Java FX - Audio & Video Formats

Just trying to play some media recorded via a MIDlet with the SimpleVideoPlayer demo app. It doesn't play 3GP, MP4 and AMR sound files - a core sound format on mobiles. Hopefully they'll sort this when JavaFX gets installed on devices. Can Sun not just talk to the folks at VLC player to get widespread codec support somehow?

Anyway here's the error from a AMR sound file (amr_nb, 8000 Hz, mono) recorded from a Nokia N80:

Error with Media: MediaError: media unsupported:com.sun.media.jmc.MediaUnsupportedException: Unsupported media: http://www.mobile-utopia.com/mobileblog/stuff/test.amr
