Description-en: Collection of video4linux support libraries (development files)
libv4l is a collection of libraries which adds a thin abstraction layer on
top of video4linux2 devices. The purpose of this (thin) 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. libv4l
consists of 3 different libraries: libv4lconvert, libv4l1 and libv4l2.
.
libv4lconvert offers functions to convert from any (known) pixelformat
to BGR24, RGB24, YUV420 and YVU420.
.
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 for the
application transparent libv4lconvert conversion where necessary.
.
This package contains the development files.
