This is because "GitHub Pages created after June 15, 2016 and using github.io domains are served over HTTPS." and an LMS that I tried had problems accessing. So - was that an issue with old LMS (it was a 7.7 build) or is it a more general problem that could happen with more modern installations as well? What platform are you running LMS on?

Yes - am caching the meta data from the station (15 seconds but might extend it because of this) and also what I think the client already thinks is playing so that I don't push it too often.

One thing though - I use registerProvider and my provider routing is called once a second when the player is an SB2. Is this expected behaviour? Not 100% sure, but yes, probably expected behaviour. The SB2 is stupid, and LMS is feeding its display. Very well possible that some code is polling the plugin whenever the server is preparing a display update. Make sure you cache data in memory to reduce the load. -- Michael ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

I've got things working when there is more than one player that is playing the same station by not synced in LMS.

Thanks - that was the route I was going down and I found similar code in
Slim/Plugin/RemoteLibrary/ProtocolHandler.pm
My version in my timer return code is now something like this - and it
works
Code:
sub timerReturn {
my ( $client, $url ) = @_;
my $station = ( $url );
my $song = $client->playingSong();
my $playingURL = "";
if ( $song && $song->streamUrl ) { $playingURL = $song->streamUrl}
if ($playingURL ne $url){
# Given stream URL not the same now as we had before implies
listener has changed station
main::DEBUGLOG && $log->is_debug && $log->debug("$station -
timerReturn - stream changed to $playingURL");
# However, it might be an alternative that leads to the same
station (redirects) or another in the family so check
$station = ( $playingURL );
} else {
# If streamUrl not found then something is odd - so report it
to help determine issue
if (!$song || !$song->streamUrl || !$song->streamUrl ne ""){
# Odd?
main::DEBUGLOG && $log->is_debug &&
$log->debug("$station - timerReturn - streamUrl issue $playingURL");
}
}
if ($station ne "") {#One of mine so check for isPlaying and action it
...} else { # not mine - log it }
Odd thing is that none of the debug lines come out if switching from
streaming to playing local music - so I assume that the core code does a
killTimers in that situation.

Re: [SlimDevices: Plugins] Using plugin to get Internet radio track data from web site
Is there a recommended way to check that my plugin still "owns" the client? Keep track of the URL playing. If it has changed when your timer triggers, then don't do anything. Alternative approach could be a registration to be called on stop/pause/switch-away then I could killtimers - but I have not found a registration like that. subscribe takes commands as arguments. You might want to listen to "playlist play/stop/pause" etc. -- Michael ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
Re: [SlimDevices: Plugins] Using plugin to get Internet radio track data from web site
and another one ... sorry ... but one issue with using timers is that they can return after the listener has changed stations. So the "traditional" check of client->isPlaying is not enough ... since the client object represents the player and it is now playing a different station.

However, and odd thing is that LMS web Ui shows the correct Now Playing info for both client 1 and client 2 even though client 2 physical device sticks with the first set that I sent on its stream starting.

Re: [SlimDevices: Plugins] Using plugin to get Internet radio track data from web site
I'm doing something like that - especially as the code started from your DRS plugin. I'll put more tracing in to see what is called but I think what happens is that when 2nd client starts I get a call and I see that there is already a poll timer running for the station so I don't set up a new timer for this client. All subsequent timer expires are only for client 1 so I never push anything new to client 2.

Re: [SlimDevices: Plugins] Using plugin to get Internet radio track data from web site
However, the problem that this leads me to is when there is more than one device playing the same station (but the devices are not Synched) then I discard call-backs for one of the devices (because I know that I already have a timer set for later for the station) ... which means that when my other timer does expire then only one device is updated. I guess I could run around all of the devices to see if any are playing the same station and push the same update to them - but is there a better way? What I usually do is store the data in a cache, independent from the client. And I store a flag somewhere telling me whether a lookup is being processed. If I get a second request while the first is still processing, I'd tell the second one to try again later. Or I send it back without any new data, letting it update when I send the newmetadata notification.

