Tom qab kaum lub hlis ntawm txoj kev loj hlob, FFmpeg 4.4 multimedia pob muaj, uas suav nrog cov txheej txheem ntawm kev siv thiab sau cov tsev qiv ntawv rau kev ua haujlwm ntawm ntau hom ntawv xov xwm (sau, hloov pauv thiab txiav suab thiab video tawm tswv yim). Cov pob tau muab faib raws li LGPL thiab GPL cov ntawv tso cai, FFmpeg kev txhim kho yog ua tiav nyob ib sab ntawm MPlayer project.
Ntawm cov kev hloov pauv ntxiv rau FFmpeg 4.4 yog:
- Muaj peev xwm siv VDPAU (Video Decode thiab nthuav qhia) API rau kho vajtse acceleration ntawm video decoding nyob rau hauv HEVC/H.265 (10/12bit) thiab VP9 (10/12bit) tawm tswv yim.
- Kev them nyiaj yug yog muab rau kev txiav txim video hauv AV1 hom siv NVIDIA NVDEC thiab Intel QSV (Quick Sync Video) kho vajtse acceleration xyaw, nrog rau siv DXVA2/D3D11VA API.
- Ntxiv lub peev xwm los encode AV1 hauv monochrome siv lub tsev qiv ntawv libaom (yuav tsum muaj tsawg kawg yog version 2.0.1).
- Lub peev xwm los encode video hauv AV1 hom ntawv tau siv los siv SVT-AV1 (Scalable Video Technology AV1) encoder, uas siv cov khoom siv sib txuas ua ke muaj peev xwm pom hauv Intel CPUs niaj hnub.
- Ntxiv tso zis ntaus ntawv ntawm AudioToolbox moj khaum.
- Ntxiv kev txhawb nqa rau gophers raws tu qauv (gopher dhau TLS).
- Ntxiv kev txhawb nqa rau RIST (Reliable Internet Stream Transport) raws tu qauv siv librist.
- Tshem tawm kev txhawb nqa rau libwavpack raws li encoder.
- Ntxiv cov decoders tshiab: AV1 (nrog cov khoom siv nrawm nrawm), AV1 (ntawm VAAPI), AVS3 (ntawm libuavs3d), Cintel RAW, PhotoCD, PGX, IPU, MobiClip Video, MobiClip FastAudio, ADPCM IMA MOFLEX, Argonaut Games Video, MSP v2 ( Microsoft Paint), Simbiosis IMX, Digital Pictures SGA.
- Ntxiv cov encoders tshiab: RPZA, PFM, Cineform HD, OpenEXR, SpeedHQ, ADPCM IMA Ubisoft APM, ADPCM Argonaut Games, High Voltage Software ADPCM, ADPCM IMA AMV, TTML (subtitles).
- Ntxiv cov thawv ntim khoom (muxer): AMV, Rayman 2 APM, ASF (Argonaut Games), TTML (subtitles), LEGO Racers ALP (.tun thiab .pcm).
- Ntxiv cov thawv ntim khoom tawm (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).
- Cov parsers tshiab tau ntxiv: IPU, Dolby E, CRI, XBM.
- Cov lim dej tshiab:
- chromanr - txo cov suab nrov hauv video.
- afreqshift thiab aphaseshift - hloov lub zaus thiab theem ntawm lub suab.
- adenorm - ntxiv suab nrov ntawm ib theem.
- speechnorm - ua kev hais lus normalization.
- asupercut - txiav ntau zaus tshaj 20 kHz los ntawm lub suab.
- asubcut - txiav tawm subbuffer zaus.
- asuperpass thiab asuperstop - kev siv ntawm Butterworth zaus lim.
- shufflepixels - rearranges pixels hauv video thav duab.
- tmidequalizer - daim ntawv thov ntawm Temporal Midway Video Equalization nyhuv.
- estdif - deinterlacing siv Edge Slope Tracing algorithm.
- epx yog lub lim loj rau tsim pixel kos duab.
- shear - shear video transformation.
- kirsch - Siv Kirsch tus neeg teb xov tooj rau video.
- colortemperature β kho cov xim kub ntawm cov yees duab.
- colorcontrast - kho qhov sib txawv xim ntawm RGB Cheebtsam rau video.
- colorcorrect - dawb tshuav nyiaj li cas hloov rau video.
- colorize - xim overlay ntawm video.
- exposure - kho cov qib raug rau video.
- monochrome - hloov xim video rau greyscale.
- aexciter - tiam ntawm cov khoom siv suab nrov uas tsis muaj nyob hauv thawj lub teeb liab.
- vif thiab msad - kev txiav txim siab ntawm VIF (Visual Information Fidelity) thiab MSAD (Mean Sum of Absolute Differences) coefficients los ntsuas qhov sib txawv ntawm ob lub yeeb yaj kiab.
- tus kheej - txiav txim siab qhov sib txawv ntawm ob lub yeeb yaj kiab.
- setts β teev PTS (lub sij hawm nthuav qhia lub sij hawm) thiab DTS (txiav txim siab lub sij hawm stamp) nyob rau hauv pob ntawv (bitstream).
