Which pinephone ? The pro or the original one ?

(Difference being that the Pro is a RK3399, which features an ISP
which libcamera supports natively, while the original one has no ISP)

I suggest you to use our cli test application in src/cam/
We also have a GUI one in src/qcam, but it's Qt based, and I'm not
sure if you have Qt there...

However cam recently gained support for an SDL output which might be
easier to exercize.

test/ contains the library unit tests, not something that is interesting
for users

Yes, cam does that.

Thanks for testing and keep us posted ;)
