MMM-GooglePhotos

krouton

Hi Sean,

I keep getting the “[GPHOTO] Scan finished : 0/There is no scanned photo currently.” error however there are 3000 photos in the folder. Sometimes it will successfully scan and display the photos fine but more and more recently it fails.

{
		module: "MMM-GooglePhotos",
		position: "fullscreen_below",
		disabled: false,
	config: {
		albumId: "xxxxx", // your album id from result of `auth_and_test.js`
		refreshInterval: 1000*60*5,  
		scanInterval: 1000*60*10, // too many scans might cause API quota limit also.
			//note(2018-07-29). It is some weird. API documents said temporal image url would live for 1 hour, but it might be broken shorter. So, per 10 min scanning could prevent dead url.

		sort: "random", //'time', 'reverse', 'random'
		showWidth: "1380px", // how large the photo will be shown as. (e.g;'100%' for fullscreen)
		showHeight: "1060px",
		originalWidthPx: 1380, // original size of loaded image. (related with image quality)
		originalHeightPx: 1060, // Bigger size gives you better quality, but can give you network burden.
		mode: "contain", // "cover" or "contain" (https://www.w3schools.com/cssref/css3_pr_background-size.asp)
  }
},

Inspector shows it loads the module but not an actual photo.

Any help would be greatly appreciated.

Move to some smaller folder than try again. 3000 would be so many photos, and ther could be more in your subdirectories.

By the way, sorry for out of topic, but…
RCREPO seems too many times working. Scanning should be executed at start of MM once. Why did the log say so many times?
Would you try again after removing MMM-Remote-Control-Repository from config.js??

@Sean , thanks a ton for this great module. My wife would have never been ok with a Smart display in our family room without having family pictures on it.
I have MMM-Google photos on full screen mode (monitor is in portrait mode). It works perfectly as expected - although the pictures come up as pixelated or not as sharp in lower resolution. All photos in my configured album are uploaded in full resolution. Is there any way to display it in high(est/er) resolution?

My configuration is as below:-

		{
		  module: "MMM-GooglePhotos",
		  position: "fullscreen_below",
		  config: {
		    albumId: "XXXXX", // your album id from result of `auth_and_test.js`
		    refreshInterval: 1000*60,  
		    scanInterval: 1000*60*10, // too many scans might cause API quota limit also.
		    //note(2018-07-29). It is some weird. API documents said temporal image url would live for 1 hour, but it might be broken shorter. So, per 10 min scanning could prevent dead url.
		
		    sort: "random", //'time', 'reverse', 'random'
		    showWidth: "100%", // how large the photo will be shown as. (e.g;'100%' for fullscreen)
		    showHeight: "100%",
		    originalWidthPx: 1920, // original size of loaded image. (related with image quality)
		    originalHeightPx: 1080, // Bigger size gives you better quality, but can give you network burden.
		    mode: "hybrid", // "cover" or "contain" (https://www.w3schools.com/cssref/css3_pr_background-size.asp)
		    //ADDED. "hybrid" : if you set as "hybrid" it will change "cover" and "contain" automatically by aspect ratio.
		  }
		},

@yupwho - Hmm. If you uploaded at full resolution, they are probably higher than 1920x1080. Specifying those parameters may be causing some weird resizing artifacts.

As an experiment, trying taking out the orginalWidthPix and originalHeightPx parameters and see what you get.

@bhepler Thanks! Removing it seemed to worsen the quality. I think I am going to experiment with different values here - https://en.wikipedia.org/wiki/Display_resolution#Common_display_resolutions.
I have tried the 2560*1440 and it looks little bit better.

Still looking if there is a more definite solution.

Thanks!

Set originalWidthPx and originalHeightPx to higher value.

But dithering would be unescapable destiny. Because Max Screen Size of supported in RPI would be 1920*1080 and your pictures are larger than, so Dithering should be happened.

Usually Dithering - Scaling up/down, by index of 2 (e.g: X2, X4, X1/2, X1/4) would be better than other values.
So, dithering to 800X480 from 1600x960 could be better from 2000X1200.

And I think the best values would be the same size to display.
Because, if dithering would be happened, it would be done twice - once when your Google Photo send picture to RPI by OriginalWidth/Height and once again when my module showing it by showWidth/Height.
So, The best case would be all the same sizes - your picture original, OriginalWidth/Height, showWidth/Height are same. In other case, somewhat quality down is unavoidable. My module has no correction/manipulation method because this is not photoshop. sorry.

@sean Thanks for the details - agreed! I am going to experiment with various config values and picture types. Awesome work with the module - works out of the box as expected!

I have been messing around with this module for a couple of days now and am really impressed with the way it works and the aspect ratio switching. I have a question though about the way the module displays pictures with borders. Would there be a way to either: display the image at the top of the frame and leave all of the black space below the image, or display two landscape images on top of each other instead of bordering the images?

Thanks for any help with this.

Sorry for my poor English, I have a trouble to catch your points. If you can show me the example (simple image??) It will be a help.
