ucanvcam is (C) 2007, 2008, 2011 Paul Fitzpatrick (paulfitz@alum.mit.edu)
It is free software, under the GPLv2, see GPL.TXT

Certain effects from the EffecTV project are included, under the GPL.

== On Windows ==

On WINDOWS only, ucanvcam contains a plugin called "ucanvcamx" which
has minimal dependencies (DirectX), and implements a virtual camera.

The remainder of ucanvcam depends on the following free libraries:
  gd, freetype, SDL, YARP, wxwidgets
See DEPENDENCIES.TXT for details

== On Linux ==

To use with the skype beta current at the time of writing(version 2.0.0.43),
you'll need the "gstfakevideo" workaround (do a web search).

== Compiling on Windows with Visual Studio (Linux is easier) ==

You'll need DirectX installed.  These days, it is bundled with
the Windows Platform SDK.  Install that.

Compile using CMake: http://www.cmake.org
  cmake.exe CMakeLists.txt  

Chose any build directory you want, and configure.  Hopefully, DirectX
will be found automatically.  Otherwise, edit the two variables
DIRECTX_BASECLASSES_DIR and DIRECTX_INCLUDE_DIR by hand in CMakeLists.txt.  They should
look something like this:
  SET(DIRECTX_BASECLASSES_DIR "C:/Program Files/Microsoft SDKs/Windows/v7.1/Samples/multimedia/directshow/baseclasses")
  SET(DIRECTX_INCLUDE_DIR "C:/Program Files/Microsoft SDKs/Windows/v7.1/Include")

Configure again if you need to, then Generate.  All going well, you
should now have a "ucanvcam.sln" in your build directory.  Open
this, and compile.  All going well, you'll get a "ucanvcamx*.dll"
file.  There may be warnings about sprintf and the like.

Now, if you run "cmd.exe" with administrator privileges, you should
be able to do:
  regsvr32.dll ucanvcamx*.dll
and get a happy message:
  DllRegisterServer in ucanvcamx*.dll succeeded.

You should now have a functioning virtual camera, sitting and waiting
for input.  Try it out in e.g. amcap.exe.  There should also be a 
program called "test_bus.exe" to do a basic test of the camera.
Run:
  test_bus.exe image 320 240
and you should see a change in the image shown by the virtual camera
for a second or two.

To compile the ucanvcam GUI, you'll need wxwidgets (try installing
from "wxpack") and YARP - see:
  http://eris.liralab.it/wiki/Binary_packages#Install_precompiled_versions_of_iCub_and_YARP
  
Reconfigure, turn on "STANDALONE", "USE_GUI", "USE_YARP", recompile.
