Qaphela izitatimende zeCisco mayelana nomthombo ovulekile h264.

Iqonde ngqo emazwini kaRowan Trollope (IPhini Likamongameli Ophakeme weCisco kanye neMenenja Jikelele)

Uma kukhulunywa ngokudala ubuchwepheshe bokusebenzisana njengevidiyo evulekile futhi etholakala kabanzi evulekile, kuyacaca ukuthi isiphequluli sewebhu sidlala indima ebalulekile. Umbuzo uwukuthi, uyenza kanjani ukuthi isebenze ividiyo ebukhoma ngokuzalwa kuwebhu? Umbuzo abantu abalangazelela impendulo.

I-WebRTC - isethi yezithuthukisi ku-HTML5 - izophendula lowo mbuzo. Kepha, kunesithiyo esikhulu okufanele sidluliswe, futhi lokho kungukubekwa emthethweni kwekhodi evamile yevidiyo yokuxhumana kwesikhathi sangempela kwiWebhu - into i-Internet Engineering Task Force (IETF) ezonquma ngayo ngesonto elizayo.

Imboni yahlukaniswa kukhethwa ikhodekhi ejwayelekile yevidiyo okwesikhashana, ngoba indinganiso yezimboni - u-H.264 - idinga ukukhokhwa kwemali yobukhosi ku-MPEG LA. Namuhla, ngijabule ukumemezela ukuthi iCisco ithatha isinyathelo ngesibindi sokususa ukukhathazeka ngokukhokha etafuleni.

Sihlela ukuvula ikhodi ye-H.264 codec yethu, futhi siyinikeze njengemodyuli kanambambili engalandwa mahhala kwi-inthanethi. I-Cisco ngeke ishiye izindleko zethu zelayisense le-MPEG LA zale mojuli, futhi ngokuya ngemvelo yamalayisense yamanje, ezokwenza ukuthi i-H.264 ikhululeke ukuyisebenzisa ku-WebRTC.

Kuyangijabulisa futhi lokho IMozilla izomemezela ukuthi izokwenza iFirefox isebenzise le module, enikeza ukusekelwa kwesiphequluli sangempela se-H.264.

"Bekungelula, kepha iMozilla isize ukuqondisa umkhakha ukuthi ubheke ividiyo engasebenziseka kuwebhu," kusho uBrendan Eich, oyiMozilla CTO. “Isimemezelo seCisco sisisiza ukuthi sisekele i-H.264 kuFirefox ezinhlelweni eziningi zokusebenza, nasezansi nakweminye imithombo evulekile yomthombo kusetshenziswa imodyuli kanambambili yeCisco H264. Kuyasithokozisa ukusebenzisana neCisco ukuthuthukisa isimo sevidiyo esisebenzisanayo. "

Futhi kungani ngithi qaphela? Phinda ufunde isigaba ngokugqamile. Ngenkathi bezokhipha ukuqaliswa kwabo kwe-h264 (ngaphansi kwelayisense BSD, bathi), kunjalo the kanambambili eyenziwe yi-cisco leyo ezosetshenziswa mahhala yiwo wonke umuntu, naleyo iMozilla ezoyisebenzisa ukuxhasa iFirefox (basanda kumemezela ukuthi bazoyisekela nge-gstreamer, manje yiCisco ebanika isandla). Kuzoba yiCisco ezokhokha i-MPEG LA imali ekhokhwa njengamanje (futhi kuze kube ngu-2015) $ 6,5 million minyaka yonke ukusetshenziswa kwe-h264 (iMozilla ayicabangi ngisho nokuyikhokha, yingakho isikhathi eside benqabile ukuxhasa). Kepha, uma kwenzeka kuwe ukufinyelela ikhodi yomthombo, uyilayishe, uyishintshe, uyihlanganise futhi uyihambise (mahhala noma cha), inhlanhla inqwaba ukuqoqa imali eningi ukukhokha amaroyali (ngaphandle uma izwe lakho lingawazi amalungelo obunikazi besoftware, kuleso simo iViva la Pepa).

Uma kukhona kini ocabanga nge-x264, ngiyakutshela ukuthi yize i-x264 imahhala, akunjalo kusukela lapho futhi kuyisihloko kuya kumalungelo obunikazi angu-h264. Ngamanye amagama, umehluko phakathi kwe-x264 nokusetshenziswa kweCisco yilayisense (GPL vs BSD). Ngakho-ke khumbula, kuyinto eyodwa ukukhipha inkululeko nenye into lokho akunamalungelo obunikazi.

