libv4l 0.5.2 (Default branch)

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 for the application transparent libv4lconvert conversion where necessary. License: GNU Lesser General Public License (LGPL) Changes:
A workaround was introduced for some drivers' (notably pwc's) inconsistency in V4L's s_fmt() versus try_fmt() return values. Other minor improvements were made.

NAME

       devices, devid_cache, snapshot_cache, mdi_scsi_vhci_cache, mdi_ib_cache, devname_cache - device configuration information

SYNOPSIS

       /etc/devices

       /etc/devices/devid_cache

       /etc/devices/snapshot_cache

       /etc/devices/mdi_scsi_vhci_cache

       /etc/devices/mdi_ib_cache

       /etc/devices/devname_cache

DESCRIPTION

       The  directory  /etc/devices  is  a repository of device-related data. Files in this directory are used to preserve this information across
       reboots and are created and updated as necessary by the system.

       There are no administrative actions necessary with respect to files in /etc/devices. Should the contents of a file become corrupted  or	an
       update fail, the file can simply be removed. The system re-creates the file as necessary.
