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) 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 for the
|
||
|
|
application transparent libv4lconvert conversion where necessary.
