BMediaRoster select the best "Quality" reporting codec add-on after 
all of them sniff the media file:

This, in turn, call the add-on Sniff*() method:

This works with file-based medias.
However, there is also a SniffType(mimetype) method that codec 
addons can (should?) support, when 
the media don't come as a file (stream, in-memory media, etc), so 
meida kit can determine who's best "video/mpeg" encoder, decoder, 
writer, or reader add-on...

At least, it's what I've understand.

BTW, nice work contacting/involving/evangiling(?) MCF and xviD guys!
