Description Mark 2024-03-04 23:32:10 UTC 
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

But that said, I appreciate the excitement, and I'll see if I can look at it tonight.

    media-libs/opus: activate new options in 1.5.1
    
    Activate new options mentioned in https://opus-codec.org/demo/opus-1.5/.
    
    They all have runtime toggles and can be overridden via MYMESONARGS if people
    really need.
