JSON API to get a screenshot and/or current dominant color.

Feature request

What problem does this feature solve?

I am trying to get and download a screen capture of what is processed by hyperHDR. I want this to create a dominant color sensor on Home Assistant.

Another aproach could be get an JSON API to expose the current dominant color value.

What does the proposed API look like?

What i am looking for is an JSON API that return the the current image being processed by HyperHDR (Like the Live "Screenshot" feature of the GUI.)

How should this be implemented in your opinion?

n/a

Are you willing to work on this yourself?

Should learn C/C++.

Hi
How often do you plan to execute it? I'm afraid this is the perfect backdoor to kill HyperHDR/RPi with overload as such a potential command is not guarded and averaging over the whole image (or returning the image as a string/base64 encoded in the JSON result) is very time consuming? Alternatively, the average color of the LEDs for the selected instance?

Hi Awawa, thanks for your fast response.

I want to execute this just on certain media_player state changes (Ex: to playing, to pause and track changed) using the built in home assistant color quantizer.

Also like the idea of get the average color of leds for a specific instance instance. It should works well and it is cheaper for the cpu cause i may create a instance with just a few leds to make the math easier.
