[Vala] How to keep an object alive if it's going out of scope

["Jaap A. Haitsma" <jaap haitsma org>]

Hi,

I'm working on porting cheese to vala. I'm running into a problem when
trying to convert gst-audio-play.c [1] to vala.

The gst-audio-play has a function play_file and what it does is the
following in semi vala code

public static play_file (string filename) {
  var audio = new Audio (filename);
  audio.play (); // Playing starts in another thread

  // In vala audio gets unreffed here, but I want it to be unreffed
after it receives an EOS (end of stream) in the other thread
}

How can I get this to work in vala. I could ofcourse make sure there
is just one Audio object which I create at the start of the program,
but that has the disadvantage that I can just play one stream at the
time. I'd like to see that if a user calll play_file 10 times that she
hears the 10 files.

Thanks

Jaap
