La empresa Intel ha publicado<\/a><\/noindex> ha lanzado la biblioteca SVT-AV1 0.6<\/a><\/noindex> (Tecnolog\u00eda de Video Escalable AV1), que proporciona codificadores y decodificadores alternativos para el formato de codificaci\u00f3n de video AV1, utilizando las capacidades de paralelizaci\u00f3n de los c\u00e1lculos presentes en las CPU modernas de Intel. El objetivo principal de SVT-AV1 es alcanzar un nivel de rendimiento adecuado para la recodificaci\u00f3n de video en tiempo real y su utilizaci\u00f3n en servicios de video bajo demanda (VOD). El c\u00f3digo se desarrolla en el marco del proyecto OpenVisualCloud, que tambi\u00e9n desarrolla codificadores. SVT-HEVC<\/a><\/noindex> y SVT-VP9<\/a><\/noindex>como se distribuye<\/a><\/noindex> bajo licencia BSD. <\/p>\n

Para utilizar SVT-AV1 se requiere, como m\u00ednimo, un procesador Intel Core de quinta generaci\u00f3n (Intel Xeon E5-v4 y CPUs m\u00e1s nuevos). Para codificar flujos AV1 de 10 bits con calidad 4K se necesitan 48 GB de RAM, 16 GB para 1080p, 8 GB para 720p y 4 GB para 480p. Debido a la complejidad de los algoritmos aplicados en AV1, la codificaci\u00f3n de este formato requiere significativamente m\u00e1s recursos que otros formatos, lo que impide el uso del codificador AV1 est\u00e1ndar para la recodificaci\u00f3n en tiempo real. Por ejemplo, el codificador est\u00e1ndar del proyecto AV1
\nrequiere<\/a><\/noindex> requiere 5721, 5869 y 658 veces m\u00e1s c\u00e1lculos en comparaci\u00f3n con los codificadores x264 (perfil 'main'), x264 (perfil 'high') y libvpx-vp9. <\/p>\n

Entre los cambios en la nueva versi\u00f3n de SVT-AV1, se destaca la adici\u00f3n de una implementaci\u00f3n inicial del decodificador (anteriormente solo se soportaba la codificaci\u00f3n) y el soporte para el enlace est\u00e1tico de la biblioteca. Tambi\u00e9n se han implementado nuevas optimizaciones SIMD y soporte para decimaci\u00f3n<\/a><\/noindex> usando filtros 2\u00d72, soporte para segmentaci\u00f3n, capacidad adaptativa escalaci\u00f3n QP<\/a><\/noindex> y transformaci\u00f3n adaptativa de bloques INTRA.<\/p>\n
