Iyo itsva chirongwa che yakanyanya kushanda vhidhiyo kukodha mwero (HEVC nechidimbu chayo muChirungu), inozivikanwawo se H.265, inotarisirwa kuve inoshanda zvakanyanya kupfuura yakatangira, H.264 Yepamberi Vhidhiyo Coding. Zviri nani zvakadii mubvunzo wemamirioni emadhora. Zvichava a kunatsiridza zvakakwana kupembedza kuwanda kwemaindasitiri kutorwa kweichi chitsva chiyero? |
Inoshanda sei HEVC?
Bin Li, Gary Sullivan, naXu Jizheng vakaburitsa fananidzo yekuita pakati peH.264 / AVC neHEVC Working Draft 4 munaNovember 2011. Unogona kuwana iro rakazara gwaro nemhedzisiro pano:
Tafura 4 yechinyorwa ichi inofanidza kumanikidza kuita kweiyo HEVC Bvunzo Muenzaniso ("HM") uye iyo H.264 Bvunzo Muenzaniso ("JM"). Paavhareji, HEVC inopfuura H.264 ne39% yezviitiko zvisingawanzo kuwanikwa (kutepfenyura, semuenzaniso) uye ne44% yezviitiko zvakaderera-kunonoka (semuenzaniso, vhidhiyo mafoni).
Izvi zvinoreva kuti iyo HEVC codec inogona kuzadzisa iwo iwo akafanana hunhu seH.264 ine yekuponesa zvishoma chiyero chakatenderedza 39-44%.
HEVC ichiri mukusimudzira, uye isu tinogona kutarisira kuona kuwedzera kwekuita mune ramangwana shanduro dzeprojekti.
Kuguma kweWebm?
Google yakazivisa gore rapfuura kuti yabvisa rutsigiro rwe .H264 vhidhiyo muHTML5 kubva kune yayo Chrome browser. Iyo hofori yeInternet inoziva kukosha kweiyi yakakurumbira fomati yemavhidhiyo uye kuti yakaita chinzvimbo chakakosha mumakore achangopfuura, asi nekufamba uku inotarisira kumanikidza vashandisi kutora macodec ayo akavhurwa akagadzirwa neGoogle WebM pamwe naOgg Theora.
Google yanga ichishanda kwenguva yakareba pamafomati akasiana-siyana akagadzirwa nekambani imwechete iyo inotarisira kubvisa mamwe macodec uye mafomati ekuomesa mifananidzo, anodiwa pakufambisa data paInternet. Muna Gumiguru 2010 yakatanga WebP, imwe nzira yekumanikidza kuJPEG uye mwedzi mishoma yapfuura, muna Chivabvu 2010, WebM sevhidhiyo codec.
WebM inotsigirwa neMozilla, Opera, uye Adobe maringe neMicrosoft neApple, zviri kumashure kweH.264. Apple yanga ichitsigira nekusimudzira iyi codec kwenguva yakareba uye Microsoft ichangobva kuzivisa kuti Internet Explorer 9 ichaunza rutsigiro rwemuno kushanda neH.264 yakananga kubva kubhurawuza pasina kudikanwa kwepaki-inokosha, ingave yayo kana kubva kune yechitatu. mapato. Uye zvakare, rakakosha boka revagadziri vechip, vagadziri veesoftware kana vagadziri vepariperi senge AMD, ARM, Brightcove, Broadcom, Collabora, Dhijitari Rapids, Encoding.com, Grab Networks, iLinc, INLET, Kaltura, Logitech, MIPS, Nvidia, Ooyala , Qualcomm, Skype, Sorenson, Telestream, Texas Instruments, Verisilicon, ViewCast, uye Wildform inotsigira ichi chirongwa cheGoogle.
Google, pachikamu chayo, yanga ichishandura mavhidhiyo kune iyi fomati nyowani kwechinguva kuti ivasanganise mune yayo inozivikanwa YouTube vhidhiyo pasocial network uye mamwe acho atowanikwa, kunyange zvichidikanwa kuve nebrowser inoenderana nemhando yacho, iyo parizvino inogona kungova Bata shanduro dzekuvandudza dzeFirefox neOpera.
Nekudaro, zvinoita sekunge Webm haipedze kusimuka. Kutanga, kwete ese mavhidhiyo eYouTube akashandurwa. Kune rimwe divi, vashoma kwazvo maDVD kana maBlu-ray vatambi vanotsigira iyi fomati. Zvakare, pane zviripo zvidzidzo zvakati wandei zvinoratidza kuti Webm haina kuita zvakanaka ichienzaniswa neH.264. H.265 budiriro ichave kupera kweWebm here?
Kutanga kubva ini ndoda kutaura blog yakanaka! Ndakave nemubvunzo unokurumidza uyo
Ndinoda kubvunza kana iwe usinei nazvo. Ini ndaive neshungu yekuziva kuti unozvimisikidza sei uye kujekesa musoro wako usati wanyora. Ndanga ndine dambudziko rekubvisa pfungwa dzangu pakuburitsa pfungwa dzangu. Ini ndinofarira kunyora asi zvinoita sekunge maminetsi gumi kusvika gumi nemashanu anotanga kutambiswa uchingoyedza kufunga kuti wotanga sei. Chero mazano kana mazano? Zvikoshe!
Zvakare shanyira webhusaiti yangu ... simuka
Zviripachena kuti Google yakashaiwa chishuwo chekuita WebM yakajairwa kana kungoita sarudzo yakanaka yeH.264, zvinongoratidzika sekuti haisi chirongwa chakakosha zvikuru.
Nekuuya kweH.265 kuWebM zvichaitika zvakangofanana neLibreOffice neOpenOffice pasati pasvika Hofisi 2007 na2010, ivo vachangogara semasvosve akatarisa mudenga, apo makwikwi anotora nzira yavakaita.
Chokwadi ndechekuti H265 inovimbisa mhedzisiro inonakidza, semuenzaniso bhaisikopo rakazara mu1080p mhando inogona kukwana paCD. Chinhu chinokurumidzira kurodha pasi kwangu zvakanyanya 🙂
Nesere Mbps yekubatana, ndinofara kuti zvinotora nezve 8GB, asi WELL USED.
Maitiro andinozviona, WebM ine matambudziko makuru maviri:
* Chinonyanya kukosha ndechekuti, pamwero mumwe chete, WebM ine yakanyanya kunaka mhando kupfuura H264.
* Rimwe dambudziko nderekuti Google haina kubheja pakusimudza mhando yeWebM uye kupfuura H264, ichisiya yekupedzisira kuhwina mutambo.
Zvinonyadzisa zvikuru, asi Google haigone kutarisira kuti vanhu vashandise chimwe chinhu nekuda kwekuti Google inoirwira. Google ine nzira uye zviwanikwa zvekuita WebM kukwikwidza codec, uye zvakadaro haina. Mumwe aifanira kushamisika kuti sei.
Ndinovimba kuti webm hairegi, vp8 + opus inogona kukurudzira zvishoma asi haina kukwana kana iri muvhidhiyo, kana vasingakwanise kukunda H.264 neH.265 zvishoma asi kana vasingade codec yakavharwa kuti ienderere mberi nekudyara asi ini usawone Iwe Unohwina nhau dzekupedzisira dzandakaona pane yako blog yaive 1.1.0 (Eider) iyo inovimbisa kushomeka kushoma, hapana chakakura icho anime, kune rimwe divi, opus anovimbisa uye zvakanyanya sekuteerera codec inoridza mp3 muhunhu
