 Introduction
 ============
 
-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 or YUV420.
+libvideolive is a slim and easy to use Python extension for
+capturing and streaming video.

-Installation
-============
+Installation on Linux
+=====================
+
+libvideolive on linux requires libv4l by default. You can do so by erasing ', libraries = ["v4l2"]'
+in setup.py and erasing '#define USE_LIBV4L' in v4l2capture.cpp.
+
+libvideolive uses distutils to compile. For Linux:
+
+./setup.py build
+sudo ./setup.py install
+
+Installation on Windows
+=====================
 
-v4l2capture requires libv4l by default. You can compile v4l2capture
-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.
+Modify setup.py to specify locations of libjpeg and pthread external libraries.
 
-python-v4l2capture uses distutils.
-To build: ./setup.py build
-To build and install: ./setup.py install
+With Visual Studio 2010:
+
+SET VS90COMNTOOLS=%VS100COMNTOOLS%
+python setup.py build -c msvc
+python setup.py install
+
+Remember to put the libjpeg and pthread dlls somewhere appropriate.
