Have you tried to use the sample grabber filter to add to a frame counter variable for each frame delivered. You can then grab the count once a second and reset. I have used this method before, and if you just need it for simple debugging purposes it should be fast and accurate enough.

Hi BryanWilkins yes i did it before and it was successfully worked! you can add just a simple counter in your function that will be called when a new frame arrived, but there is a problem and it is that you need to calculate how much time it takes to add a new frame. :) fortunately you can do this by adding a time calculator to your function and for sure you can see your frame rate easily.

have a nice time.
ask me your question if you need to know more about directshow.
