[SOFT] dynquee: dynamic marquee for Recalbox

poppadum · 7 Mar 2023, 08:18

I'm building a bartop arcade machine based on Recalbox and I wanted to have a dynamic marquee which can change depending on which game system is selected and which game is being played.

As my Pi4 has dual HDMI outputs I wanted to drive the marquee from the second HDMI output.

dynquee (say "dinky") is the program I wrote to do that. It's a bit over-engineered for what it does, but it seems to be stable now so I've decided to release it in case others find it useful (it has been asked for a few times before; see e.g. 1 2 3 4).

For more info see the project page on github.

All comments / questions / criticism welcome.

Amazing!! Thanks for your work!!

Two questions:

Where did you buy that LCD?
Does it work on Recalbox PC?

@toniosj

3rd question

Does it work in Pi4 if I am using RGBDUAL ?

@poppadum nice project ! Thanks for sharing

I ordered it from Caison LCD in China - the model is DV190FBM; was not cheap though

If you can put up with a TN panel there are some less expensive options around e.g. here or here.

Does it work on Recalbox PC?

I've only tested it on Raspberry Pi so far, but I think it can be made to work. If you've already got Recalbox running on PC, I'd be interested in the output of the command ls -al /dev/fb*

Does it work in Pi4 if I am using RGBDUAL ?

Again, not tested but I don't see why not. Let's give it a try.

@poppadum

ls -al /dev/fb*

ls: /dev/fb*: No such file or directory

Hmm, so no framebuffer device at all

For testing I've installed Recalbox PC on an old Atom-based nettop. It has HDMI & VGA outputs and I connected 2x HD monitors. After Recalbox boots (I do get /dev/fb0) I ran xrandr:

 Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
HDMI-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 16mm x 9mm
   1920x1080i    60.00*+  50.00    59.94  
...
VGA-1 connected (normal left inverted right x axis y axis)
   1920x1080     60.00 +
...

OK, try placing the second monitor to the right of the primary:
xrandr --output VGA-1 --pos 1921x0
and run xrandr again:

 Screen 0: minimum 320 x 200, current 3841 x 1080, maximum 8192 x 8192
HDMI-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 16mm x 9mm
   1920x1080i    60.00*+  50.00    59.94  
...
VGA-1 connected 1920x1080+1921+0 (normal left inverted right x axis y axis) 477mm x 268mm
   1920x1080     60.00*+
...

Better: now we should be able to get images/video on the second screen:

 mpv --vo=gpu --geometry=+1920:+0 -loop media/system/zxspectrum.logo.png
mpv --vo=gpu --hwdec=vaapi --geometry=+1920:+0 -loop media/mame/chasehq.mp4

Yes, it works Or at least, it's a promising start...

I have managed to get it working on Recalbox PC

Because EmulationStation runs under X with Openbox it needs a few tweaks. Please see the first draft of the instructions here.

@poppadum Hi! Thanks for your work!

I've followed your guide, I think that it's all OK, Screen is ON, but it doesn't show logos.

Testing cd /recalbox/share/dynquee
mpv --screen=2 --alpha=blend --loop media/system/zxspectrum.logo.png

I see logo on 2nd screen.

What would I need to do?

If you run that mpv command manually and it shows an image on your marquee screen, that probably means your screen layout is correct.

If nothing shows on the marquee screen after a reboot, check the following:

Is dynquee running?
Try ps -ef | grep dynq: if it's running, you should see python3 dynquee.py listed. If not, check your /etc/X11/xinit/xinitrc & startup_pc.sh.
Check the log file /recalbox/share/dynquee/logs/dynquee.debug.log
Is dynquee trying to run the correct mpv command? You should see DEBUG _runCmd():423 cmd=['/usr/bin/mpv', '--screen=2', '--alpha=blend', '--loop', '/recalbox/share/dynquee/media/startup/startup01.png']

If that doesn't help, could you let me see a copy of these files (put them on pastebin and send me a link, or post them in a forum chat):

dynquee.ini
startup_pc.sh
logs/dynquee.debug.log
/etc/X11/xinit/xinitrc
/etc/openbox/rc.xml

toniosj · 12 Mar 2023, 21:42

@poppadum I've sent you the info via chat.

toniosj · 15 Mar 2023, 14:20

@toniosj It works fine on Recalbox PC!!!

