opus 1.5.1 was released: https://opus-codec.org/demo/opus-1.5/ They write that it remains compatible but offers many new features, including machine learning features with build time switches and use of CPU extensions, that probably require a new USE flag. "Opus now has support and run-time detection for AVX2" "We have been careful to avoid huge models [...], most users should not notice the extra cost, but people using older (5+ years) phones or microcontrollers might. For that reason, all new ML-based features are disabled by default in Opus 1.5. They require both a compile-time switch (for size reasons) and then a run-time switch (for CPU reasons)." It looks like these are the configure options (I have not compared with 1.4, just guessing): --enable-dred Use Deep REDundancy (DRED) --enable-deep-plc Use deep PLC for SILK --enable-osce-training-data enables feature output for SILK enhancement --enable-osce enables speech coding enhancement Regarding the size: the .so of 1.4 is about 344K, the .so of a manual (stripped) build of 1.5.1 is about 5MB. The configure run detected AVX2 automatically: Intrinsics Optimizations: ...... x86 SSE SSE2 SSE4.1 AVX2 Run-time CPU detection: ........ x86 SSE4.1 AVX2 Reproducible: Always
