Indlela yokuguqula FLV ukuba BMP

Inyathelo 1: Layisha eyakho FLV iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho BMP iifayile

FLV ukuba BMP Uguqulelo lwe FAQ

Ndizikhupha njani iifayili kwi-FLV video njenge-BMP imifanekiso?

Layisha phezulu ifayili FLV kwaye umguquli ubonisa umkhethi wesakhelo-sokukhupha: isakhelo ngasinye se-Nth, ii-frames kwi-timestamps ezichaziweyo, okanye i-frame enye ngesekondi. Isakhelo ngasinye esikhethiweyo sikhowudiwe njengefayili ehlukileyo ye BMP kwaye sidityaniswe njenge-ZIP yokukhuphela ezantsi.

Umfanekiso okhuphiweyo BMP uphuma njani kwisisombululo esipheleleyo?

Ugqibo olufanayo njenge-FLV ividiyo — umthombo we-1080p uvelisa i-1920×1080 BMP ii-frames; umthombo we-4K uvelisa i-3840×2160 BMP ii-frames. Yenza kwakhona ubungakanani emva kokukhupha ukuba ufuna ii-thumbnails ezincinci.

Ndingayikhupha isakhelo ngasinye kwifayili FLV njenge BMP?

Ewe, kodwa uqaphele ngobalo lwefayili - i-30fps 1-minute video ivelisa ii-frames ezili-1,800. Sizifaka kwi-ZIP archive ngokuzenzekelayo. Kwiiclip ezide sebenzisa ukhetho "1 ngesekondi" (i-frames ezili-60) okanye iziqinisekiso zexesha ezikhethekileyo.

Ingaba imifanekiso BMP iya kugcina umbala ophakamileyo FLV?

Ewe - umbala uguqulwa kwikhowudi nge-matrix efanayo esetyenziswa ngumboneleli FLV (BT.709 ye-HD, BT.2020 ye-4K HDR). Umboneleli we-HDR udweliswe nge-tone-mapping kwi-SDR xa ukhupha kwi-BMP (i-PNG / JPG ayikwazi ukugcina amanqanaba e-pixels e-HDR ngokusemthethweni).

Lithini ubungakanani befayili yesakhelo esitshatweyo BMP?

Kuxhomekeke kwisisombululo kunye nokhetho lwe-codec. I-1080p PNG frame yi-2-5 MB; i-1080p JPG quality-85 frame yi-200-500 KB. Yandisa ngokubala i-frame ukuze ubungakanani be-ZIP — kwinqanaba eliphezulu, ukususwa kwe-frame nganye ye-10-min 1080p video kwi-PNG yi ~50 GB.

Ingaba i-BMP ekhutshweyo igcina i-EXIF metadata yekhamera?

Isiqulathi seefayili FLV asigcinanga i-EXIF yesakhelo ngasinye ngendlela eyenza ikhamera ehlala ihlala, ngoko ke ii-BMP iifayili ziphuma nge-EXIF engenanto. Sifaka `creation_time` indawo ebonisa kwi-source frame timestamp ukuze uphinde ulungelelanise i-bundle.

Ithatha ixesha elingakanani ukususwa kwesakhelo ukusuka ku FLV ukuya ku BMP?

Ukukhupha isakhelo kukhawuleza - ngokuqhelekileyo 20- 30% yobude bomthombo kwindlela eqhelekileyo yokuhambisa. Imizuzu emi- 5 FLV → BMP iquka igqiba malunga nemizuzu emi- 1 ngaphandle kokubala isakhelo, kuba ibhotile yengxowa yi BMP encoder, hayi i demuxer.

Ndingazikhuphela iifayili kwixesha elikhankanyiweyo kwividiyo FLV?

Ewe - ukhetho oluphambili luyakwamkela uluhlu oluhlukaniswe nge-comma lweziqinisekiso zexesha (umzekelo `00:01:23,00:05:00,00:10:42`) kwaye luvelisa ifayile enye BMP ngesatifiketi sexesha ngalinye. Isetyenziswa kwizifundo ezincinci okanye iziganeko ezibhekisa kuzo.

Ingaba i-FLV yevidiyo yam ifihlakeleyo ngexesha lokukhupha isakhelo?

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngasinye. Ividiyo yombhalo kunye neefreyimu ezikhuphiweyo ziqhubekekiswa kubasebenzi ababekwe ngokuzimeleyo kwaye zicinywe kwimizuzu.

Kutheni iifayili zam ezikhuphiweyo BMP zimnyama?

I-motion blur ihlala ivela kumboneleli FLV (ikhamera yayihamba xa isakhelo sathathwa). Zama ukukhetha i-timestamps ukusuka kwimiboniso ehlala ikhona, okanye uthathe ii-frames ezininzi ezibekwe phantsi uze ukhethe ezicacileyo. I-pipeline ayiqwalaseli uqaqambo.

Ingaba le sixhobo sixhasa ukutsala isakhelo esinye ngasinye kutshintsho lwendawo yomboniso?

Akukho kutyibiliko olusisiseko - sebenzisa ukhetho "1 ngomzuzwana" njengokwenkxaso, emva koko ukhethe ngokubonakalayo iifayili zotshintsho lwendawo. Umqokeleli wokufumana indawo okhethekileyo ukwi-roadmap.

Ndingasebenzisa i-BMP isakhelo esikhutshweyo ngokurhweba?

Ewe, ngokuxhomekeke kwilayisensi elawula umthombo FLV imixholo. Utshintsho lwefomati aluyi kuzisa naziphi na izilumkiso — siza kudibanisa akukho phawu lwamanzi kwaye siza kuzisa naziphi na izilumkiso kwi BMP imveliso.

FLV

FLV yayisisiqulathi seefayili ecaleni kwevidiyo ye Flash kwi web, ngoku igqityiwe kodwa ihlala isetyenziswa kukukhuphela okudala kunye nokugcina.

BMP

Iifayile zeBMP zigcina imifanekiso kwifomathi yebitmap engacinezelwanga, nto leyo ebangela ukuba iifayile zibe nkulu kodwa zibe nomgangatho ogqibeleleyo.
