Branch: CURRENT, Version: 3.3.0nb1, Package name: libaom-3.3.0nb1, Maintainer: pkgsrc-users

AOMedia Video 1 (AV1), is an open, royalty-free video coding format designed
for video transmissions over the Internet.
AV1 is intended to be able to be used together with the audio format Opus in a
future version of the WebM container format for HTML5 web video and WebRTC.

libaom: Update to 3.3.0

2022-01-28 v3.3.0
  This release includes compression efficiency and perceptual quality
  improvements, speedup and memory optimizations, some new features, and
  several bug fixes.

  - New Features
    * AV1 RT: Introducing CDEF search level 5
    * Changed real time speed 4 to behave the same as real time speed 5
    * Add --deltaq-strength
    * rtc: Allow scene-change and overshoot detection for svc
    * rtc: Intra-only frame for svc
    * AV1 RT: Option 2 for codec control AV1E_SET_ENABLE_CDEF to disable
      CDEF on non-ref frames
    * New codec controls AV1E_SET_LOOPFILTER_CONTROL and
      AOME_GET_LOOPFILTER_LEVEL
    * Improvements to three pass encoding

  - Compression Efficiency Improvements
    * Overall compression gains: 0.6%

  - Perceptual Quality Improvements
    * Improves the perceptual quality of high QP encoding for delta-q mode 4
    * Auto select noise synthesis level for all intra

  - Speedup and Memory Optimizations
    * Added many SSE2 optimizations.
    * Good quality 2-pass encoder speedups:
      o Speed 2: 9%
      o Speed 3: 12.5%
      o Speed 4: 8%
      o Speed 5: 3%
      o Speed 6: 4%
    * Real time mode encoder speedups:
      o Speed 5: 2.6% BDRate gain, 4% speedup
      o Speed 6: 3.5% BDRate gain, 4% speedup
      o Speed 9: 1% BDRate gain, 3% speedup
      o Speed 10: 3% BDRate gain, neutral speedup
    * All intra encoding speedups (AVIF):
      o Single thread - speed 6: 8%
      o Single thread - speed 9: 15%
      o Multi thread(8) - speed 6: 14%
      o Multi thread(8) - speed 9: 34%

  - Bug Fixes
    * Issue 3163: Segmentation fault when using --enable-keyframe-filtering=2
    * Issue 2436: Integer overflow in av1_warp_affine_c()
    * Issue 3226: armv7 build failure due to gcc-11
    * Issue 3195: Bug report on libaom (AddressSanitizer: heap-buffer-overflow)
    * Issue 3191: Bug report on libaom (AddressSanitizer: SEGV on unknown
      address)
    * Issue 3176: Some SSE2/SADx4AvgTest.* tests fail on Windows
    * Issue 3175: Some SSE2/SADSkipTest.* tests fail on Windows
