no.frame = True
7. Run PeppySpectrum

8. Demo video clip

9. help needed
i. currently I'm using the mpc status to start/stop PeppySpectrum, this is ok for Radio / File / UPNP, but not working for BlueTooth / Spotify / Airplay, may I know how to detect BlueTooth / Spotify / Airplay is activating ?
ii. I've tried to use a transparent picture (png format) for the PeppySpectrum's background, but it is still black overlay the original MoOde display items, so now I set Pure Black as the Preferences without Cover backdrop, then the screen looks a bit clean, but I love Cover backdrop and hope the PeppySpectrum's background picture can be really transparency, so that screen will be wonderful, may I know is it possible ? and how ?
Thank you.

Open System config and turn on the Metadata file then use the commands below to see whats active and whether it's playing. The Metadata file gets updated within 3 seconds of any changes in playback state.
Code:
pi@moode:~ $ grep "file" /var/local/www/currentsong.txt | cut -d "=" -f 2
Airplay Active
pi@moode:~ $ grep "outrate" /var/local/www/currentsong.txt | cut -d "=" -f 2
16 bit, 44.1 kHz, Stereo, 1.411 MbpsWhat viewport size does that screen report?
Use the command below to display the viewport size in a popup notification when Menu, Refresh.
Code:
# Display viewport size in popup notification
moodeutl -q "update cfg_system set value='viewport' where param='pkgid_suffix'"
# Turn off the viewport popup
moodeutl -q "update cfg_system set value='' where param='pkgid_suffix'"RE: PeppySpectrum with MoOde - franktw956 - 10-27-2022

Thank you, Tim,
I will try out the grep later.
The viewport size is 1919x549, so I made some changes in moode.css
/* Ultrawide 1920 x 550 panel (viewport 1919x549) */
@media (min-height:549px) and (width:1919px) {
img.coverart {width:78vh;}
.playqueue .pll1 {font-size:2rem;}
.playqueue .pll2 {font-size:1.5rem;margin-left:calc(3em + 1vmin)!important}
#volcontrol, #countdown {height:8vw;width:8vw;padding-bottom:1px;}
}

Ok, the CSS mods explain why the UI isn't so heavily clipped but it's still not ideal. There are prolly a few things that can be done to address that.
There is one more release planned for the end of the year and its mainly focussed on fixing any bugs that are reported and can be reproduced, and a refactoring the CSS and Config screen HTML.
As long as I'm going to be into the CSS I can include your media query for that screen. If you have other changes let me know because it appears that these Ultrawide's are pretty popular.

Maybe I am old-school, but if there that one thing I do hate, it's the "!important" CSS thing.

Cheers, Al.

It's a necessary evil in the current CSS. I'm refactoring it so it will be easier to maintain but I'm not making any attempt to rewrite it.
RE: PeppySpectrum with MoOde - Tim Curtis - 10-27-2022
Playback view on these Ultrawide's could look something like below to avoid clipping and out of proportion controls. The popup volume control is used instead of the knob. Long song titles as are common in Classical would prolly need to be ellipsis limited instead of wrapping otherwise the metadata under the cover clips at the bottom.

Your new layout is better, I just follow it, but I don't know how/where to modify the bottom manu to add popup volume control.
Looking forward for your new layout release, thanks !

16 bit, 44.1 kHz, Stereo, 1.411 MbpsThank you, Tim, the grep command helps.
I got it working, different triggers ~
~ Radio / File / UPNP --> PeppySpectrum
~ Spotify / Airplay --> PeppyMeter
https://youtu.be/eM6GONoWZFc
Not working (but fine with me) ~
~ Bluetooth
Hopefully the albumart can be shown with PeppyMeter in the future.
Thanks again !
RE: PeppySpectrum with MoOde - Tim Curtis - 10-28-2022
For a Bluetooth connection the currentsong file won't be updated until bluez-alsa starts playing something. I suppose I should look at also updating the file initially when Bluetooth connects.
Another way to tell if one of the renderers is active is to query the active flags.
rbactive
aplactive
btactive
slactive
spotactive
inpactive
rxactive
# Dump the session var
sudo moodeutl -d | grep btactive | cut -d "|" -f 2
# Query the table
moodeutl -q "select value from cfg_system where param='btactive'"
