Document libv4l at V4L2 API specs
From: Mauro Carvalho Chehab <mchehab@redhat.com>
Since applications aren't prepared to handle all V4L2 available formats,
an effort is done to have a library capable of understanding especially
the proprietary formats.
This patch documents this library, and adds v4l2grab.c as an example on
how to use it.
Parts of the text are based at the libv4l README file (c) by Hans de
Goede.
Thanks to Hans de Goede <hdegoede@redhat.com> for his good work with
libv4l.
Priority: normal
