M4V ukuba FLV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4V ibe yi-FLV ngaphandle kokubuyisela umbhalo ofihlakeleyo wevidiyo?

Xa i M4V ne FLV iziqulatho zingathatha zombini i-codec efanayo (H.264, H.265, VP9, AV1), umguquli ubuyela umva kwi-remux: imijelo ephambili ikhopiwe i-byte-nge-byte kwi FLV isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB M4V kwi FLV ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. Ngokusisiseko i-M4V yi-MP4 — H.264 okanye HEVC nge-AAC — ene-Apple FairPlay DRM ekhethiweyo kunye ne-iTunes isithuba se-metadata. I-FLV ihlala igcina i-Sorrenson Spark okanye i-H.264 video ene-MP3 okanye i-AAC yesandi, ejikelezwe kwifomati yokuhamba eyenziweyo yokuhambisa i-RTMP.

Yintoni eyenza i-subtitle tracks kwifayili yam M4V?

Ayikwazi ukuhlala ikhethiwe, kuba FLV ayinayo i-soft-subtitle stream ukubeka i-subtitles. Zikhona iindlela ezimbini zokuphuma: ukutshabalalisa kwividiyo ngexesha lokuguqula, okwenza ukuba zihlala zihlala kwaye zingatshintshwa, okanye urhweba ngaphandle njenge.srt eyahlukileyo ecaleni kwe FLV ukuze umdlali alayishe. Umguquli uthetha ukuba yintoni eyayenza kunokuba ikhuphe ngokucokisekileyo. Akukho mkhangeli zincwadi, ifowuni okanye iTV iya kudlala i-FLV - nantoni na esele ikwi-container kufuneka ishenxiswe ngaphandle ukuze ihlale ibonakale.

I M4V yam inezinto ezininzi ezidlala umculo - ngaba zonke ziya kuhlala zikhona kwi FLV?

Ayithembekanga. M4V igcina imijelo emininzi yesandi njengemizila yohlobo lokuqala, kodwa FLV uxhaso lokudlala ngaphezulu kwemizila yokuqala ayihambelani, ngoko abadlali abaninzi baya kutyhila kuphela enye. Khetha imizila oyifunayo phambi kokuguqula; abanye bangcono ukutywina kwifayile zabo ezikhethekileyo kunokuba bashiye kwisiqulathi seefayili esifihlayo. I-M4V igcina abaphawuli besiqendu, umsebenzi wobugcisa kunye nengoma yesihloko esingaphantsi kwisimo i-Apple TV app ilindeleyo, eyona MP4 iqhelekileyo ihlala ilahlekelwa yiyo.

FLV ihlala ibuyela umva kwisoftware yokukhowudi kwihardware efanayo - ubunzima be CPU obuphezulu, isixhobo esishushu, kunye neeframes ezikhuphekayo kwi-4K material. Kwisixhobo esimiselweyo, M4V yindawo ekhuselekileyo yokugcinwa ehlala kuyo.

Yintoni eyenza i-5.1 surround audio xa iguqula M4V ukuya FLV?

I-stereo iqhutywa phantsi, kuba FLV ayinayo indlela ethembekileyo ye-multichannel. Ukujika ezantsi kusetyenziswa i-ITU eqhelekileyo esebenza ngokufanayo ukuze unxibelelwano kwisiqhagamshelanisi esiphakathi sihlale siqondakalayo kwaye i-circumstances ifike kwinqanaba eliphantsi kunokuba iphele. Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo siphelile emva koko.

Kutheni ndiyiguqula i M4V ibe yifomati edala njenge FLV?

Kuba isixhobo esininzi sekhompyutha asizange sifunde nantoni na entsha kwaye asizukufunda. Abadlali be DVD, iiyunithi zemoto eziphambili, iimo zokubukela i-camcorder, imboniselo yeshishini kunye nezixhobo ezininzi zosasazo lweemveliso zixhasa FLV kwaye akukho nto enye. Uguqulelo luya kugqiba inqanaba ezantsi kwimpumelelo, ithengiswe ukutshintshela ukusebenza kwisixhobo esingakho enye indlela yokukhetha. I-FLV's ephantsi ngepakethi nganye i-overhead iyenze igqibelele kwi-streaming ngaphezulu konxibelelwano olungathembekiyo lwexesha lakhe, kwaye ii-archives ezinkulu zayo zihlala zikhona.

