Muva nje, njengento yokuzilibazisa, bengilokhu ngiqopha izinkulumo zesazi sokusebenza kwengqondo engimaziyo. Ngihlela okuqoshiwe futhi ngikushicilele kuwebhusayithi yami. Enyangeni edlule, ngathola umqondo wokuhlela ukusakazwa kwalezi zifundo 24/7 ku-YouTube. "Isiteshi se-TV" esinendikimba esinikezelwe ekukhuleni komuntu siqu.
Ngiyazi ukwenza ukusakaza okuvamile. Kepha ungayenza kanjani ukuthi isakazwe amafayela wevidiyo? Ukuze isebenze 24/7, iyaguquguquka, izimele ngangokunokwenzeka, futhi ngesikhathi esifanayo ayincikile nganoma iyiphi indlela kukhompyutha yami yasekhaya. Yilokhu okwadingeka ngikuthole.
Kwathatha izinsuku ezimbalwa ukuthola isisombululo. Ngifunde izinkundla eziningi kanye nezincwadi ezahlukahlukene ngaphandle kwazo ukusakaza kwami bekungeke kusebenze. Futhi manje njengoba i-prank isiyimpumelelo, ngizwa isidingo sokwabelana ngesixazululo sami. Yavela kanje le ndatshana.
Kafushane, isixazululo sokugcina saba kanje: I-VPS + ffmeg + bash script. Ngaphansi kokusikwa, ngichaza izinyathelo ezithathiwe futhi ngikhulume ngezingibe ezatholwa ngesikhathi kuhlelwa ukusakaza.
Isinyathelo 1 - kuzovela kuphi ukusakaza?
Ekuqaleni, kwakudingeka ukunquma ukuthi ukusakazwa kuzovela kuphi nokuthi umthombo wakho uzoba kuphi. Into yokuqala eyafika emqondweni kwaba kusuka kukhompuyutha yakho yasekhaya. Qoqa amavidiyo uwafake ohlwini lokudlalayo bese uqala ukuwadlala kunoma yisiphi isidlali sevidiyo. Bese uthwebula isithombe sesikrini bese usisakaza ku-YouTube. Kodwa ngicishe ngenqaba ngokushesha le nketho ngoba... Ukuze uyisebenzise, udinga ukugcina ikhompuyutha yakho yasekhaya ivuliwe njalo, okusho ukuthi umsindo ovela kuma-coolers ngisho nasebusuku kanye nokwenyuka kokusetshenziswa kukagesi (+100-150 kWh njalo ngenyanga). Futhi kuvela ukuthi ngeke ukwazi ukusebenzisa ikhompuyutha yakho yasekhaya ngesikhathi sokusakaza. noma yikuphi ukunyakaza kwegundane kuzobonakala ekusakazweni.
Ngabe sengiqala ukubuka eceleni amasevisi amafu. Bengifuna isevisi eseyenziwe ngomumo lapho bengingalayisha khona amavidiyo ami noma, ngokwesibonelo, ngifake izixhumanisi zamavidiyo asuka ku-YouTube futhi wonke azopakishwa ekusakazweni okukodwa okunganqamuki. Kodwa angitholanga lutho olufanele. Mhlawumbe angizange ngiseshe kahle. Okuwukuphela kwento elingana nokusebenza i-restream.io, isevisi esiza ukusakaza ngesikhathi esisodwa kuzingxenyekazi ezimbalwa. Kubonakala sengathi ikuvumela ukuthi ulayishe amavidiyo akho. Kodwa le nsizakalo yenzelwe izinjongo ezihluke ngokuphelele futhi balindele ukuthi ukusakazwa kuzohlala amahora ambalwa kuphela. Ngicabanga ukuthi uma ngale nkonzo kungenzeka ukuhlela ukusakazwa kwewashi ubusuku nemini, khona-ke kuzodubula kube amashumi, noma ngisho namakhulu amadola ngenyanga. Kodwa bengisafuna ukuhlela ukusakaza mahhala noma ngokutshalwa kwezimali okuncane.
