 python-v4l2capture is a slim and easy to use Python extension for
 capturing video with video4linux2. It supports libv4l to convert any
-image format to RGB.

 Installation
 ============
 
 v4l2capture requires libv4l by default. You can compile v4l2capture
-without libv4l if you only want it to support video devices supporting
-the YUYV pixel format. You can do so by erasing ', libraries =
-["v4l2"]' in setup.py and erasing '#define USE_LIBV4L' in
-v4l2capture.c.
+without libv4l, but that reduces image format support to YUYV input
+and RGB output only. You can do so by erasing ', libraries = ["v4l2"]'
+in setup.py and erasing '#define USE_LIBV4L' in v4l2capture.c.
 
 python-v4l2capture uses distutils.
 To build: ./setup.py build

 Change log
 ==========
 
+1.4 (2011-03-18) - Added support for YUV420 output.
+
 1.3 (2010-07-21) - Added set of capabilities to the return value of
                    get_info. Updated list_devices.py.
