Full Changelog: p20210803...p20210810

Changes

• Speed levels had been retuned
• RDO-Lookahead is now speed-level dependent by default
• --help now shows colors
• Unify spatial and temporal adaptive quantization
  • The encoding time is reduced by 52.61% at speed level 0.
  • General 3~6% improvement in BD-Rate
• The encoders would use the global threadpool unless configured otherwise
  • Allows to use rayon if wasm is built with atomics support
• Scene-change logic improvement, now it faster and better.
  • Overall 1~2% faster
  • Around 1% improvement in BD-Rate
• Import ASM from dav1d 0.8.1, 0.8.2, 0.9.0, 0.9.1 for AVX2, SSE2, SSE3, NEON.
  • More than 50% improved encoding times for 10bit files.

Fixes

• Initialize residual when less than the transform width is visible.
  • This fixes the squared artifacts and incorrectly encoded edge of a frame, this was particularly evident for still images.
• Correctly align the memory when using AVX512.

New features

• by-gop parallel encoding is available as part of the channel-api
• no-scene-detection encoding option
• Make sure the dequantize tests do not use random values outside the possible range.
• v_frame provides now a simple downscaler.
