What's your C experience? The way you ask the question suggests that this might be awfully difficult for you as a first project.

Go read some of the FFmpeg documentation or tutorials... if you're still lost, that's a good sign that you're probably not ready to tackle this quite yet.
If a general-purpose multimedia library is overkill for your purposes, there might be a simpler approach we could help with. Is this a specific project and/or video format you're working on, or is this just a general question?

Thanks for your support...
This is my first project to code a scene change detection algorithm in C...and I have no idea about storing of the frames....

Store the frames in a 2D array, perhaps. One element per pixel.
