I-FFmpeg ingaphezu kohlelo, iqoqo lamathuluzi esoftware wamahhala wemultimedia. Ngayo ungaguqula phakathi kwamafomethi e-multimedia ahlukahlukene (alalelwayo nevidiyo), usebenzise ama-codec ahlukile (bheka umtapo wolwazi we-libavcodec), urekhode, ulungise amavidiyo akhohlakele, nokunye okuningi. Iqiniso ukuthi ngelinye lamathuluzi ahlukahlukene kakhulu engiwaziyo, futhi ngenxa yalokho kuyisisekelo sezinhlelo eziningi ezaziwayo.
Yebo, i-FFmpeg manje inenguqulo entsha, yiyona FFmpeg 4.2 «Ada» futhi uletha izindaba ezithakazelisayo. Manje usungayilanda kusuka lapha. Lolu chungechunge olusha noma inguqulo inokwesekwa kwe-AV1 ngomtapo wezincwadi we-libdav1d, ukuxhaswa kwe-ARIB STD-B24 ngokususelwa kumtapo wezincwadi we-libaribb24, ukusekelwa kwe-HEVC 4: 4: 4 ku-nvdec naku-cuviddec, ngokungeziwe ekulungisweni nasekuthuthukisweni kwekhodi yayo yomthombo .
Manje uzoba nokusekelwa kokusebenzisa i-Clang compiler nokuhlanganisela i- Izinhlamvu ze-CUDA, i-GIF paser, nengxenye ye-libndi-newtek isusiwe. Uzothola nezihlungi ezintsha ze-multimedia, ama-demuers, ngaphezu kwalawo ma-decoder okukhulunywe ngenhla. Imitapo yolwazi emisha eyakha i-FFmpeg 4.2 manje seyi-libavutil 56.31.100, libavcodec 58.54.100, libavformat 58.29.100, libavdevice 58.8.100, libavfilter 7.57.100, libswscale 5.5.100, libswresample 3.5.100, kanye libpostproc 55.5.100. .
Lokho kusho, ukumeme ukuthi uzame i-ffmpeg uma ubungazi ngakho futhi ungakaze uyisebenzise ngaphambilini. Kuyithuluzi elimangalisayo. Impela uyisebenzisile ngaphandle kokuyibona kuhlelo lokusebenza noma umdlalo wevidiyo oyisebenzisayo. Futhi, ukuqedela i-athikili, ngikushiyela okunye izibonelo zokusetshenziswa kwe-ffmpeg ukuze uzibonele ukusebenza kwayo okuhlukahlukene:
ffmpeg -i video-corrupto.mp4 -c copy video-reparado.mp4
ffmpeg -i video.wav -vn -ar 44100 -ac 2 -b:a 192k audio.mp3
ffmpeg -i video.mkv nuevovideo.avi
ffmpeg -i video.flv -acodec libmp3lame video.mp3
for vid in *.mp4; do ffmpeg -i "$vid" -vn -acodec libmp3lame "${vid%.mp4}.mp3"; done
Que basebenzela lungisa ividiyo ekhohlakele ngenxa yesitsha, guqula i-.wav audio iye ku-mp3, guqula kusuka kwifomethi yevidiyo ye-mkv iye ku-avi, khipha ithrekhi yomsindo kuvidiyo, futhi udlulise konke okulandwayo kwevidiyo (ngokwesibonelo kusuka ku-Youtube, hhayi ukuhamba ngamunye ngamunye) kumsindo ngokulandelana . Ngiyethemba ukuthi ilungile