Kwacaca ukuthi ukusakaza kudingekile noma hlukanisa idivayisi noma ikhompyutha ehlukile. Bengicabanga into efana ne-Raspberri Pi. Yini futhi? Akanayo into epholile. Ngiqophe ividiyo ku-flash drive, ngaxhuma ikhebula le-Ethernet ngayiyeka yalala ndawana thize endaweni eseceleni ngayisakaza. Inketho. Kodwa bengingenalo ibhodi ngokwalo noma isipiliyoni sokusebenza nalo, ngakho futhi ngenqabile le nketho.
Ngenxa yalokho, ngahlangana nengxoxo ethile lapho babexoxa khona ngendalo iseva yakho ukusakaza. Bekungekona lokho kanye ebengikufuna, kodwa ngithole umqondo osemqoka - ungasebenzisa iseva! Kuleyo ngxoxo, kwaphakanyiswa ukuthi kusetshenziswe inhlanganisela ye-VPS + nginx + OBS. Kwacaca ukuthi le nhlanganisela ingangifanela nami. Okuwukuphela kwento eyangididayo ukuthi ngangingakaze ngiphathe iseva futhi kwakubonakala kimi ukuthi ukuba neseva yami ezinikele kwakudida futhi kubiza. Nginqume ukuthola ukuthi kuzobiza malini ukuqasha iseva ngokucushwa okuncane futhi ngamangala kahle.
Amanani aboniswa ngama-ruble aseBelarusian futhi lezi ziyimvuthuluka nje. Ukuze uqonde, 8 ruble Belarusian mayelana 3.5 zamadola noma 240 ruble Russian. Inyanga yokusebenzisa ikhompuyutha egcwele ngokugcwele evulwa 24/7 futhi enokufinyelela ku-inthanethi okusheshayo. Ngesizathu esithile, lokhu kutholwa kwangijabulisa kakhulu futhi izinsuku ezimbalwa ngihamba ngijabule kakhulu, njengengane ethole amarokhethi asemkhathini :)
Ngendlela, ngisebenzise ukunikezwa kwesayithi lokuqala i-Google eyanginika lona ngombuzo "Ukuqashwa kwe-VPS". Mhlawumbe kunezixazululo ezengeziwe zesabelomali, kodwa le ntengo ingifanele futhi angizange ngibheke phambili.
Lapho udala iseva, ungakhetha isistimu yokusebenza ezosebenza ngaphansi kwayo. Ungahlela ukusakaza kunoma yiziphi izinhlelo ezisohlwini futhi wenze ukukhetha ngokusekelwe kokuncamelayo namandla akho ezezimali (kuseva eneWindows icela imali eyengeziwe). Ngakhetha i-CentOS. Kungenxa yokuthi nganginolwazi oluncane ngakho ngaphambili.
Isinyathelo sesi-2 – ukusethwa kweseva
Into yokuqala oyidingayo ngemuva kokudala iseva ukuxhuma kuyo nge-SSH. Ekuqaleni ngasebenzisa i-PuTTy, kodwa ngase ngiqala ukusebenzisa i-Secure Shell App, esebenza ku-Google Chrome. Kwaba ngcono kimina.
Ngabe sengishintsha igama lomethuleli, ngamisa ukuvumelanisa isikhathi kuseva, ngabuyekeza uhlelo, ngasebenzisa ama-iptables... futhi ngenza inqwaba yezinye izinto, kodwa hhayi ngoba kwakudingekile. Benginentshisekelo yokumisa iseva futhi yangisebenzela. Ngiyayithanda uma isebenza :)
Nazi izinyathelo okudingeka uzithathe:
- Xhuma inqolobane ye-EPEL.
- Setha iseva ye-FTP (ngikhethe i-vsftp).
- Faka i-ffmpeg.
Ngeke nginikeze imiyalo ngokuningiliziwe; le miyalo iwumqondo ukuze udlulisele uhlelo olujwayelekile lomsebenzi. Uma unobunzima nganoma yiziphi izinyathelo, zingaxazululwa ngokushesha ngokusebenzisa umbuzo wenjini yokusesha njengokuthi “CentOS xhuma i-EPEL” noma “i-CentOS faka iseva ye-FTP”. Futhi kuzixhumanisi zokuqala ungathola imiyalelo enemininingwane yesinyathelo ngesinyathelo.
