Metadata is definately something that should be done in GStreamer as well.  
For some reason we haven't gotten round to it - mostly because of 
differing opinions on how it should be done.  There are lots of ways to do 
this.

Insanely slow, that would be very surprising, unless you have actual 
numbers ;) First of all, it might not even be necessary to actually create 
a pipeline for it.  We're working that out currently.

Second, even if it were, how is this slower than opening the file and 
parsing data ? Because that's pretty much all the pipeline will be doing.

It'd be worse if a lib like monkey-media were *forced* to depend on *all* 
media libs out there, just to query for metadata, because that's exactly 
the issue that GStreamer is solving succesfully right now - being able to 
use a lot of libs, without forcing you to have them all to run your app.

IMO this is a problem that we should solve in GStreamer.  Jorn, you should 
join into that discussion (which I intend to restart now) because it's 
important for monkey-media as well.

This implementation should be done in time for Gnome 2.2 of course, so we 
might as well get started on it ;)
