I-Los VHS tape recorders (ama-VCR) Ngeke zihlale zikhona unomphela, futhi amateyipu e-VHS ngeke ahlale unomphela, ngakho-ke kancane kancane kuzoba nzima kakhulu ukugcina wonke amavidiyo wethu efomethi endala. Uma kumayelana nama-movie, kungenzeka ukuthi aselungisiwe kabusha futhi afakwa ekhompyutheni, ngakho-ke sizowathola ngezakhiwo ezifana ne-DVD, BD, njll. Kepha ngeke sithole wonke amavidiyo afakwe ekhompyutheni, lokhu kwenzeka lapho siqopha amakhaya ethu.
Ngakho-ke, uma unesirekhodi sevidiyo se-VHS ku-TV yakho, kungcono ukuthi uqale ngokushesha okukhulu liguqulele kufomethi yedijithali ukuze sikwazi ukuyigcina ngendlela ehlala isikhathi eside futhi evikelekile, ukuvimbela ukulahleka kwalawa mavidiyo lapho singasakwazi ukuthola ama-VCR, ngisho namasekeni. Futhi inqubo ilula kunalokho ocabangayo, futhi ingenziwa desde Linux...
1-Hardware edingekayo:
Into yokuqala ukuthi ube ne- I-VCR noma i-VCR ukudlala i-VHS tape. Kukhompyutha esiyisebenzisela ukuguqulwa, kuzodingeka futhi into eyisisekelo, i ikhadi lokuthwebula ividiyo. Uma usebenzisa i-laptop ungabathola bengaphandle futhi uma usebenzisa ideskithophu, mhlawumbe ukhetha i-PCI.
Khetha ikhadi elihambisana neLinux, okungukuthi, kukhona abashayeli be-kernel bamahhala. Lokhu kuke kwaba yikhanda, kepha kulezi zinsuku kuvamile ukuthi okwaziwa kakhulu sekuvele kunesisekelo seLinux (Hauppauge, Avermedia, ...) Kungenzeka ukuthi uma usebenzisa i-distro yamahhala engu-100% unezinkinga zokufaka amaphakheji athile we-codec ne-firmware ethile efana ne- ivtv-firmware.
Uma ikhadi lokuthwebula ividiyo selifakiwe, kufanele libe nokuxhumeka kwe-RCA ukuze likwazi ukulixhuma ngefayela le- Intambo ye-RCA ku-VCR, konke sekumi ngomumo ukuqala ukuguqulwa noma ukwenziwa kwedijithali.
2-Hlola okukhipha ividiyo
Lapho konke sekuxhunyiwe futhi sekumi ngomumo, kufanele sivule isidlali sevidiyo esinjengoVLC noma i-mplayer ukuze sikwazi hlola okukhipha ividiyo ukuthi sixhume kokufakile kwethu kwirekhoda yevidiyo kuthathwa ngendlela efanele. Ngaphandle kwalokho kuzodingeka ukufaka kahle abashayeli noma iphakethe esengivele ngishilo ngenhla. Ngokomthetho akumele kube nenkinga, konke kufanele kube KULUNGILE futhi ubone ividiyo edlala ku-VCR.
Kufanele futhi ube namanye amaphakheji ayisisekelo afakwe njenge i-ffmpeg ne-v4l-utils ukusebenza nesiginali yevidiyo ... Futhi uyilungiselele ukwamukela okokufaka kwe-RCA (uma unentambo ye-coaxial noma ye-S-video kuzofanela ushintshe lesi sinyathelo):
v4l2-ctl -i 2
3-Qala ukwenza idijithali
para qala ukuqopha okungena kithi ngedivayisi yokuthwebula ividiyo, singasebenzisa izinhlelo ezahlukahlukene, noma inketho enhle yalokhu ukusebenzisa i-mplayer ngqo ukuze ithathe kusuka kudivayisi yethu yokuthwebula, kithi / dev / video0:
mplayer -cache 8192 /dev/video0 -dumpstream -dumpfile mi_video.mp4
Futhi ngalokho sizothola i- ividiyo edijithali ibizwa ngokuthi i-my_video.mp. By the way, qiniseka ukuthi ividiyo isetshenziswe kabusha ngendlela efanele noma uzothatha ividiyo kancane ...
Nginomusa kakhulu, ngiyabonga kakhulu ngokwabelana ngalokhu okufakiwe, ngokwengxenye yami, ngoba kungumbhalo wokuqala engiwubukezayo wokuthi ungawafaka kanjani amakhompyutha kulawo mateyiphu; Ngapha sineteyipu kusukela ngonyaka we-1998 futhi ngigcina izikhathi zomndeni kuyo, kunalokho ngalesi sinyathelo sokuqala ngiyazikhuthaza ngesifiso esiningi sokwenza lesi sinyathelo nokuthi konke kuhamba kahle kakhulu, ngiyabonga! 😀
Ngiyabonga kakhulu ngale ndatshana, baningi abazibuza ngokunembile ngalo mbuzo futhi kungaba yindlela enhle yokwenza okuhle noma ukuthola imali encane.
Ngibona ukuthuthuka kwendatshana njengoba kungaba ukuthi ekugcineni sisebenzise ifomethi yesimanjemanje yokucindezela ukunciphisa usayizi ngaphandle kokulahlekelwa ikhwalithi: i-h.265 yesimanje noma i-HEVC.
Ngithole indawohttps://trac.ffmpeg.org/wiki/Encode/H.265lapho bechaza khona ukuthi bangacindezela kanjani kuleyo codec kepha i-audio aac ayinayo ngokuzenzakalela i-LinuxMint 18 noma Ubuntu 16.04 ngakho-ke bekufanele ngivuselele nge:
i-sudo engeza-apt-repository ppa: jonathonf / ffmpeg-3
ukuvuselelwa kwe-sudo apt && sudo apt ukuthuthukisa
Umyalo uwukuthi:
ffmpeg -i filefile -c: v libx265 -crf 28 -c: aac -b: a 128k new.mp4
Ngikusebenzise konke lokhu ukudlulisa amateyipu ama-minidv kusuka ku-camcorder kuya kwikhompyutha nge-firewire kanti ihora elithathe cishe ama-gigabyte aluhlaza ayi-12 lingishiyile kuma-megabytes angama-300.
Uma kwenziwa ngamafayela amaningi ngasikhathi sinye, lapho-ke ku-loop:
ngoba i ku / source_path / *; yenza ffmpeg -i "$ i" -c: v libx265 -crf 28 -c: aac -b: a 128k "$ {i%. *}. mp4"; kwenziwe
Tiu ĉi lezi ĉio.
gmolleda umbuzo Ngizama ukuthatha ikhamela yesandla kusuka kukhamera endala yevidiyo kepha angazi ukuthi ngingakwenza kanjani ngaphambi kokuthi ngiyithathe nge-kino bese ngine-kdenlive kepha manje i-kino ngathi ayisekho futhi i-kdenlive ayisenayo inketho bese ithi ukuyenza nge-dvgrab kepha ayisebenzi, inika iphutha futhi angazi ukuthi ngenzeni. Ngingaluthokozela usizo lwakho.
