   VFW or DirectShow
  Hy!I want to capture frames from my webcam. I've created the preview part of my program using Video For Windows. And I tried the AMCap (a small DirectShow app) too.The results: AMCap preview: 30 fps   My Program: ~10-15 fpsAM I doing something wrong? It seems that VFW is much slower than DirectShow.How can I make my VFW preview faster? Preview rate has been set to 30.
