Kuburitswa kweFFmpeg 6.0 multimedia package

Mushure memwedzi mitanhatu yebudiriro, iyo FFmpeg 6.0 multimedia package inowanikwa, iyo inosanganisira seti yezvikumbiro uye muunganidzwa wemaraibhurari ekushanda pane akasiyana mafomati emultimedia (kurekodha, kushandura uye kudhirodha maodhiyo nemavhidhiyo mafomati). Iyo package inogoverwa pasi pe LGPL uye GPL marezinesi, FFmpeg budiriro inoitwa padhuze neMPlayer chirongwa.

Pakati pekuchinja kwakawedzerwa kuFFmpeg 6.0 ndeiyi:

  • Kuvaka ffmpeg mune yakawanda-yakarukwa modhi yakaitwa inosungirwa. Imwe neimwe midhiya mudziyo wrapper (muxer) ikozvino inomhanya mune imwe tambo.
  • Tsigiro yeVAAPI neQSV (Quick Sync Vhidhiyo) inoisirwa kukodha uye kudhikodha VP9 uye HEVC ine 4:2:2 uye 4:4:4 color subsampling, 10- uye 12-bit kudzika kwemavara encoding.
  • Yakawedzerwa rutsigiro rweiyo oneVPL (imwe API Vhidhiyo Processing Raibhurari) kushandisa Intel QSV (Kurumidza Sync Vhidhiyo) hardware yekumhanyisa tekinoroji.
  • Yakawedzera AV1 encoder ine hardware kukwidziridzwa kwakavakirwa paQSV.
  • Sarudzo dzakawedzerwa kune iyo ffmpeg utility:
    • "-shortest_buf_duration" kuseta hurefu hwenguva yemafuremu akavharwa (kurebesa, kunowedzera kurongeka mu "-pfupi" modhi, asi yakakwirira yekuyeuka uye latency).
    • β€œ-stats_enc_pre[_fmt]”, β€œ-stats_enc_post[_fmt]” uye β€œ-stats_mux_pre[_fmt]” yekurekodha furemu-ne-frame ruzivo pamusoro pehova dzakasarudzwa pamatanho akasiyana encoding mufaira rataurwa.
    • "-fix_sub_duration_heartbeat" kutsanangura kutepfenyura kwevhidhiyo kurova kwemoyo kunoshandiswa kupatsanura zvinyorwa zvidiki.
  • Iyo sefagirafu syntax yakawedzerwa kuti ibvumidze sarudzo kukosha kupfuudzwa kubva kune yakatarwa faira. Iro zita refaira rinotsanangurwa nekutsanangura kukosha kwakatarwa ne '/', semuenzaniso, "ffmpeg -vf drawtext=/text=/tmp/some_text" inotakura parameter yemavara kubva pa /tmp/some_text file.
  • Yakawedzerwa rutsigiro rwemafomati emifananidzo: WBMP (Wireless Application Protocol Bitmap), Radiance HDR (RGBE).
  • Yakawedzera madhikodha matsva: APAC, bonk, Micronas SC-4, Media 100i, ViewQuest VQC, MediaCodec (NDKMediaCodec), WADY DPCM, CBD2 DPCM, XMD ADPCM, WavArc, RKA.
  • Yakawedzera encoder matsva: nvenc AV1, MediaCodec.
  • Yakawedzera midhiya mudziyo unpackers (demuxer): SDNS, APAC, bonk, LAF, WADY DPCM, XMD ADPCM, WavArc, RKA.
  • CrystalHD madhikodha akaregwa.
  • Masefa evhidhiyo matsva:
    • ddagrab - Bata Windows desktop vhidhiyo kuburikidza neDesktop Duplication API.
    • corr - Inosarudza kuwirirana pakati pemavhidhiyo maviri.
    • ssim360 - kufanana kuongororwa kwemavhidhiyo akabatwa mu 360 Β° modhi.
    • hstack_vaapi, vstack_vaapi uye xstack_vaapi - kusanganisa mavhidhiyo akati wandei (vhidhiyo yega yega inoratidzwa munzvimbo yayo yechidzitiro) uchishandisa VAAPI yekumhanyisa.
    • backgroundkey - inoshandura static kumashure kuita pachena.
    • Iyo modhi yekuona nzvimbo yechirimwa inoenderana nemavekita uye mitsetse yekufamba yakawedzerwa kune chirimwa sefa.
  • Masefa matsva eruzha:
    • showcwt -odhiyo kune vhidhiyo shanduko ine spectrum frequency kuona uchishandisa inoenderera wavelet shanduko uye morlet.
    • adrc - Isa sefa kune yekuisa odhiyo rwizi kuti uchinje iyo spectral dynamic renji.
    • a3dscope - Inoshandura odhiyo yekuisa kuita spatial 3D odhiyo.
    • afdelaysrc - Inogadzira finite impulse response (FIR) coefficients.
  • New bitstream filters:
    • Shandura kubva media100 kuenda mjpegb.
    • Shandura kubva kuDTS kuenda kuPTS.
