Summary: add control to uvc devices on linux

Initial Comment:
most webcam are using uvc driver on linux. this drivers allow control over diferents parametters of the camera (lighting / gamma / etc).
it would be nice to be able to control this parametters from a Gem patch.
by example, to be able to remove auto luminausity is very important for tracking...

Message:
i totally agree.
the problem is mainly to stay consistently across the increasing number of
backends for Gem's video-capture (e.g. how to make sure that all backends
use the same names for features; what about features that don't exist on a
certain platform?)

i'm currently thinking of a way to query the available parameters for the
current device and make this available within the patch), so you could
write a patch that generates the "dialog" to control what's controllable
