FFmpeg yiyo Iprojekti yesoftware yasimahla Inako ukuvumela abasebenzisi ukuba benze isigqibo, basonge, badlulise ikhowudi, i-mux, i-demux, i-stream, icebo lokucoca ulwelo, ukusasaza iaudiyo nevidiyo, phakathi kwezinye izinto ezininzi.
Kuya kufuneka uchaze ukuba iphakheji iqulethe libavcodec , libavutil, libavformat, libavfilter, libavdevice, libswscale kunye nesampulu ye-libs enokusetyenziswa zizicelo. Kunye neffmpeg, ffserver, ffplay kunye neffprobe, yona Ingasetyenziswa ngabasebenzisi bokugqibela ngokuhambahamba, ukusasaza kunye nokudlala kwakhona.
I-FFmpeg iphuhlisiwe kwi-GNU / Linux, kodwa inokudityaniswa kwiinkqubo ezininzi zokusebenza, kubandakanya iiWindows. FFmpeg evelisa iilayibrari kunye neenkqubo ezisetyenziselwa ukuphathwa kwedatha yemultimedia.
I-FFmpeg ixhasa iifomati ezindala ukuya kwezona zininzi ngoku. Ngamafutshane, sisisombululo esipheleleyo, esinqamlezileyo sokurekhoda, ukuguqula kunye nokusasaza iaudiyo nevidiyo.
Yintoni entsha kwiFFmpeg 4.0
FFmpeg ihlaziyiwe kutshanje iza emva kweenyanga ezintandathu zoluhlu lwe-3.x, i-FFMpeg 4.0 izisa amacebo okucoca ulwelo ngokuhamba kwemethadatha kwiifomathi ze-H.264, ze-MPEG-2 kunye ne-HEVC, i-encoder yovavanyo ye-MagicYUV, i-Nvidia NVDEC ikhawuleze i-H.264, i-MPEG-1/2/4, i-HEVC, i-VC1, i-VP8 / 9 kunye ne-MJPE hwaccel decoding, kunye ne-Intel QSV ekhawulezileyo ye-MJPEG ukwenza ikhowudi.
Kwakhona kufakwe iikhowudi ezintsha zemveli kunye neekhowudi I-aptX, i-aptX HD kunye ne-SBC, kunye Inkxaso yokumisela I-VAJI MJPEG kunye ne-VP8, i-TiVo ty / ty + demuxer, i-VideoToolbox HEVC encoder kunye ne-hwaccel, inkxaso ye-E-AC-3 izakhelo ezixhomekekileyo, kunye ne-AMD AMF HEVC kunye ne-H.264 encoders.
Inkxaso yeLibreSSL Ukuphunyezwa komthombo ovulekileyo we-SSL (iZiseko zoKhuseleko eziKhuselekileyo) kunye ne-TLS (uLawulo loKhuseleko loThutho), yaphunyezwa lilayibrari ye-libtls, i-codec2 encoding kunye ne-decoding inkxaso ngethala leencwadi le-libcodec2, inkxaso ye-AV1 kwilayibrari ye-libaom kunye nenkxaso ye-Haivision SRT protocol kwilayibrari yethala leencwadi.
Ukongeza, kukho ifayile ye- Icebo lokucoca ulwelo ngevidiyo, icebo lokucoca ulwelo Isikhongozelo se-lv2, isihluzo somoya ococekileyo, isihluzo sevidiyo evulekileyo, isihluzo se-OpenCL, isihluzo se-Intel QSV esikhawulezayo, i-VAAPI ekhawulezayo ye-ProcAmp (ibhalansi yombala), i-denoise kunye neefilitha ezibukhali, icebo lokucoca ulwelo lwe-E-AC yokukhupha- isiseko se-3, ngokunjalo njengesihluzi se-hilbert somsindo.
I-FFmpeg 4.0 ilahla inkxaso yeWindows XP yokusebenza njengoko iphelelwe lixesha, yintoni ngoku eyona nguqulelo incinci ixhaswayo yiWindows Vista. Le nguqulo ikwasusa inkqubo ye-ffserver, kunye ne-ffmdec kunye ne-ffmenc demuxer kunye ne-muxer.
Uyifaka njani i-FFmpeg inguqulo ye-4.0 kwiLinux?
FFmpeg Ifakiwe kuninzi losasazo lweLinux, Nangona ingezizo zonke ezihlaziyiweyo kuhlobo lwayo olutsha, ke kuyimfuneko ukongeza indawo yokugcina eyongezelelweyo.
ukuba Kwimeko ekhethekileyo kaDebian Jessie, kufuneka ukongeza oku kulandelayo, sivula i-terminal kwaye siphumeze:
sudo sh -c 'echo "deb http://www.deb-multimedia.org jessie main non-free" >> /etc/apt/sources.list'
Sihlaziya indawo yokugcina
sudo apt-get update
Sifaka ukuxhomekeka okuthile:
sudo apt-get install deb-multimedia-keyring
Kwakhona sihlaziya kwaye sifake i-FFmpeg, ukuba usebenzisa iDebian 9 sebenzisa le miyalelo:
sudo apt-get update sudo apt-get install ffmpeg
Kwimeko yoBuntu, sinendawo yokugcina izinto esinokuzixhasa ngayo, sivula nje i-terminal kwaye siyenze.
Songeza indawo yokugcina kunye:
sudo apt-add-repository ppa:jonathonf/ffmpeg-3
Sihlaziya indawo yokugcina:
sudo apt-get update
Gqibela sifaka ngalo myalelo:
sudo apt-get install ffmpeg
Kwimeko ye-Fedora, kufuneka siphumeze umyalelo ngokuxhomekeke kuhlobo lwenkqubo yethu, oku kunokwenzeka ukuba awunayo i-rpm fusion repositories eyongezwe kwinkqubo yakho:
Fedora 26
sudo yum install http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-26.noarch.rpm sudo yum update sudo yum install ffmpeg
YeFedora 27
sudo yum install http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-27.noarch.rpm sudo yum update sudo yum install ffmpeg
Fedora 28
sudo yum install http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-28.noarch.rpm sudo yum update sudo yum install ffmpeg
Kwimeko ye I-Arch Linux kunye neziphumo esisebenza kuzo kuphela:
sudo pacman -S ffmpeg
Kwaye ngale nto sele sineyona nguqulelo yangoku yeFFmpeg efakwe kwinkqubo yethu, ngokuhamba kweeveki okanye iinyanga siza kuqala ukubona iinguqulelo ezintsha kunye nemisebenzi eyongezwe kubo bonke abahleli bevidiyo abasebenzisa iFFmpeg.
