VOB ku BMP Mafunso Ofunsidwa Kawirikawiri Okhudza Kusintha kwa Anthu

Kodi ndingagwiritse ntchito ma frame amodzi kuchokera ku VOB ngati BMP zithunzi?

Kutsitsa fayilo ya VOB ndi wosinthira amatulutsa chisankho cha frame-extraction: chilichonse cha Nth frame, ma frame panthawi yofunikira, kapena chiwonetsero chimodzi pasecond.Katundu uliwonse wosankhidwa umasunthidwa kuchokera ku VOB video stream, amasinthidwa kukhala fayilo ya BMP yosiyana, ndipo imaphatikizidwa ngati ZIP yotsitsa. VOB ndi Video Object wonyamula anapeza mu VIDEO_TS wapamwamba wa aliyense DVD - MPEG-2 pulogalamu mtsinje ndi DVD-osiyana kuyendera deta anawonjezera. BMP ndi Windows Bitmap, raw raster mtundu anamanga mu Windows kuyambira 1985.

N’chifukwa chiyani ma frame anga ochokera m’mabuku ali ndi ma liwiro ozungulira omwe amapita mwa iwo?

Chifukwa cha zomwe zimachokera. VOB zomwe zili ndi zofalitsa ndi DVD zimasunga madera awiri apakati pa chipinda, zomwe zimatha kuwonetsedwa ndi chikwi chachiwiri, ndipo chosatha chosatha chikuwonetsa kuti chimapangidwa mogwirizana ndi chosatha pa chilichonse chomwe chikuyenda. Kukhazikitsa deinterlacing pambuyo potulutsa ndi chilichonse chosatha chimapangidwa kuchokera ku chipinda chokha chosatha chosatha.

Kodi ma subtitle adzawonekera pa BMP ma frame omwe ndimatulutsa?

Sikuti ngati ndi mndandanda wa subtitle wachikhalidwe. A VOB amasunga ma subtitle monga ma stream awo okha ndipo wosewera amawapanga pazithunzi nthawi yosewera, kotero decoded frame yomwe wosintha amalemba ngati BMP ili ndi pixels oyera pansi. Ma subtitle omwe adasungunuka mu kanemayo asanakhale VOB ndi nkhani ina - pomwepo ndi gawo la chithunzicho ndipo chilichonse chopangidwa ndi frame chimasunga iwo.

Kodi ndingatenge imodzi mwa BMP kuchokera ku gawo lililonse la VOB?

Si monga batani limodzi, koma VOB imapangitsa kuti zikhale zosavuta: masamba omarkidwa amasungidwa m'mabokosi monga nthawi yotchedwa, choncho werengani mndandanda wa masamba kuchokera pa fayilo ndi kuika nthawiyo m'malo a nthawi yolemba. Mumapeza BMP imodzi patsamba, m'njira, yomwe ndi njira yodziwika bwino yopanga mathumbnail kwa kujambula kotalika. Mafuta opanda masamba omarkidwa akukupangitsani kusankha mafilimu ndi maso. VOB amateteza zonse DVD payload - multiple angles, multiple audio zinenero ndi subtitle nyimbo zonse kupulumuka m'nyumba yake.

Kodi ndi chiyani chofunikira pa BMP mafayilo?

Kukula kwakukulu kuposa momwe mungayembekezere, chifukwa BMP imasunga ma pixel onse moyenera kuposa kuyerekezera. 1080p imakhalabe pafupi ndi 2-5 MB ndipo 4K imakhalabe pafupi ndi 6-15 MB, kotero kutulutsa kwanthawi yayitali kumawonjezera mwachangu. Izi ndi malonda abwino pamene zithunzi zimatha kutulutsa kuwongolera, ndipo zoyipa pamene zikuyenda mozungulira patsamba la webusaiti. BMP nthawi zambiri amasunga zonse uncompressed pixel mzere ndi ochepa header, chifukwa chake ndi kovuta kwambiri kufotokoza.

Kodi ndi yankho liti lomwe limatuluka BMP zithunzi zosadziwika?

Kuwala kofanana ndi choyamba VOB: 1080p VOB kumabweretsa 1920x1080 BMP ma frame, 4K VOB kumabweretsa 3840x2160 BMP ma frame. Wosinthayo sasintha kapena kuchepetsa - ma pixels amachokera pa frame yosinthidwa. Musanagwiritse ntchito /resize-image/ ngati mukufuna zithunzi zochepa.

Kodi ndingagwiritse ntchito chilichonse cha VOB ngati BMP?

Ndino, koma ganizirani kuchuluka kwa fayilo - 30 fps 1-mphindi VOB imapanga 1,800 BMP mafremu. Timawapaka m'chigawo chimodzi cha ZIP mwamsanga. Kwa mavidiyo ochepa, yesani "1 pa mphindi" (60 mafremu pa mphindi) kapena kusankha nthawi yoyenera. Ora la VOB pa mafremu onse lidzapanga ~100,000 BMP zithunzi.

Kodi BMP ma frame adzasunga VOB kujambula kwa mtundu?

Ndikoyenera - mtundu umasinthidwa ndi mapangidwe omwewo omwe amapezeka patsamba la VOB (BT.709 kwa HD, BT.2020 kwa 4K HDR). Mafuta a HDR amasinthidwa ku SDR pamene akugwiritsidwa ntchito ku BMP omwe sangathe kusungira ma pixel a HDR mwanjira yachibadwa (JPG, PNG-8).

Kodi ndi chiyani chosapanga dzimbiri chosapanga dzimbiri BMP pa diski?

Kutengera pa resolution ndi BMP codec kusankhidwa: 1080p PNG frame ndi 2-5 MB yopanda kusowa, 1080p JPG pa 85 quality ndi 200-500 KB. Kuwonjezeka kwa mitengo ya frame kuti muchepetse ZIP - pamapeto pake, kutulutsa kwa PNG kwa 10-1080p VOB kwa 10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-10-1

Kodi BMP yosakira imasunga metadata ya EXIF ya kamera?

VOB chonyamula sichimangokhala ndi EXIF pa frame momwe kamera ikugwirira ntchito, kotero mafayilo a BMP amatuluka ndi ma blocks EXIF opanda pake. Wosintha amagwiritsa ntchito `creation_time` field yomwe imasonyeza nthawi yoyambira ya frame, kuti muthe kubwezeretsa bundle m'njira yoyenera kapena kugwirizana ndi masamba a subtitle / chapter.

Kodi nthawi yayitali bwanji kuti mutenge chiwonetsero cha VOB mpaka BMP?

Kusintha kwa frame ndi kosavuta - nthawi zambiri 20-30% ya nthawi yochokera. 5-mphindi VOB -> BMP bundle imatha m'miphindi 1 popanda kutengera kuti ndi mapazi angati omwe mumasankha, chifukwa chingwe ndi BMP encoder kulemba mafayilo ambiri ochepa mofanana, osati VOB demuxer.

Kodi ndingagwiritse ntchito ma frame panthawi yoyenera m'mavidiyo a VOB?

Ndiyo — njira yowonjezera ya timestamp imavomereza mndandanda wogawidwa ndi koma (mwachitsanzo `00:01:23, 00:05:00, 00:10:42.5`) ndipo imapanga fayilo imodzi BMP pa timestamp. Ndikothandiza kwa thumbnails ya chapter, zithunzi zokhudzana ndi scene, kapena kulenga bokosi la mauthenga kuti lifufutidwe.
