Release v3.1.0 Celestia

2021-05-03 v3.1.0
  This release adds an "all intra" mode to the encoder, which significantly
  speeds up the encoding of AVIF still images at speed 6.

- Upgrading:
    All intra mode for encoding AVIF still images and AV1 all intra videos:
    AOM_USAGE_ALL_INTRA (2) can be passed as the 'usage' argument to
    aom_codec_enc_config_default().

New encoder control IDs added:
      - AV1E_SET_ENABLE_DIAGONAL_INTRA: Enable diagonal (D45 to D203) intra
        prediction modes (0: false, 1: true (default)). Also available as
        "enable-diagonal-intra" for the aom_codec_set_option() function.

New aom_tune_metric enum value: AOM_TUNE_BUTTERAUGLI. The new aomenc option
    --tune=butteraugli was added to optimize the encoder’s perceptual quality by
    optimizing the Butteraugli metric. Install libjxl (JPEG XL) and then pass
    -DCONFIG_TUNE_BUTTERAUGLI=1 to the cmake command to enable it.

Addition of support for libvmaf 2.x.

- Enhancements:
    Heap memory consumption for encoding AVIF still images is significantly
    reduced.

- Bug fixes:
    Issue 2601: third_party/libaom fails licensecheck

Issue 2950: Conditional expression for rc->this_key_frame_forced is always
    true in find_next_key_frame()

Issue 2988: "make install" installs the aom.h header twice

Issue 2992: Incorrectly printing the temporal_id twice in dump_obu tool

Release v3.0.0 Braeburn

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.
