libextractor

Hi all,

I need to extract metadata from an arbitrary file before accepting it,
and I was wondering if there is anyway to use this
http://www.gnu.org/software/libextractor/ from gst. Probably a *very*
stupid question, but since I never wrote a single C line in my life...

Good morning,
have you tried using this:

Thanks, it looks like this could definitely solve the problem (and a
number of others, for that matter). My last doubt is that this is all
very nice as long as I stay on *nix box, but it will probably put me
in the position of having separate releases for Win, *nix and MacOs,
or will it?

I think the DLD class is hiding the secret of how to load a library on a
given platform (and if it is .dylib or .dll or such). And the C mangling
is pretty much the same everywhere, or looks like it.
