Embedded multi media player in firefox

[Super Donkey]

Is there a posibility for this?

I have downloaded the codecs from some obscure debian source and the MAD
plugin for gstreamer. Also I installed totem-xine. Now I'm able to, in
theory, play any multimedia file using totem.

However I want firefox to know that I'm able to play those files and it
would be cool if I could use totem-xine as a replacement for
quicktime,real and windows embedded browser players.

I didn't see any extenstions on the firefox extensions that could do
it. But it shouldn't be to hard to implement (if I could program
I would do it my self now). 

But perhaps you already know of such an extensions that allows for this.

Skimming through the sources of a site to see the link to the multimedia
file gets annoying.
