FFmpeg inopfuura chirongwa, iri muunganidzwa wemahara software zvishandiso zvemultimedia. Nayo unogona kushandura pakati pema multimedia mafomati (odhiyo uye vhidhiyo), shandisa akasiyana macodec (ona iro libavcodec raibhurari), rekodhi, gadziridza mavhidhiyo akaora, uye zvimwe zvakawanda. Chokwadi ndechekuti ndechimwe chezvishandiso zvakasiyana-siyana zvandinoziva, uye nekutenda kune icho hwaro hwezvirongwa zvakawanda zvinozivikanwa.
Zvakanaka, FFmpeg ikozvino ine vhezheni itsva, ndiye FFmpeg 4.2 «Ada» uye inounza nhau dzinonakidza. Iwe unogona ikozvino kurodha pasi kubva pano. Iyi nyowani nhevedzano kana vhezheni ine rutsigiro rweAV1 kuburikidza ne libdav1d raibhurari, rutsigiro rweARIB STD-B24 yakavakirwa pane raibaribb24 raibhurari, rutsigiro rweHEVC 4: 4: 4 mu nvdec uye cuviddec, pamwe nekumwe kugadzirisa uye kugadzirisa kune yayo kodhi kodhi. .
Iwe zvino uchave nerutsigiro rwekushandisa iyo Clang compiler uye kuumbiridza ye CUDA tsanga, GIF paser, uye iyo libndi-newtek chikamu chabviswa. Iwe zvakare uchawana nyowani multimedia mafirita, demuers, pamusoro peavo madhisodhi ataurwa pamusoro. Iwo maraibhurari matsva anoumba FFmpeg 4.2 ikozvino 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, uye libpostproc.
Izvo zvakati, koka iwe kuti uedze ffmpeg kana iwe wanga usingazvizive uye usati wamboishandisa kare. Icho chishandiso chinotyisa. Chokwadi iwe wakamboishandisa usingazvizive mune yekushandisa kana vhidhiyo mutambo unoishandisa. Zvakare, kupedzisa chinyorwa, ndinokusiira zvimwe ffmpeg mienzaniso yekushandisa saka unogona kuzvionera kushanduka 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
Izvozvo vanoshandira gadzirisa vhidhiyo yakashatiswa nekuda kwechigadziro, chinja .wav odhiyo kuva .mp3, shandura kubva kumavhidhiyo fomati fomati kuenda avi, bvisa odhiyo odhiyo kubva muvhidhiyo, uye pfuura zvese zvekurodha mavhidhiyo (semuenzaniso kubva kuYouTube, kwete kuenda rimwe nerimwe) kune odhiyo zvichiteerana. Ndinovimba yakaringana