Ngakho-ke, njengoba ngibhale ngaphambili, bengidinga inhlanganisela ye-VPS + nginx + OBS. I-VPS - isilungile. Kodwa imibuzo yaqala ukuvela kwamanye amaphuzu. I-OBS wuhlelo lokusakaza, i-Open Broadcaster Software. Futhi isebenza kuphela ngemifudlana i.e. isibonelo, ithatha isithombe kukhamera yewebhu futhi isisakaze. Noma ukuqoshwa kwesikrini. Noma ukusakaza okuvele kuqhubeka kudluliselwa kwenye isayithi. Kodwa anginakho ukusakaza, nginesethi kuphela yamafayela evidiyo adinga ukwenziwa abe ukusakaza.
Ngaqala ukumba ngale ndlela futhi ngahlangana ne-ffmpeg. I-FFmpeg iqoqo lemitapo yolwazi yamahhala nevulekile ekuvumela ukuthi urekhode, uguqule, futhi usakaze umsindo nevidiyo yedijithali ngamafomethi ahlukahlukene.
Futhi ngamangala kakhulu ukuthi ingakanani i-ffmpeg engayenza. Uma uthanda, izokhipha umsindo kuvidiyo. Uma uthanda, izosika isiqeshana sevidiyo ngaphandle kokurekhoda kabusha. Uma ufuna, izoguqula isuka kwenye ifomethi iye kwenye. Futhi okuningi, okuningi kakhulu. Kuze kube seqophelweni lokuthi ungacacisa ifayela kuyo, izoyiguqulela ibe ukusakaza bese iyidlulisela ku-YouTube uqobo. Yilokho-ke, iketango lihlangene. Okusele ukuphothula ama-nuances.
Isinyathelo sesi-3 - ukumisa ukusakaza
Sakha ukusakaza ku-YouTube. Kulesi sigaba sidinga kuphela isixhumanisi nokhiye wokusakaza. Kusithombe-skrini esingezansi agqanyiswe ngokubomvu.
Isikhathi esilandelayo layisha amafayela evidiyo kuseva, esihlela ukusakaza. Empeleni, i-FTP idingeka kuphela kulesi sigaba. Uma unenye indlela elula yokulayisha amafayela kuseva, awudingi ukusetha iseva ye-FTP.
Sidlulisela ukusakaza ku-YouTube. Ukuze uqale ukusakaza, udinga ukusebenzisa i-ffmpeg ngezibaluli ezimbalwa. Nansi indlela umyalo omfushane engiwutholile obukeka ngayo:
ffmpeg -re -i lecture1.mp4 -f flv rtmp://a.rtmp.youtube.com/live2/%КЛЮЧ_ТРАНСЛЯЦИИ%
Ukukhishwa kwesici-re - kubonisa ukuthi ifayela kufanele liguqulwe libe ukusakaza.
-i - ikhombisa ukuthi yiliphi ifayela okufanele lidlalwe. Kubalulekile ukuthi umyalo uqaliswe kuhla lwemibhalo lapho ifayela levidiyo ngokwalo likhona. Uma kungenjalo, kufanele ucacise isixhumanisi esiphelele sefayela, njenge /usr/media/lecture1.mp4.
-f – usetha ifomethi yefayela lokuphumayo. Endabeni yami, kuvela ukuthi i-ffmpeg iguqula ifayela lami lisuka ku-mp4 liye ku-flv ngokundiza.
Futhi ekugcineni sibonisa idatha esiyithathe ku-YouTube ekhasini lezilungiselelo zokusakaza, i.e. ikheli odinga ukudlulisa idatha kulo, kanye nokhiye wokusakaza, ukuze ukusakaza kuboniswe ngokuqondile esiteshini sakho.
Uma wenze yonke into ngendlela efanele, ngemuva kokwenza lo myalo, i-YouTube izobona ukusakazwa okudlulisiwe. Ukuze uqale ukusakaza, udinga nje ukuchofoza inkinobho ethi "Qala Ukusakaza" ku-YouTube ngokwayo.
