gapi doesn't have anything for this... you can only override it with the
.metadata files by hand for every value. We have this for many other enum
values at other places too already (to set the values of the GstEventType
enums, to set the Last element of a lot of enums, .....).

gapi isn't perfect and a lot manual work is needed unfortunately. I hope this
gets better once gobject-introspection is completely ready and we have a code
generator that uses it ;)

IMHO we shouldn't spend too much time on improving it when it is only for very
special cases and instead use .metadata or hand-written code.

Well, let's write a mail to each other whenever we start on a new library
binding ;) I'll do cdda/audio next...
