photoframe.py

[photo-album]

Photoframe displaying (large) photo collection in 'shuffle of' mode always starts with the same photo so the playlist never gets through to the far end.
I'd like to shuffle the start image then from that image onwards be recursive through the folders and files. That would get all the images seen over a few days. Imagine a holiday trip - you'd want to see the pictures it in the time sequence but you dont want to see the same trip each start up.

Apologies if I missed the obvious in my trawl through the documentation.

Hi, something like this cropped up before. I think the random seed relies on using time and that's always the same value when starting at boot (though it seems unlikely that it would be exactly the same). I will try to think of a better way to re-seed it and how you can make it run in order but starting at a random point.

Hi, I've made a few changes on other things and pushed those changes up to the develop branch. However I'm not sure about the shuffle start option. I think it would need to be added as (yet) another command line config variable, as some people might want to start from zero if they were showing images from a specific subdirectory for instance.

As a test you could modify PictureFrame2020.py (around line 330 in the previous version, 360 in the new one)

# images in iFiles list
nexttm = 0.0
iFiles, nFi = get_files(date_from, date_to)
#next_pic_num = 0                     ##<comment out
random.seed()                         ##<add
next_pic_num = random.randint(0, nFi) ##<add
sfg = None # slide for background
sbg = None # slide for foreground

The extra complication is when you change the start and end dates or subfolder using MQTT the selection is refreshed and next_pic_num set to zero. If that's an issue then you would need to change the code in a similar way around line 290 (313 new)

Let me know if this behaves as you would expect.
