Idea: Random pic at start + random fade_time and delay_time

[Brt120]

Hello,

I made a small change in the pictureframe2020.py script to select a random picture from start, I tried setting -n to 0, shuffle to true and -r to zero, but i always seem to have the same picture at start.

Anyway this is what i changed, maybe it's an idea to implement in the config script, set random true or false, i didn't test it yet with subdirectories.

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

I also wrote a small bash script that i can start once pictureframe2020 is loaded, it chooses a random value between 2 given variables, so there's a bit more variation, I'm sending mqtt messages over network, if you want to run the script on the host you can change the ip to localhost. I'm thinking of trying to implement the blend type in this script aswell At first i tried to import random in the pictureframe2020config file but it didn't work, I don't know much about python

This is the script, it needs some more work and finetuning, like adding a few reads but you got the basic idea

!/usr/bin/env bash

a=30 b=60 c=1 d=15 sleep 45 for i in {1..10000} do time_delay=$((a+RANDOM%(b-a))) fade_time=$((c+RANDOM%(d-c))) sleep_time=$(((fade_time/2)+time_delay)) mosquitto_pub -h localhost -m "$time_delay" -t frame/time_delay mosquitto_pub -h localhost -m "$fade_time" -t frame/fade_time sleep $sleep_time done exit

Kind regards Brt

I have made some other changes that might be interesting Added a next, and random-next, to use with mqtt

elif message.topic == "frame/back": next_pic_num -= 2 if next_pic_num < -1: next_pic_num = -1 nexttm = time.time() - 86400.0 elif message.topic == "frame/next": next_pic_num = pic_num + 1 nexttm = time.time() - 86400.0 elif message.topic == "frame/random": next_pic_num = random.randint(0, len(iFiles)) nexttm = time.time() - 86400.0 elif message.topic == "frame/subdirectory": subdirectory = msg reselect = True

and

client.subscribe("frame/quit", qos=0) client.subscribe("frame/paused", qos=0) client.subscribe("frame/back", qos=0) client.subscribe("frame/next", qos=0) client.subscribe("frame/random", qos=0) client.subscribe("frame/subdirectory", qos=0)

Kind regards Bert

Bert, thanks for these. It does seem very odd that the same picture appears first. Are the subsequent pictures also in the same order? Can you tell if the shuffle hasn't happened at all (in which case the images will appear in name order) or that it does happen but the random.seed() is always the same.

The import of random should reseed it using the system clock but if python and the module is loaded before the time is reset (over the network presumably) and the time to load everything up to here happens to be exactly the same each start then I suppose it could generate the same random sequence. If this is the case then one minor change (one more or less file) will generate a completely different sequence. However if this is the case it seems odd that your random.randint() doesn't generate the same number. Very odd. What happens if you put a random.seed() before the get_files() call?

I'll do some more testing in the weekend probably, I keep you posted, it's kinda busy at work for the moment.
