Using DirectShow to 1) count frames 2) Grab a frame by index, not the time

Hi, I am writing an app that will extract information about movies. It should be able to get the ***exact*** number of frames in a movie and also it should extract a frame ***with a given index*** and store it as a thumbnail.

I'm pretty new to DirectShow, just went through that GrabBitmaps sample project. It's neat and all, but IMediaSeeking accesses frames through time, which is just not quite what I need.

IVideoFrameStep::Step looks great except that it works no faster than simply playing the movie (according to the docs, haven't tried it myself). 8 - (

Well, that's my situation. HEEEELPP!!! 8 - D
