MPG kuya FLV Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani i-MPG ibe yi-FLV ngaphandle kokubuyisela umbhalo ongezansi wevidiyo?

Uma ama-MPG ne-FLV amabhokisi angaba nesixhumi esifanayo (H.264, H.265, VP9, AV1), umguquli ubuyela emuva ku-remux: ama-streams aphansi akopiwe ngo-byte-by-byte ku-FLV ibhokisi futhi ushintsho lwe-wrapper kuphela. I-remux ye-1 GB MPG ku-FLV ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. Okuqukethwe yi-MPEG-1 noma i-MPEG-2 video ne-MP2 umsindo; ukuxhuma kanye nesakhiwo se-GOP kufana nehele le-.mpeg. I-FLV ivame ukuphatha i-Sorrenson Spark noma i-H.264 video ne-MP3 noma i-AAC audio, efakwe kufomethi yokuhamba eyenziwe nge-RTMP delivery.

I-MPG yami ibonisa ama-comb lines ekuhambeni - ngabe lokhu kuzodluliselwa ku-FLV?

Kuzokwenzeka uma ungasebenzisi i-deinterlace, futhi MPG okuqukethwe kuvame ukuxhunywa ngoba ifomu livela esikhathi sokusabalalisa ne-DVD. Amafreyimu axhunywe agcina ama-fields amabili aphakathi nendawo aphezulu athathwe ngengxenye yesihlanu yesibili; kufoni noma kumboniso oqhubekayo-oqhubekayo ofunda njenge-horizontal combing nganoma yini ehambayo. Vula ukhetho lokuxhunyaniswa futhi umbhalo-mqoka uxhuma ama-fields kuwo wonke ama-frames aqhubekayo ngaphambi kokubhala i-FLV. MPG iyi-MPEG i-program stream efanayo ne-.mpeg — isibonisi sokubhala esithathu siyi-DOS-era truncation, hhayi i-format ehlukile.

I MPG yami inezinhlamvu zomsindo eziningi — zingaba zonke zihlala ngaphakathi kwe FLV?

Akunakuthembeka. MPG igcina imisindo eminingi njengezingoma zohlobo lokuqala, kodwa FLV uxhaso lokudlala ngaphezu kwengoma yokuqala akulingani, ngakho abadlali abaningi bazoveza kuphela eyodwa. Khetha ingoma oyifunayo ngaphambi kokuguqula; abanye bakhishwa kahle kumafayela abo ngaphezu kokushiya emgodini ofihlayo. MPG yisibonisi sesoftware ye-DVD, ama-camcorders adala kanye nezixhobo zokusakaza ziyazi, ngakho ihlala isetshenziswa ezipayipini. Akukho isiphequluli, ifoni noma i-TV ekhona engakwazi ukudlala i-FLV — noma yini ekhona kule bhokisi kumele ihunyushwe ngaphandle ukuze ihlale ibonakale.

Ingabe i-FLV izodlala ngokulula ku-smartphone noma ku-TV?

Kungenzeka ukuthi ayisebenzi. MPG i-decoded yi-silicon ekhethekile kumafoni, ama-tablets nama-TV, ngakho-ke idlala ngaphandle kokucindezela ibhethri. FLV ngokuvamile ibuyela emuva ku-software decoding ku-hardware efanayo - u-CPU ophezulu, isisetshenziswa esipholile, namafreyimu akhuphuka ku-4K material. Uhlelo oluzosetshenziswa, MPG luyi-container ephephile yokuhlala kuyo.

Yini ekwenzeke ku-5.1 surround audio uma uguqula MPG ku-FLV?

Kuxutshwe phansi ku-stereo, ngoba FLV ayikho indlela ethembekile ye-multichannel. Ukuvala ngezansi kusetshenziswa izilinganiso ezijwayelekile ze-ITU ukuze ukuxhumana engxenyeni ye-channel ihlale icacile futhi izimo zifike ezingeni eliphansi kune-elingafihli. Noma yini esekelwe ekubekeni kwe-channel ehlukile idlule ngemuva kwalokho.

Ingabe kukhona okushintshayo phakathi kwefomethi ezimbili ezidalayo njenge MPG ne FLV?

Uma nje ingxenye ekhethekile yemishini idinga isiphetho. Ifomethi zombili zivela kusikhathi esifanayo se-H.264, ngakho noma yikuphi ukushintshana kuthengiswa ukusebenza kahle, ukhwalithi noma ubufakazi bokuphila - kuthengiswa ukuhambisana nedivayisi eyodwa ekhethekile. Uma inhloso ukugcina isithombe esisetshenziswayo isikhathi eside, ukuguqula kwibhokisi elikhona endaweni ye-sideways. MPG ithola wonke ama MPEG-2 amaphutha - i-bitrate enzima, ukuxhuma, akukho ngezansi okuthambile - kanye nokungqubuzana kwezinhlamvu ezimbili ezibanzi zefomethi eyodwa.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa MPG kuya ku FLV?

