Indlela yokuguqula FLV kuya WebM

Isinyathelo 1: Layisha eyakho FLV amafayela usebenzisa inkinobho engenhla noma ngokuhudula bese uphonsa.

FLV kuya WebM Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani ikhowudi FLV ku WebM ngaphandle kokulahlekelwa ukhwalithi yevidiyo?

Layisha phezulu ifayela lakho FLV futhi umguquli uqhuba i-CRF-based re-encode ebhekisa ku-visually-lossless WebM output (CRF 18 ngokuzenzakalela, amaxabiso aphansi = ifayela elikhulu / umgangatho ophezulu). I-codec ikhethiwe ukufana ne-WebM container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines. 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. WebM idinga ukucophelela: VP8 noma VP9 ividiyo (AV1 manje) nge Vorbis noma Opus umsindo, futhi akukho okuthile okuningi.

Ingabe ngizongeza izihloko ezikhethiwe uma ifayela liyi WebM?

Yebo. FLV ayinaso isikhala esisetshenziswayo sesihloko esilula, ngakho isikhala sesihloko se FLV kufanele sifakwe kusithombe noma sithunyelwe njengefayela le-sidecar elilodwa. WebM sifaka isikhala sesihloko njenge-stream ekhethiwe, ngakho ngemuva kokuguqulwa ungafaka isikhala se-SRT okubonayo angashintsha, ashintshe noma aphinde ashintshe.

Ingabe i-WebM izodlala kwi-browser uma i-FLV ingadlalanga?

Yebo, futhi lokho kuyisizathu esiphelele sokuguqulwa. I FLV efakwe kwikhasi lewebhu ibonisa umdlali okhubazekile noma icindezela ukulayisha, ngoba iziphequluli azikho izikhombisi ezizo. WebM idlala ngaphakathi ngengxenye yevidiyo ye-HTML5 engavamile ngaphandle kweplugin noma kusetshenziswa okungaphandle. I-WebM idlala ngokusemthethweni kuwo wonke umsakazo omusha ngaphandle kweplugin, ngaphandle kwelayisense nemali yokuboshwa, okuyenza ibe yiphutha levidiyo efakwe kwi-web.

Ingabe kufanelekile ukushintsha ama-FLV ama-records adala ku-WebM?

Noma yini ofuna ukuyigcina, yebo. FLV ihlobene nohlobo oludlule lwevidiyo nesoftware efunda ngayo ihlala ihamba ihamba isuka kumafoni, iziphequluli nezinhlelo zokusebenza. Ukusuka kwevidiyo ku WebM manje, uma umqokeli ohlanzekile ukhona, kuyinto ehlukile phakathi kwegobo lomlando ongavula ngawo iminyaka eyisithupha nenye ongayenza. Akukho isiphequluli, ifoni noma i-TV ekhona engakwazi ukudlala i-FLV — noma yini ekhona kule bhokisi kumele ihunyushwe ngaphandle ukuze ihlale ibonakale.

Yini i-codec yevidiyo i WebM isebenzisa?

Kuxhomekeka ku WebM isiqoqi. MP4 iphutha ku-H.264 ukuze kuxhaswe ukusakazwa okubanzi phakathi kwamafoni, amabhuleki, nama-Smart TVs. MKV iphutha ku-H.265 / HEVC ukuze kufinyelelwe isigamu sesayizi yefayela ngekhwalithi elinganayo. WebM iphutha ku-VP9. Izinketho ezithuthukisiwe zibonisa ukhetho lwe-codec olucacile uma ufuna ukucima. I-WebM iyingxenye eqinile ye-Matroska eshicilelwe yi-Google ngo-2010 ekhethekile ekubeni i-HTML5 ividiyo ifakwe ibhokisi elikhululekile.

Ingabe umsindo wami uzohlala ukhona FLV kuya ku WebM?

