VOB ukuba FLV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani ikhowudi i VOB ibe yi FLV ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho VOB kwaye umguquli uqhuba i-CRF-esekelwe kwakhona-ukukopela ukujolisa kwi-visually-lossless FLV imveliso (CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne FLV isiqulathi seefayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 ye-newer pipelines. I-VOB igcina i-MPEG-2 video, AC-3 okanye i-PCM audio, kunye ne-DVD subpicture subtitle streams, ihlukaniswe ibe yi-1 GB yecandelo nge-DVD spec. I-FLV ihlala igcina i-Sorrenson Spark okanye i-H.264 video ene-MP3 okanye i-AAC yesandi, ejikelezwe kwifomati yokuhamba eyenziweyo yokuhambisa i-RTMP.

I-VOB yevidiyo yam ibonisa imigca ye-comb kwi-movement - iya kuthatha into kwi-FLV?

Iya kwenza ukuba awuyi-deinterlace, kwaye VOB imixholo ihlala i-interlaced ngenxa yokuba ifomati ivela kwixesha le-broadcast ne DVD. Iiframes ezi-interlaced zigcina iindawo ezimbini eziphakathi-ubukhulu eziqhotyoshelwe kwishumi elinesihlanu sesibini; kwifowuni eqhubekayo-yokukhangela okanye imboniselo efunda njenge-horizontal combing nantoni na ehambayo. Yenza ukhetho lwe-deinterlace kwaye i-encoder igubungela iindawo kwi-frames ezipheleleyo eziqhubekayo phambi kokubhala i FLV. 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.

I-VOB yam yokurekhoda ihlukaniswe ibe ziinxalenye ezilinganisayo - ngaba i-FLV inemida efanayo?

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. FLV ayinalo umda ofanayo, ngoko ke iinxalenye zinokudityaniswa kwakhona kwifayile enye eqhubekayo. I-VOB ihlukaniswe phakathi kweefayili, ingafihliwe nge-CSS, kwaye ihambisa iipakeji zokhangelo eziphazamisa abadlali abafunayo.

Yintoni eyenza i-subtitle tracks kwifayili yam VOB?

Ayikwazi ukuhlala ikhethiwe, kuba FLV ayinayo i-soft-subtitle stream ukubeka i-subtitles. Zikhona iindlela ezimbini zokuphuma: ukutshabalalisa kwividiyo ngexesha lokuguqula, okwenza ukuba zihlala zihlala kwaye zingatshintshwa, okanye urhweba ngaphandle njenge.srt eyahlukileyo ecaleni kwe FLV ukuze umdlali alayishe. Umguquli uthetha ukuba yintoni eyayenza kunokuba ikhuphe ngokucokisekileyo. Akukho mkhangeli zincwadi, ifowuni okanye iTV iya kudlala i-FLV - nantoni na esele ikwi-container kufuneka ishenxiswe ngaphandle ukuze ihlale ibonakale.

I VOB yam inezinto ezininzi ezidlala umculo - ngaba zonke ziya kuhlala zikhona kwi FLV?

Ayithembekanga. VOB igcina imijelo emininzi yesandi njengemizila yohlobo lokuqala, kodwa FLV uxhaso lokudlala ngaphezulu kwemizila yokuqala ayihambelani, ngoko abadlali abaninzi baya kutyhila kuphela enye. Khetha imizila oyifunayo phambi kokuguqula; abanye bangcono ukutywina kwifayile zabo ezikhethekileyo kunokuba bashiye kwisiqulathi seefayili esifihlayo. I-VOB igcina yonke i-DVD yothutho olusebenzayo - ii-angles ezininzi, iilwimi ezininzi zesandi kunye nengoma yomxholo ophantsi zonke zihlala ngaphakathi.

Ingaba i FLV iyaqhubeka idlala ngokulula kwifowuni okanye kwiTV?

Ingaba ayikwazi. VOB ikhowudiwe yisilicon ekhethekileyo kwifowuni, iitablethi kunye neeTV, nto leyo eyenza ukuba idlala ngaphandle kokutyibilika kwebhetri. FLV 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.

Yeyiphi i-codec yevidiyo esetyenziswa yi-FLV yemveliso?

