Hi Paulo,
I've also done some work on libwebcam a while ago, but have not yet had
the time to send this to Martin Rubli. Attached are git format-patch
patches against the 0.2.1 branch of svn. Note these are against what
was in that branch when I did this work some months ago, so not sure
if it
p.s.
Some of my commit messages talk about them needing some
kernel changes / fixes. These are all long in place now
(since before the uvcvideo.h header become an official
userspace available kernel header).
Regards,
Hans

Changes since v3, these are mainly corrections after comments from
Hans (thank you!):

This patch adds V4L2_CID_AUTO_N_PRESET_WHITE_BALANCE control which is
an extended version of the V4L2_CID_AUTO_WHITE_BALANCE control,
including white balance presets. The following presets are defined:
- V4L2_WHITE_BALANCE_INCANDESCENT,
- V4L2_WHITE_BALANCE_FLUORESCENT,
-
The camera may in some conditions incorrectly determine the exposure,
and a manual automatic exposure correction may be needed. This patch
adds V4L2_CID_AUTO_EXPOSURE_BIAS control which allows to add some
offset in the automatic exposure control loop, to compensate for
frame under- or
Add ISO sensitivity and ISO auto/manual controls. The sensitivity
values are related to level of amplification of the analog signal
between image sensor and ADC. These controls allow to support sensors
exposing an interface to accept the ISO values directly.

The V4L2_CID_3A_LOCK bitmask control allows applications to pause

It can be used, for example, to lock the 3A adjustments right before
