Category: None Group: None Status: Open Priority: 5 Private: No Submitted By: Cyrille Henry (nusmuk) Assigned to: Nobody/Anonymous (nobody) 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
