Thanks Tanu for the reply, I wanted to test the module "module role cork" . So I started two media players using the gst launch tool. One had media role as phone and other had media role as music. When I tested using the "module role cork", it worked good. The player with media role "music" was paused. As the next step, I tested with two different players. 1) gst launch tool -- media role = phone 2) qt based application ( runs on phonon - gstreamer framework ) -- with media role as music. When the "module role cork" is used, the music stream is just muted but not paused. I tried with a few other players too. The low priority stream is just paused. I could not understand where the difference is coming from. Can you help me with this.
