So 3.1.0 supports opus? Well if so ill get on to my streaming company to get the support.
To get technical, Centova Cast isn't really involved in supporting Opus. But Centova Cast does support IceCast v2.4.0 and Liquidsoap, both of which DO support Opus. So in a roundabout way, yes.
But we can't really take the credit.
Checking IceCast ...
Not updated, skipping
[root@stream1 ~]# icecast -v
Icecast 2.3.2
Could be any number of things -- most likely though, you have 2.3.2 installed alongside 2.4.0. What does "/usr/local/icecast/bin/icecast -v" display? If it shows 2.4.0, then you're using 2.4.0 in Centova Cast.
