I-Big Sevastopol Officers' Ball ngokwesiko yenzeka ngoJuni, kodwa kulokhu amalungiselelo awahambanga kahle. Abahleli banquma ukwethula "Sevastopol Ball Online". Njengoba sekuphele iminyaka ilandelana sisakaza lo mcimbi, bekungasekho lapho ngingahlehla khona. Ababukeli kuFacebook, VKontakte nakuYouTube, izithandani ezingu-35 zidansa ekhaya.
Sekukonke, njengoba sibambe iqhaza ekusakazweni kwe-inthanethi isikhathi eside, sabona inkambiso cishe yonke iphrojekthi edinga (noma esifuna kithi) uhlobo oluthile lokuqamba. Kuphakathi kokuthi sisebenzisa i-SDI ngokokuqala ngqa, noma umthumeli wevidiyo, noma sidlulisa isignali sisebenzisa amamodemu ambalwa e-4G ukusuka olwandle, isilawuli kude esisha, i-matrix yesiginali, sithatha ividiyo kwicopter, sisakaza kabusha emaqenjini angama-25 e-VK, kanye njenge. Iphrojekthi ngayinye entsha ikwenza ungene emhlabeni wokusakaza-bukhoma ujule nakakhulu. Sikhuluma ngalokhu ku-YouTube VidMK, futhi sanquma ukukubhala ku-Habr.
Ngakho-ke, umsebenzi ...
Ibhola lomdanso libanjwa ku-inthanethi ngenxa yalolu bhubhane. Kukhona umbhangqwana ohamba phambili, bonke abanye ababambiqhaza bayadansa, bephinda ngemva kwabo, okungukuthi, kufanele babone futhi bezwe umbhangqwana oyinhloko kanye nomculo.
Ekuqaleni, umbusi waseSevastopol ujoyina ukuvula ibhola. Ukusakaza okuqediwe, okuqondisiwe kuya ku-YouTube, Facebook naku-VK.
Indlela esobala kakhulu kwakuwukushayela wonke umuntu ngengxoxo yevidiyo. I-Zoom yaba ngowokuqala ukufika engqondweni, kodwa ngivame ukuzama ukuthi ngingakubambeli ngokushesha engikuzwayo, kodwa ngibheke ezinye izindlela. Mhlawumbe ukumaketha kwabo kuhle, futhi noma ngabe ithuluzi lihle, mhlawumbe kukhona okunye. Bakhulume nge-TrueConf izikhathi ezimbalwa engxoxweni ye-AVstream, ngakho-ke nginqume ukuyizama.
Kubalulekile ukusho lapha ukuthi siseCrimea futhi izinsiza eziningi ezithandwayo azisebenzi lapha. Kufanele useshe, futhi ngokuvamile ezinye izindlela ziba ngcono. Ngakho-ke, isibonelo, esikhundleni se-Trello evinjiwe, siqale ukusebenzisa i-Planfix enamandla.
I-TrueConf yangikhanga ngokushesha ngethuba lokukhulisa iseva yami. Ngombono, lokhu kungasho ukuthi asincikile ekukhuleni komthwalo ojwayelekile ezikhungweni zedatha ngesikhathi sokuzihlukanisa, sihlezi ngokuthula e-Sevastopol, sixhuma ikakhulukazi abasebenzisi bendawo kanye nabambalwa abavela kwamanye amadolobha, futhi yonke into isebenza ngokuzinzile. Ngaphezu kwalokho, ukusebenzisa iseva yakho bekunenzuzo enkulu ngokwemali. Nakumakhasimende ethu nawo anikela mahhala kwazise abahleli bebhola bekungama-NGO.
Ngokuvamile, sihlole umkhiqizo futhi sabona ukuthi uyasifanela. Nakuba ukuhlolwa kungazange kugijime umthwalo ogcwele wabantu abangu-35, kwakungethusa kancane ukuthi ikhompyutha endala yayizoziphatha kanjani njengeseva. Izidingo zeyunithi yesistimu ziphezulu kakhulu ngomthwalo onjalo, ngakho-ke silethe ikhompuyutha esekelwe ku-AMD Ryzen 7 2700, futhi yaba nokuthula nayo.
