v2.1.0

Hi again! We're just barely trailing mainline's recent release to announce some exciting new changes in SVT-AV1-PSY v2.1.0! 🎉

PSY Updates

Documentation

• Additional PNG images have been transcoded to WebP
• Variance boost docs feature AVIF & WebP images
• Added Staxrip to featured projects in README. Welcome aboard!

Bug Fixes

• Removed ANSI escape color sequences for Windows builds (#46)

Other

• This major release doesn't have a micro-release letter, & is just labelled PSY Release: N/A - if we're doing a release in line with mainline, PSY release lettering will start at N/A & progress to A, B, etc from there.

Mainline Updates

API updates

• One config parameter added within the padding size. Config param structure size remains unchanged
• Presets 6 and 12 are now pointing to presets 7 and 13 respectively due to the lack of spacing between the presets
• Further preset shuffling is being discussed in #2152

Encoder

• Added variance boost support to improve visual quality for the tune vq mode
• Improve the tradeoffs for the random access mode across presets:
• Speedup of 12-40% presets M0, M3, M5 and M6 while maintaining similar quality levels
• Improved the compression efficiency of presets M11-M13 by 1-2%
• Added ARM optimizations for functions with c-only equivalent

Cleanup, build, bug fixes & documentation

• Use nasm as a default assembler and yasm as a fallback
• Fix performance regression for systems with multiple processor groups
• Enable building SvtAv1ApiTests and SvtAv1E2ETests for ARM
• Added variance boost documentation
• Added a mailmap file to map duplicate git generated emails to the appropriate author

Thanks for using SVT-AV1-PSY! ♥️
