![]() ![]() We’ll show you how to turn it on and what are the effects. It’s little known, but x265 does not actually use AVX-512 by default. We looked at one use: encoding HEVC video via x265. One area where AVX-512 promises better performance is multimedia. The 11th generation Intel Core processors (Rocket Lake) are the first mainstream desktop parts supporting AVX-512 instruction set, previously only available in Xeons or the X299 platform.

NOTE: Windows users, please make sure to install. Improved parity with the Mac and Windows graphical interfaces.Added many quality of life improvements contributed by community members.oneVPL 2023.1.0 (Intel QSV encoding/decoding).libjpeg-turbo 2.1.4 (preview image compression).liblzma (xz) 5.2.6 (LZMA video decoding, e.g.Miscellaneous bug fixes and improvements.Added -lto configure parameter to enable link time optimization.Added -cpu configure parameter to enable building for native CPU architecture.Updated the following filters to support higher than 8-bit content and 4:2:2/4:4:4 chroma subsampling Improved multithread performance (slightly) for the following filters on high core count systems.Use zscale (zimg) by default, falling back to swscale where necessary.Improved video scaling performance on Apple Silicon and ARM-based systems.Higher accuracy on mixed aspect ratio content, e.g.Removed support for Intel CPUs older than 6th generation (Skylake) when using Intel Quick Sync Video.Fixed longstanding issue where slowest NVENC encoder preset caused encoding failures.Added support for Intel Deep Link Hyper Encode (leverage multiple QSV media engines to increase performance).Added H.265 4:2:2 profile for VideoToolbox encoder on Apple Silicon.Added H.264 levels 6, 6.1, and 6.2 for the x264 encoder.Added SVT-AV1 (software) and Intel QSV AV1 (hardware) video encoders.Related, the Theora encoder is long deprecated and will be removed in a future release. ![]()
