Kadib toban bilood oo shaqo adag ah oo diirada lagu saaray soo saarista nooca cusub ee xirmada caanka ah ee caanka ah ee loo yaqaan 'multimedia' "FFmpeg 4.3" horumariyayaasheeda ku dhawaaqday daah-furkeeda iyo helitaankeeda dadweynaha guud.
Noocaan cusub ee FFmpeg 4.3 waxaa kujira isbadalo badan, oo laga yaabo inay tahay waxa ugu muhiimsan dhamaantood waa taageerada lagu daray Vulkan graphical API, kaas oo la socda waxyaabo badan oo cusub.
Kuwa aan ka warqabin FFmpeg, waa inaad ogaataa taas waa xirmo warbaahin badan si ballaaran loo yaqaan oo loo isticmaalo tiro badan oo codsiyo ah, ilaa waxaa ku jira noocyada codsiyada iyo uruurinta maktabadaha loogu talagalay hawlgallada qaabab kala duwan oo multimedia ah (duubista, beddelka iyo kelmadaha qaabab maqal iyo muuqaal ah).
Xirmada waxaa loo qaybiyaa liisamada LGPL iyo GPL, iyo horumarinta FFmpeg waxaa wada fuliya mashruuca MPlayer.
Astaamaha ugu muhiimsan ee cusub ee FFmpeg 4.3
Sida lagu sheegay bilowgii, ugubnimada ugu weyn ee nuucaan cusub ayaa ah ku darey taageerada Vulkan graphical API, laakiin taasi sidoo kale waxay la socotaa isbeddelo kale oo lagu xusay ogeysiiska in, loogu talagalay Linux, waxaa la hirgeliyaa koodhadh isticmaalaya matoorada AMD AMF / VCE dardargelinta iyo sidoo kale xulashooyinka miirayaasha caadiga ah avgblur_vulkan, overlay_vulkan, scale_vulkan, iyo chromaber_vulkan.
VDPAU (Muujinta Video iyo Soo Bandhigida) API waxaa loo isticmaali karaa dardargelinta qalabka ee VP9 video processing.
Taas ka sokow waxay ku dartay awood u lahaanshaha codeynta AV1 video adoo adeegsanaya maktabada librav1e, kuna qoran Rust oo ay soo saareen bulshooyinka Xiph iyo Mozilla.
Ku sii wadida hagaajinta Linux, sidoo kale waa la muujiyay kala guur ayaa laga sameeyay server-ka qaab-dhismeedka loogu talagalay tafatirka aan tooska ahayn ee fiidiyoowyada AvxSynth, oo ku jirtay xaalad cidla ah 5 sano, ilaa laanta hadda ee AviSynth +.
Halka guud ahaan loogu talagalay weelasha warbaahinta ee mp4, taageerada loogu talagalay Koodhadhka codka badan ee kanaalka badan HD run ah lumis la'aan iyo koodh loogu talagalay dhawaaq saddex-geesood ah oo ah MPEG-H 3D.
Intaa waxaa dheer, waan heli karnaa decoders cusub ayaa lagu daray, kuwaas oo: PFM, IMM5, Sipro ACELP.KELVIN, mvdv, mvha, mv30, NotchLC, Argonaut Games ADPCM, Rayman 2 ADPCM, Simon & Schuster Interactive ADPCM, High Voltage Software ADPCM, ADPCM IMA MTF, CDToons, Siren, DERF DF.
Xirmada konteenarrada loo yaqaan 'streamhash (muxer)' ayaa lagu daray awoodna u leh inay ku xirxirto pcm iyo pgs aaladaha m2ts.
Waxyaalaha lagu rakibo qalabka konteenarada lagu daro (demuxer): AV1 oo lagu kordhiyay App B, Argonaut Games ASF, Real War KVAG, Rayman 2 APM, LEGO Racers ALP (.tun iyo .pcm), FWSE, DERF, CRI HCA, Pro Pinball Series Soundbank.
Isbedelada kale ee muuqda:
- Taageero dheeraad ah loogu daray borotokoolka ZeroMQ iyo RabbitMQ (AMQP 0-9-1).
- Qaab dhismeedka waxaa ku jira falanqeeye sawir qaab WebP ah.
- MJPEG iyo VP9 decoders ayaa la hirgeliyay, iyadoo la adeegsanayo habka xawaaraha qalabka Intel QSV (Quick Sync Video), iyo sidoo kale Intel QSV-based VP9 encoder.
- Taageero dheereyn ah oo loogu talagalay qaababka cinwaan hoosaadka cinwaanka cinwaanka ah ee 3GPP.
- Lagu daray encoder ku qabanaya Microsoft Media Foundation API.
- Lagu daray ADPCM encoder loogu talagalay xogta maqalka ee loo isticmaalo ciyaaraha ay wadaagaan Simon & Schuster Interactive.
Shaandheeyeyaasha cusub ee lagu daray, kuwa soo socda ayaa istaaga:
- v360 - U beddelo fiidiyowyo 360 digrii ah qaabab kala duwan.
- duub: wuxuu si duudduub ah ama toos ah ugu duubayaa fiidiyaha xawaare gaar ah;
- arnndn - shaandhada xakamaynta buuqa hadalka iyadoo la adeegsanayo shabakad neerfaha soo noqnoqota;
- maskedmin iyo maskedmax - ku milmaan laba fiidiyoow oo fiidiyoow ah oo ku saleysan kala duwanaanta durdurka saddexaad;
- dhexdhexaad ah - Miiraha xakamaynta buuqa oo doorta pixel-ka dhexe ee leydi la mid ah kan ku habboon.
Finalmente kuwa doonaya inay wax badan ka ogaadaan ku saabsan sii deynta cusub, waxaad ka eegi kartaa isbedelka buuxa xiriirkan.
Iyadoo kuwa doonaya inay rakibaan ama cusbooneysiiyaan laga bilaabo FFmpeg waa inaad ogaataa in xirmadan laga helo inta badan qeybinta Linux ama haddii aad doorbideyso waxaad kala soo bixi kartaa koodhkeeda isha ee isku duwidda ka soo xiriir khadkan hoose.