Isinyathelo sesi-4 - engeza ukuzimela
Siyakuhalalisela! Manje uyazi ukuthi ungaqala kanjani ukusakaza kusuka kufayela levidiyo. Kodwa lokhu akwanele ekusakazeni kuka-XNUMX/XNUMX. Kubalulekile ukuthi ngemva kokuba ividiyo yokuqala isiqedile ukudlala, elandelayo iqale ngokushesha, futhi lapho wonke amavidiyo esebonisiwe, ukudlalwa kuqale futhi.
Ngiqhamuke nenketho elandelayo: dala ifayela elithi .sh engibhale kulo umyalo wefayela ngalinye levidiyo futhi ekugcineni ngabonisa umyalo wokuqalisa iskripthi esifanayo futhi. Umphumela uba ukuphindaphinda okufana nalokhu:
Команда 1... (запуск трансляции файла lecture1.mp4)
Команда 2... (запуск трансляции файла lecture2.mp4)
Команда 3... (запуск трансляции файла lecture3.mp4)
bash start.shFuthi, yebo, kwasebenza. Ngeneliseke, ngethula uhlelo lokuhlola bese ngilala.
Ekuseni ngilindelwe isimanga esingemnandi. Kuvele ukuthi ukusakaza kuthathe imizuzu embalwa kuphela futhi kwaphela ngokushesha njengoba ngicisha ikhompuyutha yami. Uphenyo lubonise ukuthi imiyalo eqaliswe ngale ndlela isetshenziswa ngenkathi umsebenzisi egunyaziwe kuseva. Lapho nje nginqamula, imiyalo engangiyiqhuba yaphazamiseka. Ukuvimbela lokhu ukuthi kungenzeki, kwanele phambi kweqembu bash engeza umyalo nohup. Lokhu kuzovumela inqubo esebenzayo ukuthi isebenze ngokunganaki ubukhona bakho.
Inguqulo encane yokugcina yesikripthi ibonakala kanje:
ffmpeg -re -i lecture1.mp4 -f flv rtmp://a.rtmp.youtube.com/live2/%КЛЮЧ_ТРАНСЛЯЦИИ%
ffmpeg -re -i lecture2.mp4 -f flv rtmp://a.rtmp.youtube.com/live2/%КЛЮЧ_ТРАНСЛЯЦИИ%
ffmpeg -re -i lecture3.mp4 -f flv rtmp://a.rtmp.youtube.com/live2/%КЛЮЧ_ТРАНСЛЯЦИИ%
nohup bash start.sh $Lapho i-start.sh kuyifayela okubhalwe kulo lesi script. Futhi leli fayela kufanele libe kunkomba efanayo namafayela evidiyo.
Ukwengeza uphawu lwedola ekugcineni kuvumela inqubo ukuthi isebenze ngemuva ukuze uqhubeke nokusebenzisa ikhonsoli ngaphandle kokuphazamisa ukusakaza.
Amabhonasi afaka phakathi izinto ezilandelayo:
- Ungakwazi ukushintsha mathupha ukudlalwa kwefayela. Ukwenza lokhu, udinga "ukubulala" inqubo ye-ffmpeg esebenzayo njengamanje. Ngemva kwalokhu, ukudlalwa kwefayela elilandelayo ohlwini kuzoqala ngokuzenzakalelayo.
- Amavidiyo amasha angengezwa ekusakazweni ngaphandle kokumisa ukusakaza. Vele ulayishe ividiyo kuseva, engeza umyalo wokusebenzisa leli fayela kusikripthi, bese uligcina. Yilokho kuphela. Emzuliswaneni olandelayo wokudlala, ifayela elisha lizosakazwa kanye namafayela amadala.
Isinyathelo sesi-5 - yenza ngendlela oyifisayo i-ffmpeg
Empeleni, besingayeka lapho. Kodwa bengifuna ukwenza ukusakazwa kube nobungane kancane ezibukelini.
