multimedia/libaom: Update to 3.10.0
Changelog:
2024-08-27 v3.10.0
This release includes new codec interfaces, compression efficiency and
perceptual improvements, speedup and memory optimizations and many bug
fixes. This release is ABI compatible with the last release.
The definitions of the internal macros AOM_INLINE and AOM_FORCE_INLINE
have been removed from the public header aom/aom_integer.h.
- New Features
* New codec controls:
* AV1E_SET_AUTO_TILES
* AV1E_GET_HIGH_MOTION_CONTENT_SCREEN_RTC
* AV1E_SET_POSTENCODE_DROP_RTC: Post encode frame drop feature.
* AV1E_SET_MAX_CONSEC_FRAME_DROP_MS_CBR
* New key-value pair for aom_codec_set_option():
* "auto-tiles": equivalent to the new codec control
AV1E_SET_AUTO_TILES.
- Deprecated Features
* Deprecated codec control:
* AV1E_SET_MAX_CONSEC_FRAME_DROP_CBR: Use the new codec control
AV1E_SET_MAX_CONSEC_FRAME_DROP_MS_CBR instead.
* The sframe_mode field in the aom_codec_enc_cfg_t struct is not
implemented.
- Compression Efficiency Improvements
* BD-rate gain of 0.7 - 1.3% (by enabling global motion tool) for
speed 5 and speed 6 with ~5% encode time increase.
* RTC speed 11 video: ~3-5% BD-rate gain for VGA and QVGA.
- Perceptual Quality Improvements
* RTC quality improvements for slide changes and scrolling content.
- Speedup and Memory Optimizations
* RTC screen content speedups:
* ~2x speedup for high motion content for speed 11.
* ~2x speedup on key frame coding for speed >= 10.
* Arm: Significant uplifts in speed in this release (vs v3.9.1) have
come from tuning the various convolutions according to filter size
(doing 8-tap when only 2-tap is required is inefficient) and also
deploying Armv8.6 USMMLA instructions in 6-tap and 12-tap standard
bitdepth convolutions.
* Standard bitdepth RTC:
* speed 5: +5%
* speed 6: +4%
* speed 7: +5%

* speed 9: +6%
* speed 10: +6%
* Standard bitdepth VoD:
* speed 0: +9%
* speed 1: +12%
* speed 2: +9%
* speed 3: +3%
* speed 4: +3%
* speed 5: -9% (expected due to global motion changes)
* speed 6: -3% (expected due to global motion changes)
* High bitdepth VoD:
* speed 0: +4%
* speed 1: +19%
* speed 2: +23%
* speed 3: +1%
* speed 4: +1%
* speed 5: -8% (expected due to global motion changes)
* speed 6: -3% (expected due to global motion changes)
* Standard bitdepth 2x1 horizontal super-resolution/scaling
encoding: +101%
- Other Improvements

libaom: updated to 3.4.0
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
* Faster encoding speed for "--deltaq-mode=3" mode.
* ~10% speedup for speed 5/6, ~15% speedup for speed 7/8, and
~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.

libaom: un-break the build: correct a patch so it applies
Fix libaom so that it at least builds on NetBSD/powerpc. No dynamic CPU feature detection so far on NetBSD/powerpc.
libaom: update to 3.2.0 2021-10-13 v3.2.0 This release includes compression efficiency and perceptual quality improvements, speedup and memory optimizations, as well as some new features.
multimedia: Replace RMD160 checksums with BLAKE2s checksums All checksums have been double-checked against existing RMD160 and SHA512 hashes The following distfiles could not be fetched (for legal reasons?): ./multimedia/adobe-flash-player/distinfo adobe-flash-player-32.0.0.465/flash_player_npapi_linux.i386.tar.gz ./multimedia/adobe-flash-player/distinfo adobe-flash-player-32.0.0.465/flash_player_npapi_linux.x86_64.tar.gz ./multimedia/libdvdcss/distinfo libdvdcss-1.4.3.tar.bz2
libaom: Switch to upstream's promised-stable distfile. Sorry for the churn.
libaom: use MASTER_SITE_LOCAL, distfile checksum is not stable
libaom: Do not revbump itself and update checksum * aomedia.googlesource.com returns another tarball.
libaom: update to 3.1.3 This includes various bug fixes and improvements to the encoder.
multimedia: Remove SHA1 hashes for distfiles
libaom: Fix the build for NetBSD/*arm*
Write correct version number in aom.pc file, bump PKGREVISION This change is required to build multimedia/ffmpwg4-4.1.
libaom: do not build tools nor docs (these are not installed anyway); fix linking
libaom: Fix build on SunOS.
Use a file name with web browser download, and update checksum However #MASTER_SITES link returns a distfile with various checksums. I have uploaded my distfile to MASTER_SITE_LOCAL and update MASTER_SITES.
Add libaom version 1.0.0 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.
