Release v3.11.0 Minty
2024-11-14 v3.11.0 Minty
This release includes perceptual quality improvements, binary size reduction
under certain configurations and many bug fixes. This release changes the
default encoder configuration for the AOM_USAGE_REALTIME mode. This release
is ABI compatible with the last release.
- Perceptual Quality Improvements
* Visual quality improvements for RTC screen content
* Higher quality on scene or slide changes
* Faster quality ramp-up for static content after scene change
* Quality improvements for screen content with active maps
- Speedup
* Added and improved Neon SIMD paths for dynamic frame scaling with ~1.5%
overall encoding speedup.
- Other Improvements
* Binary size reduction: 10% compared with last release, with
CONFIG_REALTIME_ONLY enabled, CONFIG_AV1_DECODER and
CONFIG_AV1_HIGHBITDEPTH disabled.
* Update default_extra_cfg for CONFIG_REALTIME_ONLY to provide proper RTC
defaults settings
* Change the default valuess of the following encoder config options in the
AOM_USAGE_REALTIME mode:
* rc_overshoot_pct and rc_undershoot_pct are changed from 25 to 50
* rc_buf_sz is changed from 6000 to 1000
* rc_buf_initial_sz is changed from 4000 to 600
* rc_buf_optimal_sz is changed from 5000 to 600
