Interestingly: | Code: | pckllbin opus
-rwxr-xr-x 1 root root 5363496 avril 8 17:38 /usr/lib64/libopus.so.0.10.0

Total size : 1.06 MiB |
| Code: | USE="-custom-modes -debug -doc -hardened -static-libs -test" ABI_X86="-32 (64) (-x32)" CPU_FLAGS_X86="sse"-Wa,-mbranches-within-32B-boundaries

Plz note "-Wa,-mbranches-within-32B-boundaries" badly increases binary size here.
Hoping this is for the best... 
Thks 4 ur attention, interest & support.

| That seems like a major flag changed, such as removal of debug symbols or switching from -O0 to -O2. |

What ever the cause is, not on my side IIRC.
Do you have any numbers to share by chance?

You may be right  | Code: | diff /var/db/repos/gentoo/media-libs/opus/opus-1.5.1-r1.ebuild /var/db/repos/gentoo/media-libs/opus/opus-1.5.2.ebuild

< -Denable-deep-plc=true
< -Denable-dred=true
< -Denable-osce=true
|
is evidently a thing.
repo/gentoo.git: | Code: | media-libs/opus: bump to 1.5.2
also removed runtime toggles from the ebuild as they are not in the meson file anymore |
Time to wonder what functional loss underlies there? ( i.e. AFA conversion is concerned dor my usecase, if any )
