VOB Isiguquli

Guqula VOB kuya futhi kusuka kumafomethi ahlukahlukene

Mayelana VOB

I-VOB (Into Yevidiyo) ifomethi yesiqukathi esetshenziselwa ividiyo ye-DVD. Ingaqukatha ividiyo, okulalelwayo, imibhalo engezansi, namamenyu okudlalwa kweDVD.

VOB Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini ihele VOB?

VOB (Video Object) is the container format for DVD-Video media.

Yini i-MPEG program stream, nokuthi kungani ifayela lami liyi-one?

I-multiplex eyenziwe ukuba i-decode yi-hardware esebenza ngokuqinile ngesikhathi sangempela, ayikwazi ukuhlela kwikhompyutha. Ama-packets omsindo nevidiyo axhunywe nge-time markers ukuze ibhokisi eliset-top likwazi ukuqala ukudlala kusuka kuwo wonke ama-stream, ngaphandle kwe-index futhi ngaphandle kokucindezela ihele lonke. Lo mkhiqizo uyini isizathu sokuthi VOB iqukethe ukudlala ku-hardware edala ngokugcwele futhi ikhohlisa ama-software amanje ngokuvamile. 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.

Kungani konke okuvela kwidiski kuphuma njenge VOB?

Ngenxa yokuthi ifomu lediski lichaza lokhu. Ividiyo, umsindo kanye nokuzulazula ku-optical disk kwabekwa ngokujwayelekile ngale ngxenyekazi efanele ukuze umdlali osebenza kahle oqinile angayifaka ngaphandle kwesoftware. Noma yini ekhishwa ku-disk ngakho ifika kuyo, igcwele ngemigomo yesikhathi — ukuxhuma, amaphesenti anzima wobukhulu kanye nokuhlukaniswa kwefayela kufakwe. VOB yividiyo equkethwe okutholakalayo kwifolda VIDEO_TS ngayinye ye-DVD — i-MPEG-2 izinhlelo ezihambayo ne-DVD-ekhethekile yokubuka idatha engeziwe.

Kungani isiphequluli sami singadlala ihele VOB?

Amabhuleki athumela ama-decoders kuluhlu oluncane lwefomethi, futhi VOB ayikho kulo — ilayisense, i-codec ehlukene evumela, noma nje ubudala bayo bugcina bungaphandle. Ihele alilahlekile futhi umdlali wedesktop uzovula, kodwa akukho okwenziwayo kukhasi kuzokwenza ibhuleki liyibonise. Ukushintsha ukuguqula kube nendawo yokugcinwa ye-web-native kuyindlela ethembekile kuphela yokudlala ngaphakathi. VOB ihlukaniswe phakathi kwefayela, ingase ibe CSS-encrypted, futhi ithwale ukuzula iphakethe elikhohlisa abadlali abadingayo.

Kungani ama-VOB am ashicilelwe ahlukaniswa ngama-parts amanani?

I-format-level ceiling, hhayi iphutha ku-recorder. VOB ine-file-single-limit esebenzayo esebenza kahle ehamba phambili noma i-bitrate-high material, ngakho-ke isofthiwe yokuqapha ihlukanise ukurekhodwa ngaphezu kokuletha ihele alikwaziyo ukulibonisa. Ukudlulisa ku-container ngaphandle komkhawulo onjalo kwenza ama-pieces aphinde axhunywe kuvidiyo eyodwa eqhubekayo, okuvame ukuba yisizathu esingokoqobo abantu abaguqula le-format.

Ingabe VOB izodlala kufoni noma TV ngaphandle kokushaya ibhayisikili?

Ngokuvamile, yebo, ngoba ama-chips efonini, ama-tablets nama-televisions afaka ikhophi le-payload e-silicon ekhethekile, hhayi kwi-processor eyinhloko. Lokhu kuyinto ehlukile phakathi kwevidiyo edlala i-cool ngehora elilodwa nelinye elifaka i-heat device futhi liyihlanze imizuzu emashumi amane. lapho ifomu lihla khona, i-app ixhasa i-app, hhayi uku-decode — i-codec iyilungile, i-wrapper yilokho i-gallery app ingakanani.

