Everything boils down to this little macro:
#define GST_GIO_STREAM_IS_SEEKABLE(stream) (G_IS_SEEKABLE (stream) &&
g_seekable_can_seek (G_SEEKABLE (stream)))

Which uses this little function:
http://library.gnome.org/devel/gio/stable/GSeekable.html#g-seekable-can-seek

Which checks G_IS_SEEKABLE() and returns can_seek property of the
G_SEEKABLE_GET_IFACE
So, if you want to know whether you can seek a particular GIOSTREAM or
not, get its sources and grep for "->can_seek".
