MKV ukuba HLS Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-MKV ibe yi-HLS ngaphandle kokubuyisela umbhalo ofihlakeleyo wevidiyo?

Xa i MKV ne HLS 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 HLS isiqulatho kwaye kutshintsha kuphela umgqomo. I-remux ye-1 GB MKV kwi HLS ihlala igqiba kwimizuzu eyi-5-15 ngaphandle kokufumana inzuzo yomgangatho. MKV yi-codec-agnostic: H.264, HEVC, VP9 ne-AV1 ividiyo ihlala ikhululekile ecaleni kwe-AAC, FLAC, Opus, DTS okanye i-Dolby audio kwifayili enye. Uthotho lwe-HLS luyi-.m3u8 ecacileyo ebonisa i-H.264 okanye i-HEVC equlethe iziqendu kwi-bitrates ezininzi, ngoko umdlali angatshintsha umgangatho phakathi kokudlala.

Ingaba i HLS iyadlala kwisikhangeli xa i MKV ayiyidlala?

Ewe, kwaye oko kuqhelekileyo isizathu esipheleleyo sokuguqula. A MKV efakwe kwiphepha le web okanye ibonisa umdlali olahlwayo okanye iforce ulwaleko, kuba ibrowser ayithuthinga i decoder kuyo. HLS idlala kwilayini esuka kwi HTML5 eqhelekileyo isixhobo sevidiyo ngaphandle koplugin kwaye akukho sicelo sengaphandle. I-HLS ilungelelanisa ububanzi be-bandwidth yombukeli kwixesha elibonakalayo kwaye yifomati yokusasaza kuphela i-Safari kunye ne-iOS exhasa ngokusemthethweni.

Ingaba i HLS iquka isiqulathi seefayili okanye i-codec, kwaye ngaba itshintsha into endiyifumanayo kwakhona?

Itshintsha into elindelekeyo kwifayile yemveliso. Icala elinye loguqulelo libiza ukukhowuda kunokuba ujikeleziso, ngoko oko kubuyela umva kukujikelezo lweebit ngaphakathi komgquba olungeleyo - ngokuqhelekileyo MP4 okanye MKV. Ulwandiso lubonisa umgquba; i codec yiyo eyaziyo ubungakanani befayile kwaye apho izakudlalwa khona.

Ingaba i-audio enezithotho ezininzi izakuhlala iphila ukuguqulwa kwe-MKV ukuya kwi-HLS?

Ewe - yonke i-audio track kwi MKV (umbono womlawuli, iilwimi ezitshintshiweyo, i-audio echazayo) igcinwa kwi HLS 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. I-HLS yi-Apple's HTTP Live Streaming - hayi ifayili kodwa i-playlist kunye nesiqulathi seefayili sezona ndawo zifutshane zemidiya.

Ingaba iingoma zesicatshulwa zigcinwa xa uguqula MKV ukuya ku HLS?

Izihloko eziphantsi ezicocekileyo (iingoma ezikhethiweyo) zihlala zikhona xa HLS zingazithabatha: i-MKV igcina i-SRT, i-ASS, i-SSA, i-PGS, i-VobSub ngokusemthethweni; i-MP4 igcina kuphela i-mov_text (ifomati ethe tyaba). 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.

Ingaba MKV ukuya ku HLS igcina abaphawuli besahluko / ulawulo olufana ne-DVD?

I-metadata yesichazi-magama idlulisa phakathi kwe-MKV ne-HLS xa zombini iziqulatho zixhasa isichazi-magama se-atomic (MKV, MP4, MOV). 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-HLS yenza ifayili engachazi-magama ngaphandle kokuba udibanisa abaphawuli ngesandla.

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

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 MKV ukuya kwi HLS ushiya ezi fayili zifakiwe xa i-HLS ayiyiyo i-MKV — i-elementary streams iguqula, kodwa umthwalo odityanisiweyo uhlala kummthombo. Gcina i-MKV njengengxelo yangaphambili ukuba uxhomekeke kwifonti ezifakelweyo.

Yeyiphi i-codec esetyenziswa yi-HLS kwimveliso ngokumiselweyo?

I-codec emiselweyo ikhethiwe ukuhambelana ne HLS 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. HLS ayiyiyo ifayile elula elayishwe ezantsi - ukugcina ingekho kwi-intanethi kufuneka iphinde

I-HDR (HDR10, Dolby Vision) ihlala njani MKV ukuya ku HLS?

I-HDR metadata ehlala njalo (i-HDR10 ibonisa amaxabiso aphezulu, umphakamo ophezulu wokukhanya kwezinto eziquletheyo) ihamba phantsi ukuya kwi-HLS 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-MKV ihlala kuphela kwi-MKV ene-HEVC; ukutshintsha kwi-HLS isiqulatho esingathwali umbala we-DV ihamba phantsi ukuya kwi-HDR10.

Ingaba i-MKV ukuya kwi-HLS igcina i-framerate eguqukayo (VFR)?

MKV ne WebM zirekhoda i-frame nganye yexesha elipheleleyo kunye nokuphatha i-VFR ngokusemthethweni, ngoko ke i-MKV VFR ihlala kwi-HLS yale fomati ngaphandle kokuphindaphinda. I-MP4 igcina i-timestamps ngokusemthethweni kodwa abanye abadlali bakholelwa ukuba i-CFR; umguquli ubonisa "ubunzima be-CFR" ukutshintsha okubuyisela i-VFR MKV ukuya kwi-24 / 30 / 60 fps HLS kwiinjongo ezinomngcipheko.

Kutheni i-HLS ifayili yam incinci / ikhulu kune-MKV emva kokuguqulwa?

I-remux ye-codec efanayo ivelisa ubungakanani obufanayo (i-container overhead ihluka nge-0.1-2%). Utshintsho lwe-codec lunokutshintsha ubungakanani nge-50% okanye ngaphezulu: H.264 ukuya kwi-H.265 ngokuqhelekileyo iqulethe ifayili kwinqanaba elifanayo lomgangatho wokubona; H.264 ukuya kwi-AV1 iqulethe kwakhona kwi-preset ecocekileyo. Ukusuka kwi-bitrate ephezulu MKV (Blu-ray rip) ukuya kwi-bitrate ephantsi HLS (ukukhuphela kwi-web) yisizathu esiqhelekileyo sokuhla okuphezulu.

Ingaba i-MKV ukuya kwi-HLS iguqula i-4K / 8K / 60fps iqulethe?

Ewe ukuya kwi-8K (7680x4320) kwi-Premium. Umphakamo okhululekileyo uphatha i-4K (3840x2160) ukuya kwi-1 GB yefayili. I-pure remuxes (i-codec efanayo edlulayo) ye MKV enkulu kwi-HLS imiselwe yi-disk I/O, hayi i-CPU — i-30 GB MKV iqhelekileyo i-remuxes kwi-HLS ngaphantsi komzuzu ngaphandle kokuxhomekeka kwi-resolution. I-re-encodes i-scale nge-pixel count.

MKV

I-MKV (Matroska) inokugcina iividiyo, iaudio, kunye neengoma ezingezantsi ezingenamda kwifayile enye, efanelekileyo kwiimuvi.

HLS

I-HLS (i-HTTP Live Streaming) yiprotocol yokusasaza eyenziwe yi-Apple yokuhambisa umxholo weaudio kunye nevidiyo kwi-intanethi. Inika usasazo oluguquguqukayo ukwenza ngcono ukudlala kwakhona.
