[Icecast-dev] OPUS/FLAC Metadata

[Eduardo Martinez]

Hi Phillipp,

I don't think there is a ticket open about FLAC metadata specifically.  The
original thread from 2015 is as follows:

Yes. That is correct. Thank you for reporting.
We have recently worked on improving the metadata support a bit and also
talked about better support on Opus and FLAC on the international
Icecast meeting this year.

To the other project members:
Is there a ticket for this? if not can someone create a meta ticket with
child tickets per codec? When there is a ticket please also ping me on
IRC. Thank you."