Iseva ibitholakala ngokoqobo endaweni efanayo lapho ibhola belisakazwa khona. Uhlelo lokusebenza oluyinhloko lokuxhumana ngevidiyo luxhunywe kunethiwekhi efanayo neseva. Lokhu kwengeze ukuqiniseka ukuthi isithombe sizofika kuseva, bese siya ku-inthanethi kwabanye ababambi qhaza. Ngendlela, i-inthanethi kufanele ibe yinhle. Kubahlanganyeli bethu be-35, isivinini sokulayisha sifinyelele ku-120 Mbit, okungukuthi, i-intanethi evamile ye-100 Mbit ngeke yanele. Ngokuvamile, iseva iyasebenza, asihambe siyosakaza...
Isignali yekhamera
Noma iyiphi ingxoxo yevidiyo ikunikeza ukuthi ukhethe ikhamera yewebhu njengomthombo wesithombe kanye nemakrofoni yomsindo. Kuthiwani uma kudingeka sibe nekhamera yevidiyo echwepheshile nomsindo ovela kumakrofoni amabili anengoma yomsindo? Kafushane, sisebenzise i-NDI.
Bekufanele siqondise konke ukusakazwa futhi sikusakaze ezinkundleni zokuxhumana. Ukuze senze lokhu, sasinekhompuyutha eyinhloko njenge-mini-PTS (isitudiyo sikamabonakude esiphathwayo). Wonke umsebenzi wenziwa kusetshenziswa uhlelo lwe-vMix. Lena isofthiwe enamandla kakhulu yokuhlela ukusakazwa kwezinhlobo ezahlukene namazinga obunzima.
Umbhangqwana wethu odansa wathwebula ikhamera eyodwa; sasingekho isidingo sokwengeziwe. Sithwebule isiginali kukhamera sisebenzisa ikhadi langaphakathi leBlackMagic Intensity Pro. Ngokubona kwami, leli yikhadi elifanele lokuthwebula isiginali ye-HDMI eyodwa. Lesi siginali bekumele ithunyelwe njengekhamera yewebhu ku-TrueConf. Kwakungenzeka ukuguqula ngokushesha ukusakaza kube ikhamera yewebhu usebenzisa i-vMix, kodwa ngangingafuni ukunqwabelanisa yonke into kukhompyutha eyodwa. Ngakho-ke, kwasetshenziswa ikhompyutha ephathekayo ehlukile ocingweni lwenkomfa.
Ungayithola kanjani isignali kusuka kukhamera kwi-laptop? Ungakha isignali yevidiyo ebonakalayo kukhompuyutha eyodwa futhi uyibambe kunoma iyiphi enye ikhompyutha kunethiwekhi yendawo izikhathi eziningi ngokuthanda kwakho. Lena yi-NDI (I-Network Device Interface). Ngokuyisisekelo uhlobo lwekhebula elibonakalayo elingadingi ukulawulwa nganoma iyiphi indlela ekhethekile. Ububanzi bokusakaza okukodwa kwe-1080p25 cishe bungu-100 Mbit, ngakho-ke ukuze usebenze ngokuzinzile nakanjani udinga inethiwekhi ye-Gbit engu-1 noma i-Wi-Fi enkulu kuno-150 Mbit. Kodwa ikhebula lingcono. Kungaba namasiginali amaningi anjalo e-NDI kunethiwekhi yendawo eyodwa, inqobo nje uma ububanzi besiteshi banele.
Ngakho-ke, kukhompyutha yokusingatha ku-vMix sibona isignali evela kukhamera, siyithumela kunethiwekhi njengesignali ye-NDI. Kukhompyutha ephathekayo yocingo sibamba lesi siginali sisebenzisa uhlelo lwe-NDI Virtual Input oluphuma kuphakheji ye-NDI Tools (kumahhala). Lolu hlelo oluncane ludala ikhamera yewebhu ebonakalayo lapho uvula khona isignali ye-NDI oyifunayo. Eqinisweni, yilokho kuphela, ikhamera yethu ye-HDMI nge-NDI ivele ku-TrueConf.