Yebo. Uma FLV ne WebM bebelana nge-codec yomsindo (isibonelo, zombili zifaka i-AAC), umsindo uphinde uhlukaniswe ngaphandle kokuphindeka kokufaka uphawu — okufanayo. Uma ama-codecs ahluka, umsindo uguqulwa ku-AAC / Opus / Vorbis ngokuya ngoWebM ibhokisi lokusekela. Umsindo we-multi-track (umbono, izilimi ezihlukile) ugcinwa.

Ingabe ngigcina ifreyimu yesiqalo uma ngiguqula FLV ku WebM?

Ngokungajwayelekile yebo — i-24fps FLV ihlala i-24fps ku-WebM; i-60fps FLV ihlala i-60fps. Uma ufuna ukuguqula isilinganiso (isibonelo, i-interlaced 29.97 → progressive 30, noma i-60 → 30 uku-upload amalimi), isinqumo se-framerate siphatha 3:2 uku-pulldown, deinterlacing, ne-frame-blending ku-code pass efanayo.

Ingabe ubukhulu befayela bushintsha kanjani kusuka ku FLV kuya ku WebM?

Same-codec re-mux (FLV H.264 → WebM H.264 ushintsha isihlungi kuphela): ubukhulu obufana kakhulu. Ushintsho lwe-codec lungashintsha ngokujulile: H.264 → H.265 kufaka ihele ngengxenye ngaleyo khwalithi yokubuka efanayo; VP9 ifana kakhulu; AV1 ihlukanisa ezinye 20-30% kodwa ihamba kancane ukukopela.

Ingabe ihele WebM lizodlala ku-iPhone, Android, ne-Smart TVs?

MP4 / H.264 idlala ngokusemthethweni kuwo wonke amadivayisi amanje. MOV / H.264 idlala kumadivayisi we-Apple namanye ama-TV kodwa ahlala e-Android edlule. I-MKV idinga i-VLC ku-iOS. I-WebM iyisiphequluli sokuqala. Izinketho ezithuthukisiwe zifaka "ukuxhumana kwedivayisi" okusetshenzisiwe okukhetha i-WebM codec / ibhokisi eliphephile kakhulu lenjongo yakho. WebM ilungile encane noma kuphi ngaphandle kwe-browser - ama-video editors, amafoni 'ama-galleries asekhaya nama-Smart TVs ahlala engaziboni.

Ingabe kuthatha isikhathi esingakanani ukushintsha i-FLV ividiyo yehora elilodwa ibe yi-WebM?

I-same-codec re-mux ifinyelela ngokushesha — 30 kuya ku-60 imizuzwana yefayela lehora elilodwa. I-codec ephelele iphinde ikhodeke isebenza ngokuyisisekelo 0.3-0.7x isikhathi somthombo ku-GPU yethu, ngakho-ke i-1-hour FLV → WebM iphele ngemizuzu engu-18-40 ngokuya ngesinqumo ne-codec ethengiswayo.

Yini isixazululo esiphezulu esixhaswe yi FLV kuya ku WebM?

Kuze ku-8K (7680×4320) kuma-premium plans. Ukuguquka okumahhala kufinyelela ku-4K (3840×2160) ngobukhulu befayela ngalinye. I-HDR metadata (HDR10, HDR10+, Dolby Vision uma ikhona) idluliselwa lapho ama-FLV ne-WebM amabhokisi axhasa khona.

Ingabe i-FLV yami yevidiyo ifihlakele ngesikhathi sokuguqulwa ku-WebM?

Yebo. Amafayela wevidiyo alayishwe phezulu aphathwa emisebenzini ehlukanisiwe, angeke abonelwe umuntu, angeke afakwe kwi-index, futhi asuswa ngaphakathi kwemizuzu yokuqedwa. Ifasitela lokugcinwa libhalwe ku /privacy/ futhi asishicileli lutho oluqeqeshiwe oluvela ku-uploads womsebenzisi.
