title: Live Webcam + Shader effects
body: <p>I want to create an application which basically captures a webcam feed and applies a custom shader effect on it, for Windows. I could use GLSL, HLSL, any shader language really.</p>
  
  <p>I've tried to use Qt, which has some <a href="http://doc.qt.digia.com/qtmobility/video-qmlvideofx.html" rel="nofollow noreferrer">very nice examples with QML and Qt Mobility</a>, but unfortunately, it doesn't capture my webcam at all! And I didn't really find any solution to my problem. I'm using Windows 7 64-bit.</p>
  
  <p>So my question is: what tools should I use to build a simple app for this quickly? languages, APIs, any tip is kindly welcome!</p>
