CLI for notification of change in metadatas

Hello,

https://forums.slimdevices.com/showt...=1#post1044890

To get the title I send

title ?

Now I would like the get the new title/or radio name, or... when it arrive.
How to get automatic notification or sending a new message when the track or radio station changes ?

Thanks

A way to start but reading the CLI doc is the way to get what you want.

"listen 1" command - start a dump of lots of actions. Subscribe is more specific.
An output "playlist newsong" tells new track is starting - then you can enquire for album and artist details.

Example - commands in red. The following is test using Tidal - you have to investigate for other stations / files.

[color=red]listen 1[/color]
listen 1

Thanks bpa,

I'll investigate about listen (all informations but need to be parsed) and subscribe (playlist newsong; it's ok for when new song is coming but seems that the radio name is into the same feed).

but seems that the radio name is into the same feed

.
I don't use CLI in detail so all I am doing is guessing based on other LMS knowledge.

When a "newsong" starts playing - if it is a radio station the metadata may not be available immediately as it may be inline (i.e. mixed in with audio data) or via polling and it takes time before the metadata chunk is received.
So initially the metadata may just be station Name and then when metadata becomes available Title/Artist/Album will be updated so after notification of "newsong" keeping looking at Title,Artist,Album regularly because when a track changes on same station (i.e. metadata changes) there may not be a "playlist newsong"

It should be very close to what you see on a real player with a screen or a controller (like Jivelite).

What do you see there?

It might be that the previous song has finished playing and the new song title is not known.

You could look for " - " (%20-%20) and if not present then do something else.

In that case, If you do not want the radio station name to appear then what do you want to show instead?

Edit: started writing before bpa's reply appeared

The "newsong" text is the same as displayed on the touchscreen.


I founded the song name is: playlist newsong
and for the radio station: playlist newsong Radio

dc%3Aa6%3A32%3A75%3A45%3A0a playlist newsong ONE%20REPUBLIC%20-%20SUNSHINE

dc%3Aa6%3A32%3A75%3A45%3A0a playlist newsong Radio%20Pilatus 0

By this way I can parse the title and the radio name.

Solved !
Thanks
