GStreamer still alive even after popping the component.

[prasadsawant5]

Hi, I have been successful in streaming an RTSP stream using GStreamer. However, when I pop the component, the video still plays in the background (I'm able to hear the audio even after navigating to the previous screen). After this, if I try again to go to the component containing the GStreamer, the app freezes. Below are the logs.

I suspect that after the component is popped, the GSTreamer is not killed which is causing the freeze when the same component is rendered the second time.

Thanks.
