Get video info about total frames

[porro]

Hi.

I need to know, from a .avi file, the numbers of total frames of the video.

Can someone help me with the code?

Looking for it I found that in the header of the file we can find this information but I don't know if it's usually standard.

I found this: AVI Header Format

I'm just a beginner so every help is useful.

THX

Bye
