MP4 ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-audio kwi-MP4 njenge-AMR?

Layisha phezulu ifayili ye-MP4 kwaye umguquli ukhuphe umculo wesandi, emva koko uphinde uyikhode njenge-AMR. Akukho kuphinda kukhodwe ividiyo kwenziwa — kuqhubekeka kuphela umculo osuka kwividiyo, ogcina ikhawuleze nakwividiyo ende.

Ingaba ubunjani besandi bufana nengoma yokuqala ye MP4?

Ewe - isandi sikhutshwa kwi-bitrate yombhalo ovela kumbhalo ovela kumbhalo apho kunokwenzeka khona. Ukuba ukhetha i-AMR bitrate ephakamileyo kune-source, ifayile ayizukuphucula ubunjani, ikhule kuphela ngobungakanani.

Ingaba ukuguqulwa kwe-MP4 ukuya kwi-AMR kunokuphinda kuphindeke?

Ungaguqula i-AMR kwakhona kwi-MP4 kule ndawo. Ukuba nayiphi na ifomati ebandakanyiweyo ilahlekile, i-round-trip ayizukuba yi-bit-perfect nakuba ibonakalayo okanye icacile.

Yintoni umgangatho wemveliso endingalindele ukuba ndiyilindele ukusuka kwi-MP4 ukuya kwi-AMR?

Izicwangciso ezimiselweyo zijolise kwi-broadcast / umgangatho we-web - ngokubonakalayo ifana nomcebo kubabukeli abaninzi. Ukusetyenziswa kovimba, khetha ukhetho oluphezulu lomgangatho kwimimiselo yoguquli.

Ingaba ukutshintsha MP4 ukuya AMR kukwindawo yesibini yokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AMR encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu impumelelo ihlala icacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i AMR ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-MP4 eninzi eluhlaza yi-H.264 yevidiyo enesandi se-AAC; isiqulathi sigcina ngokusemthethweni i-HEVC, i-AV1 ne-VP9. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, eyenza imodeli yomsebenzi wokuthetha womntu kunokuba isebenze kwi-audio epheleleyo.

Ithini into ebangela ukuba i-audio ekwi-multichannel iguqulwe kwi MP4 ukuya kwi AMR?

Ijika ezantsi kwi-stereo, kuba AMR ayinayo indlela esebenzayo ye-multichannel. Ukhuphelo lwe-downmix lusebenzisa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-mandla zixutywe kwinqanaba eliphantsi. Nantoni na exhomekeke kubekwa kwesiqhagamshelanisi esikhethekileyo siphelile xa oko kwenzeka. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okungaphezulu kweefrequencies zefowuni, kwaye akukho xabiso lokucofa kwakhona liyibuyisela.

Kutheni umculo uthetha ntoni xa uguqulwa?

Kuba enye icala liyi codec yokuthetha kune codec yengoma. Imodelisa umjelo wokuthetha womntu kwaye ishiya konke ngaphandle kwe bandwidth yefowuni, elungileyo kwimemo yokuthetha neyophazamisayo nantoni na enezixhobo kuyo. Ukutshintsha kude nayo akuyi kubuyisela uxinzelelo olulahlekileyo - akufuneki kubekho ukuvulwa kwindawo yokuqala. I-MP4 ixhasa kuphela ifomati enye ethandwayo yesihloko esingaphantsi (mov_text), kwaye i-multi-track audio ayithembeki ngaphandle kwee-desktop players.

Ingaba kukho umda wobungakanani befayili xa uguqula i-MP4 ibe yi-AMR?

Ulayisho phezulu olungaziwayo luphelelwe lixesha ngokumiselweyo; i-akhawunti ebhalisiweyo ekhululekileyo ifumana umda ophezulu, kwaye i-akhawunti ye-Pro ayinalo umda wefayili nganye. Inkumbulo yesikhangeli sihlala siyimfuneko yothintelo ixesha elide phambi kokuba umda wethu we-server-side uqale.

Ndingaguqula iifayili ezininzi ze-MP4 zibe yi-AMR ngaxeshanye?

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze MP4 kwifayili enye yokulayisha - umguquli uqhubekeka nazo ngokuthe tye kwaye ubuyisele i-ZIP yeziphumo ze AMR. Akukho mfuneko yokuphinda uqhubekeke inkqubo yefayili nganye.

Ithini into eyenza ukuba i-MP4 yam ifile iguqulwe?

Iifayili ezilayishwe phezulu kunye ne-AMR iimveliso zicinywa ngokuzenzekelayo emva kwefestile efutshane yokugcina. Asiyi kujonga, sizonwabele, okanye siqeqeshe kwiifayili zomsebenzisi. Ikhonkco lokulayisha ezantsi ngokuthe ngqo limiselwe ixesha kwaye lidityaniswe kwintlanganiso yakho.

Ziziphi iinkqubo ezikwaziyo ukudlala ifayili ye AMR?

AMR idlala kumaqela amaninzi emidlalo, kwii-browser, kunye neelayibrari zemidiya. I-iTunes / i-Apple Music, i-VLC, i-Foobar2000, kunye neenkqubo zemidiya yefowuni ziphatha ngokuzimeleyo.

Ingaba ndifuna ukufaka inkqubo yokusebenza ukutshintsha i-MP4 ibe yi-AMR?

Hayi. Umguquli uqhuba ngokupheleleyo kwi-browser yakho kunye ne-cloud yethu - akukho plug-in, akukho kufakwa, akukho malungelo omphathi. Isebenza kwiWindows, macOS, Linux, ChromeOS, iOS, kunye ne-Android.
