[SOFT] dynquee: dynamic marquee for Recalbox

[daniel6984]

@POPPADUM Bonjour,

J'ai une question pour un ami, il a un rpi4 avec un RGB DUAL qui ce branche via les GPIO, il est brancher en péritel sur une petite télévision crt 14 pouces d'une résolution de 320x240 fréquence 15khz, il a voulu tester les marquees sur un écran lcd brancher en hdmi , mais les images apparaisse que sur la télévision crt, avez une astuce pour faire apparaitre les images marquee sur le lcd ?
Je vous remercie

Pour le raspberry pi 4, les deux écrans HDMI partagent le framebuffer, mais il semble qu'avec un RGB Dual le framebuffer ne s'affiche que sur le CRT.

Pour Recalbox PC dynquee utilise mpv --screen=2 pour afficher les images sur l'écran 2. Pourrait-il tester si cela fonctionne avec:

mpv --screen=2 --loop <image.png>

@poppadum Bonjour,
merci beaucoup de nous avoir repondu.
Nous voulons tester la ligne que tu nous a donnée, nous somme que sur rpi4 , dans le .ini , ou faut-il insérer la ligne mpv --screen=2 --loop <image.png> ?
Merci encor pour ton aide

[poppadum]

@daniel6984 Pour tester c'est plus facile d'accéder au cli et d'entrer

mpv --screen=2 --loop /recalbox/share/dynquee/media/startup/startup.01.png

Ou modifiez dynquee.ini lignes 169-170:

viewer = /usr/bin/mpv
viewer_opts = --screen=2 --loop {file}

@poppadum Bonjour
Merci beaucoup pour l'aide ,
ont a essayer par le .ini, ont a bien l'image du startup sur l'écran lcd mais plus d'image sur le CRT et aucun mouvement d'image n'apparait quand ont va de droite a gauche, l'image startup reste fixe.

J'ai oublié qu'il faut aussi modifier (dynquee.ini ligne 174):

terminate_viewer = yes

mais plus d'image sur le CRT

Tu vois rien sur le CRT, ni les images de marquee ni les jeux?

[daniel6984]

@poppadum Bonjour,
Avec la ligne terminate_viewer = yes, il y a bien l'image des marquees que sur le crt pendant le chargement du jeux, mais rien sur l'écran lcd

Hi, I also had the same problem.
It seems that the ultra wide screen is not really 1920 x 360. I solved it by setting it to 1920 x 1080 by editing lines 14, 15 and 170

13  # marquee resolution: change to suit your marquee screen
14  marquee_width = 1920
15  marquee_height = 1080

168   # path to image viewer executable & options
169   viewer = /usr/bin/fbv2
170   viewer_opts = --noinfo --enlarge --ignore-aspect {file}

Let me know if you solve at least partially

Hmm

Et aussi rien sur l'écran lcd avec

viewer = /usr/bin/mpv
viewer_opts = --screen=1 --loop {file}

?

@poppadum Awesome!!!

Where did you buy your LCD marquee? What dimensions?

[poppadum]

@toniosj It's from CaisonLCD in China - model number DV190FBM.

It's a 19.1" panel with resolution 1920x360
Dimensions are 116mm(L) x 87.3mm(W) x 19mm(H)

There are now quite a few different panels available on Amazon too.

Can anyone help? I have installed via the easy option above and it seems everything is there however I am using a Pi4 with RBGpi on one setup and a Pi5 with RGBDual both running on Scart CRT TVs perfectly.
However no matter what I try I can not get any of my 3 marquee displays working.
The marquee picture does quickly flash up on the CRT then goes off as any game loads.
The 2nd display just reports no signal as does any display regardless if its a letterbox widescreen or full size 1080p one
It would make my year if this could be solved.
Thanks in advance Coly

Hi @Colywobbles
I don't have either an RBGpi or RGBDual to test with but it's likely those are the reason it's not working as intended.

On a Pi 4/5 with 2 displays connected to the HDMI ports, both screens share a single framebuffer device. dynquee uses the fbv2 command to display an image on the framebuffer. This means marquee images are shown on both screens briefly when an emulator launches or exits. While a game emulator is running it writes directly to the first display so you see the game running on display 1 and the marquee image on display 2.

My guess is that the RGB devices are interfering somehow. To debug you could connect to your Recalbox via ssh and stop EmulationStation and dynquee by pasting in these commands:

es stop
/etc/init.d/S32dynquee stop

then test if you can get an image to display with
fbv2 /recalbox/share/dynquee/media/startup/startup.01.png

It could also be useful to run
ls -l /dev/fb*
and let me know what the result is.

@poppadum Does it posible to show an image/video in the marquee while Recalbox is showing the intro video on first screen?

[poppadum]

@toniosj On Raspberry Pi, no because the splash video is using the same framebuffer as the marquee.

On PC dynquee is started from the xinitrc when X (the graphical user interface) starts and I can't think of any way that it could start earlier.

The one way it could work is if you run dynquee on a different device to recalbox (e.g. a Pi Zero 2W), but even then you couldn't be certain that dynquee would start up faster than recalbox.

[toniosj]

I've detected a problem in PC.

I've configured the recalbox monitor and marquee monitor. But sometimes, when I reboot Recalbox, the screens are swapped and I have to restart again.

I have to restart several times until everything is displayed on the corresponding screen.

Recalbox PC 9.1

@toniosj

Update: The problem occurs when rebooting from ES in the Recalbox menu.

If I turn it off completely, and turn it back on, everything appears in its place.

[toniosj]

@toniosj
Update 2:

It also happens sometimes on the first start.

It starts with changed monitors on some occasions.

[toniosj]

@toniosj Fixed using two graphic cards.

Ah, interesting. It's the xrandr command in /etc/X11/xinit/xinitrc that is supposed to set the screen layout. But the device names that it sees can be quite generic e.g. HDMI-A-0 and HDMI-A-1, and with two outputs of the same type on the same video card, the kernel can be a bit random when deciding which output gets which number.

There's an idea in this stackoverflow answer about using the EDID data to work out which monitor is which and a script called monitor-switch that looks potentially useful.
