Kodi ndi DivX kanema wapamwamba?

DivX ndi video codec kuposa chonyamula - amafotokoza mmene aliyense frame ndi encoded. DivX ndi nthawi zambiri anapaka m'matumba m'nyumba ya chonyamula monga MP4 kapena MKV pamene anasunga pa diski.
Kodi DivX ndi codec kapena mtundu wa fayilo?

Codec, chifukwa chake yankho la "mwanji ndizitsegule" siliyenera kukhala lokha. DivX limafotokoza mmene chithunzi chimasinthidwa; silimanena chilichonse za momwe bitstream ikugwiritsidwa ntchito pa diski, ndipo iyenera kukhala ndi chonyamula m'malo mwake kuti wosewerayo ayambe kuika. Fayilo yotchedwa DivX m'maphunziro ndi bitstream m'matumba ena oyera, ndipo kusintha kumatanthauza kusintha matumba, codec, kapena onse awiri. DivX amatchedwa codec kuposa chonyamula - MPEG-4 Part 2 kukwaniritsa kuti anachita ripping DVD kuti CD imodzi zotheka m'zaka za m'ma 1999.
Chifukwa chake ali ndi zonse zokhudzana ndi diski popanda kuwononga chilichonse cha izo - chilichonse cha mawu, chilichonse cha subtitle, mnda wazaka - mu fayilo imodzi. Izi ndi zosasinthika zoyenera pamene cholinga ndi kuika uthenga wa oyambirira, ndipo zosayenera pamene fayilo iyenera kusewera pa chipangizo chomwe chimamvetsa mtundu wotumizira. DivX-certified DVD osewera ndibe otchuka, ndipo codec ali ndi kugwirizana pansi kwa wonse chiyambi cha set-top hardware.
Nchifukwa chiyani msakatuli wanga sadzasewera fayilo ya DivX?

Mawebusayiti amatumiza decoders kwa mndandanda wocheperako wa mafomu, ndipo DivX siyipatsidwa - lisensi, mtundu wa codec womwe umalola, kapena nthawi yake imatenga. Fayilo siyimawonongeka ndipo wosewera wa desktop adzatsegula, koma palibe chomwe mungachite patsambalo kuti mupange msakatuli. Kusintha kwa webusaitiyi ndi njira yokha yotsimikizika yosewera. DivX amafuna pafupifupi katatu bitrate wa H.264 kwa mtundu wofanana ndi palibe njira kwa HDR, 10-bit mtundu kapena resolutions m'munsi 1080p.
Nchifukwa chiyani mavidiyo anga a DivX amasonyeza makompyuta a comb pa chilichonse chomwe chimayenda?

Chifukwa chake ndi interlaced. Zolemba mu mtunduwu nthawi zambiri zimachokera ku broadcast ndi DVD era, komwe chilichonse chimasunga ngati madera awiri a half-height omwe amatenga gawo la 50 la theka la mphindi. Progressive screen ikuwonetsa zonse ziwiri pamodzi, kotero kuyendetsa pakati pa ma exposition awiri amawoneka ngati kukongoletsa kwa horizontal. Deinterlacing pa kusintha kumapanga madera kukhala ma frame onse ndipo artefact imatha kutuluka bwinobwino.
Kutalika kwa mtundu wamtundu, si vuto la wolemba. DivX ili ndi malire ogwira ntchito a fayilo imodzi yomwe imayenda mozungulira kapena yotsika mtengo, kotero pulogalamu yojambula imagawa kujambula komwe kumatha kutulutsa fayilo yomwe siyingathe kuindex. Kusintha kwa kontena popanda malire amatilola kuti tigwirizanenso ndi kanema wopitilira, zomwe nthawi zambiri ndizofunikira kwambiri kuti anthu azisintha mtunduwu.
Nchifukwa chiyani DivX kusewera kumathamanga kapena kutuluka pa makina oyambirira?
+
Chifukwa chake chimasinthidwa mu software. Ma decoders a hardware video amaphatikizapo mndandanda wokhazikika wa mafomu, ndipo DivX ndi kunja kwa izi pazinthu zambiri, kotero kuti chilichonse chimapangidwanso ndi CPU. Pa desktop yatsopano yomwe ndi yowononga; pafoni, laptop yakale kapena smart TV imawonekera ngati ma frame osunthira, mpweya wa fan ndi batri. Kusintha kwa mtundu wothandizidwa ndi hardware kumachotsa vuto lonse. DivX zinthu ndi MPEG-4 Part 2 kanema, nthawi zambiri anapaka mu AVI, ndi MP3 kapena AC-3 audio mbali yake.
