Mushure memwedzi gumi yebudiriro, iyo FFmpeg 4.4 multimedia package inowanikwa, iyo inosanganisira seti yezvikumbiro uye muunganidzwa wemaraibhurari ekushanda pane akasiyana mafomati emultimedia (kurekodha, kushandura uye decoding odhiyo nemavhidhiyo mafomati). Iyo package inogoverwa pasi pe LGPL uye GPL marezinesi, FFmpeg budiriro inoitwa padhuze neMPlayer chirongwa.
Pakati pekuchinja kwakawedzerwa kuFFmpeg 4.4 ndeiyi:
- Kugona kushandisa VDPAU (Vhidhiyo Decode uye Presentation) API yehardware acceleration yevhidhiyo decoding muHEVC/H.265 (10/12bit) uye VP9 (10/12bit) mafomati akashandiswa.
- Tsigiro inopihwa yevhidhiyo decoding muAV1 fomati uchishandisa NVIDIA NVDEC uye Intel QSV (Quick Sync Vhidhiyo) hardware yekumhanyisa injini, pamwe nekushandisa iyo DXVA2/D3D11VA API.
- Yakawedzera kugona encode AV1 mune monochrome uchishandisa libaom raibhurari (inoda kanenge vhezheni 2.0.1).
- Iko kugona kuvharidzira vhidhiyo muAV1 fomati yakashandiswa uchishandisa SVT-AV1 (Scalable Vhidhiyo Technology AV1) encoder, inoshandisa iyo hardware parallel computing hunyanzvi inowanikwa muIntel CPU yemazuva ano.
- Yakawedzera kuburitsa mudziyo kuburikidza neAudioToolbox chimiro.
- Yakawedzerwa rutsigiro rwegophers protocol (gopher pamusoro peTLS).
- Yakawedzera rutsigiro rweRIST (Yakavimbika Internet Stream Transport) protocol uchishandisa librist.
- Yakabviswa rutsigiro rwe libwavpack yakavakirwa encoder.
- Yakawedzera madhikodha matsva: AV1 (ine Hardware yakakwidziridzwa decoding), AV1 (kuburikidza neVAAPI), AVS3 (via libuavs3d), Cintel RAW, PhotoCD, PGX, IPU, MobiClip Vhidhiyo, MobiClip FastAudio, ADPCM IMA MOFLEX, Argonaut Mitambo Vhidhiyo, MSP v2 ( Microsoft Paint), Simbiosis IMX, Digital Mifananidzo SGA.
- Yakawedzera encoders mitsva: RPZA, PFM, Cineform HD, OpenEXR, SpeedHQ, ADPCM IMA Ubisoft APM, ADPCM Argonaut Games, High Voltage Software ADPCM, ADPCM IMA AMV, TTML (subtitles).
- Yakawedzerwa midhiya yemudziyo packers (muxer): AMV, Rayman 2 APM, ASF (Argonaut Games), TTML (subtitles), LEGO Racers ALP (.tun uye .pcm).
- Yakawedzera midhiya mudziyo unpackers (demuxer): AV1 (Low overhead bitstream), ACE, AVS3, MacCaption, MOFLEX, MODS, MCA, SVS, BRP (Argonaut Games), DAT, aax, IPU, xbm_pipe, binka, Simbiosis IMX, Digital Pictures SGA , MSP v2 (Microsoft Paint).
- Zvitsva zvitsva zvakawedzerwa: IPU, Dolby E, CRI, XBM.
- Masefa matsva:
- chromanr - inoderedza ruzha rwemavara muvhidhiyo.
- afreqshift uye aphaseshift - shandura frequency uye chikamu chekunzwika.
- adenorm - inowedzera ruzha pane imwe nhanho.
- Speechnorm - inoita kutaura kwakajairika.
- asupercut - inocheka frequency pamusoro pe20 kHz kubva pakurira.
- asubcut - inocheka subbuffer frequency.
- asuperpass uye asuperstop - kushandiswa kweButterworth frequency mafirita.
- shufflepixels - inorongazve mapixels mumavhidhiyo mafuremu.
- tmidequalizer - kushandiswa kweiyo Temporal Midway Vhidhiyo Equalization maitiro.
- estdif - deinterlacing uchishandisa Edge Slope Tracing algorithm.
- epx ndeye yekuwedzera sefa yekugadzira pixel art.
- shear - shear vhidhiyo shanduko.
- kirsch - Nyorera Kirsch opareta kuvhidhiyo.
- colortemperature - gadzirisa kupisa kwemavara kwevhidhiyo.
- colorcontrast - inogadzirisa musiyano wemavara pakati pezvikamu zveRGB zvevhidhiyo.
- colorcorrect - chena chiyero kugadziridzwa kwevhidhiyo.
- colorize - kuvharika kwemavara pavhidhiyo.
- exposure - inogadzirisa chiyero chekuratidzwa kwevhidhiyo.
- monochrome - inoshandura vhidhiyo yemavara kuita greyscale.
- aexciter - chizvarwa chepamusoro-frequency inonzwika zvikamu zvisipo muchiratidzo chekutanga.
- vif uye msad - kutsunga kweVIF (Visual Information Fidelity) uye MSAD (Mean Sum of Absolute Differences) coefficients kuongorora mutsauko uripo pakati pemavhidhiyo maviri.
- identity - kuona mwero wemutsauko pakati pemavhidhiyo maviri.
- seti - inoseta PTS (chitambi chenguva yemharidzo) uye DTS (decoding nguva chitambi) mumapaketi (bitstream).
