Compania Intel a publicat<\/a><\/noindex> a lansat biblioteca SVT-AV1 0.6<\/a><\/noindex> (Tehnologia Video Scalabil\u0103 AV1) ofer\u0103 un codificator \u0219i un decodificator alternativ pentru formatul de codare video AV1, care utilizeaz\u0103 resursele de procesare paralele prezente \u00een CPU-urile Intel moderne. Obiectivul principal al SVT-AV1 este de a atinge un nivel de performan\u021b\u0103 adecvat pentru re-codificarea video \u00een timp real \u0219i utilizarea \u00een servicii de video la cerere (VOD). Codul este dezvoltat \u00een cadrul proiectului OpenVisualCloud, care dezvolt\u0103 de asemenea codificatoare. SVT-HEVC<\/a><\/noindex> \u0219i SVT-VP9<\/a><\/noindex>, \u0219i se r\u0103sp\u00e2nde\u0219te<\/a><\/noindex> sub licen\u021ba BSD. <\/p>\n

Pentru a utiliza SVT-AV1 este necesar un procesor Intel Core de genera\u021bie a cincea (Intel Xeon E5-v4 \u0219i CPU-uri mai recente). Pentru codificarea stream-urilor AV1 de 10 bi\u021bi cu calitate 4K sunt necesari 48 GB RAM, 1080p \u2014 16 GB, 720p \u2014 8 GB, 480p \u2014 4 GB. Datorit\u0103 complexit\u0103\u021bii algoritmilor aplica\u021bi \u00een AV1, codificarea acestui format necesit\u0103 cu mult mai multe resurse dec\u00e2t alte formate, ceea ce nu permite utilizarea encoderului AV1 standard pentru transcodare \u00een timp real. De exemplu, encoderul standard de la proiectul AV1
\nrequiere<\/a><\/noindex> a necesitat de 5721, 5869 \u0219i 658 de ori mai multe calcule comparativ cu encoderele x264 (profil \u201emain\u201d), x264 (profil \u201ehigh\u201d) \u0219i libvpx-vp9. <\/p>\n

Printre modific\u0103rile din noua versiune SVT-AV1 se num\u0103r\u0103 ad\u0103ugarea unei implement\u0103ri ini\u021biale a decodificatorului (anterior era suportat\u0103 doar codificarea) \u0219i suportul pentru legarea static\u0103 a bibliotecii. De asemenea, au fost implementate noi optimiz\u0103ri SIMD, suport pentru decimare<\/a><\/noindex> cu utilizarea filtrului 2\u00d72, suport pentru segmentare, capacitate adaptiv\u0103 scal\u0103rii QP<\/a><\/noindex> \u0219i a transform\u0103rii adaptive a blocurilor INTRA.<\/p>\n
