Intel offentliggjorde<\/a><\/noindex> udgiver biblioteket SVT-AV1 0.6<\/a><\/noindex> (Scalable Video Technology AV1), der tilbyder alternative kodere og dekodere til video kodningsformatet AV1, som udnytter de hardware-parallelle beregningsmuligheder, der findes i moderne Intel CPU'er. Hovedform\u00e5let med SVT-AV1 er at opn\u00e5 et pr\u00e6stationsniveau, der er egnet til on-the-fly videotranskodering og anvendelse i tjenester, der leverer video on demand (VOD). Koden udvikles inden for projektet OpenVisualCloud, som ogs\u00e5 udvikler kodere. SVT-HEVC<\/a><\/noindex> og SVT-VP9<\/a><\/noindex>, og distribueres<\/a><\/noindex> under BSD-licensen. <\/p>\n

For using SVT-AV1, a minimum of an Intel Core fifth-generation processor (Intel Xeon E5-v4 and newer CPUs) is required. To encode 10-bit AV1 streams at 4K quality, 48 GB of RAM is needed, for 1080p \u2014 16 GB, for 720p \u2014 8 GB, and for 480p \u2014 4 GB. Due to the complexity of the algorithms used in AV1, encoding in this format requires significantly more resources than other formats, which does not allow the standard AV1 encoder to be used for real-time transcoding. For example, the standard encoder from the AV1 project
\nkr\u00e6ver<\/a><\/noindex> requires 5721, 5869, and 658 times more computations compared to the x264 (main profile), x264 (high profile), and libvpx-vp9 encoders. <\/p>\n

Blandt \u00e6ndringerne i den nye udgave af SVT-AV1 bem\u00e6rkes tilf\u00f8jelsen af en tidlig implementering af dekoderen (tidligere blev kun kodning underst\u00f8ttet) og st\u00f8tte til statisk binding af biblioteker. Der er ogs\u00e5 implementeret nye SIMD-optimeringer, st\u00f8tte til decimering<\/a><\/noindex> using 2\u00d72 filters, support for segmentation, and adaptive capabilities QP-skalering<\/a><\/noindex> og adaptiv transformation af INTRA blokke.<\/p>\n
