Los Iirekhodi zokurekhoda zeVHS (VCRs) Abayi kubakho ngonaphakade, kwaye iiteyiphu zeVHS aziyi kuhlala ngonaphakade, kancinci kancinci kuya kusiba nzima ngakumbi ukugcina zonke iividiyo kule fomathi yakudala. Ukuba imalunga nemiboniso bhanyabhanya, ubukhulu becala sele belungisiwe kwaye bafakwa ekhompyutheni, ngenxa yoko siya kubafumana kwifomathi ezinje ngeDVD, BD, njl. Kodwa asizukufumana zonke iividiyo ezifakwe ekhompyutheni, yile meko yokurekhodwa ekhaya.
Ke ngoko, ukuba unesishicileli sevidiyo seVHS kwiTV yakho, kungcono ukuqala ngokukhawuleza kangangoko kunokwenzeka uyiguqulele kwifomathi yedijithali ukukwazi ukuyigcina ngendlela eyomelele ngakumbi nekhuselekileyo, ukuthintela ilahleko yezi vidiyo xa singasakwazi ukufumana iiVCR, nkqu nesesibini. Kwaye inkqubo ilula kunokuba ucinga, kwaye inokwenziwa desde Linux...
I-1-Hardware iyafuneka:
Into yokuqala kukuba ne- I-VCR okanye iVCR ukudlala iteyiphu yeVHS. Kwikhompyuter esiyisebenzisela uguquko, kuya kufuneka kwakhona ibe yinto esisiseko, a ikhadi lokubamba ividiyo. Ukuba usebenzisa ilaptop ungabafumana bangaphandle kwaye ukuba usebenzisa i-desktop, unokukhetha i-PCI.
Khetha ikhadi elihambelana neLinux, oko kukuthi, kukho abaqhubi beekernel zasimahla. Oku bekusoloko kuyintloko, kodwa kule mihla kuyinto eqhelekileyo ukuba eyaziwa kakhulu sele inenkxaso yeLinux (Hauppauge, Avermedia, ...). Kungenzeka ukuba xa usebenzisa i-100% ye-distro yasimahla uya kuba neengxaki zokufaka iiphakheji ezithile zekhowudi kunye ne-firmware ethile enje ivtv-firmware.
Nje ukuba ikhadi lokufaka ividiyo lifakwe, kufuneka libe nonxibelelwano lweRCA ukuze likwazi ukuyixhuma nge Intambo yeRCA kwiVCRYonke into ilungele ukuqala uguquko okanye ukwenziwa kwamanani.
2-Jonga imveliso yevidiyo
Nje ukuba yonke into idityaniswe kwaye ilungile, kuya kufuneka sivule isidlali sevidiyo esifana neVLC okanye mplayer ukuze sikwazi jonga imveliso yevidiyo ukuba siqhagamshele kwigalelo lethu lesishicileli sevidiyo sifakwa ngokuchanekileyo. Ngaphandle koko kuya kuba yimfuneko ukufakela abaqhubi ngokufanelekileyo okanye iphakheji endikhe ndayichaza ngasentla. Ngokomgaqo akufuneki kubekho ngxaki, yonke into kufanelekile kwaye ibone ividiyo edlala kwiVCR.
Kuya kufuneka unazo nezinye iiphakheji ezisisiseko ezifakwe njenge ffmpeg kunye v4l-utils ukusebenza nomqondiso wevidiyo ... Kwaye uyiqwalasele ukuba yamkele igalelo le-RCA (ukuba unentambo ye-coaxial okanye ye-S-vidiyo kuya kufuneka ulitshintshe eli nyathelo):
v4l2-ctl -i 2
3-Qalisa ukwenza ikhompyutha ngokwamanani
ukuba qala ukurekhoda Okungena kuthi ngesixhobo sokubamba ividiyo, singasebenzisa iinkqubo ezahlukeneyo, nangona ukhetho olufanelekileyo kukusebenzisa ngokuthe ngqo mplayer ukuze ithathe isixhobo sethu sokubamba, kwimeko yethu / dev / ividiyo0:
mplayer -cache 8192 /dev/video0 -dumpstream -dumpfile mi_video.mp4
Kwaye ngaloo nto siya kufumana i- ividiyo yedijithali ibizwa my_video.mp. Ngendlela, qiniseka ukuba ividiyo iphinde yabuya ngokuchanekileyo okanye uya kuthi uyibambe kuphela ividiyo ngokuyinxenye ...
Ndilunge kakhulu, enkosi kakhulu ngokwabelana ngokungenayo, ngenxa yenxalenye yam, kuba sisicatshulwa sokuqala endisiphononongayo malunga nendlela yokufaka ekhompyutheni ezo teyiphu; Ngapha sineteyipu ukusukela ngonyaka we-1998 kwaye ndigcina amaxesha osapho kuyo, endaweni yokuba neli nyathelo lokuqala ndizikhuthaze ngomnqweno ongaphezulu wokwenza eli nyathelo kwaye yonke into ihamba kakuhle kakhulu, enkosi! 😀
Enkosi kakhulu ngenqaku, baninzi abazibuza ngokuchanekileyo lo mbuzo kwaye inokuba yindlela elungileyo yokwenza ubabalo okanye ukufumana imali encinci.
Ndibona ukuphuculwa kwinqaku njengoko kuya kuba kukugqibela ukusebenzisa ifomathi yoxinzelelo lwangoku ukunciphisa ubungakanani ngaphandle kokuphulukana nomgangatho: i-h.265 yanamhlanje okanye i-HEVC.
Ndifumene indawohttps://trac.ffmpeg.org/wiki/Encode/H.265apho bachaze indlela yokucinezela kule khowudi kodwa i-audio aac ayinayo ngokungagqibekanga kwiLinuxMint 18 okanye Ubuntu 16.04 ke kuye kwafuneka ndihlaziye nge:
I-sudo add-apt-repository ppa: jonathonf / ffmpeg-3
uhlaziyo lwe-sudo apt && sudo apt ukuphucula
Umyalelo ngu:
ffmpeg -ifayile yefayile -c: v libx265 -crf 28 -c: aac -b: 128k entsha.mp4
Ndikusebenzisile konke oku ukuhambisa iiteyiphu ze-minidv ukusuka kwi-camcorder ukuya kwikhompyuter nge-firewire kunye neyure ethathe malunga ne-12 gigabytes eluhlaza yandishiya kwi-megabytes ezingama-300.
Ukuba yenziwe ngeefayile ezininzi ngaxeshanye, emva koko kwilogo:
kuba i / source_path / *; yenza ffmpeg -i "$ i" -c: v libx265 -crf 28 -c: aac -b: 128k "$ {i%. *}. mp4"; yenziwe
Tiu ĉi ezi ĉio.
I-gmolleda ngumbuzo ndizama ukuthatha i-handycam kwikhamera endala yevidiyo kodwa andazi ukuba ndenze njani ngaphambi kokuba ndiyifumane nge-kino emva koko nge-kdenlive kodwa ngoku i-kino ngathi ayisekho kwaye i-kdenlive ayisenayo inketho kwaye ithi yenze enye nge-dvgrab kodwa ayisebenzi, inika impazamo kwaye andazi ukuba ndenzeni. Ndingaluvuyela uncedo lwakho.