Kukhona nezinye izinto okufanele uzicabangele futhi. Okokuqala, lesi yisinyathelo sokuqhubeka nokuncintisana ne-VP8 yakwaGoogle (I-Google ayisithandanga isikhangiso). Okwesibili, ama-h265 nama-VP9 codecs wamavidiyo wencazelo ephezulu eza maduze, futhi iMozilla ngeke iwashaye indiva amanye ama-codec avulekile, kufaka phakathi Daala (i-codec abayidala ndawonye ne-Xiph, abasunguli befomethi ye-OGG nama-Vorbis codecs, iTheora ne-Flac), ethembisa ikhwalithi engcono kune-h265 ne-VP9 futhi ingenawo amalungelo obunikazi.

Ukuqeda ngikushiya okukhombisa iMonty Montgomery (kusuka kuXiph) okusho konke:

Ukulungiswa kwanamuhla kuyisiqeshana, futhi akuguquki kakhulu ngemuva. Bangaki abantu abangenayo ama-codec angama-H.264 emishinini yabo, ngokusemthethweni noma cha? Abathanda futhi ochwepheshe ngokufanayo abanaki kangako amalayisense. Ngisho namabhizinisi amaningi namuhla awazi noma akanandaba ukuthi ama-codec awasebenzisayo anamalayisense afanele (ngokusho kwe-MPEG LA, kunamalayisense ayi-1276 emhlabeni). Yonke imakethe ye-codec ibisebenza ngaphansi kwenqubomgomo ethi 'Ungabuzi, ungasho' kule minyaka eyi-15 edlule futhi ngiyangabaza ukuthi i-MPEG LA iyakhathala. Lokho kusize ekwenzeni i-H.264 ikuyo yonke indawo, futhi i-MPEG LA ingaqhubeka nokuphoqa izithupha zelayisense uma kuyinzuzo yazo yokuncintisana (noma kunalokho, inzuzo yabo yokulwa nokuncintisana; bayinkosi evikelwe ngokusemthethweni ngemuva kwakho konke. ).

Ah, enye into. Lapha ngikunikeza imininingwane mayelana namalungelo obunikazi we-MPEG. Maduzane, amalungelo obunikazi e-MP2017 azophelelwa yisikhathi ngo-3, MPEG-2018 (h2) ngo-262 no-h2028 kuphela ngo-264.

  1.   nano kusho

    Futhi kangangoba sidinga ukubona iwebhu yeqiniso ngokususelwa kumazinga wamahhala.

    Akukho kulokhu okulula okuyiqiniso

  2.   masisebenzise i-linux kusho

    Kuyathakazelisa ... asethembe ukuthi ngolunye usuku sizobona enye indlela yamahhala yokudlala amavidiyo ku-inthanethi.

    info xD ethokozisayo yize lokhu okugcina kungacaci kimi ukuthi ukuphela kwe-mp3? Usho ukuthini?

    1.    phumlani kusho

      kumalungelo obunikazi avikela ifomethi ye-mp3

      1.    Makubex Uchiha kusho

        Kodwa kuzokwenzekani lapho befika? ungaqhubeka nokudlala i-mp3?

        1.    phumlani kusho

          Vele, futhi ngokukhululekile.

          Kwenzeke into efanayo nangefomethi ye-GIF amalungelo ayo obunikazi aphelelwa isikhathi ngo-2003. Manje isiyifomethi engenamalungelo obunikazi.

  4.   Staff kusho

    Ngiyaphinda lokho engikuphawula ku-linux kakhulu.

    AbakwaCisco balungiselela ukukhokha irenti yaminyaka yonke yamaRandi ayizigidi ezingama-6.5, ukuze basabalalise ikhodekhi eselizothuthwa futhi esevele isetshenzisiwe kwiziphequluli ezinjengeFirefox (ehamba ngefulegi lamahhala nelimisiwe) kusukela ngaphambi kokuba lokhu kwaziwe. (Noma mhlawumbe iMozilla ibivele isazi).
    Akunakwenzeka ukuthi ungabukeki usolisa.

  5.   UMarcelo martinez kusho

    Kufanele sizame ukulinganisa i-WEBM (vp8 + vorbis)
    Okungaba nengcindezi yokuthi lokhu kwenzeke ukuthi amawebhusayithi lapho kulayishwa ukulayishwa kwama-movie nomculo ukuze asebenzise ama-codec wamahhala esikhundleni sama-proprietary.

  6.   nguSebha kusho

    Lapho ngifunda lezi zindaba ngesonto eledlule, angiqondanga ukuthi kungani kwathiwa "kumahhala" uma ekugcineni ingekho yonke inkululeko ephakanyiswa yi-RM.

    Kuhlala nje kunethemba lokuthi iDaala iphumelele kangcono kuneWebM.

    Ngingathanda ukuthola impendulo. Ngangifakwe ku-mozilla firefox ukugcwalisa i-plugin
    I-OpenH264 Video Codec inikezwe yiCisco Systems, Inc.

    Ngifuna uma unomusa ongangitshela ukuthi ngabe lokhu kunezindleko kimi noma ngabe kumahhala, ngiyabonga
