Njengoba ngivele ngakutshela ezihlokweni ezedlulekusuka ukuphela kwe-linux singenza konke esikufunayo, esifundweni engizosithuthukisa ngezansi, ngizokufundisa ukuthi ungayisebenzisa kanjani i- umyalo avconv -i.
Lo myalo uzosisiza ukuthola ulwazi mayelana namafayela wemultimedia noma uwaguqulele kwamanye amafomethi iyahambisana.
Zenzelwe kanjani lezi zifundo abasebenzisi be-novice LinuxNgeke senze izimpilo zethu zibe nzima kakhulu futhi ngizokufundisa imiqondo ewusizo kakhulu futhi elula ukuyiqonda.
Ukufaka i-avconv, kufanele sivule ukuphela okusha bese uthayipha:
sudo apt-get ukufaka i-avconv
El cUmyalo wokuthola imininingwane kunoma yiliphi ifayela le-multimedia ungokulandelayo:
avconv -i kanye negama lefayela nokwandiswa kwalo, isibonelo, avconv -ividiyo.mp4
Ngalo myalo, i-terminal izobuyisa lonke ulwazi oluhlobene nevidiyo ekhethiwe.
Iguqula amafomethi wevidiyo
Ukuguqula kusuka kwifomethi ye-mpeg noma ye-avi, kulula njengokuthayipha umugqa olandelayo ku-terminal:
i-avconv -ividiyo.avi iguqulwe ividiyo.mpeg
IVideo.avi kuzoba yifayela eliwumthombo futhi ividiyo iguqule ifayili okuyilo noma ividiyo esele iguquliwe.
Lokhu kuzoba ukuwuguqula ususe ku-avi uye ku-mpeg, futhi singakwenza kusuka ku-mpeg kuye ku-avi ngendlela efanayo:
i-avconv -i video.mpeg iguqulwe ividiyo.avi
Njengoba ukwazi ukubona, ukuguqula kusuka kwividiyo kuya kuvidiyo kulula kakhulu.
Ukukhipha umsindo kusuka kuvidiyo kuya ku-mp3
Lapha indlela yokusebenzisa umyalo iyefana, ukuphela kwento eba nzima kancane ngoba kufanele siyitshele ngqo lizoba kanjani ifayela le-mp3 elidaliwe, ukuze sikhiphe umsindo siye kufayela levidiyo kuzofanele sithayiphe okulandelayo:
avconv -i vidiyo.avi -vn -ar 44100 -ac 2 -ab 192 -f mp3 audio.mp3
Lapho i-video.avi yifayela levidiyo efakwayo ne-audio-mp3 yifayela elitholiwe.
Njengoba ukwazi ukubona, kufanele sicacise ama-Kbs wefayela le-mp3 kanye nezinga lemvamisa.
Ngokulandelayo sizokwenza i- ukuvivinya umzimba okuningana ukuze ubone inqubo okufanele uyilandele.
Ukuzivocavoca 1: ukuguqula kusuka ku-avi (mp4) uye kwi-mpeg
Sivula itheminali entsha bese sithayipha indlela lapho sigcine khona amavidiyo:
cd Amavidiyo
bese sithayipha umyalo we-ls ukuhlunga okuqukethwe kufolda noma umkhombandlela:
ls
Manje njengoba ukwazi ukubona esithombeni esingenhla, kuzodingeka sisebenzise umyalo kuphela avconv -i, igama levidiyo elizoguqulwa, kulokhu ukuhlolwa.mp4 nefayela lapho sifuna ukuliguqula khona, kuleli cala okungaba njalo ukuhlolwa.mpeg:
avconv -i test.mp4 test.mpeg Ngalo myalo ukuphela kuzoqala ukusebenza ekuguqulweni kwevidiyo ekhethiwe:
Ukuzivocavoca 2: kusuka kuvidiyo kuya ku-mp3
Esikhathini sokugcina sizosebenzisa umugqa:
avconv -i test.mpeg -vn -ar 44100 -ac 2 -ab 192 -f mp3 audio.mp3
Umyalo avconv -i izosisebenzela ngezinto eziningi, yize lapha ngikufundisile Okuyisisekelo kakhulu ukuzivikela.
Imininingwane engaphezulu - Ukungena ku-terminal: ukuvuselela nokufaka izinhlelo zokusebenza
Sengivele ngiguqule ividiyo efanayo yamafomethi ahlukile, futhi ingikhombisa imivimbo eyisikwele, ngaphezu kokungangivumeli ukuthi ngiguqulele kumafomethi engiwafunayo, ingasaphathwa eyokumisa imininingwane enjengosayizi, isilinganiso sebhithi, njll. Ngoba njengoba kunjalo, angikuniki okwesihlanu.
Ingabe unawo wonke ama-codec alalelwayo afakiwe?
Umngane Bonteruel, i-avconv isiguquli se-Libav, okuyimfoloko ye-FFMPEG. Iza ifakwe ngokuzenzakalela ku-Debian, Ubuntu, njll. Akuyona into entsha, futhi ayikho kumanabukeni.
http://en.wikipedia.org/wiki/Libav
Ngokusobala, noma yiluphi uhlelo lungathuthukiswa. Kepha, uma unezinkinga zokufaka ikhodi kumafayili, impela, noma ngabe awubhalanga kahle umugqa (akekho owathi ubulula), noma, njengoba uFrancisco esho, ungaba nenkinga yokumisa kwikhompyutha yakho.
Ungasebenzisa i-WinFF noma i-Avidemux, ene-graphical interface, zinhle kakhulu ... futhi, ngaphakathi, zisebenzisa i-FFMPEG. Ngamanye amagama, okufanayo.
Ukubingelela!

Nginenkinga, futhi ngine-interactive .swf futhi ikwazi ukuguqula kuze kube ikhefu lokuqala, ngabe usazi noma yisiphi isisombululo?
Siyabonga!
