Here is an update to SVT-AV1 1.8.0.
## [1.8.0] - 2023-12-11 Encoder - Improve the tradeoffs for the random access mode across presets: - Speedup CRF presets M6 to M0 by 17-53% while maintaining similar quality levels - Re-adjust CRF presets M7 to M13 for better quality with BD-rate gains ranging from 1-4% - Improve the quality and speed of the 1-pass VBR mode - More details on the per preset improvements can be found in MR !2143 - Add API allowing to update bitrate / CRF and Key_frame placement during the encoding session for CBR lowdelay mode and CRF Random Access mode - ARM Neon SIMD optimizations for most critical kernels allowing for a 4.5-8x fps speedup vs the c implementation Cleanup and bug fixes and documentation - Various cleanups and functional bug fixes - Update the documentation for preset options and individual features ## [1.7.0] - 2023-08-23 Encoder - Improve the tradeoffs for the random access mode across presets MR-M13: - Quality improvements across all presets and metrics ranging from 0.3% to 4.5% in BD-rate (!2129) - Spacing between presets [M1-M6] has been adjusted to account for the tradeoff improvements achieved - As a user guidance when comparing v1.7 vs v1.6 in a convexhull encoding setup: - v1.7.0 M2 is now at similar quality levels as v1.6.0 M1 while being ~50% faster - v1.7.0 M3 is now at similar quality levels as v1.6.0 M2 while being ~50% faster - v1.7.0 M4 is now at similar quality levels as v1.6.0 M3 while being ~40% faster - v1.7.0 M5 is now at similar quality levels as v1.6.0 M4 while being ~30% faster - v1.7.0 M6 is now at similar quality levels as v1.6.0 M5 while being ~25% faster - Added an experimental tune SSIM mode yielding ~3-4% additional SSIM BD-rate gains (!2109) Build, cleanup and bug fixes - Various cleanups and functional bug fixes - Fix build conflict with libaom ## [1.6.0] - 2023-06-18 Encoder - Improve the tradeoffs for the random access mode across presets M1-M13: - Speeding up the higher quality presets by 30-40% - Improving the BD-rate by 1-2% for the faster presets - Improve the tradeoffs for the low delay mode for both scrren content and non-screen content encoding modes - Add a toggle to remove the legacy one-frame buffer at the input of the pipeline alowing the low delay mode to operate at sub-frame processing latencies - Add a new API allowing the user to specify quantization offsets for a region of interest per frame Build, cleanup and bug fixes - Various cleanups and functional bug fixes - Fix the startup minigop size BD-rate loss - Add ability to run the ci-testing offline Index: Makefile =================================================================== RCS file: /cvs/ports/multimedia/svt-av1/Makefile,v retrieving revision 1.15 diff -u -p -u -p -r1.15 Makefile --- Makefile 27 Sep 2023 10:10:22 -0000 1.15 +++ Makefile 29 Feb 2024 04:05:06 -0000 @@ -2,7 +2,7 @@ ONLY_FOR_ARCHS= ${LP64_ARCHS} i386 COMMENT= scalable AV1 encoder/decoder -VER= 1.5.0 +VER= 1.8.0 DISTNAME= SVT-AV1-v${VER} PKGNAME= svt-av1-${VER} CATEGORIES= multimedia Index: distinfo =================================================================== RCS file: /cvs/ports/multimedia/svt-av1/distinfo,v retrieving revision 1.12 diff -u -p -u -p -r1.12 distinfo --- distinfo 30 Apr 2023 11:54:30 -0000 1.12 +++ distinfo 29 Feb 2024 04:05:06 -0000 @@ -1,2 +1,2 @@ -SHA256 (SVT-AV1-v1.5.0.tar.bz2) = pkmwcZBvuEDfGfsOLsl8BP3oLI7WTfuGYvYly4vGJF4= -SIZE (SVT-AV1-v1.5.0.tar.bz2) = 9490521 +SHA256 (SVT-AV1-v1.8.0.tar.bz2) = QccYO+maLHJlaxX7pABeRsmYzTRkGFA+0pbFq+ZILkc= +SIZE (SVT-AV1-v1.8.0.tar.bz2) = 9585789
