missing "now playing" values on screensaver

[chaseadam]

I am calling the plugin using the very handy tidal: and https://listen.tidal.com protocol handlers like so:

curl 'http://127.0.0.1:9002/jsonrpc.js' -X POST --data-raw '{"id":1,"method":"slim.request","params":["00:04:20:06:XX:XX",["playlist","play","tidal://album:55163258"]]}'

All of the track information is present when inspecting details when browsing with the remote and in in LMS, but the "now playing: " only on the "now playing" screensaver is blank if I have not started the song from the Tidal app in LMS before. If I start the song, then it will always display the screensaver now playing value correctly.

I can replicate this down to individual tracks within an album.

• trigger an album only via similar API call above
• note, every track has empty "now playing" value only on the screensaver
• open tidal app in LMS webUI
• search and find track
• hit play button on track
• trigger same album using the API call
• "now playing" on the screensaver populated correctly for the one track we found and played

I believe this has something to do with how the plugin syncs/stores the values of the tracks. Maybe there is a specific value used by the screensaver which is not populating via the protocol handler pathway?

I noted that current title from status command is empty when playing the tracks with missing values

Using my freshly fixed SB3 with this fantastic plugin. Very impressed with completeness and polish!

[michaelherger]

Are you saying this was a problem with the SB3's Now Playing screensaver only? The web UI would show the track information? Can you share a "screenshot"?

[chaseadam]

Yep only the screensaver while playing (not sure if that is the same as "now playing screensaver"

this is the experience going through tidal://album:55163258

I have previously "played" the first two tracks individually using the process below so they are populated, but track 3 and beyond are not

2024-04-02-10-29-46-629.mp4

Then I go through this process to "populate" the "screensaver now playing" value:

press "play" icon (which replaces the playlist)

retrigger the album play with URI via API:

curl 'http://127.0.0.1:9002/jsonrpc.js' -X POST --data-raw '{"id":1,"method":"slim.request","params":["00:04:20:06:XX:XX",["playlist","play","tidal://album:55163258"]]}'

The value is populated:

2024-04-02-10-36-45-451.mp4

Could be red herring, but I believe this value may be tied to the current_title value I get with status request.
When value is empty vs populated:

➜  curl --silent 'http://127.0.0.1:9002/jsonrpc.js' -X POST --data-raw '{"id":1,"method":"slim.request","params":["00:04:20:06:ac:22",["status","-","-1","tags:uB"]]}' | jq .result.current_title
""
➜  curl --silent 'http://127.0.0.1:9002/jsonrpc.js' -X POST --data-raw '{"id":1,"method":"slim.request","params":["00:04:20:06:ac:22",["status","-","-1","tags:uB"]]}' | jq .result.current_title
"I'm Only Sleeping (Remastered 2009)"

[michaelherger]

Your SB isn't synced with another player, is it?

Please enable debug logging for plugin.tidal, reproduce the issue, then send me a copy of the resulting server.log.zip to https://www.dropbox.com/request/T3RctyzGgNg0oFDubq6a (Settings/Advanced/Logging)

[chaseadam]

not synced

uploaded logs. I ran through the procedure in the last few minutes after 16:50 in the logs:

• play API triggered album to replace playlist
• track next through some tracks to point of "empty" screensaver values (track 5)
• search for track 5 name
• play track 5 individually (replaces playlist) (notably, the screensaver value is populated)
• play API triggered album to replace playlist
• track next through to track 5 and the screensaver value is populated

[michaelherger]

Trying to reproduce this... what screensaver are you using? I'm seeing SaverSwitcher is involved. Could you please go back to just the default Now Playing screensaver. Is the behaviour the same?

From the log I'm not seeing what I hoped I'd see. How technical are you? Would you be able to modify one of the source files to try something out?

[chaseadam]

I am technical, but I do not have much perl experience. I definitely do some guided modifications.

This is the "now playing" value which pops up for a brief period when "screensaver while playing" is active. Note that this triggers when the track changes (either due to track end and next track on playlist or track change via API).

The video is of the "spectrum analyzer" value of "screensaver while playing":

When using the "now playing" value of "screensaver while playing" the value is correct.

Even with the "spectrum analyzer" screensaver active and showing an "empty" value, you can also see in the video a very brief view of the "now playing" screen which appears to be correct. See second 6-10 of the video:

2024-04-02-10-36-45-451.mp4

More red herring research:
Have noted previously that the network payload to the device is different for the "empty" values and I included the network.jsonrpc debug. The "status" response values are different (specifically the "current_title" is empty). Why it is empty appears to be the cache is loading differently if played via an "album" playlist vs direct track play causing the missing "current_title" the status payload.

Here is a reference which only adds the current_title to a Jive request (I see other references to Jive in issues which makes me think it is related, but I am using a SB3...) if certain values are present:
https://github.com/LMS-Community/slimserver/blob/5630727fbeb277f6fa2fa0cf042c9adc2662cecc/Slim/Control/Queries.pm#L4680
A few other references to current_title in that file as well:
https://github.com/LMS-Community/slimserver/blob/5630727fbeb277f6fa2fa0cf042c9adc2662cecc/Slim/Control/Queries.pm#L4697
https://github.com/LMS-Community/slimserver/blob/5630727fbeb277f6fa2fa0cf042c9adc2662cecc/Slim/Control/Queries.pm#L1235

[michaelherger]

Can you please confirm the default Now Playing screen saver would behave the same?

[chaseadam]

When using the "now playing" setting for "screensaver while playing" the value is correct.

[michaelherger]

I'm sorry, this has to wait. This seems to be a rather exotic issue (legacy players only, specific screensaver only, TIDAL only(?), when adding tracks over JSON/RPC only). I'm not even sure whether this is a TIDAL or an LMS issue.

I have to prioritise other work. Please ping me again once the Lyrion transition has settled. Thanks for your understanding!

[chaseadam]

No worries, I understand the priority. Some additional research I did via the logs (this is the first I saw of the logs).

I note that the Slim::Schema::RemoteTrack::setAttributes value for track when playing for the first time via passing album URI to API is different and there is a schema error for tracks which don't show the title:

I think the current_title is used by the screensaver and that value comes from a lookup of the URI in the DB and the "now playing" value comes from the playlist (which Tidal plugin is managing properly always).

The following example log shows after "search for track and play" procedure. Notably this includes a "setTitle" action (presumably triggered from Tidal plugin):