Good job!!

poppadum · 16 Mar 2023, 16:32

@toniosj Many thanks for all your help testing and troubleshooting.

I will update the docs & install script and then do a new release.

poppadum · 16 Mar 2023, 21:30

Version 0.9.6 released featuring much improved support for Recalbox on PC

poppadum · 18 Mar 2023, 14:33

Version 0.9.7 released: adds support for showing images/videos when the Recalbox screensaver is active.

@poppadum Merci pour ce projet. Je relance le sujet car les marquee dynamiques sont une belle idée je trouve et j'ai essayé de trouver des prix moins élevès pour ce marquee.

Déja ici on peut trouver la documementation du lcd / marquee que tu utilises, qui semble idéale pour rentre dans les bornes d'arcade à largeur < 55cm.
https://www.twscreen.com/index.php/lcdpanel/15419/boe/dv190fbm-nb0/19/1920x360

J'ai contacté le fabriquant qui m'a donné un lien Aliexpress pour le maquee pour une prix de 155€ (avec frais de port mais avec ou sans TVA selon la chance et le moyen d'expédition) :
https://fr.aliexpress.com/item/1005005031941676.html?spm=a2g0o.cart.0.0.7a76378dnWxmCd&mp=1&gatewayAdapt=glo2fra
Pour les pros, on peut aussi l'acheter sur alibaba pour encore moins cher mais il faut un numéro de TVA, pour 132€ (avec frais de port mais sans TVA) :
https://www.alibaba.com/product-detail/Supplier-19-1-inch-1920x360-BOE_1600481217818.html

J'ai bien vu ton lien
Mais ça c'est sans la carte vidéo controller. Quelle est celle utilisée pour ta DV190FBM-NB0 ?
https://www.amazon.co.uk/stores/VSDISPLAY/page/316421E3-1519-48A5-9A33-C819BF6613E1
Car on peut en trouver sur aliexpress pour 20€ par exemple ici mais je ne suis pas sûr qu'elle va fonctionner :
https://fr.aliexpress.com/item/4001255790742.html
Est-ce qu'une carte LVDS (2 ch, 8-bit) , 30 pins Connector suffirait ? As tu une idée où en trouver ?

Nelfe · 20 Sept 2023, 16:32

Ma solution c'est sans la carte vidéo controller pour le moment donc j'en cherche une. Quelle est celle que tu utilises pour ta DV190FBM-NB0 ? As tu un numéro de modèle ?

Est-ce qu'une carte LVDS (2 ch, 8-bit) , 30 pins Connector suffirait ? As tu une idée où en trouver ?

J'ai trouvé un revendeur qui les vend beaucoup trop cher sur aliexepress :
https://fr.aliexpress.com/item/1005001854510280.html
https://fr.aliexpress.com/item/1005003604952304.html
Avec une carte intégré en VGA/DVI/HDMI selon mais j'aimerai surtout trouvé cette carte ailleurs ^^

Nelfe · 20 Sept 2023, 16:46

Ok j'ai trouvé la carte controller ici :
https://fr.aliexpress.com/item/1005003922879496.html
Ce qui revient à 155+47 donc moins de 200€... c'est plutot pas mal pour cette qualité d'affichage pour le marquee ^^
Wait and see...

La carte vidéo controller que j'ai reçu manque un numéro de modèle Il y a aussi une carte inverseur universel rétro-éclairage avec le numéro XQY10L17 v9.3

j'ai trouvé la carte controller ici :
