Release Notes:

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 values 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

  - Bug Fixes
    * aomedia:363016123: rtc: Fix setting of intra-only frame for
      set_ref_frame_config and add checks
    * aomedia:42302583: rtc: Fix for artifacts for screen with active_maps
    * b:365088425: rtc: Allow for lower-QP on scene/slide changes
    * b:367285382: Fix to encoder quality max-out too early for screen
    * b:362936830: rtc: Allow QP to decrease more aggressively for static
      content
    * b:361617762: Clamp the calculation of sb64_target_rate to INT_MAX
    * chromium:362123224: rtc-svc: Reset ref_map_idx for references not used
    * chromium:367892770: Fix to possible integer overflow in reset_rc
    * webrtc:369633254: rtc-svc: Fix to reset ref_idx for svc
    * Fix exit condition in rate correction update
