I'm sorry, but I don't quite understand what you're asking for.  What do you mean by "extract the filter"?  Do you mean 
remove it from a created graph, or determine which filter is being used?  Which filter are you referring to, there will 
be many in a graph?

Which define are you looking for?

Judging by the other posts you've place on the forum, you don't want to bother yourself with MMF at all.  If you are 
using MME, the control of playback is all done through the MMF APIs.  It should be much simpler for you that way.

The only time you need to worry about MMF is if you are writing a filter yourself for a format we do not support, or if 
you have decided for whatever reason, not to use the MME or io-media.
