We don't need a single all-singing, all-dancing wrapper library, but we
do need wrappers for something as simple as, say "play a sound".  I
don't want to have to deal with sinks and pipelines and all that.  I
just want to play a .wav file or a .ogg file or whatever when a user
clicks a button.

It would be nice if we had a nice generic video widget so all I had to
do would be:

        GtkWidget *window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
        GtkWidget *video = gnome_video_new ("pants.mpg");
        
        gtk_container_add (GTK_CONTAINER (window), video);
        gtk_widget_show_all (window);
        
        gnome_video_play (GNOME_VIDEO (video));
        
        gtk_main ();
        
but I am sure there are much, much larger issues involved here that I
don't understand.  But you get the point.  For your larger video editing
program, most of this stuff is too high level for you, and you need to
use the features of GStreamer.  But I just want to make a "SQUEAK!"
noise when a user triple right-clicks on my window.
