VOB kuya FLV Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani i-VOB ku-FLV ngaphandle kokulahlekelwa yikhwalithi yevidiyo?

Layisha phezulu ihele lakho VOB futhi umguquli uqhuba i-CRF-based re-encode ebhekisa ku-visually-lossless FLV output (CRF 18 ngokuzenzakalela, amaxabiso aphansi = ifayela elikhulu / ubunjani obuphezulu). I-codec ikhethiwe ukufana ne FLV container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines. I-VOB iqukethe i-MPEG-2 video, AC-3 noma umsindo we-PCM, kanye ne-DVD subpicture subtitle streams, ihlukaniswe ibe yi-1 GB segments yi-DVD spec. I-FLV ivame ukuphatha i-Sorrenson Spark noma i-H.264 video ne-MP3 noma i-AAC audio, efakwe kufomethi yokuhamba eyenziwe nge-RTMP delivery.

I-VOB yami ibonisa ama-comb lines ekuhambeni - ngabe lokhu kuzodluliselwa ku-FLV?

Kuzokwenzeka uma ungasebenzisi i-deinterlace, futhi VOB okuqukethwe kuvame ukuxhunywa ngoba ifomu livela esikhathi sokusabalalisa ne-DVD. Amafreyimu axhunywe agcina ama-fields amabili aphakathi nendawo aphezulu athathwe ngengxenye yesihlanu yesibili; kufoni noma kumboniso oqhubekayo-oqhubekayo ofunda njenge-horizontal combing nganoma yini ehambayo. Vula ukhetho lokuxhunyaniswa futhi umbhalo-mqoka uxhuma ama-fields kuwo wonke ama-frames aqhubekayo ngaphambi kokubhala i-FLV. VOB yividiyo equkethwe okutholakalayo kwifolda VIDEO_TS ngayinye ye-DVD — i-MPEG-2 izinhlelo ezihambayo ne-DVD-ekhethekile yokubuka idatha engeziwe.

I-VOB yami yokurekhoda ihlukaniswe ibe yizingxenye ezinombhalo - i FLV inezinga elifanayo?

Hayi, futhi lokhu kuyisizathu esingcono sokushintsha. I VOB iqukethe i-file eyodwa esebenza kahle eyenza ukurekhodwa okude noma okuphezulu kwe-bitrate kuhambe ngokuqondile, okuyinto ebangela ukuthi ukurekhodwa okudala kufike njengengxenye1, ingxenye2, ingxenye3. FLV ayinaso isibopho esifanayo, ngakho ama-pieces angaxhunywa kabusha kwifayela elilodwa eliqhubekayo. VOB ihlukaniswe phakathi kwefayela, ingase ibe CSS-encrypted, futhi ithwale ukuzula iphakethe elikhohlisa abadlali abadingayo.

Yini ezoba nezinhlamvu zesihloko esingezansi kuhele lwami VOB?

Ngakhoni ukuhlala bekhethwa, ngoba FLV ayikho i-soft-subtitle stream egcina isihloko. Kunezindlela ezimbili zokuzikhipha: ukufaka kuvidiyo ngesikhathi sokuguqulwa, okuzozenza zihlala zihlala futhi zingashintshwa, noma ukuthumela ngaphandle njenge.srt ehlukile ecaleni le FLV ukuze umdlali alayishe. Umguquli utshela ukuthi yini eyayenza ngaphandle kokushiya isihloko ngokucophelela. Akukho isiphequluli, ifoni noma i-TV ekhona engakwazi ukudlala i-FLV — noma yini ekhona kule bhokisi kumele ihunyushwe ngaphandle ukuze ihlale ibonakale.

I VOB yami inezinhlamvu zomsindo eziningi — zingaba zonke zihlala ngaphakathi kwe FLV?

Akunakuthembeka. VOB igcina imisindo eminingi njengezingoma zohlobo lokuqala, kodwa FLV uxhaso lokudlala ngaphezu kwengoma yokuqala akulingani, ngakho abadlali abaningi bazoveza kuphela eyodwa. Khetha ingoma oyifunayo ngaphambi kokuguqula; abanye bakhishwa kahle kumafayela abo ngaphezu kokushiya emgodini ofihlayo. I-VOB igcina yonke i-DVD payload - ama-angles amaningi, izilimi eziningi zomsindo nama-subtitle tracks wonke ahlala ngaphakathi.

Kungani ihele lami VOB lingakwazi ukushintsha ku FLV?

Kuyinto evamile kakhulu i-DRM. Ezinye VOB izithombe zibhalwe ngokufihlakele ku-bitstream level yisitolo noma isofthiwe eyenza, futhi isithombe esibhalwe ngokufihlakele asikwazi ukucinywa yithu noma yinoma yini ngaphandle kwesitshixo selayisense. Izithombe ongazirekhodile, ozenzayo noma ozibhumele ngaphandle azikhuselwanga ziguqulwa ngokuvamile; ukuthenga okusemthethweni akuzokwenza, futhi akukho oguqulelayo angaba nesiqiniseko sokuthi kungashintshwa.

Ingabe i-FLV izodlala ngokulula ku-smartphone noma ku-TV?

FLV ngokuvamile ibuyela emuva ku-software decoding ku-hardware efanayo - u-CPU ophezulu, isisetshenziswa esipholile, namafreyimu akhuphuka ku-4K material. Uhlelo oluzosetshenziswa, VOB luyi-container ephephile yokuhlala kuyo.

Yini i-codec yevidiyo i FLV isebenzisa?

Kuxhomekeka ku FLV isihlungi. MP4 iphutha ku-H.264 ukuze kuxhaswe ukusakazwa okubanzi phakathi kwamafoni, amabhurawuza, nama-Smart TVs.

Yebo. Uma VOB ne FLV zihlanganisa i-codec yomsindo (isibonelo, zombili zifaka i-AAC), umsindo uphinde uhlukaniswe ngaphandle kokuphindeka kokufaka ikhowudi — okufanayo. Uma ama-codecs ahlukile, umsindo uguqulwa ube yi-AAC / Opus / Vorbis ngokuya ngomsebenzi oxhaswa yi-FLV. Umsindo we-multi-track (umbono, izilimi ezihlukile) ugcinwa.

Ingabe ubukhulu behele bushintsha kanjani kusuka ku VOB kuya ku FLV?

Same-codec re-mux (VOB H.264 → FLV H.264 ushintsha isihlungi kuphela): ubukhulu obufana kakhulu. Ushintsho lwe-codec lungashintsha ngokujulile: H.264 → H.265 ngokuvamile uhlukanisa ihele ngengxenye ngekhwalithi efanayo yokubuka; VP9 ifana kakhulu; AV1 ihlukanisa ezinye i-20-30% kodwa ihamba kancane uku-encode.

I-WebM iyisiphequluli-kuqala. Izinketho ezithuthukisiwe zifaka phakathi "ukuxhumana kwedivayisi" okusetshenzisiwe okukhetha i-FLV codec / ibhokisi eliphephile lenjongo yakho. FLV's low per-packet overhead yenze it okungcono e streaming phezu ukuxhumana unreliable yesikhathi sayo, futhi amafayela amakhulu yayo akhona.
