How to count the number of frames in a video

[snafubaby]

I have software called video to jpg converter by DVD VIDEO SOFT,which takes a video, and converts it to jpgs. I have a few options here. I can extract EVERY frame, or a certain amount of frames of the video. I could also extract every certain amount of seconds of video. All i need is a piece of software that will count the number of frames in a video. It would be very helpful to use with this program. Any help would be appreciated.

FPS x Duration = Total frames.
MediaInfo can give you both.
A calculator can do the rest.

Virtualdub can do everything you are currently wanting to do.

One thing i forgot to mention. The video is in .webm format. Will virtualdub be able to load it in?
