2009-05-17libv4l: fix v4lconvert_uyvy_to_yuv420()hans@rhel5-devel.localdomain

2009-05-16libv4l: add ability to determine flags based on DMI infohans@localhost.localdomain
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. It also adds the webcam in the Asus N50Vn as the first upside down cam identified this way. Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>

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. The initial version of this code was written by 3 of my computer science students: Elmar Kleijn, Sjoerd Piepenbrink and Radjnies Bhansingh.

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.

From: Hans de Goede <hdegoede@redhat.com> Avoid the use of try_fmt as much as possible on UVC cams, instead use the results of the enum_framesizes ioctl. This is because: 1) try_fmt actually causes IO with UVC cams making apps which do lot of querying of device capabilities slow (cheese) 2) some buggy cams don't like getting lots of UVC video probes and crash when they do Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>

This makes all 2.6.27 gspca supported cams, except for the pac7302 which only does 640x480 (and skype wants 320x240), work with skype * The v4lconvert_convert function was becoming a bit of a mess, so split the functionailiy into seperate v4lconvert_convert_pixfmt, v4lconvert_rotate and v4lconvert_crop functions, and make v4lconvert_convert a frontend to these Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>
