Indlela yokuguqula FLV kuya BMP

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

Isinyathelo 2: Chofoza inkinobho ethi 'Guqula' ukuze uqale ukuguqulwa.

Isinyathelo 3: Landa i-version yakho BMP amafayela

FLV kuya BMP Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngizokhipha kanjani amafreyimu kusuka ku FLV ividiyo njenge BMP izithombe?

Layisha phezulu i-FLV futhi umguquli ubonisa isikhethi sefreyimu-sokukhipha: nganoma iyiphi ifreyimu ye-Nth, amafreyimu ezikhathini ezicacisiwe, noma ifreyimu eyodwa ngesekondi. Ifreyimu ngayinye ekhethiwe ikhodwe njengehele BMP elilodwa futhi isethulo esigcwele sifakwe kwi-ZIP archive yokulayisha phezulu. FLV yi-Flash Video container ephethe yonke i-web video kusukela ngo-2003 kuze kube yilapho i-Flash ikhubazekile ekugcineni kuka-2020. I-BMP yiWindows Bitmap, ifomethi ye-raster engaqondakali efakwe ku-Windows kusukela ngo-1985.

Ingabe ngithola ama-BMP amafreyimu ngaphandle kwesihloko esingezansi?

Uma nje i FLV ayizange itshetshezwe, ngoba FLV ayinaso isingeniso esikhethiwe sohluzo esikhethiwe sokuvala. Noma yini eFLV ebonisa esigabeni isithombe, ngakho i BMP ngayinye ikhiqiza ukukhishwa futhi akukho sinqumo esisusayo ngemuva. lapho ihele elihlukile lesihloko likhona eduze kwevidiyo, khipha kusuka emthonjeni ogcina ama-2 ahlukene futhi ama-frames aphuma ahlanzekile. Akukho isiphequluli, ifoni noma i-TV ekhona engakwazi ukudlala i-FLV — noma yini ekhona kule bhokisi kumele ihunyushwe ngaphandle ukuze ihlale ibonakale.

Ingabe amafayela BMP azokhula kangako?

Okuningi kunalokho okubonayo, ngoba BMP igcina wonke ama-pixel ngokugcwele kungafani nokulinganisela. I-1080p ihlala ifinyelela ku-2-5 MB futhi i-4K ihlala ifinyelela ku-6-15 MB, ngakho-ke ukukhishwa okude kusebenza ngokushesha. Lokhu kuyibhizinisi elilungile uma izithombe zidla ukukhiqizwa okuqhubekayo, futhi okubi uma zihamba ngqo kwikhasi le-web. I-BMP igcina imiqulu ye-pixel engacindezelwanga ngokuphelele ngesihloko esincane, ngakho-ke kulula ukuyihlukanisa.

Ngasiphi isixazululo siphuma kuso sonke ifreyimu ekhishwayo BMP?

Isinqumo esifanayo njenge FLV ividiyo — 1080p FLV ikhiqiza amafreyimu angama-1920×1080 BMP; 4K FLV ikhiqiza amafreyimu angama-3840×2160 BMP. Sebenzisa ukuguqula usayizi ngemuva kokukhipha uma ufuna amathumbnail amancane noma ama-social-media-size crops.

Ingabe ngizokhipha ifreyimu ngayinye kusuka ku FLV njenge BMP?

Yebo, kodwa uqaphele ngokubalwa kwefayela - i-30fps 1-minithi FLV ikhiqiza amafreyimu angama-1,800 BMP. Siwafaka ngokuzenzakalela ku-ZIP. Kweziclips ezide, "1 ngesekondi" (ifreyimu engu-60) noma ama-timestamps athile anikeza imiphumela elawulwayo.

Ingabe izithombe ezikhishwayo BMP zizogcina umbala olinganiselwe FLV?

Yebo — umbala uqoshwe nge-matrix esetshenziswa umsuka FLV (BT.709 for HD, BT.2020 for 4K HDR). Ama-HDR asuka ku-tone-mapped ku-SDR uma ekhishwa ku-BMP ngoba ama-BMP ahlukahlukene (PNG, JPG) angagcina ama-pixels we-HDR ngokusemthethweni.

Yini ubukhulu behele lwesiphequluli esikhishwayo BMP?

Kuxhomekeka kusinqumo kanye ne-BMP codec. Ifreyimu ye-1080p PNG ivame ukuba yi-2 kuya ku-5 MB; i-1080p JPG esezingeni-85 i-200 kuya ku-500 KB; i-4K PNG i-6 kuya ku-15 MB. Ekugcineni, ukukhipha i-PNG nganoma iyiphi ifreyimu yemizuzu engu-10 1080p FLV kukhiqiza ~50 GB jikelele.

Ingabe i-BMP ekhishwayo igcina i-EXIF camera metadata?

I FLV i Container ayigcinanga i-EXIF nge-frame ngendlela ikhamera ehlala isebenza ngayo, ngakho i BMP ifaka amafayela ngaphandle nge-EXIF engenanto. Sifaka i-`creation_time` field ekhombisa i-source frame timestamp ukuze uphinde uhlanganise i-bundle ngokulandelelana kokuthatha.

Ithatha isikhathi esingakanani ukukhishwa kwefreyimu kusuka ku FLV kuya ku BMP?

Ukukhishwa kwefreyimu kushesha — 20 kuya ku-30% yesikhathi somthombo ku-pipeline ejwayelekile. Iminithi engu-5 FLV → BMP iqoqo liphelela cishe ngomzuzu owodwa kungakhathaliseki inani lefreyimu, ngoba ibhodlela liyi-BMP encoder, hhayi i-FLV demuxer.

Ingabe ngizokhipha amafreyimu eziqephuni ezikhethekile zesikhathi ku FLV?

Yebo - ukhetho oluphezulu lu accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one BMP file per timestamp. Useful for chapter thumbnails, scene reference shots, or thumbnailing long lectures.

Ingabe i-FLV yami yevidiyo imfihlo ngesikhathi sokukhishwa kwefreyimu?

Yebo — imodeli yobumfihlo efanayo nezo zonke iziguqulo. Ividiyo yomsuka kanye nefreyimu ekhishwayo BMP ziqhubekelwa ngabasebenza ngokuzimela futhi zicishwe ngaphakathi kwemizuzu; akukho kuhlolwa komuntu, akukho kuhlolwa kokuzivocavoca, akukho ukungena kwengxenye yesithathu.

Kungani ama-BMP amafreyimu ami akhishwa amnyama?

Kuyinto evamile ukushaya kwekhanda lokushaya okuthosiwe ku-FLV - ikhamera noma isithako sahamba lapho ifreyimu ithathwa. Khetha ama-timestamps kusuka emibonweni ehlala njalo, noma khipha amafreyimu azungeze futhi ukhethe ocacile kakhulu. Ipayipi alikhiqizi imininingwane engakhona.

FLV

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