Re: [SlimDevices: Plugins] Using plugin to get Internet radio track data from web site
I tried remote_title and remotetitle (2nd is mentioned in some code elsewhere) but didn't work - at least when data returned via Code: $song->pluginData( wmaMeta => $info ); Slim::Control::Request::notifyFromArray( $client, [ 'newmetadata' ] ); Anyway - not too important. I could put in a Settings option to disable sending of Album info so that the station name appears. One more, and hopefully last, issue ... I have been trying to optimise things to reduce call-backs and fetching from the source web site - so I collect data based on the station (using basically the same "meta" object as in Michael's DRS plugin.

Another question ... when playing a stream via its URL (as opposed to playing it by name in TuneIn or a favourite) the stream URL is shown (on a Touch-like display) just below the title/artist. When playing a station by name then it is the station name that is shown. Try returning a remote_title in your metadata. If there's no album name for a remote stream, but that remote_title, then I think it will be shown. But TBH: I only find that value being used.

Without really knowing why ... this is now working. Next step is to make it a bit more tolerant of faults in the source and to work out why things don't work so well when 2 different unsynched Squeezeboxes are playing the same station (I think in my suppression of actions when getting too many callbacks I have lost updates to one of the devices).

Re: [SlimDevices: Plugins] Using plugin to get Internet radio track data from web site
I couldn't get that to work either. So went back to basics - and found that Slim::Formats::RemoteMetadata->registerProvider - which, when called takes the "info" structure as a return, is working. It is odd though. I get around 6 calls in the same second or so - then the same set of calls about once every 10 minutes. In my case the source ICY metadata never changes so that is not the trigger, If I could get the 10 minutes to be 15-30 seconds then all would be well and I would not need the self-timer to work (which I have currently commented out).

I'm doing the following (in aforementioned DRS plugin) before sending
the newmetadata notification:
$client->playingSong->pluginData( wmaMeta => {

Make this $client->master... if needed (I do this in the beginning).

Re: [SlimDevices: Plugins] Using plugin to get Internet radio track data from web site
I have the periodic polling now working - and am getting the data back
from the radio station web site (annoyingly it is about a minute behind
- and have not checked to see if that is LMS caching, someone else
caching, or remote site being out of sync).
However, my updated metadata is not appearing on player screen.
I have taken code from elsewhere and it may well be relying on something
that I have not set-up correctly.
But ... would you expect that track info to update when this is done?
Code:
$client->master->pluginData( metadata => $info );
Slim::Control::Request::notifyFromArray( $client, [ 'newmetadata' ] );
Slim::Control::Request::notifyFromArray( $client, [ 'playlist', 'newsong',
$info->{title} ] );
where $info has something like this:
$info->{artist} = 'The Beatles';
$info->{title} = 'A Hard Day's Night';
and "client" is what is passed around as first parameter in lots of
calls ... (this bit I am dubious about!)

I can see how to get the data from the broadcaster's web site but can someone give me some pointers for how to get the plugin called periodically? Look into Slim::Formats::RemoteMetadata. Register a data provider which will be called as soon as your station is being called. Then run some polling code (Slim::Utils::Timer) to update the data as long as you're streaming that station. You might need to check yourself whether you're still streaming that station, and stop timers accordingly. -- Michael ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Hello,. I'm looking into writing a plugin to provider track meta data because the ICY metadata is empty. I can see how to get the data from the broadcaster's web site but can someone give me some pointers for how to get the plugin called periodically? I can't do it on stream metadata change because the data within the stream does not change. Ideally should be reconfigurable interval because the broadcaster web info shows when the next track is due ... so I could say "call me back in X seconds". I have looked at the Orange Liveradio plugin and Michael's DRS one but they seem to rely on the metadata in the stream changing.