Yebo — wonke umculo ohambayo ku MPG (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku FLV lapho isiqoqi esizosiza umsindo ohambayo oningi. MKV ne MOV ziphatha umculo ohambayo ongenasiphelo; MP4 isekela abaningi kodwa abanye abadlali behardware babona umculo 1 kuphela; WebM iphele ku-Opus / Vorbis umculo owodwa. FLV yi-Flash Video container ephethe yonke i-web video kusukela ngo-2003 kuze kube yilapho i-Flash ikhubazekile ekugcineni kuka-2020.

Ingabe amabhayisikobho esihloko esingezansi agcinwa uma kuguqulwa MPG kuya ku FLV?

Izihloko ezincane ezilula (izihloko ezikhethiwe) zihlala lapho FLV zingazithwala: MKV igcina i-SRT, ASS, SSA, PGS, VobSub ngokusemthethweni; MP4 igcina kuphela i-mov_text (ifomethi ephukile). Ukushintsha MKV nge-ASS styled subs ku-MP4 kuzozikhuphula zibe yi-mov_text noma zizicwebezele. Izihloko ezinzima (zicwebezelelwe kwividiyo) zithwale ngaphandle kokungabaza.

Ingabe MPG kuya ku FLV igcina iziphawuli zesiga-nyezi / ukuzula kwe-DVD-style?

Isigaba se-metadata sidlulisa phakathi kuka MPG no FLV lapho izihlungi zombili zixhasa isiqephu se-atomi (MKV, MP4, MOV). I-WebM igcina iziqephu kwi-Matroska-compatible block, ngakho-ke i-MKV <-> isigaba se-WebM sihamba ngokuhlanzekile. I-AVI ayinasiqephu esicacisiwe, ngakho-ke ukushintsha i-AVI ibe yi-FLV kwenza ifayela elingahlukanisiwe ngaphandle kokuthi uhlanganise iziphawuli ngesandla.

Yini mayelana nezifakiwe ze-MKV (izifomethi, isigqoko somsebenzi) uma usuka ku MPG usuka ku FLV?

MKV yindawo yokugcina eyinhloko kuphela egcina amafayela axhunywe ngokuzenzakalela (izifomethi ze-TTF ze-ASS subs, isithombe sokuzivikela se-JPG, izingeniso ze-PDF eziguqulwe nge-fan). Ukusuka ku-MPG kuya ku-FLV ushiya lezi zifomethi lapho i-FLV ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-MPG njenge-backup uma uhlala ubheke izifomethi ezixhunywe.

Yini i-codec esetshenziswa yi-FLV ngokuzenzakalela?

I-codec ejwayelekile ikhethiwe ukufana ne FLV isitoreji ngokuzithandela: MKV ikhetha i-H.265 (HEVC) ukucindezela okuhle; MP4 ikhetha i-H.264 ukuxhasa isisetshenziswa esibanzi; WebM ikhetha i-VP9; AVI isebenzisa i-MPEG-4 ASP (DivX/Xvid lineage). Nciphisa nge-codec ethuthukisiwe engezansi — AV1 itholakala ku-MKV / WebM lapho ufuna khona ukucindezela okuphezulu futhi ungalindela ukucindezela. FLV's low per-packet overhead yenze it okungcono e streaming phezu ukuxhumana unreliable yesikhathi sayo, futhi amafayela amakhulu yayo akhona.

Ingabe i-HDR (HDR10, Dolby Vision) ihlala isikhathi eside MPG kuya ku-FLV?

I-HDR metadata ehlala njalo (i-HDR10 mastering display values, max content light level) ihamba phambili ku-FLV uma izihlungi zombili ne-codec ekhethiwe ziyixhasa (HEVC, AV1 ku-MKV / MP4). I-Dolby Vision inamandla kakhulu — i-DV profile 5 / 7 / 8.1 ku-MPG ihlala kuphela ku-MKV nge-HEVC; ukushintsha ku-FLV isihlungi esingathwala i-DV layer ihamba phambili ku-HDR10.

MPG

I-MPG iyisandiso sefayela samafayela evidiyo e-MPEG-1 noma e-MPEG-2. Ngokuvamile isetshenziselwa ukudlalwa kwevidiyo nokusabalalisa.

FLV

I-FLV (I-Flash Video) ifomethi yesiqukathi sevidiyo eyakhiwe yi-Adobe. Ivamise ukusetshenziselwa ukusakazwa kwamavidiyo aku-inthanethi futhi isekelwa i-Adobe Flash Player.
