Kwiintsuku ezimbalwa ezidlulileyo Abaphuhlisi bakaGoogle bakhutshiwe ngeposi blog abayithathileyo Isigqibo sokwenza umthombo ovulekileyo weLyra. ILyra isekwe ekufundeni komatshini ukwenza ukuba umnxeba ophakamileyo wezwi kwiimeko eziphantsi zebhendi.
Ngayo le nto izibonelelo kwaye ivumela abanye abaphuhlisi ukuba bondle izicelo zabo unxibelelwano kunye nokuphuhlisa uLyra kwiindlela ezintsha.
Isiseko sokusetyenziswa kwemithombo yeendaba kumashumi eminyaka, iikhowudi zenze ukuba izicelo ezinobubanzi bebhendi zidlulise idatha ngokufanelekileyo.
Njenge, Ukuphuculwa kwekhowudi, kwividiyo nakwividiyo, kubonisa umceli mngeni oqhubekayo-Nika umgangatho ophakamileyo, sebenzisa idatha encinci, kunye nokunciphisa ukubambezeleka konxibelelwano lwexesha langempela.
Nangona ividiyo inokubonakala ngathi idla i-bandwidth engaphezulu kuneaudiyo, ii-codecs zevidiyo zangoku zinokufikelela kumaxabiso asezantsi kunezinye zeekhowudi zentetho ezikumgangatho ophezulu ezisetyenziswayo namhlanje.
Umdibaniso we Izinga eliphantsi lezwi kunye nevidiyo yekhowudi inokuzisa amava akumgangatho ophezulu wokubiza ividiyo Nokuba kuthungelwano lwebhendi ephantsi. Nangona kunjalo, ngokwembali, isantya esisezantsi senqanaba lekhowudi yeaudiyo, isandi esingaqondakali kakuhle kwisandi kunye neerobhothi ngakumbi.
Kananjalo, ngelixa abanye abantu benofikelelo kuthungelwano oluphezulu lomgangatho webroadband, eli nqanaba lokudityaniswa alikho kwindalo iphela, kwaye nabantu abahlala kwiindawo ezixhumeke kakuhle ngamanye amaxesha bajongana nokunxibelelana kwenethiwekhi okungalunganga, uqhagamshelo lwenethiwekhi olungalunganga, kunye nonxibelelwano.
Ukusombulula le ngxaki, UGoogle udale uLyra, umgangatho ophezulu, ikhowudi yokuthetha enexabiso eliphantsi eyenza unxibelelwano ngelizwi lufumaneke nakwezona nethiwekhi zicothayo.
Ukwenza oku, UGoogle usebenzise ubuchule bokwenza iikhowudi ngokwesiko ngelixa esebenzisa inkqubela phambili ekufundeni komatshini ngeemodeli eziqeqeshwe ngaphezulu kwewaka leedatha zedatha ukwenza indlela entsha yoxinzelelo kunye nokuhambisa imiqondiso yelizwi.
Ikhowudi kaLyra ibhaliwe kwi-C ++ ngesantya, ukusebenza kunye nokusebenzisana, kunye nokusebenzisa isakhelo seBazel kunye ne-Abseil kunye nesakhelo seGoogleTest kuvavanyo olupheleleyo lweyunithi.
I-API eSisiseko ibonelela ujongano lokufaka ikhowudi kunye nokususa ikhowudi kwipakethi nakwinqanaba lefayile. Isixhobo esigqibeleleyo sokwenza imiqondiso sibonelelwe kwaye kubandakanya iifilitha ezahlukeneyo kunye notshintsho.
“Isampulu yesicelo sethu sidibanisa ne-Android NDK ukubonisa indlela yokuhlanganisa ikhowudi yemveli kaLyra kwisicelo esisekwe kwiJava Android. Sikwabonelela ngobunzima bevektha kunye nezinto zokulinganisa ezifunekayo ukuqhuba uLyra, ”utshilo uGoogle. Olu khululo lubonelela ngezixhobo eziyimfuneko kubaphuhlisi bokukhowuda kunye nokumisela iaudio ngeLyra, eyenzelwe iqonga le-Android le-ARM engama-64, kunye nohlobo lweLinux.
Iimpawu zichongiwe kwifom yamaza kusetyenziswa imodeli yokuvelisa. Iimodeli zokuvelisa ziluhlobo olukhethekileyo lweemodeli zokufunda ngomatshini ezilungele ukuphinda zenze ifomathi yomsindo ogqityiweyo ukusuka kwinani eliqingqiweyo lemisebenzi.
Uyilo lukaLyra lufana kakhulu neekhowudi zomsindo zemveli, Ezingumqolo kunxibelelwano lwe-Intanethi kumashumi eminyaka. Ngelixa ezi codec zemveli zisekwe kubuchwephesha bokulungiswa kwemiqondiso yedijithali, uLyra uhlala kwimodeli yokuvelisa amandla okwakha kwakhona umqondiso wentetho ekumgangatho ophezulu.
UGoogle uphumeze uLyra kwividiyo yasimahla yokubiza i-Duo kwaye wathi yenza ikhowudi ukuba ibe ngumthombo ovulekileyo kuba ucinga ukuba inokuba ilungele ezinye iinkonzo.
UGoogle ukholelwa ukuba kukho uninzi lweapps ezinokuthi zilungele uLyra, nokuba yeyokugcina isixa esikhulu selizwi, ukugcina ubomi bebhetri, okanye ukunciphisa ukuxinana kwenethiwekhi kwiimeko ezixakekileyo.
"Sijonge phambili ekuboneni ubuchule obubonisa imithombo yoluntu evulekileyo esetyenziswe eLyra ukuhambisa izicelo ezinamandla nezizodwa," utshilo uGoogle.
