Mushure memwedzi gumi yebudiriro kuburitswa kweiyo vhezheni itsva yeFFmpeg 5.0 yakaziviswa, iyo inosanganisira seti yezvishandiso uye muunganidzwa wemaraibhurari ekushanda pane akasiyana mafomati emultimedia (kurekodha, kushandura uye kudhirodha maodhiyo nemavhidhiyo mafomati).
Shanduko yakakosha munhamba yeshanduro imhaka yekukosha kweAPI shanduko uye shanduko kune itsva yekuburitsa chizvarwa chirongwa, maererano nezvinobudiswa zvitsva zvitsva zvichaumbwa kamwe chete pagore, uye zvinobudiswa nenguva yakawedzerwa yekutsigira - kamwe chete pamakore maviri. FFmpeg 5.0 ichave yekutanga LTS vhezheni yeprojekiti.
Main nyowani maficha eFFmpeg 5.0
Mune iyi vhezheni itsva kwakakosha kucheneswa kwekare APIs encoding uye decoding, pamwe nekushandura kune itsva N: M API, iyo inopa imwechete programming interface yeaudio uye vhidhiyo, pamwe neakaparadzana macodecs ekupinza uye kubuda hova.
Tambien Zvinotaurwa kuti ese akare akanyorwa APIs akabviswa yakaderedzwa uye yakawedzera API nyowani ye bitstream mafirita.
Kunze kwaizvozvo, akawedzera akasiyana mafomati uye macodecs: Media mudziyo unpackers haichabatanidza iyo yakazara decoder mamiriro. Yakabviswa APIs yekunyoresa macodecs uye mafomati: ese mafomati agara akanyoreswa.
Yakawedzerwa rutsigiro rweLoongArch architecture inoshandiswa mumaLoongson processors, pamwe nerutsigiro rweLSX neLASX SIMD yekuwedzera yakapihwa muLoongArch. Yakanyanya LoongArch optimizations yakashandiswa yeH.264, VP8 uye VP9 macodecs.
Yakawedzerwa rutsigiro rweconcatf protocol, iyo inotsanangura mafomati ekufambisa runyoro rwezviwanikwa ("ffplay concatf:split.txt"), yakawedzerawo madhikodha matsva: Speex, MSN Siren, ADPCM IMA Acorn Replay, GEM (bitmaps), encoder mitsva: yakarongedzwa mumabits, Apple. Graphics (SMC), ADPCM IMA Westwood, VideoToolbox ProRes. Iyo AAC encoder marongero akachinjwa kuti awane yepamusoro mhando.
Ukuwo, zvinocherechedzwawo kuti media container packers yakawedzerwa (muxer): Westwood AUD, Argonaut Games CVG, AV1 (Low Overhead Bitstream), Yakawedzerwa Media Container Unpackers (demuxer): IMF, Argonaut Games CVG.
Yakawedzera parser nyowani ye AMR (Adaptive Multi-Rate) audio codec uye yakawedzera payload data packer (packer) yekufambisa vhidhiyo isina kudzvanywa uchishandisa iyo RTP protocol (RFC 4175).
Kana ari mafirita matsva evhidhiyo:
- chikamu uye chikamu: kupatsanura rukova nevhidhiyo kana ruzha kuita nzizi dzakawanda dzakakamurwa nenguva kana mafuremu.
- hsvkey uye hsvhold: Tsiva chikamu cheHSV color gamut muvhidhiyo ine grayscale kukosha.
- grayworld: kushandisa algorithm yakavakirwa pane grey world hypothesis.
- scharr: kushandiswa kweOrb opareta (musiyano weSobel opareta ine akasiyana coefficients) kune yekupinda vhidhiyo.
- morpho: Inokutendera kuti ushandise akasiyana morphological shanduko kuvhidhiyo.
- Latency: Inoyera iyo shoma uye yakanyanya kusefa kunonoka kune yakamboshandiswa sefa.
- limitdiff: Inotsanangura musiyano uripo pakati pemafashama maviri kana matatu evhidhiyo.
- xcorrelate: Inoverengera muchinjika-kuwirirana pakati pevhidhiyo hova.
- varblur: shanduko yevhidhiyo blur ine blur radius tsananguro yevhidhiyo yechipiri.
- bone saturation: Isa hue, saturation, kana kujeka kugadziridzwa kuvhidhiyo.
- color spectrum: Gadzira vhidhiyo inoyerera ine yakapihwa ruvara spectrum.
- libplacebo: Chikumbiro chekupa HDR shaders kubva ku libplacebo raibhurari.
- vflip_vulkan, hflip_vulkan, uye flip_vulkan: misiyano yeyakatwasuka kana yakachinjika vhidhiyo inopeperesa mafirita (vflip, hflip, uye flip) inoshandiswa uchishandisa Vulkan graphics API.
- yadif_videotoolbox: Musiyano weyadif deinterlacing sefa zvichibva paVideoToolbox framework.
Finalmente kune avo vanofarira kuziva zvakawanda nezvazvo nezve kuburitswa kutsva uku, unogona kutarisa izere changelog mune iyi link.
Nguva kune avo vanoda kuisa kana kugadzirisa kubva kuFFmpeg iwe unofanirwa kuziva kuti pasuru iyi inowanikwa munzvimbo zhinji dzeLinux kana kana uchida iwe unogona kurodha pasi rekodhi kodhi kubva pane iyi link iripazasi.
