MMM-BackgroundSlideshow

@CyruS1337 by default, the raspberry pi OS uses physical memory… if it runs out, it will try to swap out things not being used to make room for current work. but… the swap space is very small, only 100 meg…
so the swap out fails, and the current process is killed

[CyruS1337]

Ok, thanks for the explanation :) I can understand that reasonably. You are a genius

[sdetweil]

@CyruS1337 no… it happened to me!

[CyruS1337]

Now I thought it was solved, but after about 1 hour the screen was black again. I had to stop the MagicMirror with pm2 stop 0 and then restart it with pm2 start 0.

I also changed the size from 100 to 1024.

What else can it be?

sudo dphys-swapfile swapoff
sudo nano /etc/dphys-swapfile / (changed size 1024)
sudo dphys-swapfile swapon

@CyruS1337 and rebooted after changing swap file

This morning, the mirror was dark again.

This is the memory output

pi@raspberrypi_1:~ $ free -m
              total        used        free      shared  buff/cache   available
Mem:            925         220         391           1         313         653
Swap:          1023         118         905

Edit: The mirror was stopped and started and after 15min he was dark again …

I seem to have found the mistake. I have selected one to quality of photos for playing the photos (4mb per photo). The fact that I have chosen a lower quality of the photos, the problem is gone.

[sdetweil]

@CyruS1337 interesting, i use MMM-ImagesPhotos, and have lots of images over 4meg, most in the 11-13 meg range

[CyruS1337]

Yes, that’s really interesting. But since I let the pictures play with max 1-2 MB, the mirror was never black anymore. Although I did the elevation of SWAP.

Hello,

I’m new to magic mirror. Since two weeks I try to get MMM-ImagesPhotos or MMM-BackgroundSlideshow to work with the photos of my camera (all pictures are JPEG with 5 to 10 meg).

Like @CyruS1337 the whole mirror goes black, if I use my photos but works if I use the example-pictures.

@sdetweil :
How did you get this to work with your pictures?
Could you post your config (including tweeks you did) and tell us which pi you are using?

I was so desperate that I looked for alternatives. I found pi3d but couldn’t integrate it into magic mirror.

I would really appreciate your help.

Best regards

MMM-ImagesPhotos

usually black screen means some missing library…
if u npm start from the terminal window you will see runtime messages
also from the developers window , ctrl-shift-i on the mirror keyboard, select the console tab, and scroll up.

you can try my MMM-ImagesPhotos
https://github.com/sdetweil/MMM-ImagesPhotos

my config

		{
			module: "MMM-ImagesPhotos",
			disabled: false,
			position: "fullscreen",  // < --- this is the div location NOT screen covered with image
			config: {
				opacity: 0.9, 
				animationSpeed: 0,
				updateInterval: 30000,  // how often to change pic
				backgroundColor: "#808080", // color around pic (if u want something other than black)
			},
		},

I have run this on pi0 thru pi4, mac, and two non-pi SBCs, odroid Xu4, and nano jetson.
where did u put your pictures? the module is looking in the folder
~/MagicMirror/modules/MMm_ImagesPhotos/uploads

I linked that to a mounted server volume

now, my tweaks were to display the images without distortion… same aspect ratio as taken.
I did NOT want the screen completely filled… (image stretched or clipped)

to use mine, just rename the old MMM-ImagesPhotos folder out of the way, and then git clone my version of the module.

@sdetweil Hi, is it possible to cover the whole screen with mmm images photos?

[sdetweil]

@Stoffbeuteluwe not with my code, no

the original code does fill the screen if u set the max height and width to the screen size

img.style.maxWidth = this.config.maxWidth;
img.style.maxHeight = this.config.maxHeight;

[Stoffbeuteluwe]

@sdetweil Thank you Sam 😀🙏

[Stoffbeuteluwe]

@sdetweil hi Sam can you help me again I have tried a lot but no luck…my screensize is
width: 1080
high: 1920
I don’t know how to set it the right way

Thanks 🙏

[sdetweil]
