[BUG] .setDaemon deprecated

[mgineer85]

Hey,

since python 3.10 the use of .setDaemon is deprecated in favor of the property when initiating the object (..., daemon=True, ...)

https://docs.python.org/3/library/threading.html#threading.Thread.setDaemon

It's used 4 times in picamera2, and I get warnings about this in my github actions.

Maybe you want to replace it?

Thx!

Thanks for the info. I'll try and get round to that.
