I think you need to specify the media framework in the codec part since
codecs are tied to a specific framework (e.g. gstreamer, xine and so
on). 

So it's just like how device drivers are tied to a specific (lineage of
the) kernel or OS (e.g. Linux 2.6, FreeBSD, Solaris).  Probably for
drivers it's sane to assume only one kernel is used though. But you
can't do that for codecs.

can haz codecs" application

  if (am_using_gstreamer) {
    pk_get_codec ("gstreamer-0.10", "audio/mpeg");
  } if (am_using_xine) else {
    pk_get_codec ("xine-xyz", "audio/mpeg");
  }

Or maybe I write

  if (am_using_gstreamer) {
    pk_get_codec ("gstreamer-0.10/audio/mpeg");
  } if (am_using_xine) else {
    pk_get_codec ("xine-xyz/audio/mpeg");
  }

I don't know. But your docs for this thing need to tell such
applications writers what to do.
