WebM kuya AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani umsindo kusuka kuhele lami WebM njenge AMR?

Layisha phezulu ihele WebM futhi umguquli ukhipha umsindo, bese uguqula ikhodi liyi AMR. Akukho sikhathi sevidiyo sesibili - umsindo obonakalayo ususwa ngokushesha ngakho-ke ukukhishwa kusheshe kakhulu kunalokho okuphelele kokuphinde uguqule ikhodi. I-WebM iyingxenye eqinile ye-Matroska eshicilelwe yi-Google ngo-2010 ekhethekile ekubeni yividiyo ye-HTML5 equkethwe ngaphandle kwe-royalty. I-AMR iyi-Adaptive Multi-Rate, i-codec yokukhuluma i-3GPP ejwayelekile yezingcingo zokukhuluma ze-GSM nezinhlelo zokurekhoda amagama ezimoto.

Ingabe ukushintsha WebM kuya ku AMR kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-AMR encoder isebenza kusuka kumsindo osele udlulele engxenyeni eyodwa ye-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, uku-encoding i-AMR kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele. WebM idinga ukucophelela: VP8 noma VP9 ividiyo (AV1 manje) nge Vorbis noma Opus umsindo, futhi akukho okuthile okuningi. I-AMR iyi-narrowband speech codec esebenza phakathi kuka-4.75 no-12.2 kbps, emodela i-human vocal tract endaweni yobubanzi obugcwele be-audio spectrum.

Kungani umculo uzwakala ubuhlungu kulo mguquko?

Ngenxa yokuthi ingxenye eyodwa iyi-codec yokuxoxa hhayi i-codec yomculo. Imodelisa i-human vocal tract futhi isusa konke okungaphandle kwe-bandwidth yefoni, okulungile ku-voice memo futhi kulahlekile kunoma yini enezithuluzi ngaphakathi. Ukushintshana eduze kwayo akukwazi ukubuyisela izifremu ezilahlekile — azikhombisile endaweni yokuqala. WebM ilungile encane noma kuphi ngaphandle kwe-browser - ama-video editors, amafoni 'ama-galleries asekhaya nama-Smart TVs ahlala engaziboni.

Yini i-bitrate yomsindo osetshenziswa yi-AMR ekhishwayo?

I-lossy AMR ikhodwe ku-192 kbps ngokuzenzakalela. Uhlelo lwekhwalithi yomsindo lunikeza futhi 320 kbps ukuqinisekisa ukhwalithi enhle kanye ne-128 kbps ukuqinisekisa ifayela elincane. I-lossless AMR (WAV, FLAC) i ignore i-bitrate futhi igcine yonke isampula.

Ingabe ngizolahlekelwa ubunjani besandi uma ngisuka ku WebM kuya ku AMR?

Uma AMR ingekho lutho (WAV, FLAC), yonke isampula igcinwa ngokugcwele. Uma AMR ingekho lutho (MP3, AAC, OGG, Opus), i-AMR codec icindezela kabusha umsuka womsindo — ku-192 kbps imiphumela icacile cishe kuzo zonke izithako. Ukuya kwe-nothing → akukho lutho akugcini nje ngokubuyisela imininingwane ekhishwe.

Ingabe ngizokhipha umsindo kusuka ku WebM amafayela amaningi kuya ku AMR ngeqembu elilodwa?

Amafayela amaningi emisebenzini eyodwa adinga iphrojekthi ekhokhelwa. Ukusetshenziswa okumahhala kuyisifayela esisodwa ngasinye sokuguqulwa, ukuguqulwa okufanayo ngehora. Kuphrojekthi ekhokhelwa ungangeza amafayela amaningi kumsebenzi owodwa, bese ulanda impendulo ngayinye yayo noma zonke ku-ZIP eyodwa.

Ingabe kuthatha isikhathi esingakanani ukukhishwa kwe AMR umsindo kusuka ku-WebM wehora elilodwa?

Kuxhomekeka kubukhulu nesikhathi sohele. Amadokhumende amancane namasithombe avame ukulungiselelwa ngokushesha. Amavidiyo ade athatha isikhathi eside, ngoba amavidiyo aguqulwa aphinde akhode ifreyimu ngayinye.

Ingabe ngizokhipha kuphela isigaba se WebM somsindo njenge AMR?

Akunalesi sisetshenziswa ngokuqondile — khipha umsindo wonke njenge AMR, bese usebenzisa /audio-trim/ noma /audio-cutter/ ukucisha inqwaba. Indlela yezinhlangothi ezimbili ivame ukuba isheshe kunalokho okwenziwayo futhi ikunikeza ukulawula okucacile kwe-waveform-level.

Ingabe ihele lami WebM liyimfihlo ngesikhathi sokukhipha umsindo?

Yebo. Amafayela WebM alayishwe phezulu aphathwa kumaseva ethu okuguqula, akukho muntu obhekana nawo, futhi angeke ahlukaniswe. Ukulayishwa kanye nokuguqulwa kwe AMR kususwa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa, okushiya isikhathi sokulanda imiphumela. Bona /privacy/ ukufinyelela kunqubomgomo egcwele.

Kungani ihele AMR linezingcindezi ezingenalutho lapho i WebM ikhona umsindo?

Ngokuvamile i-WebM ithatha ngaphezu kwe-track yomsindo eyodwa futhi enye eyaguqulwa ihlala ihlala ikhululekile noma iyisithathu. Umguquli ukhetha i-track yomsindo eyodwa ngokuzenzakalela, ngokuvamile i-one enkulu, futhi lekhasi alinazo izilungiselelo zokukhetha i-track eyahlukileyo. Uma i-one engekho iphuma, shintsha i-WebM nge-track oyifunayo kuqala (i-VLC noma i-ffmpeg ingakwenza lokhu) bese uyiguqula futhi.

WebM

I-WebM yenzelwe iwebhu, inikeza ukusakaza ividiyo ngaphandle kwemali yokukhokha ngama-codec e-VP8/VP9.

AMR

I-AMR (I-Adaptive Multi-Rate) ifomethi yokuminyanisa yomsindo elungiselelwe ukubhalwa kwekhodi yenkulumo. Ivamise ukusetshenziswa kumakhalekhukhwini ukuqoshwa kwezwi nokudlalwa komsindo.
