Descripción del Proyecto

v4l-utils is a collection of various video4linux (V4L) and DVB utilities. libv4l is an accompanying 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.

This development release combines utilities from the v4l-dvb mercurial kernel as v4l-utils with the previous libv4l into a common distribution. v4l-keytable has been renamed to ir-keytable, and now better supports IR. libv4l adds several laptop models to the list of upside-down devices. Pixart JPEG markers removal was fixed. The whitebalance and gamma defaults of various sonixj and sonixb based cams were improved. Gamma correction is now enabled by default on pac7302 based cams. Convert errors in the first few frames of a stream are now ignored.
