I-FFmpeg 6.1 "I-Heaviside" ifika nenkxaso ye-Vulkan, ii-codecs, ii-decoder kunye nokunye

FFmpeg

I-FFmpeg sesona sikhokelo siphambili semultimedia

I ukukhutshwa kwenguqulelo entsha yeFFmpeg 6.1 codenamed "Heaviside", eyayilibaziseke kangangesiqingatha sonyaka ngenxa yomsebenzi oqhubekayo kwindawo yokugcina, kodwa ilapha kwaye ifika. ukuphumeza inkitha yophuculo lwenkxaso nokunye okuninzi.

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.

Iimpawu ezintsha eziphambili zeFFmpeg 6.1

Kolu guqulelo lutsha oluvezwayo, kugxininiswe ukuba i ukukwazi ukusebenzisa i Vulkan API ukuya i-hardware yevidiyo yokuguqula iifomati H264, HEVC kunye ne-AV1.

Ukongeza koku, kwiFFmpeg 6.1 a g yongezweuninzi lwenkxaso entsha, injalo imeko entsha Isifaki khowudi sefomathi yevidiyo ye-VAAPI esekwe kwi-AV1, kunye nenkxaso yokusetyenziswa kwe I-HEVC, i-VP9 kunye ne-AV1 codecs kwimilambo esekwe kwiprothokholi ye-rtmp kunye neefayile zefomathi ye-flv kunye nenkxaso eyandisiweyo ye-VAAPI kwiinkqubo zeWindows kunye nelayibrari ye-libva-win32.

Kwakhona kwiFFmpeg 6.1 i ukukwazi ukusebenzisa iiparameters ukukhawulezisa i-encoding ividiyo usebenzisa ithala leencwadi libx264, Inkxaso yomyalelo eyongeziweyo kwiiseti kunye nezihluzi ze-asethi kunye nenkxaso eyongeziweyo ye-Microsoft RLE ye-encoder yevidiyo yefomathi.

Olunye utshintsho olugqamayo kolu kukhutshwa lu iinketho ezintsha zongezwa, enye yazo "-funda_ukuqhuma_kokuqala" oko kongezwa ukuseta ixesha lokuqala lokubhafa, emva koko "-funda umda" uqala ukusebenza.

Enye kwi-ffprobe, apho "-output_format" yongezwa khona, efana no "-of" ukhetho kwaye enokusetyenziswa ukumisela ifomathi yemveliso (umzekelo ungasebenzisa ifomathi ye-json). I-schema yemveliso ye-XML iye yalungiswa ukuze ixhase izinto ezininzi ezidityaniswe nomzali omnye.

Olunye utshintsho evelele kule nguqulo intsha:

  • Ukhetho '-phezulu' luyekisiwe kwaye icebo lokucoca indawo kufuneka lisetyenziswe endaweni yalo.
  • I-ARIB STD-B24 idikhowuda yemibhalo engezantsi iphunyezwa ngokusekwe kwithala leencwadi le-libaribcaption.
  • Uluhlu olufakiweyo, i-encoder kunye ne-decoder kwizikhongozeli zemidiya kwifomathi ye-EVC.
  • Izihluzi zevidiyo ezitsha:
    umbala_vulkan-Yenza isakhelo sombala onikiweyo ngokubiza iVulkan API.
    bwdif_vulkan: yenza deinterlacing usebenzisa BWDIF algorithm iphunyezwe nge Vulkan API.
    bwdif_cuda: deinterlacing usebenzisa algorithm BWDIF, iphunyezwe ngokusekelwe CUDA API.
    nlmeans_vulkan: denoising usebenzisa non-local iindlela algorithm iphunyezwe usebenzisa Vulkan API.
    xfade_vulkan: Ukuphunyezwa kwesiphumo sokuphela kusetyenziswa iVulkan API.
    I-Zoneplate-Yenza itafile yovavanyo yevidiyo esekwe kwibhodi yendawo yeFresnel
  • Izihluzi zesandi esitsha:
    arls: Isebenzisa izikweri eziphinda-phindayo ukuqikelela iparameters zolandelelwano lwesandi ukuya kwenye.
    afireqsrc: yenza i-FIR (isihluzi sempendulo ye-impulse esiphelo) isilinganisi.
    apsnr: ilinganisa umgangatho womqondiso ukuya kwingxolo.
    asisdr: ilinganisa inqanaba lokuphazamiseka komqondiso.

Kwabo banomdla wokukwazi ukufunda ngakumbi malunga nokukhululwa okutsha okanye bafunde ngakumbi malunga neFFmpeg, banokujongana neenkcukacha kwi. ukulandela ikhonkco.

Khuphela kwaye ufumane iFFmpeg 6.1

Ekugqibeleni, ipheKwabo bafuna ukufaka okanye ukuhlaziya iFFmpeg 6.1 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 dnf install ffmpeg

Kwaye kwimeko yabo bangabasebenzisi beArch Linux, iManjaro okanye nayiphi na enye into ephuma kwiArch Linux, kwanele ukwenza lo myalelo ulandelayo:

sudo pacman -S ffmpeg
