AFAIU, decoding audio should be done using the DSP, like the gstreamer
plugins do that come with this device.

I've ported a KDE/Qt mm app to Hildon/GTK, but wasn't successfull in
building a gstreamer pipeline enabling video. Unfortunately the
current documentation only explains that what was already figured out,
ie. no info about setting the xoverlay/window settings.
There is also the osso-media-server, that is used by nokia's
audio-/videoplayer, controlled by dbus. I'm now using that  (see 
http://www.xs4all.nl/~jjvrieze/kmplayer_0.4.0-1.tar.gz, in
kmplayerprocess.cpp). Unfortunately, this is also not documented. I've
used dbus monitoring and 'strings' to get this working. Though the
video player may need some extra 'killall osso-media-server' here and
there. (Btw. I found this same 'killall' with 'strings' in the shipped
players, will auto restart a new one).

It would be great if this osso-media-server dbus interface would be
documented. Also because on such a device, having one media-server
makes sense to me.
