Shouldn’t there be a codec_opus-21?
From Sangoma there is one:
https://downloads.digium.com/pub/telephony/codec_opus/asterisk-21.0/x86-64/
Otherwise you’ll have to be more specific about what you mean/have encountered. I just installed 21 with it selected, it downloaded the 21 version, and the module loaded.
There’s no 32 bit version. That’s what I needed so it failed. Opus version 20 (32 bit) worked fine.
Ah, you’re still on a 32-bit environment. I’ll make an issue.
