2021-03-23 v3.0.0 Braeburn

This release includes compression efficiency improvement, speed improvement
for realtime mode, as well as some new APIs.

  - Upgrading:

    Support for PSNR calculation based on stream bit-depth.

    New encoder control IDs added:
      - AV1E_SET_ENABLE_RECT_TX
      - AV1E_SET_VBR_CORPUS_COMPLEXITY_LAP
      - AV1E_GET_BASELINE_GF_INTERVAL
      - AV1E_SET_ENABLE_DNL_DENOISING

    New decoder control IDs added:
      - AOMD_GET_FWD_KF_PRESENT
      - AOMD_GET_FRAME_FLAGS
      - AOMD_GET_ALTREF_PRESENT
      - AOMD_GET_TILE_INFO
      - AOMD_GET_SCREEN_CONTENT_TOOLS_INFO
      - AOMD_GET_STILL_PICTURE
      - AOMD_GET_SB_SIZE
      - AOMD_GET_SHOW_EXISTING_FRAME_FLAG
      - AOMD_GET_S_FRAME_INFO

    New aom_tune_content enum value: AOM_CONTENT_FILM

    New aom_tune_metric enum value: AOM_TUNE_VMAF_NEG_MAX_GAIN

    Coefficient and mode update can be turned off via
    AV1E_SET_{COEFF/MODE}_COST_UPD_FREQ.

    New key & value API added, available with aom_codec_set_option() function.
    Scaling API expanded to include 1/4, 3/4 and 1/8.

  - Enhancements:

    Better multithreading performance with realtime mode.

    New speed 9 setting for faster realtime encoding.

    Smaller binary size with low bitdepth and realtime only build.

    Temporal denoiser and its optimizations on x86 and Neon.

    Optimizations for scaling.

    Faster encoding with speed settings 2 to 6 for good encoding mode.

    Improved documentation throughout the library, with function level
    documentation, tree view and support for the dot tool.

  - Bug fixes:
    Aside from those mentioned in v2.0.1 and v2.0.2, this release includes the
    following bug fixes:

    Issue 2940: Segfault when encoding with --use-16bit-internal and --limit > 1

    Issue 2941: Decoder mismatch with --rt --bit-depth=10 and --cpu-used=8

    Issue 2895: mingw-w64 i686 gcc fails to build

    Issue 2874: Separate ssse3 functions from sse2 file.

Release v2.0.0 Applejack

Release Candidate 1 for 2.0.0

AV1 Version 1.0.0 with errata 1 for AVIF

This tag does not indicate or imply any change to AV1 bitstream or
decoding behavior since v1.0.0-errata1, rather it indicates this
library can also be used for encoding and decoding AVIF.

AV1 Version 1.0.0 with errata 1

AOMedia Codec Workgroup Approved version 1.0

2016-04-07 v0.1.0 "AOMedia Codec 1"

just an early checkpoint, not an official release; the bitstream is
non-final and highly experimental.