Ingabe kufanele ngigcine amafayela amasha njenge VOB?

Uma nje kukhona okuthile okudingayo. Ifomethi ivuliwe, futhi akukho sidingo sokushintsha ingobo yomlando ongeke ukwenze kube nzima, kodwa akuyona indawo lapho ithuluzi noma umphumela uhamba khona. Kunoma yini entsha, ifomethi yamanje ayidingi lutho olungeziwe futhi ivimbela ukulandelana kwesifundo seminyaka emincane kusukela manje.

Ingabe izihloko ezingezansi ngaphakathi kwe VOB zingakhethwa, noma ziboshwe ngaphakathi kwesithombe?

Kukhethwa, uma kufakwe kahle. VOB ifaka izihloko ezingezansi njengemithombo yabo ehlukile engezansi kwevidiyo, ngakho-ke umbukeli angashintsha ulwimi, azicishe, noma aphinde aphinde asebenzise izihloko ezingezansi kumdlali oxhasa lokhu. Izihloko ezingezansi ezibomvu zingasetshenziswa — ziyi-pixels kuphela kwifreyimu — kodwa zihlala njalo, futhi akuyona isizathu sokukhetha uma isiqulatho sixhasa into engokoqobo.

Ingabe VOB igcina izibonisi zesigaba?

Ikwenza — amasigaba ahlala kwi-metadata yebhokisi, ngakho ukurekhodwa okude kungafinyelelwa ngengxenye endaweni yokudonsa ibha yokuqhubekela phambili. Baphila ngokucindezela kabusha kufomethi ehlukile yesigaba esizizwayo futhi bakhuphuka, ngokuzizwayo, ngenye engakholeki. Uma amasigaba abalulekile, lokhu kufanelekile ukubheka ngaphambi kokukhetha ifomethi yesingeniso endaweni yokuqhubeka.

Ingabe ukusebenzisa VOB kuthatha ilayisense lepatenti?

Akunakho okukudingayo. Ama-codecs ahlobene ahlobene ne-patent pools, futhi ilayisense ibekwe ngabantu abathumela ama-decoders - ifoni, i-browser, i-operating system - isikhathi eside ngaphambi kokuba ihele lifike kuwe. Lokhu kusho ukuthi ifomu likhona kuwo wonke amahardware futhi kungani ama-royalty-free alternatives akhona, futhi ashintshanga noma yini mayelana nokushintsha ifayela oline.

Ingabe ngingenza ngiphinde ngibize isiqephu endaweni yokushintsha VOB?

Kunzima kakhulu, futhi kufanelekile ukuqonda ukuthi kungani: isithonjana siyisihloko, ngenkathi ama-bytes ngaphakathi kufakwe ngefomethi eyodwa ekhethekile. Ukushintsha igama kwenza ihele igama lakhe lithembisa okuthile okuqukethwe kwayo akusho ukunikela, futhi noma yini evula ihele noma liyiphoqa noma liyifunda kabi. Ukuphela kwephutha elincane yifomethi ezimbili ezikhona ngokusemthethweni ibhokisi elifanayo ngaphansi kwezinhlamvu ezahlukene — futhi ngisho lapho ukuphinda ubhale kahle kuphephile kunalokho ukushintsha igama.

Yini ezoba nehele lami VOB ngemuva kokuguqulwa?

Isuswa ngokuzenzakalela. Ukufaka kanye nemiphumela eguqulwe ihlala kumaseva ethu cishe amahora angama-24, oshiya isikhathi sokulanda imiphumela, bese isuswa ngokuzenzakalela. Ukudluliswa kuhamba nge-HTTPS emigwaqweni emibini. Akukho muntu ofunda okuqukethwe, akukho okuhlobene, futhi akukho okudluliswa kunoma ubani.
