OP25 Liquidsoap 2.2.4-1+dev possible fix?

[telvana]

Greetings,

As some may already know, liquidsoap does not function properly due to recent changes by the team at Liquidsoap. The issue becomes apparent when one updates past a certain version of liquidsoap (not sure which version, but the issue occured to me after trying to use it on Debian 12 or Ubuntu 24.04.1). The fix was pretty simple, really, all that needed changed was removing "icy_metadata="false"". I am not saying this will solve it for everyone else, but this worked for me.

So then the question becomes whether I should simply remove "icy_metadata" from the default configuration in the gr310 branch? That would be easy enough to accomplish, but does it impact compatibility with earlier versions?

Good question, I don't have an easy way to test it right now, but I can spin up a VM over the weekend and test it out, unless someone else has a working copy that's running on the older version that they'd be willing to try it out on

I am running an instance of op25 with Liquidsoap v2.2.4-1 on Ubuntu 24.04.1 can confirm the required change in the structure of
the output.icecast operator.
