Ukukhishwa kwephakheji ye-multimedia ye-FFmpeg 4.3 ngokusekelwa kwe-Vulkan graphics API

Ngemva kwezinyanga eziyishumi zentuthuko iyatholakala iphakheji ye-multimedia FFmpeg 4.3, okufaka isethi yezinhlelo zokusebenza kanye neqoqo lemitapo yolwazi yokusebenza kumafomethi ahlukahlukene we-multimedia (ukurekhoda, ukuguqula nokuqopha amafomethi omsindo nevidiyo). Iphakheji isatshalaliswa ngaphansi kwamalayisensi e-LGPL kanye ne-GPL, ukuthuthukiswa kwe-FFmpeg kwenziwa eduze kwephrojekthi I-MPlayer.

Из izinguquko, kwengezwe ku-FFmpeg 4.3, singagqamisa:

• Iphakheji ihlanganisa umhlaseli wezithombe ngefomethi ye-WebP;
• Kusetshenziswe amadekhoda e-MJPEG kanye ne-VP9 kusetshenziswa indlela yokusheshisa ihadiwe I-Intel QSV (Ividiyo Yokuvumelanisa Ngokushesha), kanye nesishumeki se-VP9 esisekelwe ku-Intel QSV;
• Ukusekelwa okunwetshiwe kwezitayela zemibhalo engezansi ngefomethi ye-3GPP Yemibhalo Engezansi Yombhalo Onesikhathi;
• Kwengezwe i-encoder wrapper nge-API I-Microsoft Media Foundation;
• Kwengezwe isifaki khodi se-ADCMM sedatha yomsindo esetshenziswa kumidlalo ye-Simon & Schuster Interactive;
• Kwengezwe amadekhoda amasha: 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 DPCM kanye ne-CRI HCA;
• Kwengezwe i-streamhash media container packer (muxer) futhi kwasetshenziswa ikhono lokupakisha i-pcm nama-pgs ezitsheni ze-m2ts;
• Izinqamuli zesiqukathi semidiya esingeziwe (i-demuxer): I-AV1 enezandiso ezivela kuhlelo lokusebenza B,
  Argonaut Games ASF, Real War KVAG, Rayman 2 APM, LEGO Racers ALP (.tun kanye .pcm), FWSE, DERF, CRI HCA, Pro Pinball Series Soundbank;

• Kusha izihlungi:
  • v360 - Iguqula ividiyo ye-360-degree ibe amafomethi ahlukahlukene;
  • pheqa — iskrola ividiyo ivundlile noma ibheke phezulu ngesivinini esinikeziwe;
  • i-photosensitivity — isusa ukukhanya okukhanyayo kanye nezinguquko ezingazelelwe ekugqameni kuvidiyo, okungase kubangele isithuthwane;
  • arnn - Isihlungi sokucindezela umsindo wenkulumo sisebenzisa inethiwekhi ye-neural ephindaphindiwe;
  • zamazwe amabili - yenza i-anti-aliasing yendawo ngenkathi igcina imiphetho;
  • maskedmin и imaskimax - hlanganisa ukusakazwa kwevidiyo okubili ngokusekelwe kumehluko nokusakaza kwesithathu;
  • ophakathi — isihlungi sokunciphisa umsindo esikhetha i-pixel ye-median kunxande elingana phakathi kwendawo ebekiwe;
  • Ukuhlanganisa uzimele we-AV1 - ukuhlanganisa ozimele ekusakazweni kwe-AV1;
  • axcorrelate - ibala ukuhlobana okujwayelekile phakathi kwemisakazo emibili yomsindo;
  • letogram — ibala futhi ibonise i-histogram yokusabalalisa imibala kuvidiyo;
  • ozimele — ishintsha isethi yamafreyimu kuvidiyo ngamafreyimu athile asuka kokunye ukusakaza;
  • xfade и xfade_opencl -
    ukufiphala ngokushintsha kusuka ekusakazweni kwevidiyo kuya kokunye;

  • afirsrc - ikhiqiza ama-coefficient e-FIR kusetshenziswa indlela yesampula yemvamisa;
  • pad_opencl - ingeza i-padding esithombeni;
  • CAS — isebenzisa isihlungi sokulola i-CAS (Contrast Adaptive Sharpen) kuvidiyo;
  • ama-anlms - isebenzisa i-algorithm evamile I-LMS (Okungenani izikwele) kuya ekusakazeni komsindo kokuqala, kubalwa ama-coefficients ngokusekelwe kumehluko ngokusakaza kwesibili;
  • overlay_cuda - ubeka isiqeshana sevidiyo eyodwa phezu kwenye;
  • i-tmedian — isihlungi sokunciphisa umsindo esisebenzisa amaphikseli amaphakathi avela kumafreyimu amaningana aphumelelayo;
  • i-maskthreshold — ikhetha amaphikseli lapho ihlunga ngokusekelwe ekuqhathaniseni umehluko phakathi kokusakazwa kwevidiyo okubili ngevelu yomkhawulo;
  • i-asubboost - ithuthukisa amaza e-subbuffer;
  • pcm_rechunk — ipakisha kabusha umsindo we-PCM ngokucabangela imvamisa yesampula eshiwo noma izinga lokudlulisa iphakethe;
  • scdet — inquma izinguquko endaweni yesehlakalo kuvidiyo (isibonelo, ukunquma ukunyakaza kuhlaka);
  • ama-gradients - ikhiqiza ukusakazwa kwevidiyo ngama-gradients;
  • sierpinski - ikhiqiza ukusakazwa kwevidiyo ngama-fractals I-Sierpinski;
  • kuze kube — uhlahlela ividiyo eyenziwe ngezicucu ibe yizithombe ezihlukene;
  • dblur - isebenzisa ukufiphala kokuqondisa.
