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 Issue 2998: Issue 2999: Issue 3000: -

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. - 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. -
