From fa59c01eadd849ed2e5b0cf1406347bf632c80ed Mon Sep 17 00:00:00 2001 From: "hans@rhel5-devel.localdomain" Date: Mon, 13 Apr 2009 20:02:34 +0200 Subject: libv4l: add video processing: whitebalance and normalize From: Hans de Goede As the version number shows this work is the basis for a beta release of the 0.6.x series, the big change here is the addition of video processing to libv4l currently this only does whitebalance and normalizing (which turns out to be useless for most cams) but the basic framework for doing video processing, and being able to control it through fake v4l2 controls using for example v4l2ucp is there. The initial version of this code was written by 3 of my computer science students: Elmar Kleijn, Sjoerd Piepenbrink and Radjnies Bhansingh. This initial hg commit is a cleaned up and somewhat bug fixed version of their code.
