Indlela yokuguqula AMR ukuba WebM

Inyathelo 1: Layisha eyakho AMR iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho WebM iifayile

AMR ukuba WebM Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani ifayili AMR ibe yi WebM?

Layisha phezulu ifayili yakho AMR usebenzisa umkhethi ophezulu kwaye umguquli ufumanisa uhlobo lombhalo ovela kum kwaye uqhube i AMR -> WebM ipayipi. Isiphumo sikhuphela ngokuzenzekelayo xa uguqulo lugqityiwe; akukho akhawunti ifunekayo kuguqulelo oluthile. I-AMR yi-Adaptive Multi-Rate, i-codec yokuthetha ye-3GPP emiselwe kwi-GSM yezingxoxo zelizwi kunye nezixhobo zokurekhoda ilizwi elihambayo. I-WebM yinxalenye encinci eqinileyo ye-Matroska epapashwe yiGoogle ngo-2010 ekhethekileyo ukunika i-HTML5 ividiyo isiqulathi seefayili esingenazo iirhafu.

Umfanekiso uya kuba yintoni ukuba ndibeka i-AMR yesandi kwi-WebM ifayili?

Ukhetha oku, kuba isandi kuphela asikho umfanekiso. Okungagqibekanga kukubonisa i-waveform eqinileyo, kwaye unganikezela umfanekiso oqinileyo endaweni yoko - ubugcisa besiqhoboshelo, ikhadi lesihloko, umfanekiso - ogcinwa ixesha elipheleleyo. Oku kwenza ifayile ilayishwe phezulu kwividiyo kuphela i platforms ezingenakuxhasa umkhondo wesandi omnyama. I-WebM idlala ngokusemthethweni kwi-browser nganye ekhoyo ngoku ngaphandle kokufaka, ngaphandle kwelayisensi yemali, ngaphandle kokubonisa ipateni, eyenza ukuba imiselwe kwividiyo efakwe kwi-web.

Ingaba i WebM iyakuba mkhulu kangakanani na xa ithelekiswa ne AMR?

Incinci kakhulu, ukuba usebenzisa umfanekiso omiselweyo ongatshintshiyo. Isakhelo esithe nkqo sicinezela ukuba akukho nto ingaphezulu kokuqhubeka kwayo yonke kuba isakhelo ngasinye sifana neso siphelileyo, ngoko ke ifayile ilawulwa ngumculo wesandi. Ukukhetha i-waveform ephefumlayo endaweni yoko idibanisa i-video data eyiyo kwaye ingaphindaphindwa okanye iphindwe kabini i-result.

Ingaba i WebM iya kuvula ngokuthe ngqo kwi-browser?

Ewe, kwaye AMR ayizukuba nayo. Iibrawuzi zithumela ikhowudi yokufikelela kwi WebM kwaye akukho nto kwi AMR, ngoko AMR ikhonkco libangela ulayisho ezantsi ngelixa i WebM ibonisa umgca. Oku kuqhelekileyo kubangela ukhetho xa ifayile isiya kwiphepha le web kunokuba ifike kwisicelo.

Ingaba i-AMR ukuya kwi-WebM ikhululekile?

Ewe - uguqulelo olusisiseko AMR -> WebM lukhululekile ngaphandle kobhaliso. I-Premium idibanisa umda ophezulu wobungakanani befayili nganye, abasebenzi abangaphezulu beqela elifanayo, kwaye isusa ii-ad.

Ingaba i AMR ifile ikhulu kangakanani na ndiyiguqule ibe yi WebM?

Ii-akhawunti ezikhululekileyo: ukuya kuthi ga kwi-100 MB ngefayili nganye ye AMR. I-Premium: ihlala i-1 GB ngefayili nganye, kuxhomekeke kuhlobo lombhalo we AMR. Iifayili ezinkulu kakhulu zihlukaniswa zibe zii-chunks kwi-server-side xa i-WebM ivumela.

Ingaba uguqulelo lutshintsha okuqulethwe kwi AMR yam?

Uguqulelo lugcina yonke into ekhoyo kwi-informati enokuthi imele i-AMR ne-WebM. Iimpawu ze-WebM forma ayikwazi ukugcina (i-vector data kwi-raster output, iifomu kwi-plain-text output, iifonti ezifakelweyo kwi-image output) zi-rasterized okanye zi-stripped — iphepha leziphumo libonisa nayiphi na i-feature loss ngokucacileyo. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, imodelisa umjelo wokuthetha womntu kunokuba iqulethe i-audio spectrum. I-WebM imiselwe ukuba incinci: i-VP8 okanye i-VP9 ividiyo (i-AV1 ngoku isasazeka) ene-Vorbis okanye i-Opus isandi, akukho nto enye.

Ndingaguqula iifayile ezininzi AMR zibe WebM ngaxeshanye?

Ewe — susa iifayile ezininzi AMR kummandla wokulayisha kwaye zifolole ngokuthe tye. I-Premium inemisebenzi emininzi ethe tye; kwi-50-file batch le yi-difference phakathi kwemizuzu nemizuzu.

Ingaba i-AMR ukuya kwi-WebM iguqula isebenze kwifowuni / i-tablet?

Ewe - i-UI iphendula kwaye inkqubo yokuguqula iqhuba kwicala leseva, ngoko ii-mobile devices zikhuphela-za-zikhuphele njenge-desktops. I-iOS kunye ne-Android browser files pickers (ikhamera ijikeleza, i-Files app) isebenza ekupheleni-kwi-kuphela ngaphandle kwe-app.

Zithini iiseva ezixhaswa ngu AMR ukuya ku WebM umguquli?

I-Chrome, i-Firefox, i-Safari (15+), i-Edge, ne-Opera. Umguquli usebenzisa `<input type="file">` oqhelekileyo wokulayisha — akukho WebAssembly okanye i-PWA ixhomekeke — ngoko ke nakwi-browser edala iguqula AMR ibe yi WebM ngokuphumelelayo.

Ingaba ii-AMR zam iifayile zigcinwa ngokufihlakeleyo?

Ewe — iifayile ezilayishwe phezulu AMR ziqhubekekiswa kubasebenzi ababekwe ngokuzimeleyo kwaye zicinywe kwimizuzu. Asizukuzijonga, sizigcine, okanye sizinikezele imixholo. Bona /privacy/ kwifestile yokugcina i-data. I-AMR isenza ukuba urekhodo lwesandi lube luncinci kakhulu - iyure enye yokuthetha ilungele ii-megabytes ezimbalwa - kwaye yiyo loo nto ifowuni ezininzi zihlala zirekhoda kuyo uqhagamshelwano.

Yintoni ukuba u-WebM ulayishe aqalile ngokuzenzekelayo?

Sukwenza nasiphi na isithinteli se-pop-up, emva koko nqakraza iqhosha lokulayisha ezantsi ngesandla. Inxulumano yeziphumo ihlala isebenza iiyure ezingama-24, ngoko ukuba uthungelwano lwakho aluphumelelanga phakathi kokulayisha ezantsi ungaphinda uqalise ukusuka kwiphepha leziphumo ngaphandle kokuphinda ulayishe i-AMR.

AMR

I-AMR (I-Adaptive Multi-Rate) yifomathi yocinezelo lwe-audio elungiselelwe ikhowudi yentetho. Iqhele ukusetyenziswa kwiifowuni eziphathwayo ukwenzela ukurekhoda kwelizwi kunye nokudlala kwakhona.
