2009-05-26libv4l: fix a crash when doing processing on non rgb / bayer datahans@rhel5-devel.localdomain
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>
2009-05-22libv4l: add support for adding black borders (reverse cropping)hans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> Add the capability to provide 320x240 to apps if the cam can only do 320x232 (some zc3xx cams) by adding black borders. 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.

2009-05-21libv4l: Do not set format for control applicationshans@localhost.localdomain
From: Hans de Goede <hdegoede@redhat.com> When we must do conversion (as we want todo flipping / processing) and the cam does not default to a supported dest format, we set the emulated format to rgb24, wait with doing this till the app actually does something format related, otherwise control applications like v4l2ucp used to become the stream owner locking out other apps.

As part of this the normalize filter has been removed as it wasn't functioning satisfactory anyways Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2009-05-20libv4l: add fake controls controlling the software h- and v-flippinghans@rhel5-devel.localdomain
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.

2009-03-11libv4l: add sn9c20x-i420 decoderhans@rhel5-devel.localdomain
From: Vasily Khoruzhick <anarsoul@gmail.com> Recent sn9c20x driver written by microdia project (http://groups.goolge.com/group/microdia) introduce new output format - sn9c20x-i420. This format is actually scrambled yuv420, so it's very easy and fast to convert it to yuv420. This patch adds sn9c20x-i420 decoder to the libv4l-0.5.7 This decoder is much faster than jpeg one (sn9c20x supports JPEG too): sn9c20x-i420 decoder eats only 10% of 1GHz CPU at 640x480x25fps vs 40% of 1GHz CPU in jpeg at same frame size/rate. This format should be preffered for sn9c20x, because sn9c20x driver supports SBGGR8 too, so it should go before SBGGR8 in supported_src_pixfmts.
