Ffmpeg, faka le software yasimahla yeaudio nevidiyo

Kwinqaku elilandelayo siza kujonga kwiFFmpeg. Le yenye ukuqokelelwa kwesoftware yomgca wokuyalelaImithombo yasimahla nevulekileyo yokusebenza neefayile zemultimedia. Iqulethe iseti yamathala eencwadi alalelwayo nevidiyo, njengoko zinjalo: libavcodec, libavformat kunye ne-libavutil phakathi kwabanye. NgeFFmpeg, nabani na unokuguqula phakathi kweefomathi ezahlukeneyo zevidiyo kunye nezomsindo, usete amaxabiso esampulu, wenze ubungakanani kwakhona beevidiyo, okanye urekhode idesktop yakho. Malunga neyokugqibela umntu esisebenza naye wathetha nathi ixesha elidlulileyo.

Kule migca ilandelayo siza kubona amanyathelo afanelekileyo ukuya faka iFFmpeg kwi-Ubuntu 18.04. Siza kubona ukuba singayifaka njani ingxelo yangoku ezinzileyo okanye ingxelo yokugqibela ekhoyo. Imiyalelo efanayo inokusetyenziswa kwi-Ubuntu 16.04 kunye nolunye uhambiso olusekwe kubuntu, kubandakanya iLinux Mint kunye ne-Elementary OS.

I-FFmpeg kwi-Ubuntu

Faka iFFmpeg 3.X

En los Indawo zokugcina ezisemthethweni ku-Ubuntu singafumana iFFmpeg, kwaye sinako faka ngokulula ngomphathi wephakheji efanelekileyo. Le yeyona ndlela ikhawulezayo neyona ilula yokufaka iFFmpeg kwi-Ubuntu. Nangona kunjalo, ingxelo ebandakanyiweyo kwindawo yokugcina izinto isenokungabi yinguqulelo yamva nje ekhoyo.

Njengoko ndibhala le migca, uguqulelo oluzinzileyo lwangoku olukhoyo kwii-Ubuntu 18.04 zokugcina ngu-3.4.4. Ukuba unomdla wokuba unayo le nguqulo, kuya kufuneka ulandele la manyathelo alandelayo ukuze uyifake kwi-Ubuntu 18.04.

Siza kuqala ngokuvula i-terminal (Ctrl + Alt + T). Kuyo siya kubhala oku kulandelayo ukuze sihlaziye uluhlu lweephakeji ezikhoyo:

sudo apt update

Emva koko sinako faka iFFmpeg Chwetheza lo myalelo ulandelayo:

sudo apt install ffmpeg

Emva kofakelo, ukuya Qinisekisa ukuba iphakheji ifakwe ngokuchanekileyo, sinokusebenzisa ukulandela lo myalelo. Oku kuyakuprinta into efana nale ilandelayo:

ffmpeg -version

Ukudibana nabo bonke iikhowudi kunye neekhowudi ezikhoyo, singabhala:

ffmpeg -encoders

ffmpeg -decoders

Ngayo yonke le nto ingasentla siza kuyifaka kwaye siqinisekise ukufakwa kweFFmpeg 3.X kwinkqubo yethu yoBuntu. Ngoku sinokuqala ukuyisebenzisa.

Faka iFFmpeg 4.X

Ukuba sikhetha faka ingxelo entshaNgale miyalelo ilandelayo siya kuba nakho ukufaka iFFmpeg inguqulo ye-4.x kwi-Ubuntu 18.04.

Inguqulelo 4.X yale suite yesoftware yongeza uninzi lweefilitha ezintsha, iikhowudi, kunye neekhowudi. Le nguqulo yile iyafumaneka kwi-PPA kaJonathon F. Amanyathelo angezantsi achaza indlela yokufaka iFFmpeg 4.x kwi-Ubuntu 18.04.

Siqala ngokuvula i-terminal (Ctrl + Alt + T). Kuyo siza kubhala oku kulandelayo ukongeza iPPA eyimfuneko:

sudo add-apt-repository ppa:jonathonf/ffmpeg-4

Nje ukuba uyongeze iPPA kwinkqubo yakho, unga faka iphakheji eyimfuneko ukuchwetheza:

sudo apt install ffmpeg

Ngale nto, uya kuba nohlobo lwe-4.X olufakelweyo kwinkqubo kwaye ekulungele ukusetyenziswa. Unga jonga ingxelo efakiweyo ngomyalelo ofanayo esiwusebenzisayo kwinguqulo 3.X:

ffmpeg -version

Eminye imizekelo

Xa uguqula iifayile zeaudiyo nevidiyo ngeFFmpeg, awunyanzelekanga ukuba uchaze igalelo kunye nefomathi yemveliso. Ifomathi yefayile yokufaka kunye nefomathi yemveliso ibekwe kulwandiso lwefayile.

Ukuba besifuna Guqula ifayile yevidiyo ukusuka kwi-mp4 iye kwi-webmKuya kufuneka ubhale into efana nale:

ffmpeg -i entradaVideo.mp4 salidaVideo.webm

Kwimeko apho sinomdla Guqula mp3 ifayile yefayile kwi-ogg, lo myalelo uya kuba njengoku kulandelayo:

ffmpeg -i entradaAudio.mp3 salidaAudio.ogg

Xa uguqula iifayile, siya kuba nakho Chaza iikhowudi esifuna ukuzisebenzisa nge-- c ukhetho. I-codec inokuba ligama layo nayiphi na idikhowudi / isikhowudi esixhaswayo.

Ukuba besifuna Guqula ifayile yevidiyo ukusuka kwi-mp4 iye kwi-webm usebenzisa i-codec yevidiyo ye-libvpx kunye ne-libvorbis codec yeaudio. Kuya kufuneka sisebenzise iodolo ngolu hlobo lulandelayo:

ffmpeg -i input.mp4 -c:v libvpx -c:a libvorbis output.webm

Kwimeko yokufuna Guqula ifayile yeaudio ukusuka kwi-mp3 ukuya kwi-ogg encoded kunye ne-libopus codec. Umyalelo wokusebenzisa unokuba yinto elandelayo:

ffmpeg -i entradaAudio.mp3 -c:a libopus salidaAudio.ogg

Olunye ulwazi malunga nendlela yokusebenzisa le software inokufumaneka Ukubonisana amaxwebhu asemthethweni nguFFmpeg.