Ingaba i-audio enezithotho ezininzi izakuhlala iphila ukuguqulwa kwe-M4V ukuya kwi-FLV?

Ewe - yonke i-audio track kwi M4V (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi FLV xa isiqulathi seefayili esithe nkqo sixhasa i-audio ejikelezayo-eninzi. I-MKV ne-MOV ziphatha ii-audio tracks ezingaqhelekanga; i-MP4 ixhasa ezininzi kodwa abanye abadlali behardware babona kuphela i-track 1; i-WebM icapisiwe kwi-Opus / Vorbis track enye. FLV yindawo yokugcina i-Flash Video ehambisa yonke i-web video ukusuka ngo-2003 de i-Flash ivale ekupheleni konyaka ka-2020.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula M4V ukuya ku FLV?

Ukutshintsha i-MKV enezihloko eziphantsi ze-ASS zibe yi-MP4 kuya kuzisa iindidi eziphantsi kwi-mov_text okanye ukutshabalalisa. Iisihloko ezinzima (eziqhutywe kwividiyo) zithatha ngaphezulu nokuba kunjalo.

I-WebM igcina isichazi-magama kwi-Matroska-compatible block, ngoko ke i-MKV <-> i-WebM isichazi-magama sihamba ngokucocekileyo. I-AVI ayinasichazi-magama esichaziweyo, ngoko ke ukuguqula i-AVI ibe yi-FLV yenza ifayili engachazi-magama ngaphandle kokuba udibanisa abaphawuli ngesandla.

Yintoni malunga neziqulathi zeefayili ze-MKV (ifonti, umzobo wesiqulathi seefayili) xa usiya kwi M4V ukuya kwi FLV?

MKV yindawo yokugcina i-mainstream kuphela egcina iifayile ezifakiwe ngokuzithandela (ifonti ze-TTF ze-ASS subs, ubugcisa be-JPG cover, i-fan-translated PDF inserts). Ukusuka kwi M4V ukuya kwi FLV ushiya ezi fayili zifakiwe xa i-FLV ayiyiyo i-MKV — i-elementary streams iguqula, kodwa umthwalo odityanisiweyo uhlala kummthombo. Gcina i-M4V njengengxelo yangaphambili ukuba uxhomekeke kwifonti ezifakelweyo.

Yeyiphi i-codec esetyenziswa yi-FLV kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne FLV isiqulathi seefayili ngokukhuselekileyo: MKV imiselwe ku-H.265 (HEVC) ukufezekisa ukucinezela okungcono; MP4 imiselwe ku-H.264 ukufezekisa inkxaso yesixhobo esibanzi; WebM imiselwe ku-VP9; AVI isebenzisa i-MPEG-4 ASP (DivX/Xvid lineage). Nciphisa nge-codec ephambili esuka ezantsi — AV1 ifumaneka kwi-MKV / WebM apho ufuna khona ukucinezela okuphezulu kwaye ungalindela ukungenisa ikhowudi.

I-HDR (HDR10, Dolby Vision) ihlala njani M4V ukuya ku FLV?

I-HDR metadata ehlala njalo (i-HDR10 ibonisa amaxabiso aphezulu, umphakamo ophezulu wokukhanya kwezinto eziquletheyo) ihamba phantsi ukuya kwi-FLV xa zombini iziqulatho kunye ne-codec ekhethiweyo ixhasa (HEVC, AV1 kwi-MKV / MP4). I-Dolby Vision inamandla ngakumbi — i-DV profile 5 / 7 / 8.1 kwi-M4V ihlala kuphela kwi-MKV ene-HEVC; ukutshintsha kwi-FLV isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.

M4V

I-M4V yifomati yefayile yevidiyo ephuhliswe nguApple. Iyafana neMP4 kwaye iqhele ukusetyenziselwa ukudlala ividiyo kwizixhobo zeApple.

FLV
