I-FFmpeg ingaphezulu kwenkqubo, yingqokelela yezixhobo zesoftware yasimahla yemultimedia. Ngayo unokuguqula phakathi kweefomathi zemultimedia ezahlukeneyo (iaudiyo kunye nevidiyo), sebenzisa iikhowudi ezahlukeneyo (jonga ilayibrari ye-libavcodec), urekhode, ulungise iividiyo ezikhohlakeleyo, nokunye okuninzi. Inyaniso kukuba sesinye sezixhobo ezibhetyebhetye ndiyazazi, kwaye enkosi kuloo nto sisiseko seenkqubo ezininzi ezaziwayo.
Ewe, iFFmpeg ngoku inenguqulo entsha, yiFFmpeg 4.2 «Ada» kwaye izisa iindaba ezinomdla. Ngoku unokuyikhuphela ukusuka apha. Olu luhlu lutsha okanye ingxelo inenkxaso ye-AV1 kwilayibrari ye-libdav1d, inkxaso ye-ARIB STD-B24 esekwe kwilayibrari ye-libaribb24, inkxaso ye-HEVC 4: 4: 4 kwi-nvdec nakwi-cuviddec, ukongeza kulungiso oluthile, kunye nokuphuculwa komthombo wayo ikhowudi.
Ngoku uya kuba nenkxaso yokusebenzisa i-Clang compiler kunye nokuqulunqa Iinkozo zeCUDA, i-GIF paser, kwaye icandelo le-libndi-newtek lisusiwe. Uyakufumana kwakhona izihluzi ezitsha zemultimedia, ii-demuers, ukongeza kwezi khowudi zichazwe apha ngasentla. Amathala eencwadi amatsha enza iFFmpeg 4.2 ngoku 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, kunye libpostproc 55.5.100. .
Oko kwathiwa, mema ukuba uzame ffmpeg ukuba ubungazi ngayo kwaye khange uyisebenzise ngaphambili. Isixhobo esihle. Ngokuqinisekileyo uyisebenzisile ngaphandle kokuyiqonda kwisicelo okanye kumdlalo wevidiyo oyisebenzisayo. Kwakhona, ukugqiba inqaku, ndikushiyela ezinye Imizekelo yokusetyenziswa kwefmpmp ukuze ubone ngokwakho ukuguquguquka kwayo:
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
ukuba basebenzela Ukulungiswa kwevidiyo kumoshakele ngenxa yesikhongozeli, ukuguqula iaudi audio ukuya kwi-mp3, ukuguqula ukusuka kwifomathi yevidiyo ye-mkv ukuya kwi-avi, ukukhupha umkhondo weaudiyo kwividiyo, kwaye udlulise konke ukhuphelo lwevidiyo (umzekelo kwiYouTube, ungahambi nganye nganye) kwisandi ngokulandelelana . Ndiyathemba ukuba ilungile
