- Update to version 3.4.0:
* This release includes compression efficiency and perceptual
quality improvements, speedup and memory optimizations, and
some new features. There are no ABI or API breaking changes in
this release.
* New Features:
- New --dist-metric flag with "qm-psnr" value to use
quantization matrices in the distortion computation for RD
search. The default value is "psnr".

all-intra encoding faster for high bit rate under
"--deltaq-mode=3" mode.
- New rate control library aom_av1_rc for real-time hardware
encoders. Supports CBR for both one spatial layer and SVC.
- New image format AOM_IMG_FMT_NV12 can be used as input to the
encoder. The presence of AOM_IMG_FMT_NV12 can be detected at
compile time by checking if the macro AOM_HAVE_IMG_FMT_NV12
is defined.
- New codec controls for the encoder:
o AV1E_SET_AUTO_INTRA_TOOLS_OFF. Only in effect if
--deltaq-mode=3.
o AV1E_SET_RTC_EXTERNAL_RC
o AV1E_SET_FP_MT. Only supported if libaom is built with
-DCONFIG_FRAME_PARALLEL_ENCODE=1.
o AV1E_GET_TARGET_SEQ_LEVEL_IDX
- New key-value pairs for the key-value API:
o --auto-intra-tools-off=0 (default) or 1. Only in effect if
--deltaq-mode=3.

o --fp-mt=0 (default) or 1. Only supported if libaom is built
with -DCONFIG_FRAME_PARALLEL_ENCODE=1.
- New aomenc options (not supported by the key-value API):
o --nv12
* Compression Efficiency Improvements:

to 0.6% coding gain.
- RTC at speed 9/10: BD-rate gain of ~4/5%

screen at speed 10 (quality, speedup, and rate control), up
to high resolutions (1080p).
- RTC-SVC: fixes to make intra-only frames work for spatial
layers.
- RTC-SVC: quality improvements for temporal layers.
- AV1 RT: A new passive rate control strategy for screen
content, an average of 7.5% coding gain, with some clips of
20+%. The feature is turned off by default due to higher bit
rate variation.

- RTC: Visual quality improvements for high speeds (9/10)
- Improvements in coding quality for all intra mode
* Speedup and Memory Optimizations:
- ~10% speedup in good quality mode encoding.

- Update to version 3.2.0:
* This release includes compression efficiency and perceptual
quality improvements, speedup and memory optimizations, as well
as some new features.
* New Features:
+ Introduced speeds 7, 8, and 9 for all intra mode.
+ Introduced speed 10 for real time mode.
+ Introduced an API that allows external partition decisions.
+ SVC: added support for compound prediction.
+ SVC: added support for fixed SVC modes.
* Compression Efficiency Improvements:
+ Intra-mode search improvement.
+ Improved real time (RT) mode BDrate savings by ~5% (RT speed
5) and ~12% (RT speed 6). The improvement was measured on the
video conference set.
+ Improved real time mode for nonrd path (speed 7, 8, 9):
BDrate gains of ~3-5%.
+ Rate control and RD adjustments based on ML research in VP9.
Gains of ~0.5-1.0% for HD.
* Perceptual Quality Improvements:
+ Added a new mode --deltaq-mode=3 to improve perceptual
quality based on a differential contrast model for still
images.
+ Added a new mode –deltaq-mode=4 to improve perceptual quality
based on user rated cq_level data set for still images.
+ Weighting of some intra mode and partition size choices to
better manage and retain texture.
* Speedup and Memory Optimizations:
+ Further improved 2-pass good quality encoder speed:
. Speed 2 speedup: 18%
. Speed 3 speedup: 22%
. Speed 4 speedup: 37%
. Speed 5 speedup: 30%
. Speed 6 speedup: 20%
+ Optimized the real time encoder (measured on the video
conference set):
. RT speed 5 speedup: 110%
. RT speed 6 speedup: 77%
* Bug Fixes
+ Issue 3069: Fix one-pass mode keyframe placement off-by-one
error.
+ Issue 3156: Fix a bug in av1_quantize_lp AVX2 optimization.
- Drop libaom-CVE-2021-30474.patch: Fixed upstream.
- Drop libaom-CVE-2021-30475.patch: Fixed upstream.
- Remove changesgenerate option from _service file, use data from
CHANGELOG to fill .changes instead as it it much nicer and human
readable than just a list of commit messages.

- Update to version 3.1.0 (bsc#1185843):
https://aomedia.googlesource.com/aom/+/refs/tags/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.
- Includes 3.0
https://aomedia.googlesource.com/aom/+/refs/tags/v3.0.0
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.

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.

- Enable CONFIG_LOWBITDEPTH. Makes 8-bit decoding faster. The only
reason this confusingly-named option is not enabled by default
is that its behavior might not match the 16-bit reference code
path, and that hardware vendors want to be able to validate
their designs against it. No actual mismatches have been found.
