Emva kweenyanga ezisithoba zophuhliso kwagqitywa uhlobo olutsha lwephakheji yemultimedia yeFFmpeg 4.2, uguqulelo esele lukhona. I-FFmpeg 4.2 kubandakanya ukulungiswa kwe-bug kunye nezinto ezintsha eziphucula ukusebenza kwayo.
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.
I-FFmpeg iphuhlisiwe kwi-GNU / Linux, kodwa inokudityaniswa kwiinkqubo ezininzi zokusebenza, kubandakanya iiWindows. FFmpeg evelisa iilayibrari kunye neenkqubo ezisetyenziselwa ukuphathwa kwedatha yemultimedia.
Iimpawu ezintsha eziphambili zeFFmpeg 4.2
Ngokufika kwale nguqulo intsha yeFFmpeg ezahlukeneyo inkxaso ziye zongezwa ngokuba Singagqamisa inkxaso ephunyeziweyo ukumisela ifomathi ye-AV1 usebenzisa enye i-dav1d decoder ephuculwe yiprojekthi yeVidiyoLAN kunye neFFmpeg. I-Dav1d ijolise ekufezekiseni owona msebenzi uphezulu wokumisela kunye nokuqinisekisa ukusebenza okuphezulu okufundwayo.
Kananjalo nenkxaso yokumisela umxholo we-HEVC 4: 4: 4 usebenzisa i-NVIDIA nvdec kunye ne-cuviddec iinjini zokukhawulezisa izixhobo, kunye nokusetyenziswa kwe-VDPAU (Ukucaciswa kweVidiyo kunye neNgcaciso) ye-API.
Isiqulatho seMedia Media songezwa kwakhona (demuxer) dhav, hcom kwaye icacile, KUX kunye ne-IFV kunye ne-PCM-DVD, VP4, hymt, hcom, ARBC, agm kunye ne-lscr encoders.
Kwi-mov media packer packer, ukurekhoda umkhondo kunikezelwa ngaphandle kwenkcazo yolwimi olucacileyo (ngaphambili, ulwimi olungagqibekanga yayingesiNgesi).
Olunye uhlobo lwenguqulelo entsha yeFFmpeg 4.2 yile ukongezwa kweefilitha ezintsha, zezi:
- asr: ukuqondwa kwentetho ngokuzenzekelayo nge-PocketSphinx injini
- I-Drain: isusa imvula kwividiyo isebenzisa i-RESCAN inkqubo yenethiwekhi esekwe kumatshini yokufunda kunye neemodeli ezilungele ukusetyenziswa
- ukubanda: Ukuzimisela ukungabikho kotshintsho kwividiyo (ngaphandle kokutshintsha ixesha elithile lomfanekiso)
- i-tpad: yongeza izakhelo ezongezelelweyo ekuqaleni okanye esiphelweni sevidiyo
- Uncedo: ukuqaqambisa ukukhanya kunye nezinto ezenziwe ngombala (ichaphaza elikhanyayo kunye nomnyama) kwividiyo
- chromashift / rgbashift: Ukufuduswa kwezinto zepikseli yemibala ethe tye ngokuthe nkqo
- yinyani_core: ifumana umjelo we-TrueHD osisiseko, ilahla imethadatha ye-ATMOS;
- NONE Ukuncitshiswa kwengxolo ye-broadband kumsinga wesandi usebenzisa i-algorithm engeyiyo eyasekhaya
- imaskfun: yenza imaski esekwe kwividiyo yegalelo
- AV1 : ukwahlula isakhelo ngokulandelelana kwe-AV1
- lag fun: icothisa utshintsho lombala lweephikseli ezimnyama (yonyusa ixesha lokubonisa lokuqaqamba okuqaqambileyo)
- uqeqesho: ukunqunyulwa okuthambileyo kwesandi (ukuthoba ngokuthe ngcembe kwesilinganiselo endaweni yokuphazamiseka okungxamisekileyo komqondiso)
- umbala: ukususwa kolwazi malunga nayo yonke imibala ye-RGB ngaphandle kwaleyo ichaziweyo
- xmedian: imephu yokuhlangana okumaphakathi kweephikseli zeevidiyo ezininzi zokufaka
- indawo yokubonisa: eguqula isandi sestiriyo sibe yividiyo, ebonisa unxibelelwano lwendawo phakathi kwamajelo amabini odiyo
- Isigqibo: Ukuphelisa ukugqwethwa ngenxa yemakrofoni esemgangathweni ongalunganga okanye uxinzelelo olugqithisileyo lwesandi ngexesha lokurekhodwa kwelizwi (ishenxisa isandi ebhankini).
Olunye utshintsho olunokuqaqanjiswa:
- Ukongezwa kwesakhono sokusebenzisa uClang ukwenza iifayile zeCUDA
- Ulwakhiwo lubandakanya isihlalutyo somfanekiso kwifomathi yeGIF
- Yongezwe inkxaso ye-ARIB STD-B24 engezantsi (iiProfayili A kunye no-C) ezisetyenziswa kwi-MPEG-2 TS yokusasaza. Inkxaso iphunyezwa ngokusebenzisa ilayibrari ye-libaribb24;
- Ithala leencwadi le-libndi-newtek lisusiwe.
Okokugqibela, kwabo bafuna ukufaka okanye ukuhlaziya i-FFmpeg, kufuneka bazi ukuba le phakheji ifumaneka kuninzi lweLinux okanye ukuba bakhetha banokuyikhuphela ikhowudi yemithombo yokuhlanganisa kwikhonkco elingezantsi.