Ixhomekeke kwi FLV isiqulathi seefayili. I-MP4 imiselwe ukuba i-H.264 ukuze ixhase ukudlala okubanzi phakathi kweefowuni, iibrowser, kunye neSmart TVs. I-MKV imiselwe ukuba i-H.265 / HEVC ukuze ijikeleze i-half of the file size at equivalent quality. I-WebM imiselwe ukuba i-VP9. Iinketho eziphambili zibonisa ukhetho olucacileyo lwe-codec ukuba ufuna ukucima. FLV yindawo yokugcina i-Flash Video ehambisa yonke i-web video ukusuka ngo-2003 de i-Flash ivale ekupheleni konyaka ka-2020.

Ingaba umculo wam wesandi uya kuqhubeka uguquka VOB ukuya FLV?

Yes. When VOB and FLV share an audio codec (e.g. both carry AAC), audio is re-muxed with no re-encode — bit-identical. When the codecs differ, audio is transcoded to AAC / Opus / Vorbis depending on what the FLV container supports. Multi-track audio (commentary, alternate languages) is preserved.

Ndingagcina i-framerate yokuqala xa ndiguqula i-VOB iye kwi-FLV?

Ngokungagqibekanga ewe — i-24fps VOB ihlala i-24fps kwi-FLV; i-60fps VOB ihlala i-60fps. Ukuba ufuna ukuguqula umyinge (umzekelo, i-interlaced 29.97 → i-progressive 30, okanye i-60 → 30 yokukhuphela umda), ukhetho lobungakanani be-frame luphatha 3:2 ukutsala ezantsi, ukususa uthungelwano, kunye nokuqhekeka kwe-frame kwindlela efanayo yokukopela.

Ingaba ubungakanani befayili butshintsha njani ukusuka kwi VOB ukuya kwi FLV?

I-codec efanayo yoku-mux (VOB H.264 → FLV H.264 itshintsha kuphela isiqulathi seefayili): ubungakanani obufanayo. Utshintsho lwe-codec lunokutshintsha ngokumangalisayo: H.264 → H.265 luya kuquka ifayile kwinqanaba elifanayo lomgangatho obonakalayo; VP9 imalunga nokuthelekiswa; AV1 iquka enye i-20-30% kodwa ihamba phantsi ukukopela.

Ingaba ifayili FLV iyadlala kwi-iPhone, Android, kunye neSmart TVs?

MP4 / H.264 idlala ngokusemthethweni kwisixhobo ngasinye esitsha. MOV / H.264 idlala kwizixhobo zeApple kunye neTV ezininzi kodwa hayi rhoqo kwi-Android edala. MKV ifuna i-VLC kwi-iOS. WebM ikwi-browser-first. Iinketho eziphambili ziquka "ukulungelelanisa isixhobo" esimiselweyo esikhetha i-FLV codec / isiqulathi seefayili esikhuselekileyo so target yakho. I-FLV's ephantsi ngepakethi nganye i-overhead iyenze igqibelele kwi-streaming ngaphezulu konxibelelwano olungathembekiyo lwexesha lakhe, kwaye ii-archives ezinkulu zayo zihlala zikhona.

Ithatha ixesha elingakanani ukutshintsha i-VOB yevidiyo yeyure enye ibe yi FLV?

I-Same-codec re-mux ikwindawo efutshane-imizuzu engama-30 ukuya kwengama-60 yefayili yeyure enye. I-codec epheleleyo iqhuba ngokuthe ngqo kwi-0.3-0.7x yobude bomthombo kwi-GPU yethu, ngoko ke i-1-hour VOB → FLV igqiba kwimizuzu engama-18-40 ngokuxhomekeka kwisisombululo kunye ne-codec emiselweyo.

VOB

I-VOB (i-Video Object) yifomati yesikhongozeli esetyenziselwa ividiyo yeDVD. Ingaqulatha ividiyo, iaudio, izihlokwana, kunye neemenyu zokudlala kweDVD.

FLV

I-FLV (iVidiyo yeFlash) yifomati yesikhongozeli sevidiyo ephuhliswe nguAdobe. Isetyenziswa ngokuqhelekileyo ukusasazwa kwevidiyo kwi-intanethi kwaye ixhaswa yi-Adobe Flash Player.
