Mushure memwedzi mipfumbamwe yekuvandudza shanduro nyowani yeiyo multimedia package FFmpeg 4.2 yakaburitswa, vhezheni iyo yatovepo. FFmpeg 4.2 inosanganisira kugadzirisa zvipuka uye zvinhu zvitsva zvinovandudza mashandiro ayo.
Kune avo vasina kujairana neFFmpeg vanofanira kuziva kuti izvi ndizvo yemahara software chirongwa Iyo inogona iyo inobvumidza vashandisi kusarudza, encode, transcode, mux, demux, kuyerera, kusefa, kutenderera odhiyo uye vhidhiyo, pakati pezvimwe zvinhu zvakawanda zvimwe.
Izvo zvakakoshawo kutaura kuti iyo package ine libavcodec , libavutil, libavformat, libavfilter, libavdevice, libswscale uye libswresample iyo inogona kushandiswa nemaapplication. Zvakare neffmpeg, ffserver, ffplay uye ffprobe, iyo inogona kushandiswa nevashandisi vekupedzisira pakutapudza, kutenderera uye kutamba.
FFmpeg inogadzirwa paGNU / Linux, asi inogona kunyorwa pane mazhinji masisitimu anoshanda, kusanganisira Windows. FFmpeg inoburitsa maraibhurari uye zvirongwa izvo zvinoshandiswa kune multimedia dhata yekumanikidza.
Main nyowani maficha eFFmpeg 4.2
Nekusvika kweiyi nyowani vhezheni yeFFmpeg zvitsigiso zvakasiyana siyana zvakawedzerwa izvo isu tinogona kusimbisa rutsigiro rwunoshandiswa kusimbisa fomati yeAV1 uchishandisa imwe nzira dav1d decoder yakagadzirwa neVideoLAN uye FFmpeg mapurojekiti. Dav1d yakanangana nekuwana iyo yepamusoro inogoneka yekumisikidza kuita uye kuona yepamusoro mhando multithreaded mashandiro.
Zvakare nerutsigiro rwekunongedza HEVC 4: 4: 4 zvemukati uchishandisa iyo NVIDIA nvdec uye cuviddec michina yekumhanyisa injini, pamwe nekushandiswa kweVDPAU (Vhidhiyo Kududzira uye Mharidzo) API.
Media Container Unpacks Zvakawedzerwa (demuxer) dhav, hcom uye yakajeka, KUX uye IFV uye PCM-DVD, VP4, hymt, hcom, ARBC, agm uye lscr encoders.
Mu mov media media packer, kurekodha kunopihwa pasina tsananguro yemutauro yakajeka (kare, mutauro wekutanga waive Chirungu).
Imwe nzira itsva yeiyi nyowani vhezheni yeFFmpeg 4.2 iri kuwedzerwa mafirita matsva, ayo ari:
- asr: otomatiki kutaura kunozivikanwa nePocketSphinx injini
- derail: inobvisa mvura kubva muvhidhiyo uchishandisa RESCAN neural network-yakavakirwa muchina wekudzidza muchina uye kunze-kwe-mubhokisi mamodheru
- freezedetect: kutsunga kwekushayikwa kweshanduko muvhidhiyo (pasina kuchinja imwe nguva yemufananidzo)
- t-pad: wedzera mamwe mafuremu pakutanga kana kumagumo kwerukova rwevhidhiyo
- chigunwe: kutsvedza kupenya uye neruvara rwezvigadzirwa (dot flash uye muraraungu) muvhidhiyo
- chromashift / rgbashift: kusuduruka kwepikisheni kara yezvinhu yakatwasuka uye yakatwasuka
- truehd_core: inowana iriko pasi pechokwadi TrueHD rwizi, ichirasa ATMOS metadata;
- anlmdn: kudzvinyirira ruzha rwe Broadband murukova ruzha uchishandisa isiri-yemuno avhareji algorithm
- maskfun: gadzira mask zvichibva paiyo yekuisa vhidhiyo
- AV1 : furemu kupatsanura muAV1 kuteedzana
- lag mafaro: inononoka shanduko yemavara yemapikisheni erima (inowedzera nguva yekuratidzira yezvakanaka zvinojekesa)
- asoftclip: kutapira kutapudza kwezwi (zvishoma nezvishoma kuderedzwa kweiyo amplitude panzvimbo pekukanganisa kwechimbichimbi kwechiratidzo)
- colorhold: kubviswa kweruzivo nezve ese RGB mavara kunze kweiyo yakatsanangurwa
- xmedian: kugadzira mepakati penzira yemapikisheni emavhidhiyo akawanda ekuisa
- showpatial: inoshandura ruzha rwe stereo kuita vhidhiyo, ichiratidza kudyidzana kwepakati pakati penzira mbiri dzekuterera
- deeser: Inobvisa kutsauka nekuda kwemakrofoni emhando yepamusoro kana kudzvanyirira ruzha panguva yekurekodha izwi (inobvisa mhedzisiro yezwi mubhangi).
Yeimwe shanduko dzinogona kusimbiswa:
- Wakawedzera kugona kushandisa Clang kuumbiridza maCUDA mafaera
- Iyo dhizaini inosanganisira mufananidzo muongorori muGIF fomati
- Wakawedzera rutsigiro rweARIB STD-B24 manyorerwo (Maprofayiri A uye C) anoshandiswa muMPEG-2 TS kutenderera. Tsigiro inoitwa nekushandisa libaribb24 raibhurari;
- Raibhurari-newtek raibhurari yabviswa.
Chekupedzisira, kune avo vanoda kuisa kana kugadzirisa FFmpeg, vanofanirwa kuziva kuti pasuru iyi inowanikwa mune akawanda maLinux ekuparadzira kana kana vachida vanogona kurodha pasi rekodhi yekodhi yekubatanidza kubva pane iyi link iripazasi.
