No, sorry, this wasn't my question. By "client" I meant one camera
or
decoder or whatever chip connects to a camera host. I.e., if we
have a
single chip with several inputs, that should logically be handled
with
S_INPUT ioctl, this would further add to the confusion of using
different
inputs on one video device to switch between chips or inputs /
functions
on one chip.
Yes exactly. It was "single chip with several inputs." that I
intended to
tell. but still don't get what the confusion you mean. Sorry ;-()
Cheers,
Wow, so, on those phone a "dual camera" is a single (CMOS)
controller with
two sensors / lenses / filters?... Cool, do you have an example of
such a
camera to look for on the net? Preferably with a datasheet available.
Oops sorry I didn't mean that.
I just meant one single camera interface on Application Processor and
two camera modules (sensor, lens, isp) connected. Sorry I explained
badly.
I considered this as single camera interface with several inputs.
"Confusion" I meant that in this case switching between inputs
sometimes
switches you to another controller and sometimes to another function
within the same controller...
I think we don't need to worry about that if we can query camera
inputs clearly.
Cheers,
Nate
