Tom qab kaum lub hlis ntawm txoj kev loj hlob, FFmpeg 6.1 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 6.1 yog:
- Muaj peev xwm siv Vulkan API rau kho vajtse acceleration ntawm video decoding nyob rau hauv H264, HEVC thiab AV1 hom tau siv.
- Ntxiv AV1 video hom encoder raws li VAAPI.
- Ntxiv kev txhawb nqa rau kev siv HEVC, VP9 thiab AV1 codecs hauv cov kwj raws raws tu qauv rtmp thiab hauv cov ntaub ntawv hauv flv hom.
- Ntxiv parser, encoder thiab decoder rau cov khoom ntim hauv EVC (Qhov tseem ceeb Video Coding), tsim los ntawm MPEG pawg ua haujlwm raws li MPEG-5 tus qauv.
- Kev txhawb nqa ntxiv rau VAAPI ntawm Windows systems nrog lub tsev qiv ntawv libva-win32.
- Ua kom muaj peev xwm siv P_SKIP tsis ua kom nrawm video encoding siv lub tsev qiv ntawv libx264.
- Ntxiv encoder rau video hauv Microsoft RLE hom.
- Ntxiv cov decoders tshiab Playdate, RivaTuner, vMix thiab OSQ.
- Lub ARIB STD-B24 subtitle decoder yog siv raws li lub tsev qiv ntawv libaribcaption.
- Ntxiv cov thawv ntim khoom tawm (demuxer): Raw VVC (Versatile Video Coding, tus qauv tshiab H.266/MPEG-I Part 3), Playdate, Raw AC-4, OSQ, CRI USM.
- Ntxiv cov thawv ntim khoom (muxer): Raw AC-4 thiab Raw VVC.
- Tshiab cov ntxaij lim dej video:
- color_vulkan - tsim ib lub thav duab ntawm cov xim muab los ntawm kev hu rau Vulkan API.
- bwdif_vulkan - ua deinterlacing siv BWDIF (Bob Weaver Deinterlacing Filter) algorithm siv Vulkan API.
- bwdif_cuda - deinterlacing siv BWDIF algorithm, siv raws li CUDA API.
- nlmeans_vulkan - tshem tawm suab nrov siv cov Tsis yog-lub zos txhais tau tias algorithm siv Vulkan API.
- xfade_vulkan - Kev siv cov nyhuv ploj siv Vulkan API.
- zoneplate - tsim cov lus sim video raws li Fresnel cheeb tsam phaj.
- scale_vt thiab transpose_vt yog nplai thiab hloov cov lim dej siv siv VideoToolBox API (macOS).
- Kev them nyiaj yug hais kom ua tau ntxiv rau cov setpts thiab asetpts lim.
- Tshiab suab filters:
- arls - siv cov xwm txheej tsawg kawg nkaus kom kwv yees qhov tsis sib xws ntawm ib lub suab mus rau lwm qhov.
- afireqsrc - Tsim ib qho FIR equalizer (finite impulse teb lim).
- apsnr - ntsuas lub teeb liab-rau-nruab theem.
- asisdr - ntsuas lub teeb liab-distortion theem.
- Tshiab bitstream filters:
- Kho cov metadata hauv VVC (Versatile Video Coding, H.266) ntws.
- Hloov VVC ntws los ntawm MP4 rau "Annex B".
- Ntxiv qhov "-readrate_initial_burst" kev xaiv rau ffmpeg qhov hluav taws xob los teeb tsa lub sijhawm nyeem thawj zaug, tom qab ntawd qhov kev txwv "-readrate" pib siv. Qhov kev xaiv '-sab saum toj' tau deprecated thiab cov lim setfield yuav tsum tau siv hloov.
- Cov khoom siv hluav taws xob ffprobe tau ntxiv qhov "-output_format" kev xaiv, uas zoo ib yam li "-of" kev xaiv thiab tuaj yeem siv los txiav txim siab cov ntawv tso zis (piv txwv li, koj tuaj yeem siv json hom). XML tso zis schema tau hloov kho los txhawb ntau lub ntsiab lus khi rau ib tus niam txiv ib leeg.