Ake sithi umuntu uye emsakazweni, waqala ukubukela, wakuthanda futhi wayefuna ukubuka lesi sifundo kusukela ekuqaleni, kodwa ukusakaza akuvumeli ukuhlehliswa. Ukuze ubuke inkulumo kusukela ekuqaleni, umuntu uzodinga ukuya kuwebhusayithi yami futhi athole ukurekhodwa kwenkulumo enentshisekelo. Ungabona kanjani ukuthi iyiphi inkulumo ayithandayo? Sekuvele kunezinkulumo eziyi-16 esizeni futhi ziningi kuphela isonto ngalinye. Ngicabanga ukuthi nami, engithwebule futhi ngahlela zonke lezi zifundo, ngeke ngikwazi ukunquma eqeqebeni elingahleliwe ukuthi isiphi isifundo. Ngakho-ke, kuyadingeka ukuthi inkulumo ngayinye ikhethwe ngandlela thize.
Inketho yokwengeza amagama-ncazo kumafayela evidiyo angumthombo ohlelweni lokuhlela ayizange ingifanele. Kwakudingekile ukuqinisekisa ukuthi amafayela okuqala asetshenzisiwe. Ngakho lokho kusekela ukusakaza kudinga ukunyakaza komzimba okuncane ngangokunokwenzeka kimi.
Kwavela ukuthi i-ffmpeg ingangisiza nalokhu. Inemfanelo ekhethekile -vf, okuvumela umbhalo ukuthi ubekwe phezu kwevidiyo. Ukwengeza umbhalo kuvidiyo, udinga ukwengeza isiqeshana esilandelayo emyalweni:
-vf drawtext="fontfile=OpenSans.ttf:text='Лекция 13: Психология эмоций. Как создавать радость?':fontsize=26:fontcolor=white:borderw=1:bordercolor=black:x=40:y=670"
Incazelo yamapharamithafontfile= – isixhumanisi sefayela lefonti. Ngaphandle kwalokhu, amagama-ncazo ngeke engezwe kuvidiyo. Indlela elula ukufaka ifayela lefonti kufolda efanayo nevidiyo. Noma uzodinga ukucacisa indlela ephelele eya kufayela.
text= - empeleni, umbhalo ngokwawo odinga ukubekwa phezu kwevidiyo.
fontsize= - usayizi wefonti ngamaphikseli.
fontcolor= – umbala wefonti.
borderw= – ukujiya kohlaka oluzungeze umbhalo ngamaphikseli (nginombhalo omhlophe onohlaka olumnyama oluwugqinsi lwephikseli elingu-1).
bordercolor= – umbala wohlaka.
x= и y= – umbhalo izixhumanisi. Ichashazi 0;0 itholakala ekhoneni eliphezulu kwesokunxele. Izixhumanisi zami zikhethwa ngendlela yokuthi umbhalo ubekwe ekhoneni elingezansi kwesokunxele ngesinqumo sevidiyo samaphikseli angu-1280x720.
Kubukeka kanjena:
Isinyathelo sesi-6 - nquma ikhwalithi yokusakaza
Yilokho kuphela, ukusakaza sekulungile. Ukusakaza kwe-FFmpeg, amafayela ayadlalwa, ubukhona bami abudingeki ekusakazeni. Ngisho zonke izifundo zisayinwe. Kubukeka sengathi kunjalo.
Kodwa enye i-nuance eyodwa ivele - ngikhethe ukucushwa kweseva okuncane futhi ayizange ikhiphe ukusakaza. Ukucushwa kweseva: 1 core (ofana no-2.2 GHz), 1 gigabyte ye-RAM, 25 GB SSD. Kwakukhona i-RAM eyanele, kodwa iphrosesa yacishe yalayishwa ngokuphelele ku-100% (futhi ngezinye izikhathi ngisho no-102-103% :) Lokhu kuholele ekubeni ukusakazwa kube yiqhwa njalo emizuzwaneni embalwa.
