AVI kuya FLV Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Uma ama-AVI 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 AVI ku-FLV ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. Amafayela we-AVI adlule ama-codecs amanje: cabanga i-MPEG-4 Part 2 (DivX/Xvid), Motion JPEG noma amafreyimu amnyama angacindezelwa ngaphandle kwe-H.264. 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-AVI yami ibonisa ama-comb lines ekuhambeni - ngabe lokhu kuzodluliselwa ku-FLV?

Kuzokwenzeka uma ungasebenzisi i-deinterlace, futhi AVI 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. AVI Microsoft Audio Video Interleave, isungulwe ngo-1992 phezu RIFF chunk format - eyodwa yezinto eziphilayo ezidala kakhulu okwamanje e circulation.

I-AVI yami yokurekhoda ihlukaniswe ibe yizingxenye ezinombhalo - i FLV inezinga elifanayo?

Hayi, futhi lokhu kuyisizathu esingcono sokushintsha. I AVI iqukethe i-file eyodwa esebenza kahle eyenza ukurekhodwa okude noma okuphezulu kwe-bitrate kuhambe ngokuqondile, okuyinto ebangela ukuthi ukurekhodwa okudala kufike njengengxenye1, ingxenye2, ingxenye3. FLV ayinaso isibopho esifanayo, ngakho ama-pieces angaxhunywa kabusha kwifayela elilodwa eliqhubekayo. I-AVI ayinaso isixhaso esisemthethweni se-codecs yamanje, isilinganiso sefreyimu esiguqukayo, izihloko ezithambile noma amafayela angaphezu kuka-4 GB ngaphandle kokuhlaselwa, futhi i-chunk ngayinye i-overhead ibhoboza ifayela.

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

Akunakuthembeka. AVI 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. AVI ilula kakhulu, okuyinto ngokucacile kungani ama-camcorders akudala, amakhadi okuqoqa, DVD amathuluzi okukhishwayo kanye Windows-era software wonke akhona akhipha. Akukho isiphequluli, ifoni noma i-TV ekhona engakwazi ukudlala i-FLV — noma yini ekhona kule bhokisi kumele ihunyushwe ngaphandle ukuze ihlale ibonakale.

Ingabe kukhona okushintshayo phakathi kwefomethi ezimbili ezidalayo njenge AVI 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.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa AVI kuya ku FLV?

Yebo — wonke umculo ohambayo ku AVI (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 AVI 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 AVI kuya ku FLV igcina iziphawuli zesiga-nyezi / ukuzula kwe-DVD-style?

Isigaba se-metadata sidlulisa phakathi kuka AVI 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 AVI 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-AVI kuya ku-FLV ushiya lezi zifomethi lapho i-FLV ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-AVI 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 AVI 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-AVI ihlala kuphela ku-MKV nge-HEVC; ukushintsha ku-FLV isihlungi esingathwala i-DV layer ihamba phambili ku-HDR10.

Ingabe i AVI kuya ku FLV igcina ifreyimu eshintshayo (VFR)?

MKV ne WebM zirekhoda ama-timestamps we-frame ngayinye futhi ziphatha i-VFR ngokusemthethweni, ngakho-ke i-AVI VFR ihlala i FLV yalezi fomu ngaphandle kokuphindeka kokuhlolwa. I-MP4 igcina ama-timestamps futhi kodwa abanye abadlali bakholelwa ukuthi i-CFR; umguquli ubonisa "u forza CFR" ukushintsha okuphinda ukuhlolwa kwe-VFR AVI kuya ku-24 / 30 / 60 fps FLV ngezinhloso ezinomthelela.

AVI

Amafayela e-AVI angaqukatha idatha yomsindo nevidiyo, esekelwa kabanzi kodwa enosayizi abakhulu bamafayela.

FLV

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