title: ISampleGrabber deprecated?
body: <p>I have an old computer vision experiment that uses Video for Windows to grab frames from a camera connected to the PC.  It's a hack, it uses VfW to create a preview window, then it does a GetDIBits from the window DC.</p>
  
  <p>I'm finally ready to port this to DirectShow.  My understanding was that I could grab frames from a video capture graph by using ISampleGrabber, but now I read that <a href="http://msdn.microsoft.com/en-us/library/dd376984(v=vs.85).aspx" rel="noreferrer">ISampleGrabber is deprecated</a>.</p>
  
  <p>What's the non-deprecated way to grab frames from a video feed?  Do I have to implement my own DirectShow filter that does essentially what ISampleGrabber does?</p>
