FLV kuya WMV Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Uma ama-FLV ne-WMV amabhokisi angaba nesixhumi esifanayo (H.264, H.265, VP9, AV1), umguquli ubuyela emuva ku-remux: ama-streams aphansi akopiwe ngo-byte-by-byte ku-WMV ibhokisi futhi ushintsho lwe-wrapper kuphela. I-remux ye-1 GB FLV ku-WMV ivame ukuqedwa ngamasekondi angama-5-15 ngaphandle kokulahlekelwa umgangatho. 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. WMV ithatha Microsoft VC-1 noma WMV3 video nge WMA audio - codecs cishe akukho ngaphandle Windows decodes natively.

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

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. Akukho isiphequluli, ifoni noma i-TV ekhona engakwazi ukudlala i-FLV — noma yini ekhona kule bhokisi kumele ihunyushwe ngaphandle ukuze ihlale ibonakale. WMV ngokuphumelelayo iphele efile: macOS, iOS, Android kanye nesipiliyoni ngasinye idinga isithathu-party decoders, futhi ezinye WMV amafayela zithwala DRM ukuthi akufanele kushintshwe ngaso sonke isikhathi.

Ingabe umsindo ogcwele uzoqhubeka nokuguqulwa FLV kuya ku WMV?

Yebo — wonke umculo ohambayo ku FLV (umbono womqondisi, izilimi ezihlukile, umculo ochazayo) ugcinwa ku WMV 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. WMV Windows Media Video, Microsoft ASF-based format kusuka Windows XP isikhathi.

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

Izihloko ezincane ezilula (izihloko ezikhethiwe) zihlala lapho WMV 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 FLV kuya ku WMV igcina iziphawuli zesiga-nyezi / ukuzula kwe-DVD-style?

Isigaba se-metadata sidlulisa phakathi kuka FLV no WMV 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-WMV kwenza ifayela elingahlukanisiwe ngaphandle kokuthi uhlanganise iziphawuli ngesandla.

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

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-FLV kuya ku-WMV ushiya lezi zifomethi lapho i-WMV ingakho MKV — ama-streams aphansi aguqulwa, kodwa umthwalo oxhunywe uhlala emsuka. Gcina i-FLV njenge-backup uma uhlala ubheke izifomethi ezixhunywe.

Yini i-codec esetshenziswa yi-WMV ngokuzenzakalela?

I-codec ejwayelekile ikhethiwe ukufana ne WMV 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. WMV icindezela kahle ngenxa yobudala bayo futhi ihlala ifomu PowerPoint, Windows edlule screen recorders kanye corporate media libraries ulindele.

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

I-HDR metadata ehlala njalo (i-HDR10 mastering display values, max content light level) ihamba phambili ku-WMV 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-FLV ihlala kuphela ku-MKV nge-HEVC; ukushintsha ku-WMV isihlungi esingathwala i-DV layer ihamba phambili ku-HDR10.

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

MKV ne WebM zirekhoda ama-timestamps we-frame ngayinye futhi ziphatha i-VFR ngokusemthethweni, ngakho-ke i-FLV VFR ihlala i WMV 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 FLV kuya ku-24 / 30 / 60 fps WMV ngezinhloso ezinomthelela.

Kungani ihele lami WMV lincane / likhulu kuna FLV ngemuva kokuguqulwa?

I-remux ye-codec efanayo ikhiqiza ubukhulu obufana kakhulu (i-container overhead ihluka ngo-0.1-2%). Ushintsho lwe-codec lungashintsha ubukhulu ngo-50% noma ngaphezulu: H.264 kuya ku-H.265 ngokuvamile kushiya ihele ngaphesheya ngekhwalithi efanayo yokubuka; H.264 kuya ku-AV1 kushiya ihele ngaphesheya futhi ngesinqumo esihamba kancane. Ukusuka ku-high-bitrate FLV (Blu-ray rip) kuya ku-low-bitrate WMV (ukufaka iwebhu) kuyisizathu esivame kakhulu sokulahlekelwa okuningi.

Ingabe i-FLV kuya ku-WMV iphatha okuqukethwe kwe-4K / 8K / 60fps?

Yebo kuze kube yi-8K (7680x4320) ku-Premium. Izinga elimahhala liphatha i-4K (3840x2160) kuze kube yi-1 GB yehele. I-pure remuxes (i-codec efanayo edlula) ye FLV enkulu iye ku-WMV iphele ngokudluliswa kwediski I/O, hhayi i-CPU — i-30 GB FLV ivame ukudluliswa ku-WMV ngaphansi kwemizuzu ngaphandle kokuqhathaniswa nesinqumo. Iphinde ikhode isilinganiso ngenani le-pixel.

Ingabe ihele lami FLV liyimfihlo ngesikhathi sokuguqulwa WMV?

Yebo — amafayela alayishwe phezulu FLV aphathwa ngabasebenzi abahlukanisiwe futhi asuswa emizuzwini edlulele. Sizohlala sibheka, sigcina, sigcina, noma sihlanganisa okuqukethwe. Bona /privacy/ ngefasitela lokugcinwa kwedatha. Ukuguqulwa kwepayipi luyasebenza kumathuluzi esiwalawulayo kusukela ekuqaleni kuya kukuphela; akukho i-API yeqembu lesithathu ethola ifayela lakho. FLV's low per-packet overhead yenze it okungcono e streaming phezu ukuxhumana unreliable yesikhathi sayo, futhi amafayela amakhulu yayo akhona.

FLV

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