Lix bilood ka dib horumarinta, xirmada FFmpeg 6.0 multimedia waa la heli karaa, 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). Xirmada waxaa lagu qaybiyaa shatiga LGPL iyo GPL, horumarinta FFmpeg waxaa lagu fuliyaa dhinaca mashruuca MPlayer.
Qaar ka mid ah isbeddelada lagu daray FFmpeg 6.0 waxaa ka mid ah:
- Dhisida ffmpeg ee qaabka dunta badan leh ayaa laga dhigay qasab. Ku duub weel kasta oo warbaahin ah (muxer) hadda wuxuu ku socdaa dun gaar ah.
- Taageerada la hirgaliyay ee VAAPI iyo QSV (Video sync degdeg ah) ee codaynta iyo dejinta VP9 iyo HEVC oo leh 4:2:2 iyo 4:4:4 midab hoosaadka, 10- iyo 12-bit codeing qoto dheer ee midabka.
- Taageero lagu daray maktabadda oneVPL (oneAPI Video Processing Library) si loo isticmaalo Intel QSV (Fiidiyowga Degdega ah ee Fiidiyowga) farsamada dardargelinta qalabka.
- AV1 codeeyaha lagu daray oo leh dardargelinta qalabka ku salaysan QSV.
- Ikhtiyaarada ayaa lagu daray utility ffmpeg:
- "-shortest_buf_duration" si loo dejiyo muddada ugu badan ee fiimyada go'an (inta dheer, waa ay saraysaa saxnaanta habka "-gaaban", laakiin isticmaalka xusuusta sare iyo daahitaanka).
- "-stats_enc_pre[_fmt]", "-stats_enc_post[_fmt]" iyo "-stats_mux_pre[_fmt]" ee loogu talagalay duubista macluumaadka qaab-qaabaysan ee ku saabsan durdurrada la doortay ee heerarka kala duwan ee codaynta faylka la cayimay.
- "-fix_sub_duration_heartbeat" si loo qeexo qulqulka fiidyaha garaaca wadnaha ee loo isticmaalo in lagu kala qaybiyo qoraal-hoosaadyo.
- Isku xirka filtarrada waa la kordhiyey si loogu ogolaado qiyamka ikhtiyaariga ah in laga gudbiyo fayl cayiman. Magaca faylka waxaa lagu qeexay iyadoo la qeexayo qiimaha lagu sii hormariyay '/', tusaale ahaan, "ffmpeg -vf drawtext=/text=/tmp/some_text" waxay ka soo rari doontaa cabbirka qoraalka faylka /tmp/some_text.
- Taageerada lagu daray ee qaababka sawirka: WBMP (Wireless Application Protocol Bitmap), Radiance HDR (RGBE).
- Dekodeerayaal cusub oo lagu daray: APAC, bonk, Micronas SC-4, Media 100i, ViewQuest VQC, MediaCodec (NDKMediaCodec), WADY DPCM, CBD2 DPCM, XMD ADPCM, WavArc, RKA.
- Waxaa lagu daray cod-bixiyeyaal cusub: nvenc AV1, MediaCodec.
- Baakadaha weelka warbaahinta lagu daray (demuxer): SDNS, APAC, bonk, LAF, WADY DPCM, XMD ADPCM, WavArc, RKA.
- CrystalHD decoders waa la jaray
- filtarrada fiidiyooga cusub:
- ddagrab - Ku qabso fiidiyowyada desktop-ka ee Windows adoo isticmaalaya Desktop Duplication API.
- corr - Waxay go'aamisaa xidhiidhka ka dhexeeya laba fiidiyow.
- ssim360 - qiimaynta isku midka ah ee fiidiyowyada lagu qabtay qaabka 360Β°.
- hstack_vaapi, vstack_vaapi iyo xstack_vaapi - isku darka dhawr fiidyow (fidyow kastaa waxa lagu muujiyay aaggeeda shaashadda) iyadoo la isticmaalayo VAAPI dardargelinta.
- backgroundkey - waxay u rogtaa asalka taagan mid hufan.
- Habka lagu go'aaminayo aagga dalagga ee ku salaysan vectors iyo cidhifyada dhaqdhaqaaqa ayaa lagu daray filter-ka-warshadaynta.
- filtarrada codka cusub:
- showcwt - maqal iyo muuqaal beddelaad leh oo leh muuqaal soo noqnoqda spectrum iyadoo la adeegsanayo beddelka mawjadaha iyo mowjadaha joogtada ah.
- adrc - Ku cod shaandhaynta qulqulka maqalka gelinta si aad u bedesho kala duwanaanta firfircoonida.
- a3dscope - Wuxuu u beddelaa cod gelinta cod 3D meel bannaan.
- afdelaysrc - Waxay abuurtaa jawaab celin xaddidan (FIR) isku-xireyaasha.
- filtarrada cusub ee bitstream:
- Ka beddel media100 una beddel mjpgb.
- U beddelo DTS una beddelo PTS.
