libv4l is a collection of libraries that adds a
thin abstraction layer on top of video4linux2
(V4L2) devices. The purpose of this layer is to
make it easy for application writers to support a
wide variety of devices without having to write
separate code for different devices in the same
class. It consists of 3 different libraries.
libv4lconvert offers functions to convert from any
(known) pixel format to V4l2_PIX_FMT_BGR24 or
V4l2_PIX_FMT_YUV420. libv4l1 offers the
(deprecated) v4l1 API on top of v4l2 devices,
independent of the drivers for those devices
supporting v4l1 compatibility (which many v4l2
drivers do not). libv4l2 offers the v4l2 API on
top of v4l2 devices, while adding support for the
application transparent libv4lconvert conversion
where necessary.

Changes:
Support for the UYVY colorspace was added. A duplicate conversion function was removed. The pkg-config file was fixed. USB IDs are now used instead of the USB product strings, fixing potential issues.
