Emva kweenyanga ezintandathu zophuhliso ukukhutshwa kwenguqulelo entsha yephakheji yemultimedia eyaziwayo FFmpeg 5.1 yabhengezwa, equka isethi yezicelo kunye nengqokelela yeelayibrari zokusebenza kwiifomathi ezahlukeneyo zemultimedia (ukurekhoda, ukuguqulwa kunye nokuguqulwa kweefomathi zeaudio kunye nevidiyo).
Kulabo abangaqhelekanga ngeFFmpeg kufuneka bazi ukuba kunjalo 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.
Iimpawu ezintsha eziphambili zeFFmpeg 5.1
Kule nguqulo entsha ye-FFmpeg 5.1 evezwayo, igxininiswe ukuba inkxaso eyongeziweyo ye-IPFS inkqubo yeefayile ezinatyisiweyo kunye neprotocol esetyenziswa nayo ukubophelela iidilesi ze-IPNS ezisisigxina, kunye nenkxaso yefomathi yomfanekiso we-QOI kunye nenkxaso ye-PHM (Portable Half float Map) ifomathi yomfanekiso.
Olunye utshintsho olugqamayo kolu guqulelo lutsha luboniswayo lolo kuphunyezwe ukukwazi ukusebenzisa i-VDPAU API (ukwenziwa kweekhowudi zevidiyo kunye nonikezelo) ukwenzela ukukhawuleziswa kweekhowudi zevidiyo kwifomathi ye-AV1.
Ngaphezu koko, nayo yongezwe "-o" ukhetho kwi-ffprobe into eluncedo kwimveliso echaziweyo endaweni yemveliso eqhelekileyo, kwakhona yongeza ii-decoders ezintsha: i-DFPWM, i-Vizrt Binary Image, yongeza ii-encoders ezintsha: i-pcm-bluray, i-DFPWM, i-Vizrt Binary Image, i-media container packers (i-muxer) eyongeziweyo: i-DFPWM kunye nokongeza i-media container unpackers (demuxer): DFPWM.
Kwelinye icala, kuyakhankanywa ukuba Ndiyazi ukuba isusiwe inkxaso yojongano lwelifa ye-XvMC yokwenziwa kweekhowuwudi zevidiyo.
Ngokuphathelele izihluzi zevidiyo ezintsha yongezwe kolu guqulelo lutsha:
- I-SITI: Yenza izibalo ze-SI (uLwazi lweSithuba) kunye ne-TI (IiNkcukacha zeThutyana) iimpawu zevidiyo.
- I-avsynctest -Yenza iitshekhi ze-audio kunye nevidiyo yokuvumelanisa.
- impendulo: phinda uqondise izakhelo ezisikiweyo kwesinye isihluzi kwaye emva koko udibanise isiphumo kunye nevidiyo yoqobo.
- pixelize: yenza ipixelization yevidiyo.
- Imephu yombala: imbonakalo yemibala yezinye iividiyo.
- itshathi yombala: yenza itshathi yombala.
- phinda-phinda-phinda amaxabiso epixel yevidiyo yokuqala ngeepixels zevidiyo yesibini.
- pgs_frame_merge – Idibanisa iisegmenti ze-PGS zesihlokwana kwipakethi enye (umsinga kancinci).
- blurdetect – Khangela izakhelo eziluzizi.
- remap_opencl : yenza pixel kwakhona.
- chromakey_cuda - kukuphunyezwa kwechromakey esebenzisa iCUDA API ukukhawulezisa.
Kwaye kwe izihluzi zesandi ezitsha:
incoko: Ukuveliswa kwesandi esirhangqileyo (3.0) ukusuka kwisitiriyo, ngokugqithiselwa kwitshaneli esembindini yesandi seengxoxo zelizwi ezikhoyo kuzo zombini iitshaneli zestereo.
i-tiltshelf : inyusa / inciphisa iifrikhwensi eziphezulu okanye ezisezantsi.
i-virtualbass - Ivelisa itshaneli eyongezelelweyo ye-bass esekelwe kwidatha evela kumajelo e-stereo.
Kwabo banomdla wokukwazi ukufunda ngakumbi malunga nokukhululwa okutsha okanye bafunde ngakumbi malunga neFFmpeg, banokujongana neenkcukacha kwi. ukulandela ikhonkco.
Khuphela kwaye ufumane iFFmpeg 5.1
Ekugqibeleni, ipheKwabo bafuna ukufaka okanye ukuhlaziya iFFmpeg 5.1 Kuya kufuneka uyazi ukuba le phakheji ifumaneka kunikezelo oluninzi lweLinux okanye ukuba uyathanda, unokukhuphela ikhowudi yemvelaphi yayo ukuze uyihlanganise. kwikhonkco elingezantsi.
Kwaye ukwenza ufakelo olusuka kwikhowudi yemvelaphi, kwanele ukwenza iskripthi esele saziwa:
./configure make make install
Kwimeko yabo bangabasebenzisi baka-Ubuntu, iDebian okanye nayiphi na enye into ephuma kolu sasazo, vula ngokulula i-terminal kwaye wenze lo myalelo ulandelayo kuyo:
sudo apt install ffmpeg
Ngelixa ukwimeko yeFedora, umyalelo wokuphumeza lo ulandelayo:
sudo install ffmpeg
Kwaye kwimeko yabo bangabasebenzisi beArch Linux, iManjaro okanye nayiphi na enye into ephuma kwiArch Linux, kwanele ukwenza lo myalelo ulandelayo:
