What happened?

On FLAC mount point its not showing the current song in icecast for some reason as you can see it on the picture. If i sream in FLAC its not sending metadata to the mount points at all and it titles "Unknown" for all.

Relevant log output

No response

Checked and this is my findings:
I have both a .mp3 and a .Flac mount point.
From the Docker Logs, AzuraCast has issues finding the Flac mount point and returns this in the logs:

Liquidsoap was also having issues with collecting the metadata, an update failed which lead to an error 400 and then returned an error.

After restarting the station I removed the .mp3 mount and retried the replication method.

Things that I noted: After the immediate restart, the server returned a unknown metadata, but after the playlist kicked in and the restart was completed, the metadata was correct.

With a .mp3 mount AND .flac mount, it returns the same errors that the server had no mount points listed.

Keep up the good work guys. Hopefully you can fix it in the next update.

@SC2Mitch Regarding the AzuraCast being unable to find the mount point errors, I think this is most likely related to LS taking some time to start streaming to the FLAC mount point of Icecast. Probably related to the broken pipe error. When I wait until LS connected correctly to the FLAC mount point and Icecast showing it on the :8000 status page AzuraCast can read the mount point data without getting an error.

In the latest Rolling-Release I can't see the Metadata update may have failed with error: 400, Bad Request (HTTP/1.0) message but I can see the other errors you mentioned:

In general Icecast (regardless of Icecast-kh or the original Icecast) does not support setting metadata for ogg/opus nor for ogg/flac.

See the open issues related to this on the Icecast-kh repo: https://github.com/karlheyes/icecast-kh/issues?q=is%3Aissue+is%3Aopen+ogg+flac

As well as this 11 years old Icecast issue: https://gitlab.xiph.org/xiph/icecast-server/-/issues/1655

When having at least 1 mount point that supports metadata (like mp3 for example) AzuraCast does correctly show what's currently playing though.

I have also tried removing the icy_metadata (this was added to prevent broken browser decoders like Chromes from stopping the stream of an ogg based one on each track change) and it's still looking the same although it seems like Chrome has now fixed their issue with ogg streams. Also tested Safari and Firefox, no stream stopping there too.

So we could remove the icy_metadata flag for ogg based streams to get in-stream metadata back for those. This would show metadata in players like VLC again which don't support icy metadata. Won't change the empty song title on Icecast though.

[bandiii92]

Main thing would be to show metadata when we stream in FLAC.

+1 here!

[luuk58]

Icecast now supports metadata in ogg/flac.

It's the master branch though, not the kh branch.

I have seen this too a few weeks ago but at the moment this is only available in a development branch of their repo and neither merged into their main branch nor released as a beta version. So even if we would switch to main Icecast (which we can't due to a missing feature that we need for correct listener reporting) we wouldn't get this feature yet.
