In transmageddon I spent a lot of time trying to be able to get at codecs and
muxers by using GStreamer caps/mimetypes and link that with element names. We
got quite a bit of API in GStreamer for taking string mimetypes and using them,
but not a easy way to link that information with actual plugins.

In transmageddon I created this file to deal with it:

It is essentially an API which I can for instance provide with
'audio/mpeg,mpegversion=1,layer=3' and it will return me the name of a mp3
encoder if I got one, or let me know that there is no plugin for that format
available (which in turn lets me use the pbutils stuff to search for a plugin).

Would be nice to have a generic version of this API in C availalble in
GStreamer as loading of plugins and checking pad caps is not obvious to people
not very experienced with GStreamer.
