Just a quick roundup of some interesting developments I’ve seen recently in the world of persuing elegant cross-platform solutions for media players.
Songbird is a media player in the vein of iTunes that uses XUL
http://xullicious.blogspot.com/2005/06/xul-music.html is an example of how to make a cross platform media player using gstreamer and directx for the application, and XUL for the front end.
Zap! is a XUL based SIP (ie, VoIP) client for mozilla. Basically a cross-platform streaming audio tool using the PortAudio audio library.