Kuthiwani ngomsindo?
Siqoqa umsindo kumakrofoni amabili omsakazo kanye nengoma sisebenzisa isilawulikude esihle somsindo futhi siwufake ku-vMix ngekhadi lomsindo langaphandle. Yileli nani lomsindo esilithumela emoyeni nasekusakazeni kwethu i-NDI ye-TruConf. Lapho, esikhundleni se-microphone ye-laptop, sikhetha i-NewTek NDI Audio. Manje bonke abadansi bethu bayabona futhi bezwa isithombe sethu esihle nomsindo wekhwalithi ephezulu ocingweni.
Isithombe esisemoyeni
I-TrueConf ikhethe imodi yokushaya evamile, lapho wonke umuntu ebona wonke umuntu. Bekukhona nenketho lapho sibona wonke umuntu, futhi wonke umuntu ubona abethuli kuphela. Lokhu kusebenza kakhulu, kodwa-ke ngeke kube nomphumela omkhulu.
Kufomethi yokushaya ethi "wonke umuntu ubona wonke umuntu", ungakhetha noma yiliphi iwindi elidinga ukwenziwa libe likhulu. Ngakho-ke ababambiqhaza babone umbhangqwana ohamba phambili, futhi sidale omunye umsebenzisi, esisakaza isithombe esivela ku-akhawunti yakhe futhi sashintsha phakathi kwabashadile. Sichofoze ipheya esiyifunayo futhi sandisa isikrini sazo; amapheya asele abemancane ngezansi. Kwesinye isikhathi zonke izikrini zaziboniswa ukukhombisa ukuthi bangaki abantu abebedansa ekuvunyelanisweni.
Manje mayelana nokuvumelanisa
Cishe uke wazibuza ngokubambezeleka. Yebo, kwakunjalo, cishe imizuzwana engu-1-2 kuzo zombili izinkomba. Lapha sidlala umculo, umsindo ufika kubahlanganyeli kamuva, badansela lesi sigqi, futhi isithombe sabo sibuyela kithi ngisho nangemva kwesikhathi. Sinqume ukukuziba lokhu ngaphakathi kohlaka lwefomethi, kodwa isabukeka inkulu futhi inentshisekelo.
Indaba yokuvumelanisa izibukeli ingaxazululwa ngokulibazisa ngokuzenzela umsindo ekusakazeni kwethu ezinkundleni zokuxhumana. Khona-ke umbukeli wokusakazwa uzobona ukuthi abahlanganyeli badansa kanjani ngokuvumelana nesigqi somculo. Kodwa akulona iqiniso ukuthi isithombe esivela kuwo wonke umuntu siza nokubambezeleka okufanayo. Lena enye inkinga yohlelo lokusakaza, sizokwenza lokhu ngokuzayo.
Ngendlela, kunolunye uhlelo oluncane kuphakheji ye-NDI Tools - Scan Converter. Idala isignali ye-NDI ngokuthwebula isikrini sakho noma ikhamera yewebhu. Lena yindlela ongakwazi ngayo ukuhlela ukusakazwa kalula, isibonelo, imiqhudelwano ye-inthanethi ngaphakathi kwenethiwekhi yendawo, unale nethiwekhi kuphela namakhamera ewebhu. Awasekho amadivaysi adingekayo.
Kithina, lena bekungenye iphrojekthi lapho bekufanele sizame izixazululo ezintsha ebesingakahlangani nazo emifudlaneni yokulwa. Ngizokujabulela ukuphendula yonke imibono yakho, ngizofunda ngokucophelela nangentshisekelo izifiso zakho nezincomo, uma wazi ukuthi besingenza kanjani kangcono. Umhlaba wokusakaza awupheli, ubuchwepheshe obuningi buvela phambi kwamehlo ethu futhi singakwazi ukufunda ndawonye ngokushesha. Ngezansi ungabuka ividiyo yokubuka konke kusuka kusayithi.
