I-FFmpeg sesona sikhokelo siphambili semultimedia
I-FFmpeg 7.0 "Dijkstra" sele ikhutshwe kwaye kule nguqulo intsha Uthotho lwempucuko ebalulekileyo iyaboniswa ukusukela ekuphuculweni kokuhambelana neefomathi ezahlukeneyo, kunye nokuqaliswa kwemisebenzi emitsha, ukuphuculwa kweekhowudi, ii-decoders, ukulungiswa kwebug kunye nokunye.
Kolu guqulelo lutsha lweFFmpeg 7.0 oluvezwayo, enye yezona zinto zintsha ziphawuleka kakhulu ukuphunyezwa kwemisebenzi efanayo, oku kukuvumela ukuba wenze imisebenzi emininzi ngaxeshanye, njengokukhupha/ukupakisha izikhongozeli zemidiya, ukuguqula iikhowudi, ukufaka iikhowudi, kunye nokusebenzisa izihluzi.
Olunye uphuculo oluboniswe kwiFFmpeg 7.0 kukuhambelana neefomathi, kwaye iqaqambisa ukwaziswa kwenkxaso yokukhowudwa kwevidiyo kunye nokulungiswa kweekhowudi kwifomethi yeMPEG-5 (EVC – Essential Video Coding) ngelayibrari yangaphandle libxevd.
Ukongeza, ziye zongezwa Iinkongozelo zemidiya ezingapakishiyo kunye nabapakishi kwiifomati ezifana ne-QOA (Ngokuqinisekileyo i-Audio Kulungile) le fomati isetyenziselwa ukuhanjiswa kweaudiyo ngaphandle kokulahleka komgangatho kwaye ibalaselisa ukusebenza kwayo okuphezulu xa kuthelekiswa nezinye iifomati, kuba Kuthiwa ikhawuleza ngokuphindwe kathathu kune-Ogg-Vorbis decoding.
Inkqubo ye- Inkxaso eyongeziweyo yee-unpackers kunye nabapakishi befomathi ye-IAMF (Imodeli yomsindo ontywilayo kunye neFomathi). Le fomati yenzelwe ukusasaza isandi esijikelezileyo ngokufanelekileyo, inikezela ngesitya esibandakanya ulwazi olongezelelweyo oluyimfuneko ekusebenzeni kwe-algorithms ehlaziya izigaba zesandi kunye nokwenza imixube yesandi.
Kwelinye icala, iFFmpeg 7.0 ibandakanya idikhowuda yovavanyo yefomathi yeVVC (I-Versatile Video Coding), eyaziwa ngokuba yi-H.266. Le decoder entsha imele ukuqhubela phambili kubuchule beFFmpeg bokuphatha ucinezelo lwevidiyo yesizukulwana esilandelayo, iququzelela ukudlalwa kwakhona kunye nokuguqulwa komxholo kwizisombululo ukusuka kwi-SD ukuya kwi-8K, ngenkxaso ye-HDR (i-High Dynamic Range) kunye nevidiyo ebanzi kwi-360 degrees.
Ukongeza kolu phuculo lokuhambelana nokusebenza, kwiFFmpeg 7.0 Ukukwazi ukusebenzisa i-D3D12VA API iphunyeziwe (I-Direct 3D 12 i-Encoding yevidiyo) ye-hardware yokunyusa i-decoding yeefomathi ezahlukeneyo ezifana ne-H264, i-HEVC, i-VP9, i-AV1, i-MPEG-2 kunye ne-VC1, ukuphucula ukusebenza kunye nokusebenza kakuhle kwiinkqubo ezihambelana nale teknoloji.
Olunye utshintsho ezibalaseleyo:
- Ngoku ixhasa iikhowudi ezikhawulezileyo zehardware usebenzisa iVulkan kunye ne-libplacebo APIs.
- Inkxaso eyongeziweyo kumxholo we-URI protocol esetyenziswa kwiqonga le-Android.
- Iimfuno zokwakha zandile; Umqambi oxhasa umgangatho we-C11 ngoku uyafuneka ukuqokelela iFFmpeg.
- Kwi-QSV (Ividiyo ye-Intel Quick Sync) esekwe kwi-encoders, indlela yolawulo lwe-bit engagqibekanga itshintshiwe ukusuka kwi-VBR ukuya kwi-CQP.
- I-unpacker entsha ye-DVD-Video media containers iye yaziswa, ngokusekelwe kwi-libdvdnav kunye ne-libdvdread libraries ezivela kwiprojekthi ye-VideoLAN.
- Ngoku kunokwenzeka ukuhambisa imethadatha kwiipakethi kuphunyezo lwefomathi ye-flv.
- Kongezwe i-DXV DXT1 encoder kunye ne-LEAD MCMP decoder.
- Kwiifomethi zeMP4 kunye ne-ISOBMFF, ukubandakanywa kwe-AVE metadata kuphunyeziwe.
- Inkxaso yetekhnoloji ye-AFGS1, esetyenziswe kwinkcazo ye-AV1 yeFilimu yeGrain, yongezwe ukuphucula ukunyanzeliswa kwemifanekiso yengqolowa.
- Inkxaso eyongeziweyo yemifanekiso emileyo kwiifomathi ze-HEIF kunye ne-AVIF, kunye nemifanekiso emile.
- Iprofayile yeDolby Vision ngoku iyafumaneka kwifomati ye-AV1.
- Ekugqibeleni, inkxaso inikezelwa ekugqithiseni imethadatha ye-HDR10 xa kufakwa iikhowudi nge-libx264, libx265, kunye ne-libsvtav1 iilayibrari.
Kwabo banomdla wokufunda ngakumbi malunga noku kukhutshwa okutsha okanye ukufunda ngakumbi ngeFFmpeg, unokujonga iinkcukacha Kule khonkco ilandelayo.
Khuphela kwaye ufumane iFFmpeg 7.0
