[Suggestion] Improvements to the display/screen sync about hue-lights HOT 2 OPEN

Hi @DatCaptainHorse ! Thank you for your suggestion. I wanted to improve it, but I wasn't able to find a better and working solution so far. The problem is to get the region's average color in GJS in time. The only way I found was to use the gnome-shell function getColorPixel(), which is at least... fast enough if only a few pixels are used.

I tried several approaches like gstreamer or taking screenshots of the whole desktop and analyzing. Taking screenshots is too slow. Much slower than calling getColorPixel() a few times. I hope someday I will change this feature to use the gstreamer but currently it is not possible. Long story short: this issue: https://gitlab.gnome.org/GNOME/gjs/-/issues/557 is stopping me. I can not connect to the signal from gstreamer successfully.

Do have an idea of how to get the screen color fast enough in gjs? Please share the technical knowledge:-) ...or at least which component would you use? I will happily improve the sync feature with such a hint.

Hi @vchlum , if I could add my thoughts to this and start with a big thank you for this software - I love it. I just bought a Hue Gradient Light Strip for my PC and it's working in Linux, using your software, in Wayland. Huestacean and Huenicorn don't work, so thank you!!

I think the screen colour picker is not the main issue (for me, at least). It seems that when I'm playing a game, or am on my desktop, the colours get sampled OK.

The main issue is that there is no blending of colours as they transition from one to the next. What I mean by this is:

ColourGetsSampled -> NewColourGetsSampled -> InstantChange (it's an instant transition and is quite jarring)

I would suggest a transition.

ColourGetsSampled -> NewColourGetsSampled -> GradualChange

Now I don't know how to code, but this YouTube video for a complete different app probably shows it best:

As mentioned earlier, if this colour-blending could happen faster-slower depending on "Intensity" setting, that would be helpful.

Does this make sense?
