Metadata in FLAC streams

[d6jg]

Are you talking about updates during flac stream? If you do, be aware that flac does not support that. It's not a limitation of the player but of flac itself. Now, you should use flac in an ogg container and that will do.

Sorry should have been clearer, it is FLAC in an Ogg container.

Well, this is a good question and to my real shame I had to look

So in case of RP streams, this is the plugin that polls the RP url to know what's on, there is no processing of any kind for oggflac in squeezelite... maybe something to develop!

[edit]: and I'll have to better read the ogg documentation if metadata can be placed alongside stream. But in your case, I think if you can add icy support in your radio server, that will for sure bring back metadata (with no help from a plugin) whether you're proxied or not. As @bpa said, with icy, squeezelite finds it and reports back to LMS which in return grabs things like artwork. The icy format is super simple http://ample.sourceforge.net/developers.shtml

You have misunderstood slightly Philippe.

On my 64bit production server the FLAC/OGG stream connects and I DO GET metatdata updates. This is with SB hardware player or pCp squeezelite players.
On my 2 x Pi servers the FLAC/OGG stream connects and I get initial metadata (current song) on built in Squeezelite player but it does NOT update.
What I am saying is that there is some difference between LMS or Squeezelite on 64bit Linux and 32bit tinyCore Linux.
I have not yet had a chance to try any SB hardware player with the Pi's.

I think the fact it is MY Radio Station is actually irrelevant. Its just an Icecast server sending FLAC in an Ogg container.

PS. I was comparing the non plugin RP stream at http://stream.radioparadise.com/flacm
PPS. Yes longer term I shall be looking at a plugin.

It’s probably too late for me on this side of the earth but that is really strange. Icecast are exactly servers that can or cannot sens such ICY metadata. Then player respond if they accept it. Because there is zero metadata sent back my any squeezelite except for icy
When you have metadata. Is the SB involved in the playback? Because if you have transcoding, it might be a different story. Ogf I don’t think is supported by SB so you’ll default to something else then and this could explain

No SB involved in the Playback.
Production Server (64bit) - plays on everything and gets Metadata Ok whether SB player or Squeezelite.
Pi (32bit) - so far I can only test with Squeezelite and this gets initial data but no update (whether direct or proxied).

2 other things.
The playout server is actually Rocketbroadcaster (RSAS) which is a drop in replacement for Icecast and uses all of the Icecast config but since the handling on the Production server is perfect I don't think it is that.
Ogg/Flac settings on all 3 servers are the same

Same software versions on all ends?

I remember taking a look at flac/ogg metadata for someone else recently.
I found the small number of places where LMS handles OGG metadata but after increasing log levels I could not get it to show anything as the data changed.
Playing the same stream in foobar2000 showed the metadata changing.

I was away from home at the time and could not dig deeply.

I'd say it's pretty clear what you're supposed to do... :-) Go straight
to the latest build available for both of them. The keyword "flac" shows
up in five different commits between your older build and latest. They
could be relevant.

Noted. I will get 3 servers at identical LMS levels and some hardware and squeezelite players on each and re-test.
