As seen on reddit, the Alliance for Open Media - AOM has released SVT-AV1 v. 2.3.0 The Scalable Video Technology for AV1 (SVT-AV1 Encoder) is an AV1-compliant software encoder library.
-
NEW FAST DECODE MODE -
New fast-decode (2) to allow for an average AV1 software cycle reduction of 25-50% vs fast-decode 0 with a 1-3% BD-Rate loss across the presets -
Improved fast-decode (1) option to increase its AV1 software cycle reduction by ~10% while maintaining the same quality levels -
Improved --lp settings for high resolutions, with CRF gaining a ~4% improvement in speed and VBR gaining ~15% -
Further Arm-based optimizations improving the efficiency of previously written Arm-neon implementations by an average of 30% -
Address speed regressions for high resolutions first pass encode by tuning the threading parameters, with 1080p showing the biggest gains -
Enabled AVX512 by default in cmake allowing for ~2-4% speedup
I hope system-wide nasm installed on Phyllis's build systems will cope with that .....