Ungase umane uthathe ukucushwa okumba eqolo ngama-cores amabili, ngenhlanhla, ngobuchwepheshe bamafu, ukushintsha ukucushwa kweseva kwenzeka ngokucindezela izinkinobho ezimbalwa. Kodwa bengifuna ukulingana nomthamo omncane wokumisa. Ngiqale ukufunda imibhalo ye-ffmpeg futhi yebo, kukhona nezilungiselelo lapho ezikuvumela ukuthi ulawule umthwalo ohlelweni.
Ikhwalithi ephezulu yesithombe ingafinyelelwa ngezindlela ezimbili: kungaba umthwalo ophezulu we-CPU noma ithrafikhi ephezulu ephumayo. Kuvele ukuthi uma iprosesa ingathwala umthwalo omningi, kuzodingeka umkhawulokudonsa wesiteshi omncane. Noma awukwazi ukulayisha iphrosesa kakhulu, kodwa uzodinga isiteshi esibanzi esine-headroom enkulu yethrafikhi. Uma kunemikhawulo kukho kokubili iphrosesa kanye nosayizi wesiteshi/ithrafikhi ephumayo, kuzomele wehlise ikhwalithi yesithombe ukuze ukusakazwa kuhambe kahle.
Iseva yami inokufinyelela kusiteshi esibanzi esingu-10 Mbit/s. Lobu bubanzi bulungile. Kodwa kunomkhawulo wethrafikhi - 1 TB ngenyanga. Ngakho-ke, ukuze uhlangabezane nemikhawulo yethrafikhi, ukugeleza kwami okuphumayo akufanele kudlule ku-~300 KB ngomzuzwana i.e. I-bitrate yokusakaza okuphumayo akufanele ibe ngaphezu kuka-2,5 Mbit/s. I-YouTube, ngendlela, incoma ukusakaza ngale-bitrate.
Ukulawula umthwalo ohlelweni, i-ffmpeg isebenzisa izindlela ezihlukene. Kubhalwe kahle ngalokhu . Ngagcina ngisebenzise izimfanelo ezimbili: -crf и -preset.
I-Constant Rate Factor (CRF) - lokhu kuyi-coefficient yokubonga ongalungisa ngayo ikhwalithi yesithombe. I-CRF ingaba namanani ukusuka ku-0 kuye ku-51, lapho u-0 eyikhwalithi yefayela lomthombo, i-51 iyikhwalithi embi kakhulu. Kunconywa ukusebenzisa amanani asuka ku-17 kuye ku-28, okuzenzakalelayo kungu-23. Nge-coefficient engu-17, ividiyo izofana ngokubukeka neyokuqala, kodwa ngokobuchwepheshe ngeke ifane. Amadokhumenti aphinde athi usayizi wevidiyo yokugcina, kuye nge-CRF eshiwo, ushintsha kakhulu, i.e. ukukhulisa i-coefficient ngamaphoyinti angu-6 kuzophinda kabili i-bitrate yevidiyo ephumayo.
Uma usebenzisa i-CRF ungakhetha “isisindo” sesithombe esiphumayo, bese usebenzisa ukusetha ngaphambilini (-preset) unganquma ukuthi iprosesa izolayishwa kangakanani. Lesi sibaluli sinamapharamitha alandelayo:
ultrafastsuperfastveryfastfasterfastmedium– inani elimisiweslowslowerveryslow
Ipharamitha "esheshayo" icacisiwe, umthwalo omningi kuphrosesa uzoba phezulu.
Ngiqale ngakhetha ukusetha ngaphambilini okwakunzima kakhulu kuphrosesa yami, ngase ngikhetha kahle kakhulu umthwalo ngisebenzisa i-CRF. Endabeni yami, ukusetha ngaphambilini kusebenze fast, futhi nge-crf ngahlala enanini elingu-24.
isiphetho
Yilokho kuphela. Umyalo wokugcina wokuqala ukusakaza yilo:
ffmpeg -re -i lecture1.mp4 -vf drawtext="fontfile=OpenSans.ttf:text='Лекция 1: Жонглирование картинами мира':fontsize=26:fontcolor=white:borderw=1:bordercolor=black:x=40:y=670" -c:v libx264 -preset fast -crf 24 -g 3 -f flv rtmp://a.rtmp.youtube.com/live2/%КЛЮЧ_ТРАНСЛЯЦИИ%Kunamaphuzu amabili kuphela angachazwanga asele lapha:
1) -c:v libx264 – ecacisa ikhodekhi ethile yokusebenza nefayela lomthombo.
