From: Hans de Goede <hdegoede@redhat.com> We were calling processing on the rotate90_src, but when doing single conversion and not doing rotate90 that was not pointing the buffer we should do the processing on (the converted data), but instead it was pointing to the original src buffer.

2009-05-25libv4l: add software autogain / exposurehans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> Add software autogain / exposure, for camera's which have gain and exposure controls but do not contain the ability to calculate the average lumination in hardware (which is needed to do this in the kernel). This patch enables this for the spca561 rev12a, but it should be usefull for other cameras too. Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>

And more in general the capability to make certain standard resolutions available by adding black borders to slightly smaller resolutions, in case we encounter more cams which have a hardware limitation which makes them do a resolution slightly smaller then the standard ones.

From: Hans de Goede <hdegoede@redhat.com> When we need to go through the fake mmap buffer anyways, we can add fake controls at no cost. So in the case of webcams which only support non standard pixformats, export fake flipping controls, as this can be done at no (performace) cost (until the user activates them).

From: Hans de Goede <hdegoede@redhat.com> It is possible for the same laptop webcam module (so same usb id) to be mounted upside down in some models and the right way up in other laptop models. This patch adds the ability to only apply flags to a webcam based on the combination of usb id and dmi info to identify the laptop model.

From: Adam Baker <linux@baker-net.org.uk> The "fake" controls added by libv4l to provide whitebalance on some cameras do not respect the V4L2_CTRL_FLAG_NEXT_CTRL and hence don't appear on control programs that try to use that flag if there are any driver controls that do support the flag.

2009-04-13libv4l: add video processing: whitebalance and normalizehans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> As the version number shows this work is the basis for a beta release of the 0.6.x series, the big change here is the addition of video processing to libv4l currently this only does whitebalance and normalizing (which turns out to be useless for most cams) but the basic framework for doing video processing, and being able to control it through fake v4l2 controls using for example v4l2ucp is there.
