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.

2009-03-11libv4l: add support for converting to YV12 planarhans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> Add support for converting to YV12 planar (next to the already supported YU12 / I420) and implement RGB/BGR24 -> YU/YV12 conversion Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2009-03-11libv4l: add support for downscalinghans@rhel5-devel.localdomain
From: Lukáš Karas <lukas.karas@centrum.cz> Add support for downscaling to make apps which want low resolutions (skype, spcaview) happy when used with cams which can only do high resolutions.

2009-03-11libv4l: Add software cropping from CIF to VGA modes (fix skype)hans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> * Add support for software cropping from 352x288 -> 320x240 / 176x144 -> 160x120, so that apps which will only work with vga resolutions like 320x240 (Skype!) will work with cams/drivers which do not support cropping CIF resolutions to VGA resolutions in hardware. 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>
