Tso tawm ntawm SVT-AV1 0.6 video encoder tsim los ntawm Intel

Intel luam tawm tsev qiv ntawv tso tawm SVT-AV1 0.6 (Scalable Video Technology AV1), uas muab lwm txoj kev encoder thiab decoder rau AV1 video encoding hom, uas siv cov khoom siv sib xyaw ua ke muaj peev xwm pom hauv Intel CPUs niaj hnub. Lub hom phiaj tseem ceeb ntawm SVT-AV1 yog kom ua tiav ib theem ntawm kev ua tau zoo tsim nyog rau kev hloov pauv hauv video thiab siv hauv video-on-demand (VOD) cov kev pabcuam. Cov cai tau tsim los ua ib feem ntawm OpenVisualCloud project, uas kuj tsim cov encoders SVT-HEVC и SVT-VP 9thiab faib los ntawm raws li BSD daim ntawv tso cai.

Txhawm rau siv SVT-AV1, koj xav tau yam tsawg kawg yog tsib tiam Intel Core processors (Intel Xeon E5-v4 thiab tshiab dua CPUs). Encoding 10-ntsis AV1 ntws ntawm 4K zoo yuav tsum muaj 48 GB ntawm RAM, 1080p - 16 GB, 720p - 8 GB, 480p - 4 GB. Vim qhov nyuaj ntawm cov algorithms siv hauv AV1, encoding hom ntawv no yuav tsum muaj peev txheej ntau dua li lwm hom ntawv, uas tsis tso cai rau kev siv tus qauv AV1 encoder rau lub sijhawm hloov pauv. Piv txwv li, tus qauv encoder los ntawm AV1 qhov project
nws yuav tsum tau 5721, 5869 thiab 658 lub sijhawm suav ntau dua piv rau x264 (profile "main"), x264 (profile "high") thiab libvpx-vp9 encoders.

Cov kev hloov pauv hauv qhov kev tso tawm tshiab ntawm SVT-AV1 suav nrog qhov sib ntxiv ntawm kev siv lub tshuab txiav tawm thawj zaug (yav dhau los tsuas yog encoding tau txais kev txhawb nqa) thiab kev txhawb nqa rau kev sib txuas hauv tsev qiv ntawv zoo li qub. Tshiab SIMD optimizations kuj tau siv, kev txhawb nqa kev txiav txim siv 2 × 2 lim, segmentation txhawb, yoog raws QP kev ntsuas thiab hloov pauv hloov ntawm INTRA blocks.
