Ngemuva kwezinyanga eziyisithupha zentuthuko ukukhishwa kwenguqulo entsha yephakheji ye-multimedia ethandwayo i-FFmpeg 5.1 imenyezelwe, okufaka isethi yezinhlelo zokusebenza kanye neqoqo lemitapo yolwazi yokusebenza kumafomethi we-multimedia (ukurekhoda, ukuguqulwa nokuqoshwa kwamafomethi omsindo nevidiyo).
Kulabo abangajwayele i-FFmpeg kufanele bazi ukuthi lokhu iphrojekthi yesoftware yamahhala It can that allows users to decode, encode, transcode, mux, demux, stream, filter, streaming audio and video, phakathi kwezinye izinto eziningi.
Kuyafaneleka futhi ukusho ukuthi iphakheji iqukethe libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale kanye ne-libswresample engasetshenziswa ngezinhlelo zokusebenza. Kanye ne-ffmpeg, ffserver, ffplay ne-ffprobe, okuyi ingasetshenziswa ngabasebenzisi bokugcina ngokufaka ikhodi, ukusakaza nokudlala.
Izici ezintsha eziyinhloko zeFFmpeg 5.1
Kule nguqulo entsha ye-FFmpeg 5.1 eyethulwa, kugqanyiswe ukuthi ukwesekwa okwengeziwe kwesistimu yefayela ehlukaniselwe i-IPFS kanye nephrothokholi esetshenziswa nayo ukuhlanganisa amakheli e-IPNS angunaphakade, kanye nokusekelwa kwefomethi yesithombe se-QOI kanye nosekelo lwefomethi yesithombe se-PHM (Portable Half float Map).
Olunye ushintsho olugqamayo kule nguqulo entsha eyethulwa yileso yenze ikhono lokusebenzisa i-VDPAU API (ukuhlelwa kwevidiyo nokwethulwa) kokusheshiswa kwehadiwe ukuqoshwa kwevidiyo ngefomethi ye-AV1.
Ngaphezu kwalokho, futhi yengeze inketho ethi "-o" ku-ffprobe insiza yokukhipha ifayela elishiwo esikhundleni sokuphuma okujwayelekile, futhi yengeze amadekhoda amasha: i-DFPWM, i-Vizrt Binary Image, yengeza izifaki khodi ezintsha: i-pcm-bluray, i-DFPWM, i-Vizrt Binary Image, ifaka amapaki esiqukathi semidiya (muxer): i-DFPWM futhi yengeza izikhiphi zesitsha semidiya (demuxer ): DFPWM.
Ngakolunye uhlangothi, kushiwo futhi lokho Ngiyazi ukususa usekelo lwesixhumi esibonakalayo sefa yokuqopha ividiyo yehadiwe ye-XvMC.
Ngokuqondene ne izihlungi ezintsha zevidiyo kwengezwe kule nguqulo entsha:
- I-SITI: Yenza izibalo zezimpawu zekhwalithi yevidiyo ye-SI (Spatial Information) kanye ne-TI (Temporal Information).
- I-avsynctest - Yenza amasheke okuvumelanisa umsindo nevidiyo.
- impendulo: qondisa kabusha amafreyimu anqanyuliwe kwesinye isihlungi bese uhlanganisa umphumela nevidiyo yoqobo.
- pixelize: yenza i-pixelization yevidiyo.
- colormap: ukubonakaliswa kwemibala yamanye amavidiyo.
- colorchart: ikhiqiza ishadi lombala.
- phindaphinda - Iphindaphinda amanani we-pixel wevidiyo yokuqala ngamaphikseli wevidiyo yesibili.
- pgs_frame_merge - Ihlanganisa izingxenye zemibhalo engezansi ye-PGS ibe yiphakethe elilodwa (ukusakaza kancane).
- blurdetect - Thola amafreyimu afiphele.
- remap_opencl : yenza ukumepha kabusha kwe-pixel.
- I-chromakey_cuda - ukusetshenziswa kwe-chromakey esebenzisa i-CUDA API ukusheshisa.
Futhi kwe izihlungi zomsindo ezintsha:
inkhulumomphendvulwano: ukukhiqizwa komsindo ozungezayo (3.0) usuka ku-stereo, ngokudluliselwa esiteshini esimaphakathi somsindo wezingxoxo zezwi ezikhona kuzo zombili iziteshi zesitiriyo.
i-tiltshelf : inyusa/inciphisa amaza aphezulu noma aphansi.
i-virtualbass - Ikhiqiza enye ishaneli ye-bass ngokusekelwe kudatha evela eziteshini ze-stereo.
Kulabo abanesifiso sokwazi ukufunda okwengeziwe ngalokhu kukhululwa okusha noma ukufunda okwengeziwe nge-FFmpeg, bangathintana nemininingwane ku- isixhumanisi esilandelayo.
Landa futhi uthole i-FFmpeg 5.1
Ekugcineni, pKulabo abafuna ukufaka noma ukuvuselela i-FFmpeg 5.1 Kufanele wazi ukuthi le phakheji itholakala ekusakazweni okuningi kwe-Linux noma uma uthanda, ungalanda ikhodi yayo yomthombo ukuze ihlanganiswe. kusuka kusixhumanisi esingezansi.
Futhi ukwenza ukufakwa kusuka kukhodi yomthombo, kwanele ukwenza iskripthi esivele saziwa:
./configure make make install
Endabeni yalabo abangabasebenzisi be-Ubuntu, i-Debian noma enye into ephuma kulokhu kusatshalaliswa, vele uvule i-terminal bese ukhipha umyalo olandelayo kuyo:
sudo apt install ffmpeg
Ngenkathi ku-Fedora, umyalo wokukhipha ulandelayo:
sudo install ffmpeg
Futhi esimweni salabo abangabasebenzisi be-Arch Linux, i-Manjaro nanoma iyiphi enye i-Arch Linux, kwanele ukwenza lo myalo olandelayo:
sudo pacman -S ffmpeg
