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?

From the FFmpeg download page:
FFmpeg Windows Builds are available at Zeranoe FFmpeg Builds.
You can link to these builds instead of compiling yourself.

From which directory are you trying to run FFmpeg? Did you follow step 5 in the how-to, "Edit the Windows System PATH"?
