Flash Media Live Encoder - plugin development

Hello there community!

I'm quite new to these forums, but spent a good deal of time reading and searching just now, just don't really know where to begin.

Allright, so i'm searching for information on how to write plugins for FMLE 3.0, the reason is that i need to extend some functionality regarding the metadata injections.

So, does anyone here know of an API/Framework/SDK like paper that is a good place to start reading?

Any input will be welcome, except "nay sayers" because i know it's possible to make plugins, ive seen one or two out there, just dont know where to start.

PS.

I have plenty experience in writing DLL's for windows applications, but i would rather refrain from reverse-engineering FMLE to use windows hooks and insert dll's at run/loadtime, would rather have a more or less "intentional" framework to work with.
