Well, it's really easy. Every gstreamer plugin binary package will have
some custom control fields which specify what this package provides.

For example there's a field which contains all elements, a field which
contains all URI schemes from which you can read when this package is
installed and the capabilities of the encoders and decoders in the
package.

This makes it possible to enable automatic codec installation from 3rd
party repositories like Debian Multimedia for example.

Apart from that dh_gstscancodecs will now generate a substitution
variable that can be put into Provides and will contain stuff like
gstreamer0.10-audiosink. Previously we added this by hand ;)
