Toban bilood oo horumar ah ka dib sii deynta nooca cusub ee FFmpeg 5.0 ayaa lagu dhawaaqay, oo ay ku jiraan codsiyo iyo ururin maktabado loogu talagalay hawlgallada qaabab kala duwan oo warbaahin ah (duubista, beddelidda iyo dejinta qaababka maqalka iyo muuqaalka).
Isbeddelka weyn ee lambarka nooca waxaa sabab u ah isbeddelada API ee muhiimka ah iyo u gudubka nidaamka jiilka cusub ee sii deynta, marka loo eego sii daayo cusub oo waaweyn la samayn doono hal mar sannadkii, iyo sii dayn taageero waqti dheer - hal mar labadii sanaba mar. FFmpeg 5.0 waxay noqon doontaa nooca ugu horreeya ee LTS ee mashruuca.
Astaamaha ugu muhiimsan ee cusub ee FFmpeg 5.0
Qaabkan cusub nadiifinta muhiimka ah ee API-yadii hore ee codaynta iyo dejinta, iyo sidoo kale u gudubka N: M API-ga cusub, kaas oo bixisa hal barnaamij oo barnaamij ah oo maqal iyo muuqaal ah, iyo sidoo kale codecs gaar ah oo loogu talagalay gelinta iyo durdurrada wax soo saarka.
Sidoo kale waxaa la sheegay in dhammaan API-yadii hore loo calaamadeeyay laga saaray la jaray oo lagu daray API cusub filtarrada bitstream-ka.
Taas ka sokow, lagu daray qaabab iyo codecs gaar ahBaakadaha Warbaahintu hadda ma dhex galaan macnaha guud ee codeeyaha. API-yada la saaray ee loogu talagalay diiwaan gelinta koodka iyo qaababka: dhammaan qaababka hadda mar walba waa la diiwaan-galiyay.
Lagu daray taageerada naqshadda LoongArch ee loo isticmaalo soo-saareyaasha Loongson, iyo sidoo kale taageerada LSX iyo LASX SIMD kordhinta ee lagu bixiyo LoongArch. Hagaajinta LoongArch gaar ah ayaa loo hirgeliyay H.264, VP8 iyo VP9 codecs.
Lagu daray taageerada nidaamka concatf, kaas oo qeexaya qaabka wareejinta liiska agabka ("ffplay concatf:split.txt"), sidoo kale waxaa lagu daray qalabeeyayaal cusub: Speex, MSN Siren, ADPCM IMA Acorn Replay, GEM (bitmaps), encoders cusub: oo lagu soo daray xoogaa yar, Apple Garaafyada (SMC), ADPCM IMA Westwood, VideoToolbox ProRes. Dejinta codeer AAC waa la bedelay si loo gaaro tayo sare.
Dhinaca kale, waxaa sidoo kale la xusay in baakadaha weelka warbaahinta lagu daray (muxer): Westwood AUD, Argonaut Games CVG, AV1 (Low Overhead Bitstream), Added Media Container Unpackers (demuxer): IMF, Argonaut Games CVG.
Waxaa lagu daray baarser cusub oo loogu talagalay codec-ga maqalka ee AMR (Laqabsiga Multi-Rate) oo lagu daray baakad xog-qaadis ah (packer) oo loogu talagalay wareejinta fiidyaha aan la ciriirin iyadoo la adeegsanayo nidaamka RTP (RFC 4175).
Sida filtarrada fiidiyooga cusub:
- qayb iyo qayb: u qaybinta durdur muqaal leh ama dhawaaq leh oo loo qaybiyo durdurro badan oo wakhti ama firam loo qaybiyo.
- hsvkey iyo hsvhold: Ku beddel qayb ka mid ah gamut-ga midabka HSV ee muuqaalka oo leh qiimayaal cawl.
- duni cawlan: iyadoo la adeegsanayo algorithm ku salaysan mala-awaalka adduunka cawlan.
- daranCodsiga hawlwadeenka Orb (nooc ka mid ah hawl wadeenka Sobel oo leh tirooyin kala duwan) fiidiyoowga gelinta.
- morpho: Waxay kuu ogolaanaysaa inaad ku dabaqdo isbeddellada qaab-dhismeedka kala duwan ee fiidiyowga.
- qarsoodi: Wuxuu cabbiraa shaandhada ugu yar iyo tan ugu sarreysa ee shaandhada hore loo dabaqay.
- xaddidid: Wuxuu qeexayaa farqiga u dhexeeya laba ama saddex durdurrada fiidiyowga.
- saxid: Wuxuu xisaabiyaa isku-xidhka-xidhiidhka u dhexeeya durdurrada fiidyaha.
- varblur: blur muuqaal doorsooma oo leh qeexida radius blur ee fiidyaha labaad.
- dherjinta lafahaCodso muuqaalka, midabaynta, ama hagaajinta muuqaalka.
- midabka midabka: Samee qulqulka fiidiyooga oo leh midab midab leh.
- libplaceboCodsiga samaynta hadhka HDR ee maktabadda libplacebo.
- vflip_vulkan, hflip_vulkan, iyo flip_vulkan: waa kala duwanaanshiyaha filtarrada fiidiyooga toosan ama toosan (vflip, hflip, iyo flip) oo la hirgeliyay iyadoo la adeegsanayo sawirada Vulkan API.
- yadif_videotoolbox: Kala duwanaanshiyaha shaandhada yadif deinterlacing ee ku salaysan qaabka VideoToolbox.
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.
