Live Radio: metadata

[Andrew_Lane]

Absolutely - I still need to default to J-River to listen to the 4 Radio Paradise FLAC streams with metadata & cover art so I know what is being played (and therefore can also be scrobbled) - if Roon can fix this in their radio stream it would make my transition to the Rooniverse 100%.

Thank you @Sebastien

Any clue ?

Hi Alec,

Not familiar at all with DietPi
Have you tried:

dietpi-software install 9

then

dietpi-software install 122

?

[Sebastien]

Seems I had some success after all

Well, quite a complex setup but at least it seems to work. Will provide an how-to tomorrow if I can find some time

[alec_eiffel (Rémi)]

Thank you but same issue with dietpi-software install x
Node-red simply doesn’t install. Maybe fixed with next DietPi update?
Will try tomorrow with Ubuntu.

[andybob (Andrew Cox)]

Wow !

Well done Sebastien.

Can you crisply describe what Roon and/or RP would have to do so that a normal Roon setup can see the same ?

[Sebastien]

Ok, here is my understanding - but note that I’m not an expert, so could be wrong.
To me, it looks it’s all about the streaming server.

1/ It seems that “icecast” is not able to embed metadata in OGG/Flac
2/ It sees on the opposite that another server, Rocket Streaming Audio Server, is able to do so
(I noticed this with your mention of Radio Bluesflac)
So my impression is that RP is streaming through icecast, and is therefore unable to add metadata.

It sounds to me that it would be “simply” a matter for RadioParadise to stream using Rocket Streaming Audio Server (RSAS) - at least the FLAC stream. And no action needed on Roon side.

If we want to workaround this, it is actually quite heavy:

• need to install our own instance of RSAS
• then, need to mirror the original RP stream to the newly installed RSAS; this is actually not as simple as for FIP (was icecast -> icecast), so I had to install something called LiquidSoap to do this (well, to be precise, RSAS can mirror another stream but does not allow to modify the metadata).
• and finally, grab and update the metadata, eg using node-red
  LiquidSoap, besides being a pain to install, is quite heavy and crashed my RPI, so I had to install it on an AWS EC2 instance…
  I’m preparing an how-to, it should take more or less half an hour to install all this.

@Sebastien

How-to in french for now, but is pretty straightforward. Let me know if you want to give it a try and if you need some support from my side

Afficher les informations “Now playing” de FIP sur Roon

J’ai découvert Roon (https://roonlabs.com/) il y a quelques mois. Si vous n’avez jamais entendu parler de Roon, il s’agit d’un logiciel vous permettant d’organiser et d’écouter votre musique favorite sur votre Mac/PC, iPhone, ainsi que sur votre…

@Sebastien i managed to make it work on an old PI3, under Ubuntu.

I had problems with PM2 it didn’t worked.

I think the overall npm / nodered / pm2 section can be replaced elegantly by the following as described here https://nodered.org/docs/getting-started/raspberrypi

sudo apt install build-essential git
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
sudo systemctl enable nodered.service 

Otherwise all was smooth

For DietPi there is an issue with the installation of Nodered, I’ll report it to Dan. Once this is fixed, it should work.

@Sebastien

It seems that “icecast” is not able to embed metadata in OGG/Flac

That was my understanding too, until I came across Mother Earth Radio - ogg/flac using Icecast 2.4.4 with metadata. Try it with VLC or foobar although Roon can’t extract it and stumbles at end of each track.
Status page here

[Sebastien]

That’s interesting. I spend some time in the source code of the latest version of icecast, and the method used to add the tag is not implemented for ogg format. So no clue how Mother Earth Radio could add metadata, unless if they’ve modified icecast source code maybe…

[BrianW (Brian)]

The server is (or says it is) 2.4.4. I can’t tell what streamer they use to send to the server.

As promised, the tutorial for “Now Playing” on Radio Paradise is available.
Note that it is quite more complex than for FIP, so it would be great if anyone volunteers to give it a try.

"Now Playing" info on Roon for Radio Paradise

[volpone]

@Sebastien

For FIP, there is quite an easy way to work around it, using a RPI, Icecast and node-red…

Perfect @Sebastien, thank’s a lot ! Node-Red is efficient.

Two questions:

• Do you know FIP Electro (and others FIP Web Radios) ICECAST and metadata URL’s to add new “relays” and “flows” ?
• RadioFrance’s metadata platform seems to provide cover art URLs, is there a way for ROON to display them ?

C’est tellement bien que l’on a envie de généraliser et d’enrichir le “Now Playing” avec les pochettes mais il y a peut être des limites techniques et juridiques du coté ROON…

Google translate:

It’s so good that we want to generalize and enrich the “Now Playing” with the covers but there may be technical and legal limits on the ROON side…

Rather than guess, we can check with @danny

[Sebastien]

Hi,

I have updated my post to include now all FIP webradios I’m aware of. Please have a try

[volpone]

Thank you, @Sebastien. It’s great to have the APIs for all FIP’s webradio. I’m gonna try (first version with FIP only is rock solid !).

[alec_eiffel (Rémi)]

Merci Sebastien !
For NodeRed installation: the steps you described didn’t work for me on a Pi3B under Ubuntu 20, see workaround in my last post above…
Good to have all FIPs with metadata now!

[volpone]

@alec_eiffel

the steps you described didn’t work for me on a Pi3B under Ubuntu 20, see workaround in my last post above…

+1 , OK with your workaround: https://nodered.org/docs/getting-started/raspberrypi

Here’s a link to all logos, feel free to add in your tutorial.
