ah, an "input" method is indeed defined in pix_videoDarwin.cpp, but it is 
not mentioned in pix_video-help.pd (of gem 92), and I have no hint that 
something is to be done.

This behaviour of "device" is also contrary to [pix_video]'s 
construction-time behaviour of "pick the first video stream we can find".

I'm all in favour of a more manual camera control (so that the user 
chooses whether to open a camera at all), I'm just pointing out that 
"device"/"input" doesn't seem to be very consistent with [pix_video]'s 
defaults.

BTW, which devices have several inputs on them, in a way that counts as 
"input" here (and not multiple devices) ? I'm curious.
