VOB → MKV

Ewe. imixholo ye VOB ihlala idityaniswa, kuba ifomati ivela kwixesha le broadcast ne DVD, kwaye lo mguquli unenketho engadityaniswanga, ngoko ucombing uhambisa kwi MKV. Ukuba kubaluleke, dibanisa i VOB kuqala kwisixhobo se desktop njenge HandBrake okanye ffmpeg (icebo lokucoca ulwelo le yadif). I-VOB yi Video Object Container efumaneka kwi VIDEO_TS ulawulo lwe DVD nganye — i MPEG-2 inkqubo yokuhamba nge DVD-ekhethekileyo yokukhangela idata efakwe.

Hayi, kwaye le yenye yezona zizathu zilungileyo zokushenxisa. I VOB isiqulathi siqulethe ifayile enye esebenzayo ethe tyaba eyenza ushicilelo olude okanye oluphezulu-bitrate luqhube ngokuthe ngqo, oko kukuthi, kutheni ushicilelo oludala lufika njengenxalenye1, ingxenye2, ingxenye3. MKV ayinalo umda ofanayo, ngoko ke iinxalenye zingadityaniswa kwakhona kwifayile enye eqhubekayo. I-VOB ihlukaniswe phakathi kweefayili, ingafihliwe nge-CSS, kwaye ihambisa iipakeji zokhangelo eziphazamisa abadlali abafunayo.

Iifayile ze VOB zifihliweyo kwinqanaba le bitstream yindawo yokurhweba okanye isoftware ekhupha ifayile, kwaye umjelo ofihliweyo awunakucodwe sisi okanye ngantoni na ngaphandle kwesitshixo selayisensi. Iifayile ozirekhode, ozirhwebe ngaphandle okanye ozikhuphele ezantsi azikhuselwanga ziguqula ngokuqhelekileyo; ukuthengiswa kwelayisensi akuyi kwenza njalo, kwaye akukho mguquli uthembekileyo okwaziyo ukuthembisa okuthile.

Ingaba ayikwazi. VOB ikhowudiwe yisilicon ekhethekileyo kwifowuni, iitablethi kunye neeTV, nto leyo eyenza ukuba idlala ngaphandle kokutyibilika kwebhetri. MKV ihlala ibuyela umva kwisoftware yokukhowudi kwihardware efanayo - ubunzima be CPU obuphezulu, isixhobo esishushu, kunye neeframes ezikhuphekayo kwi-4K material. Kwisixhobo esimiselweyo, VOB yindawo ekhuselekileyo yokugcinwa ehlala kuyo. MKV ayinaso nasiphi na isixhaso sehardware esisemthethweni - iifowuni, iziphene kunye neeTV zihlala zifuna i-VLC okanye i-remux phambi kokuba zidlale.

Ukuba ufuna ukugcina into, ewe. VOB ibhekisa kuhlobo oludlulileyo lwezixhobo zevidiyo kwaye isoftware efunda i-video ihlala iphela kwifowuni, iziphene kunye nenkqubo yokusebenza. Ukushenxisa imifanekiso kwi MKV ngoku, ngelixa i-decoder ecocekileyo ikhona, kuhlukile phakathi kovimba onokuthi uvule kwiminyaka elishumi kunye noyena awukwazi. I-MKV yindawo yokugcina ekhethiweyo kuba igcina iingoma zesandi ezingaphelelanga, izihloko eziphantsi ezicocekileyo, abaphawuli besiqendu kunye nobugcisa bokuqhoboshela kwifayili enye.

Iinkqubo ezininzi zokuguqulela zigcina umculo omnye wesandi, omnye oneendawo ezininzi (oqhelekileyo uthelekiso oluphambili), uphinde ukhowudiwe kwi MKV isiqulathi, ngoko ke uluhlu lweenkcukacha kunye nolunye udidi lwesivakalisi sengoma zilahliwe. AVI, WMV, MPEG, FLV, VOB kunye ne M4V ukuya kwi MKV zigcina yonke imiculo, kwaye njalo i MP4 ukuya kwi MOV. Ukugcina umculo ohlukileyo, yenza i remux ye VOB ngomsebenzi wokuqala (i-VLC okanye i-ffmpeg ingakwenza oku), emva koko uyiguqule. MKV yi Matroska, ibhokisi evulekileyo eyenziwe ngo 2002 ngaphandle kweengxaki zonikezelo lwelayisensi kunye nokungaphelelanga kwinto engayigcinayo.

Kwiiperi ezithile. I-MP4 ukuya kwi-MOV igcina yonke i-track yombhalo ophantsi. I-AVI, i-WMV, i-MPEG, i-FLV, i-VOB ne-M4V ukuya kwi-MKV igcina yonke i-track yombhalo ophantsi: i-subtitles yombhalo ikhopiwe okanye iguqulwe kwi-SRT, kwaye i-subtitles esekelwe kwimifanekiso efana ne-DVD okanye i-Blu-ray ikhopiwe njengezi. I-MP4, i-MOV ne-WebM ukuya kwi-MKV igcina kuphela i-track yokuqala yombhalo ophantsi (njengo-ASS), ne-MP4 ukuya kwi-WebM igcina enye yokuqala njenge-WebVTT. Ezinye iiperi, kubandakanya i-MKV ukuya kwi-MP4 okanye i-MOV ne-WebM ukuya kwi-MP4, zikhupha i-tracks yombhalo ophantsi, kwaye umguquli awuzikhuphi kwimifanekiso. Ii-subtitles ezikhe zakhutshwa zihlala, kuba ziyinxalenye ye-frames yevidiyo.

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

Oku kuxhomekeke kwi-MKV container. I-MP4, MOV ne-MKV output isebenzisa i-H.264, edlala kwifowuni yonke, umkhangeli zincwadi neTV. I-WebM output isebenzisa i-VP9. I-AVI, WMV ne-MPEG output isebenzisa ii-codecs ezidala ezo fomati zaphuhliswa kuzo.

Akukho HDR yokusebenza okanye iimaphu zombala. Xa umjelo wevidiyo ukhopiwe (MKV ukuya kwi MP4 okanye MOV ngemimiselo emiselweyo), i-HDR10 idlula njengeyona. Xa ividiyo iphinde ikhowudiwe, i-HDR10 mastering metadata ilahliwe kwaye i-Dolby Vision okanye i-HDR10+ data ayigcinwanga, kwaye ngoBunjani, Ubunzulu okanye ucwangciso lwe-Frame Rate ezinye iipere ziyikhupha ividiyo kumbala we-8-bit, ngoko i-HDR VOB ingabonakalisa i-MKV.
