Starting Leds when Emby is sending video.

[ravenneo 0]

I have a emby server working really fine in a Raspberry pi 4B. I have a wee hat on the raspi with leds and my idea is start the leds when someone is playing some video from the server.    Does anyone have any idea/advice/guide to do that?

 

Many thanks

 

Edit: I am sorry I have just seen that there is a raspberry subforum

Hi, you could do something like this with webhooks.

@chef may have some tips.

Thank you for your reply, I haven't listen before about this webhooks, I am going to do some research     If anyone has another idea I will try it as well !

Do your LED lights have an http command to command them?

Do they have a wifi module?

Hi, the led system is this one: https://github.com/pimoroni/led-shim

It goes attached to the GPIO on the raspi

Cool! When using the shim, how are you turning them on?

I normally go into the pi using ssh from my phone and then run a python script to make LEDs works. It is some kind of "ambient light" (I really like shinny things hahaha)  But it would be great that with just activating emby the LEDs go on

 

I just run an example from pimoroni called "rainbow"

#!/usr/bin/env python

import colorsys
import time

import ledshim

spacing = 360.0 / 16.0
hue = 0

ledshim.set_clear_on_exit()
ledshim.set_brightness(0.8)

while True:
    hue = int(time.time() * 100) % 360
    for x in range(ledshim.NUM_PIXELS):
        offset = x * spacing
        h = ((hue + offset) % 360) / 360.0
        r, g, b = [int(c * 255) for c in colorsys.hsv_to_rgb(h, 1.0, 1.0)]
        ledshim.set_pixel(x, r, g, b)

    ledshim.show()
    time.sleep(0.0001)

 

I am still learning to write this kind of things (my first year into linux-python world)

Okay. I think we need to create a web service on the pi. Something we can contact with either a "GET" or "POST" request which will run the code. 

Then we can use embys built in Webhooks to do this.

I'm not familiar with creating a web service using python. 

Maybe Stack overflow has a post we can learn from.
