In short, you can't. Someone needs to fix the mimetypes for this to
work. I'll see what I can do the next few days, but a lot of
encoding/muxing plugins need love and we'd better concentrate on
playback too, since Gnome wants a new 0.6.x release.

Anyway, see gstreamer/docs/random/mimetypes for a list of mimetypes per
media type, you can implement a few things yourself too, if you feel
like helping out. :).
