v4l2-ccd stacking function? - by: pauledd

hi,
I dont know if indi does it already but I guess it doesnt. In the v4l2ccd tab there is an option for stacking. If I click on it while having the live stream window open It seems to stack nothing. In (open)PHD the v4l video gets stacked by an adjustable integration time. Do I misunderstand the function in ekos or is this only made for cameras that do internal integration?

[edit] and would'nt the stacking of an bad v4l signal help the autoguide process to reduce noise and some seeing?
