You'll need a few things to do anything with this. - JDK 1.3.0 or better - JMF 2 or better (java.sun.com/jmf/) - Eclipse (www.eclipse.com)
Eclipse is the IDE which I use... I don't personally care one way or the other if you use it, but you'll need the SWT package from it for parts of the user interface of VideoMOn, it's way faster than AWT or Swing, and (IMHO) more elegant as well. (I would recommend using Eclipse as your IDE, unless you're already proficient in CVS, or you feel adventurous :)
Right now, the program won't do much unless you've got some VFW compliant capture device; I'm planning on adding a support to use prerecorded video files as a pseudo capture device, for testing and development purposes.
Oh, and don't worry... this is nothing like what the normal web site will be like :)
