyo zakhe kwilizwe liphela, nokuba kungokufaka iividiyo esele zirekhodwe kwangaphambili okanye ngokungqamanisa ngqo. IWebRTC ikuvumela ukuba urekhode kwaye ulayishe iividiyo kwiYouTube usebenzisa itekhnoloji efanayo emva kweGoogle Hangouts.
Isikrini esigcwele
Ngokusebenzisa ii-API ezintsha ezikwisikrini esigcwele se-HTML5, iYouTube iyakwazi ukubonelela ngescreen esigcweleyo.
Inqaku kwi-DRM nakwi-HTML5
Olu phuculo aluzuzanga nje kuphela kuluntu lweYouTube, kodwa kushishino luphela. I-HTML5 yamkelwe ngabanye abanikezeli bokuqukethwe abanjengoNetflix kunye neVimeo, kunye neenkampani ezinje ngeMicrosoft kunye neApple, eyenye yezinto eziphambili kwimpumelelo yayo. Ngokubonelela ngeqonga elivulekileyo eliqhelekileyo, i-HTML5 ikwenzile ukuba kwenziwe iintlobo ezintsha zezixhobo, ezinje ngeChannelbook kunye neChromecast.
Ngoku, ngaphakathi kwale seti yeendaba ezimnandi, ukubandakanywa kwe-DRM akuyeki ukungqubana. Ngelishwa, ayisiyonto ngaphandle kwesiphelo esingenakuphepheka nesilindelweyo senoveli eyaqala phakathi ku-2013 xa ukufakwa kwe-DRM kwi-HTML5 kwamkelwa, emva koxinzelelo olukhulu oluvela kwezona zinkulu zikolu shishino, ezinje ngeGoogle, Apple, Microsoft, INetflix kunye neVimeo. Ke, ngoMeyi 2014, nkqu noMozilla kwafuneka anike ingalo yakhe ukuze ajike kwaye axhase DRM kwiFirefox. Kwiqela elizinikeleyo kwisoftware yasimahla kunye nemigangatho evulekileyo, esi yayisisigqibo esinzima. I-DRM isetyenziselwa ukuthintela ukufikelela ngokukuko kwimathiriyeli enamalungelo obunini kwaye isebenzisa iimodyuli zemithombo evaliweyo, zombini eziya kuhamba ngokuchasene nefilosofi yeMozilla kunye ne-HTML5: umgangatho ovulekileyo wewebhu.
Ngaphandle koko, akukho mathandabuzo ukuba i-HTML5, nokuba ilitye elikwisihlangu lokubandakanya i-DRM, lingcono kuneFlash. Ngaphandle kothandabuza. Ukusetyenziswa okungagqibekanga kwe-HTML5 kwiYouTube, eyona portal yevidiyo inkulu phaya, ziindaba ezimnandi. Inokuthelekiswa kuphela ne Ukusetyenziswa kwe-HTML5 ngeNetflix. Ngapha koko, enye yekalika kunye nesanti.
I-YouTube yamkela i-HTML5 ngokuzenzekelayo. Nangona kunjalo, oku kuya kuba kubasebenzisi bezona zikhangeli zangoku: Chrome, IE 11, Safari 8, kunye "neenguqulelo ze-beta zeFirefox"?
Oko kuthetha ukuba uhlobo ngalunye "oluzinzileyo" lweFirefox, ... NGEKE ube ne-HTML5 kuYouTube ngokungagqibekanga? KwiLinux Mint, iFlash Player ifakwe ngokungagqibekanga, kwaye isebenza ngokugqibeleleyo ngeFirefox kwiYouTube, andiyiboni kufuneka ufake "plug-in".
I-HTML5 kunye neGnash, iseluhlaza!
Batsho okufanayo ngeWebRTC, kwaye ngoku iFirefox sele ixhasa obu buchwephesha ngokuqhelekileyo. Inkxaso yeevidiyo ze-HTML5 ayinxalenye, kuba nangona iFirefox ixhasa iividiyo zeVP9, ayiziboni xa idlala ividiyo yeYouTube kwiHTML5. Yiyo loo nto, nomdlali we-HTML5 we-YouTube eseluhlaza kwi-injini yokunikezela nge-Gecko.
Ukuba ungathandabuzeki ukuba ezi ziindaba ezilungileyo. Inqaku elilungileyo!
Sala kakuhle. Inqaku elilungileyo!
Ngokubhekisele kwiFirefox, kunokuthiwa umdlali we-HTML5 ubuncinci uphuculiwe kwaye usebenza ngendlela efanayo neChannel kunye neOpera Blink. Umdlali unokuba sele eqhuba ngokungagqibekanga enkosi kwi-VP9 codec (kwiChromium, engenayo i-H.265 / H.264 kunye ne-MPEG-4 codecs, ukudlala ngokufanelekileyo).
Kwiinguqulelo zamva nje zeFirefox iplagi yeH.264 sele ifakiwe.
Kwi-Iceweasel kufuneka ufake i-GStreamer ukuze usebenzise i-H.264 codec.
Ngexesha elithile elidlulileyo ndakhumbula ukuba ndizamile ividiyo ene-html5 kwaye ngelo xesha yayisisikizi kodwa ngoku yonke into ipholile kwaye awuluboni notshintsho.
Ukuba ii-xvideos kunye ne-youporn ziyamkele ukuba ihambele kwiiselfowuni, i-youtube yayisele ihambile.
Ndiyakholelwa ukuba ividiyo ye-XXX portal, xa ibonisa uguqulelo olungafakwanga u-pr0n olufutshane olwenziwe ngeGoogle Glass, lwalusebenzisa umdlali we-HTML5. Kwaye uVimeo, unjani loo nto zukulent, Wayephambi kweXfideos nabanye.
Ndingabuka kuphela kwi-360p kunye ne-240p
Kuya kufuneka unento engalunganga kuba iyandisebenzela kuzo zonke izikhangeli endizizamile.
Andiboni iividiyo ezikumgangatho we-144p 240p 480p 1080p kwi-HTML5 ene-firefox kuphela i-360p kunye ne-720p, ngaba ukhona umntu owaziyo ukuba kutheni kusenzeka oko?
Ngemigangatho exhaswa yi-Gecko enikezela ngenjini, esebenzisa kuphela ezo ziqinisekiswe yi-W3C kuhlobo oluzinzileyo lweFirefox. Ngenjini yokunikezela ngeBlink- esetyenziswa nguMaxthon, uGoogle Chrome / uChromium, uOpera (uguqulelo lwangoku) kunye ne-SWare Iron- ixhasa imigangatho engaphezulu, kodwa ayikabikho (okanye ikwinkqubo yokuba) ixhaswe yi W3C.
Kwaye ngokungathi ayonelanga, oku kukwaphembelela umgangatho webhanwidth anayo.
ziindaba ezimnandi ezidanyazayo ziyothusa ngakumbi xa zifumana inkxaso kunikezelo lwe-gnu / linux
