Ffmpeg, faka le software yamahhala yomsindo nevidiyo

Esihlokweni esilandelayo sizobheka i-FFmpeg. Lokhu kungenye ukuqoqwa kwesoftware yomugqa, umthombo wamahhala futhi ovulekile, ukusebenza ngamafayela wemultimedia. Kuqukethe i- iqoqo lemitapo yolwazi elalelwayo nevidiyo, njengoba zinjalo: libavcodec, libavformat ne-libavutil phakathi kwabanye. Nge-FFmpeg, noma ngubani angaguqula phakathi kwamafomethi ahlukahlukene wevidiyo nawomsindo, asethe amazinga wesampula, ashintshe usayizi wamavidiyo, noma aqophe ideskithophu yekhompyutha yakho. Mayelana neyokugcina uzakwethu ukhulume nathi esikhathini esithile esedlule.

Emigqeni elandelayo sizobona izinyathelo ezidingekayo zoku faka i-FFmpeg ku-Ubuntu 18.04. Sizobona ukuthi singayifaka kanjani inguqulo ezinzile yamanje noma inguqulo yakamuva etholakalayo. Imiyalo efanayo ingasetshenziswa ku-Ubuntu 16.04 nanoma yikuphi ukusatshalaliswa okususelwe ku-Ubuntu, kufaka phakathi iLinux Mint ne-Elementary OS.

I-FFmpeg ku-Ubuntu

Faka i-FFmpeg 3.X

En los Izindawo zokugcina ezisemthethweni ze-Ubuntu singathola i-FFmpeg, futhi singayithola faka kalula ngomphathi wephakethe we-apt. Le yindlela esheshayo futhi elula yokufaka i-FFmpeg ku-Ubuntu. Noma kunjalo, inguqulo efakwe kumakhosombe kungenzeka ingabi yinguqulo yakamuva etholakalayo.

Njengoba ngibhala le migqa, inguqulo yamanje ezinzile etholakala kumakhosombe e-Ubuntu 18.04 yi-3.4.4. Uma unentshisekelo yokuba nale nguqulo, kufanele ulandele lezi zinyathelo ezilandelayo ukuyifaka ku-Ubuntu 18.04.

Sizoqala ngokuvula i-terminal (Ctrl + Alt + T). Kuyo sizobhala okulandelayo ukuvuselela uhlu lwamaphakeji atholakalayo:

sudo apt update

Ngemuva kwalokho singakwazi faka i-FFmpeg ukuthayipha umyalo olandelayo:

sudo apt install ffmpeg

Ngemuva kokufakwa, uku qinisekisa ukuthi iphakethe lifakwe kahle, singasebenzisa ukulandela umyalo. Lokhu kuzophrinta okuthile okulandelayo:

ffmpeg -version

Ukubonisana nabo bonke ama-encoders nama-decoder atholakalayo, singabhala:

ffmpeg -encoders

ffmpeg -decoders

Ngakho konke okungenhla sizobe sikufakile futhi sakuqinisekisa ukufakwa kwe-FFmpeg 3.X ohlelweni lwethu lwe-Ubuntu. Manje sesingaqala ukuyisebenzisa.

Faka i-FFmpeg 4.X

Uma sithanda faka inguqulo entshaNgemiyalo elandelayo sizokwazi ukufaka i-FFmpeg version 4.x ku-Ubuntu 18.04.

Inguqulo 4.X yale suite yesoftware ingeza inqwaba yezihlungi ezintsha, ama-encoders nama-decoder. Le nguqulo itholakala ku-PPA kaJonathon F. Izinyathelo ezingezansi zichaza ukuthi ungayifaka kanjani i-FFmpeg 4.x ku-Ubuntu 18.04.

Siqala ngokuvula i-terminal (Ctrl + Alt + T). Kuyo sizobhala okulandelayo ukufaka i-PPA edingekayo:

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

Lapho usungeze i-PPA kusistimu yakho, unga faka iphakethe elidingekayo ukuthayipha:

sudo apt install ffmpeg

Ngalokhu, uzoba nohlobo lwe-4.X olufakwe ohlelweni futhi olulungele ukusetshenziswa. Ungakwazi hlola inguqulo efakiwe ngomyalo ofanayo esiwusebenzisa ngenguqulo 3.X:

ffmpeg -version

Izibonelo ezithile

Lapho uguqula amafayela alalelwayo nevidiyo nge-FFmpeg, awudingi ukucacisa amafomethi wokufaka nawokukhipha. Ifomethi yefayela yokufaka nefomethi yokukhipha ibekwa kusuka kusandiso sefayela.

Ukube besifuna guqula ifayela levidiyo lisuke ku-mp4 liye kwi-webm, kufanele ubhale okuthile okufana nalokhu:

ffmpeg -i entradaVideo.mp4 salidaVideo.webm

Uma kwenzeka sinentshisekelo guqula ifayela le-mp3 lomsindo libe yi-ogg, imiyalo izofana nokulandelayo:

ffmpeg -i entradaAudio.mp3 salidaAudio.ogg

Lapho kuguqulwa amafayela, sizokwazi uku ucacise ama-codec esifuna ukuwasebenzisa nge -c inketho. I-codec ingaba igama lanoma iyiphi i-decoder / encoder esekelwayo.

Ukube besifuna guqula ifayela levidiyo lisuke ku-mp4 liye kwi-webm usebenzisa i-libvpx video codec ne-libvorbis audio codec. Kuzofanele sisebenzise i-oda elifana nalokhu okulandelayo:

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

Uma kwenzeka ufuna guqula ifayela lomsindo lisuke ku-mp3 liye ku-ogg encoded ne-libopus codec. Umyalo wokusebenzisa uzoba into efana nale elandelayo:

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

Imininingwane engaphezulu yokuthi ungayisebenzisa kanjani le suite yesoftware ingatholakala ukubonisana ne- imibhalo esemthethweni by SGIYA ngoMASKANDI MEDIA.
