v1.6.0 - 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 1-4% for the faster presets
Improve the tradeoffs for the low delay mode for both screen content and non-screen content encoding modes
Add a toggle to remove the legacy one-frame buffer at the input of the pipeline allowing 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

Strangely, except for being built into Handbrake (nightly) and ffmpeg I cannot finde recent "SvtAv1EncApp.exe" anywere for use with av1an or custom command lines.

And yes, I know about just-learn-to-compile-it-yourself so with me asking this isn't the answer.

Tested the ARM version of SVT-AV1 1.8.0 and it is as good as advertised. It is WAYYYY faster than the last one I tested (Version 1.4.1 released on 2022-12-12). HUGE progress made on the ARM front of the SVT-AV1 encoder within the space of just ONE year.
Many thanks to the AV1 development team.

I highly recommend you get media-autobuild-suite up and running to cut binaries for you

Does somebody know if there are plans to add support for YUV422 to SVT-AV1 ?
The only (outdated) information I found is this: https://www.phoronix.com/news/Intel-...-Decode-FFmpeg

Changelog

[2.0.0] - 2024-03-13

Major API updates

- Changed the API signaling the End Of Stream (EOS) with the last frame vs with an empty frame
- OPT_LD_LATENCY2 making the change above is kept in the code to help devs with integration
- Removed the 3-pass VBR mode which changed the calling mechanism of multi-pass VBR
- Moved to a new versioning scheme where the project major version will be updated everytime API/ABI is changed


Encoder

- Improve the tradeoffs for the random access mode across presets:
- Speedup presets MR by ~100% and improved quality along with tradeoff improvements across the higher quality presets (!2179)
- Improved the compression efficiency of presets M9-M13 by 1-4% (!2179)
- Simplified VBR multi-pass to use 2 passes to allow integration with ffmpeg
- Continued adding ARM optimizations for functions with c_only equivalent
- Replaced the 3-pass VBR with a 2-pass VBR to ease the multi-pass integration with ffmpeg
- Memory savings of 20-35% for LP 8 mode in preset M6 and below and 1-5% in other modes / presets


Cleanup and bug fixes and documentation

- Various cleanups and functional bug fixes
- Update the documentation to reflect the rate control changes
