v3.4.0
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".
* New command line option "--auto-intra-tools-off=1" to make
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 --strict-level-conformance=0 (default) or 1
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
* Correctly calculate SSE for high bitdepth in skip mode, 0.2% to
0.6% coding gain.
* RTC at speed 9/10: BD-rate gain of ~4/5%
* RTC screen content coding: many improvements for real-time 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.
- Perceptual Quality Improvements
* 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.
* ~7% heap memory reduction in good quality encoding mode for speed
5 and 6.
* Ongoing improvements to intra-frame encoding performance on Arm

~10% speedup for speed 9/10 in real time encoding mode
* ~20% heap memory reduction in still-picture encoding mode for
360p-720p resolutions with multiple threads
* ~13% speedup for speed 6 and ~12% speedup for speed 9 in
still-picture encoding mode.
* Optimizations to improve multi-thread efficiency for still-picture
encoding mode.

most of these simply extend matching from "aarch64" to "aarch64eb"
in various forms of code. most remaining uses in pkgsrc of
"MACHINE_ARCH == aarch64" are because of missing aarch64eb support,
such as most of the binary-bootstrap requiring languages like rust,
go, and java.
no pkg-bump because this shouldn't change packages on systems that
could already build all of these.
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.