2) -g 3 – inkomba ecacile yenani lamafreyimu abalulekile. Kulokhu, kucaciswa ukuthi uhlaka ngalunye lwesithathu kufanele lube uzimele ongukhiye. Inani elijwayelekile lingaba ngu-5 noma 8, kodwa i-YouTube iyafunga futhi icela okungenani oku-3.
Ungabona ukuthi ukusakaza kube yikhwalithi enjani .
Ukulayisha kuseva bekulokhu okulandelayo:
Ngokusekelwe kudatha yokuqapha, kuyacaca ukuthi umthwalo weprosesa usukela ku-70% kuya ku-95% futhi phakathi nesonto ukusakaza akukaze kufinyelele ku-100%. Lokhu kusho ukuthi ngalezi zilungiselelo iphrosesa yanele.
Ngokulayisha idiski, ngingasho ukuthi cishe ayilayishwanga futhi i-HDD evamile kufanele yanele ukusakaza.
Kodwa inani lethrafikhi eliphumayo liyangikhathaza. Kuvele ukuthi ukusakaza kwami okuphumayo kusuka ku-450 kuya ku-650 KB ngesekhondi. Ngenyanga lokhu kuzoba cishe ama-terabytes angu-1,8. Kungase kudingeke uthenge ithrafikhi eyengeziwe noma ushintshele ekucushweni okunamacores amabili ngoba... Angithandi ukwehlisa izinga lesithombe.
***
Ngenxa yalokho, ngizosho ukuthi ukusetha ukusakazwa okunjalo kusukela ekuqaleni kuthatha cishe amahora angu-1-2. Ngaphezu kwalokho, ukulayisha ividiyo kuseva kuzothatha isikhathi esiningi.
Ukwethulwa kokusakaza okunjalo akuzange kuziphendulele njengethuluzi lokumaketha. Mhlawumbe, uma sikhulisa ukubukwa ukuze ama-algorithms e-YouTube athathe lokhu kusakaza futhi aqale ukukubonisa ngenkuthalo ezincomweni, khona-ke kukhona okuzolunga. Endabeni yami, ezinsukwini eziyi-16 zokusakazwa okuqhubekayo kwabukwa izikhathi ezingama-58.
Kulungile lokho. Ukusakaza kufanelana kahle ekhasini eliyinhloko lewebhusayithi yami. Lokhu kwanginika ithuba lokwakha owami umbono ngokushesha mayelana nomfundisi kanye nezifundo ngokwazo.
Futhi umzuzwana owodwa. Kubalulekile ukuthi ukusakaza kungaphuli i-copyright yanoma ubani, ngaphandle kwalokho kuzovinjwa. Ngehlise umoya ngokusakaza kwami ngoba... Ngikhethe ngokukhethekile ukufakwa komculo okusetshenziswa mahhala, futhi umbhali wokuqukethwe uhlala ekhompyutheni eseduze futhi akaphikisani nhlobo nami ngisebenzisa okuqukethwe kwakhe :)
Kodwa uma unomsakazo odlala ngemuva kwenye indawo ekusakazeni kwakho, noma usebenzise ithrekhi oyikhonzile ngesikhathi uhlela, noma uthathe ukulandelana kwevidiyo kuvidiyo yomculo edumile, uchungechunge lwe-TV noma ifilimu, ukusakaza kwakho kusengcupheni. Kubalulekile futhi ukuthi ukusakaza kuthwale okungenani umthwalo we-semantic omncane, ngaphandle kwalokho kungase kuvinjwe njengogaxekile.
***
Yilokho kuphela enginakho. Ngethemba ukuthi leli bhukwana lizosebenzela othile kahle. Hhayi-ke, uma unokuthile ongakwengeza, bhala, ngizokujabulela ukufunda izengezo kanye nezincazelo ezihlokweni.
